Cannot set up cellular on Series 3: Says AT&T not supported

[dave006]

I'm hoping they don't have to delete the line. That's an old number I ported over and saved it so I would rather not lose it.

They said they would call me back today so I'm hoping that it's just a profile issue that needs to be reset. I will powercycle her phone and watch, unpair it and then remove the data plan and do it all over again in hopes of that correcting it.

Thanks

OK just to be clear what we are discussing. The number that you want to attach to the $10 wearable plan is an old phone number that you have been keeping. No worries in this case the rep should be able to do some extra work to clear anything pending for that line.

Normally all the plans for the wearable plan are using new random numbers. So we just tell the rep to just delete the line and not worry about an extensive search to try to resolve issue. Not trying to be rude but you do know that the number assigned to the watch can't be used for anything more the NumberSync. There is no way to make incoming calls that complete or outgoing call from this number?

Yes that is another mess. I would call and ask the rep to check on any pending activations on the line. If the story they told you last night was true then you should have received 1 or more emails or texts telling you something about NumerSync.

Be flexible with the rep but I am going to bet that you will to remove the Plan listed in the Watch app and trying again. I always suggest a power cycle of your wife's iPhone and watch and trying again. Worst case is to go Nuclear and also delete the line from the account and have the rep setup a new line and associating the EID and IEMI all over again.

Kind of rinse and repeat.

Well I am flying blind from here since my Nike+ does not get here until Oct. 5th. We now have some more data points on our quest to figure out SMS/MMS Txt messages really work. See the usual story at the bottom..

So how does it work for the Apple Watch Series 2, I would think it would be in the same list as your iPad for Setting Message forwarding. The iPhone would forward the SMS/MMS messages via Apple Continuality ( in this case via iMesage ) as far as setup on the iPhone.

The real challenge is that the original inbound SMS/MMS message is addressed to the iPhone number so that makes sense that it is expected to be on in order to route the SMS/MMS to the watch. The magic or non-magic of NumberSync.

We do know what AT&T insists: SMS/MMS text messaging requires that your synced smartphone must be powered on so SMS/MMS messages may be forwarded to your watch. iMessage must be enabled and your smartphone must be connected to the AT&T network via either a cellular or Wi-Fi connection. If using a Wi-Fi connection, your smartphone must have Wi-Fi calling activated.

Dave

Well apple pointed me to this article... https://support.apple.com/en-us/HT205547

He then tried to tell me SMS will not work when away from phone. However, if you read the first section it says ...

"If your iPhone and Apple Watch Series 3 (GPS + Cellular) are both connected to a cellular network, your watch can do everything that it normally does, even if your iPhone isn't with you. When your watch connects to a cellular network,

appears in the Control Center.

If your watch is connected to a cellular network, but your iPhone isn't, your watch can do the same things that it can when using Wi-Fi."

It says right there that if both devices are on LTE everything should work. He tried to tell me no because I am away from my phone so SMS will not work because its not connected to the phone. I am so frustrated with these people... it seems they have no idea how to support the watch. I am just going to have to go into the Apple store I guess. This is ridiculous.

 

[Libby55]

I spent some time on the phone with AT&T. I had given the rep the EID number and the immigration numbers. Then he wanted the incident number. Not one on my watch app in watch or iPhone. I told him it has an embedded sim. I was then told I had to go to the store to have it set up as they cannot do it from their end. He is going to send the instructions via E-mail if I wanted to try to set it up myself from home. But he told me I would be better off going to the store because it was such a long process.
Any thoughts?

What a mess but classic in today's tech world. The folks that are charged with supporting a product tell us one thing about how the product was designed to work and the Documentation defines a different use case.

I wish you luck at the Apple Store but I expect you to return with yet another version of the "Truth". Let us know when you have an update.

Well, that didn’t work. She left the house, was on LTE, & she got the same message about HD Voice

Ahh, I was hoping for a higher batting average today. I know I mentioned it in one of my posts but it has been a crazy 128 hours (or it feels like it) but I am not sure we actually verified VoLTE is on.

Please have her go to Setting > Cellular > Cellular data slide ON > Cellular Data Options > Enable LTE should show Voice & Data just to verify it is set.

Yes, please let's see the email with relevant data removed: email addresses, names and any phone numbers. This would be a fun exercise.

Now back to the real world, the rep did not need to touch the eSIM data. The ICCID is generated during the setup of cellular on the Watch app in concert with AT&T's systems. The rep just needs to "Park" the EID and IMEI from the watch to the line that will be the $10 Unlimited Wearable plan.

Where did you delete the cell plan, on the Watch app or on your wireless account?
So what's the error message now?

Dave[/QUOTE]
Cell app

 

[dave006]

Cell app

That's what I thought but wanted to verify. So again what specific error to you now get during setup.

Dave

 

[dstew201]

I have been dealing with a multitude of issues since day one, I wanted to provide my resolutions.

Problem 1, I have 8 lines on my account. During setup the first time in store I was informed Line 9 requires a deposit.

I first called and was told I would be shipped a SIM card have a nice day click.

I then went to an AT&T store, spent some time there, begrudgingly agreed to pay the $150 deposit but fully intending to call and complain later.

The store rep got to the last step of entering my IMEI and EID and it failed saying it was already active on another subscriber.

Problem 2, I stayed in store and called customer service. Thanks to this thread I explained what needs to be done. Eventually she agreed to connect me to "Level 2" support. Level 2 support performed whatever reset they needed to do then ran into the $150 deposit again.

Back to problem 1. Level 2 support explained the issue with the deposit then connected me to activations. The activation man found some pending line on my account (probably the original) and was able to bypass the deposit. He entered the IMEI and EID, said it appeared good. I went into the cellular setup on the watch and still received an error "Something went wrong".

A couple hours after I got home Level 2 support called me back to check in and make sure everything was working. I told her the line was created but it still wasn't syncing. She tried numerous things, a reboot, everything. At one point I had a screen under cellular that showed an AT&T plan "Not In Use". Every time I tried to go thru the steps I could log in but it just took me to the main account screen. Eventually it was 10 pm and I had to hang up with her.

Today I tried yet again. Somewhere along the way of doing the resets I removed the plan from the watch. This required AT&T to refresh my EID and IMEI in the system to readd it. I still got stuck on the "Not In Use" Screen and couldn't get it then the numbersync setup

That brings me to

Problem 3. Possibly the biggest culprit of them all. I had a plan. I had a number. I had a "Not In Use" AT&T plan on my cellular tab. Every time I would tap setup cellular I would login and it would just take me to the account home screen instead of the prescribed 911 warning screen. I tried going to my line and setting up that way but it asked for a code.

Here is where all my secrets come out. I am an AT&T employee. I work for the DIRECTV division so I have no interaction with the wireless side or "special people" I can call. I have what is called a legacy DIRECTV employee account and an AT&T EMO account. Both are associated with my personal email address and because of the types off accounts they can't be linked together. Each time I log in I get a screen asking me which account I am trying to log in to, including when I tap "Setup Cellular".

I suddenly had the idea to change the email on my DIRECTV account. I was already mid process on unpairing and re-pairing the watch. I got to the cellular setup, typed in my login, this time with no prompt to choose which account I wanted to log in to but a 911 warning confirmation! A couple prompts later and BOOM, IT'S WORKING!

Hopefully this helps somebody.

I went thru the same thing!!! if you look back a couple of pages, too bad you didn't probably could have saved you some time...once I separated my DirecTV and AT*T account (synced id and password), it just worked!!!

My watches (Series 0, Series 2, and now Series 3) have never shown up in the text message forwarding setting, but I can verify that I do get SMS/MMS messages on cellular when I'm away from my phone as long as the phone is on. The reason I have been told in the past that it doesn't show is because unlike your iPads or other iPhones on your iCloud account, it is always enabled by design of the watch. Back with my Series 0 and Series 2, I would get my SMS/MMS over wifi when I had the cloud icon in the control center instead of the phone icon

 

[sdsvtdriver]

So what does it how when you log in to myAT&T now, a phone number with the correct AT&T Unlimited Wearable plan? We don't really have any way to see if the EID and the IMEI is correctly "Parked" on the watch's line.

It is always possible that they have closed the door on doing this using the automated method. You might consider swinging by the a Corporate Retail location, they can also add the wearable plan and get you to a state where the next time you run Setup Cellular for the watch you will be ready for the NumberSync steps.

Since you brought up Retentions, for others following along, don't go there if you want changes made to your line, account or wireless feature's. They are great about getting credits or pricing or to help you leave AT&T.

Dave
[doublepost=1506530109][/doublepost]
Where did you delete the cell plan, on the Watch app or on your wireless account?
So what's the error message now?

Dave

The portal shows the plan and a dummy device (some LG tablet). I'm guessing my watch's ID numbers are tied to a device activation that isn't happening at this point.

I called in again to get a status. I was told the wearable plan has to be added to a mobile share plan and that's why it won't work. I stated it will work with the GUDP and was told their information is that it won't and my only option was to switch plans. I told the rep to remove the wearable plan and ended the call.

I give up.

 

[southerndoc]

So now it says set up cellular, and when I click it, I'm given the option to set it up as a new or to replace a sync'd device. When I choose replace, it gives me an error adn tells me to power cycle the device.

More specifically, I'm getting: "Oops! We've hit a bump, but we should have it straightened out soon. Please power off your device, power back on, and try again. (SVCEMSI02)

 

[HeadphoneAddict]

In the case of the LTE watch there is no SIM but an eSIM (embedded SIM). The ICCID is generated and stored in the eSIM as part of the cellular activation process. In the old days a SIM is physical little card with a chip. The ICCID is a preprinted number that is unique on the face of the SIM. So by now most people just equate SIM & ICCID.

You should be added as an authorized user just in case you are challenged at a retail location.

Do you have your own Access ID or just a User Id? I would suggest that you swing by this link and create an ID specifically for completing the NumberSync during activation. Please note that you need to use your iPhone phone number and the last 4 digits of your iPhone's IMEI. If it says your iPhone is already assigned to another Access ID, use the second link to find the Access that owns your iPhone. Use the links in the gray box on the left.

Did you verify by logging in to myAT&T and seeing your iPhone listed first in the Devices because this error does not appear to agree.

I am trying to use terms that most reps know or hear in the course of their day to day job. The term "Park" dates back quite a ways but is the best term that I have found that works. You could always ask the rep to create "a new line with the appreciate Wearable plan based on the device information that is $10, here are the EID and IMEI numbers from the wearable device to be assigned to the new line".

Well we should not have to do any if the crazy hoops that we have been doing since Friday, cellular action should have just worked the first time. However, we have not been that lucky and most customers don't want to wait some random number of days for a fix that may never happen because the rep is just making stuff up to get you off the phone. If you look through the Thread we have had some crazy random things break the Workflow process. The best ones are the stories that the fix will on Monday, Tuesday and the latest was a claim that all would be good by 9/29 or just wait until your new iPhone arrives late in October while just pay the $10 for a watch you can't use.

Dave

First, to clarify, when I log into ATT.com we have an ATT access ID (letters then numbers) which I know is tied to my wife's cell phone, because to the right of her Access ID listed on the page it also says "Or, log in with xxx-xxx-xxxx" (her phone number). I also have a log-in as an authorized user and can log in with my alpha character (no # in it) username or ID, or with my phone number, using my unique PW for either login ID.

Up until yesterday our account had the iPad mini 4 as primary device for the 30GB mobile share data with rollover, as seen on our monthly bills. But it was never first in any list I've seen. When I went to the store they said they didn't know how fix it and still keep our Promo price on our "Mobile Share value 30GB with rollover data" plan, and they called ATT on my phone for me. After we were done, the ATT rep on the phone swore to me that my phone number is now the primary device (she read me back the number).

Then, at night when I had tried the number sync login during setup, the only login that was recognized the first time was my wife's access ID version (not my login with name or number). Prior to yesterday I didn't even know my wife had a login Access ID at all, but I had looked it up after reading all the issues in this forum.

The first time I got through the number sync process on the iPhone it processed for a while, and then the first error # that I posted (EAPS360003), and I called ATT for help, as described in my previous post. After that I got the EDS4007 error the next time I tried at 10PM mtn time, after ATT shuttered their doors for the night. Also, the rep last night who was going to add my EID and IMEI and assign a number did warn me that it would be $10/mo, but then her systems went down.

Right now, when I log in to ATT.com with any of the logins we have, we get to the same account with all 11 of our devices. If I go to "view profile" I see my mother-in-law's iPad mini at the top of the list, and if I go to the drop down menu "manage my device and features" I see my son's iPhone as first in the list from left to right.

If I click on the big box on the top right of the main page that says "My Wireless" it drops down more boxes that show "My Usage" and "My Plan" and "My Devices (11) & Plan". In the My devices and Plan box, my wife's iPad mini is still first in the list from left to right.

So it sound like everything I did at the store yesterday was for naught, and everything I tried to get them to do on the phone last night after step one was also for naught. Does this mean I start over from Square One?

 

[HPLouis]

More specifically, I'm getting: "Oops! We've hit a bump, but we should have it straightened out soon. Please power off your device, power back on, and try again. (SVCEMSI02)

That’s the first error message I received.

I then hit OK and I saw the EDS0219 error

 

[HeadphoneAddict]

Called ATT just now, explained everything to the rep, and got disconnected right after I finished explaining the issue with having an iPad as primary device on our data plan - no "call dropped" message on my phone, just disconnected and no call back. Grrrr... Calling again.

 

[HPLouis]

OK just to be clear what we are discussing. The number that you want to attach to the $10 wearable plan is an old phone number that you have been keeping. No worries in this case the rep should be able to do some extra work to clear anything pending for that line.

Normally all the plans for the wearable plan are using new random numbers. So we just tell the rep to just delete the line and not worry about an extensive search to try to resolve issue. Not trying to be rude but you do know that the number assigned to the watch can't be used for anything more the NumberSync. There is no way to make incoming calls that complete or outgoing call from this number?

Dave

Hi,
I know the number won't work anymore but I just want to keep it. It's one of those rare NYC 212 are code numbers and I don't want to lose it.

You need to see this https://en.wikipedia.org/wiki/The_Maid_(Seinfeld) The episode featured the New York area code 646. When the 212 area code ran out of numbers, 646 was created.

@Dave - I'm on the phone with ATT rep, and he says the rep on the phone last night put my IMEI and EID into the system as an iPad instead of as a wearable, and that's why her system was giving her errors too. He confirmed that my iPhone 7+ is the primary device on the account. He's fixing it now.

"Does my iPhone need to be powered on to use talk, text,* and use data on my Apple Watch?
You can use data and make and receive calls on your watch even if your iPhone is off. However, in order to send or receive text messages your iPhone must be on and connected to the AT&T network."

So, if my phone is turned off or in airplane mode I'd expect to get an inbound call on my A Watch3. However, I find that all such calls just go to voice mail!

That's a fail.

Yes yesterday I had many problems getting numbersync and cellular connectivity. Now every time I reboot or restart my phone from airplane mode AT&T sends a text message that says it is active with my wearable.

Still it doesn't help if one I cannot turn off voicemail (voice mail is a failure case and unnecessary) to force it to forward.

Or do I need to setup a permanent forward to the "hidden" number on my account for the Apple Wearable to cure both the useless voicemail and make sure I still get calls if my phone is dead and sitting at home or away from me while I'm on cellular or Wifi?

Anyone know?

Thanks

No problem that is what I thought you were doing by saving the number. Please be very cautious with this phone number assigned to a secondary device i.e. not a cell phone. This can be an issue if you later want to port this number for any reason.

Did you ever get an email or text that NumberSync was complete. To make or receive cellular calls on the watch, NumberSync has to be complete. Your experience indicates that NumberSync is not complete.

That is the reason that I keep typing over and over about the $10 Unlimited Wearable plan. The iPad by the way is $20 per month. Maybe the rep was trying an upsell.

Once you get the wearable line correct, let's get past the list of 11 devices on your account. Follow this link to create a specific ID to manage NumberSync for just your iPhone and watch. Please then use this new ID to log in during the Set up cellular step for your Watch app on your iPhone.

I now have the same problem!! The rep has been very helpful, but is telling me right now on the phone to go to the store to pick up a SIM card so he can park the line, and I'm reading his these posts explaining that HE DOESN'T NEED a Sim card with an ICCID because it's a Wearable with an Embedded SIM! But his supervisor and the system is telling him he does. But I don't need the "$10 Unlimited Wearable Plan" like the gentleman above, I just need it parked to my data plan.

I'm now being transferred to the apple tech team at ATT, after 1 hour and 18 minutes on the phone with the second rep of the day (1st one hung up by accident).

Politely ask them how you would install this SIM. The wearable does not have a SIM slot of any kind. On your plan you still need a plan entry for the phone number. In your case is should say something like $10 "Shared rest of your data plan name" access fee. Going to a Corporate Retail location might be in order but not to get a SIM.

[montpyt]

Does anyone know how to resolve the e911 address issue. If you are not familiar, I set up cellular, log into numbersync and it brings me to the 911 address screen. It has my old address, so I change it to my current address. I hit ok and I get an error that they could not verify the address. I try again and keep my old address and it still says it can't verify the address. I go onto the phone to double check the emergency address and the numbersync address under wifi calling. The change address option has my current address. When I click the change numbersync address, there are about seven different Apple Watch options as well as my phone and other devices set up for wifi calling. I check each one and they all have the same current address.

1. How do I get the address to verify when confirming the address in the numbersync portion of the set up cellular in the watch app?

2. How do I get rid of all the Apple Watch options under change numbersync address on the phone? No wearables show up on the ATT web site under numbersync wearables

 

[jmm1947]

I'm on with AT&T now. We've moved from stuck "Activating..." to the EDS0241 error. Mentioned TORCH to the rep and he's investigating but not familiar with it himself. Does anyone know what TORCH stands for?

EDIT: We've moved on to EDS4007 now.

EDIT: Back to the original error of EAPS360004 saying rate plan incompatibility, followed by EDS0218 "Oops..."

Agent stated the first error says I need mobile share plan or new unlimited (I passed) and second required him to submit a ticket (He did).

Now I wait.

I fixed my EDS0241 problem by turning off roaming: "iPhone > Settings > Cellular > Cellular Data Options > Roaming Off". I was then able to use "iPhone > My Watch > Cellular" to connect my Apple Watch 3.

For anyone who actually has their watch fully working... are you able to send regular (green) SMS when away from your phone and connected to LTE?

His system refused to let him "park" the EID and IMEI number on a $10 wearable data on my plan. Now on to Apple watch support at ATT.
