As the title says, I switched from AT&T to Verizon yesterday. I got the iPhone X through the iPhone upgrade program on AT&T, so I received the A1901 model. After I had switched to Verizon, I remembered hearing something about the difference in modems/radios between the A1901 model and A1865 model. Apparently the A1865 model supports more frequencies and bands, and it’s the model I would’ve received if I had originally chosen Verizon as my carrier. My question is; am I still getting the full benefits of Verizon’s network on my A1901 model? I don’t want my carrier switch to be for nothing...

You'll lose any 3G fallback on verizon with that model, as it doesn't contain any CDMA radio chips.

You can always switch back if you're within the time frame where you can change your mind. Your phone will work fine on the T-Mobile network but as the previous reply stated, not with Verizon.

Gotcha. I've heard similar things about that. I made a call the other day to test, and I still had LTE data while on the call. So basically, if there's no LTE available and I make a call, I won't be able to use data while on that call?

If there’s no LTE available, you won’t be able to make any calls whatsoever. You’ll get a “no service” indicator.

Wow for real?? Even on 4G? Guess I should've thought this out before switching carriers :confused:

If it makes you feel better I haven't seen anywhere in years that has "3G" on Verizon. It was always slow, which is a reason they pushed for LTE so hard. Going back to that point, even the very very very odd place that only has 3G will be extremely painful to use even with a phone that can access it.

There’s no such thing as 4G. It’s a made-up name carriers use to designate their fast 3G systems (versus the original slower 3G systems).

Your phone model does not have a Verizon-compatible 3G modem. You will not get any 3G or “4G” signal. If you don’t have an LTE signal available, you’re SOL.

Granted, in your geographic area it may not matter if LTE is ubiquitous. But if you go out into the boonies, you won’t get any service.

Yes. It is real :) Gather as much information as possible before switching carrier. MacRumors has a lot of threads discussing model difference between Verizon/Sprint phone and AT&T/TMobile phone. You just need to be patience for finding these threads. Good luck!!

That does make me feel a little better!

However, I noticed in my cellular settings that I no longer have the option to enable or disable LTE...

Thank you for the information. That really sucks for those that got an iPhone model on AT&T or T-Mobile and want to switch to Verizon or Sprint. Thinking I might go back to AT&T until next year's iPhone.

At some point, Verizon will turn off their legacy CDMA 3G system after they convert those towers to LTE. So like I said, may not make a difference for you in your location... only way to know is to test it out.

Verizon CDMA/2G works fine for phone calls when there is no LTE coverage, which is kind of the point.

They are supposedly shutting it off by the end of 2019.

Really?

Have you told the International Telecommunication Union that their definitions of 4G are made up?

One of the reasons I went back to ATT. 3G on Verizon is unusable and for some reason I was getting it a lot once I left my home area. And I also found their LTE not as fast as people claimed. But YMMV.

How long you have had your iPhone?

Apple told me if I switched carriers WHILE BEING PART OF IUP, I could take AT&T phone to Apple Store and exchange AT&T 1901 model phone for Verizon 1865 model.

Otherwise, switch back. I haven’t found significant advantages to my recent switch from AT&T to Verizon phone and service, although I did see a 3G svc signal recently pop up during holiday travel thru the boonies.

You can just bring the phone back to Apple and exchange it for the A1865 CDMA model if you run into any situations where you need access to the 3G network. But like other's have said, it's basically unusable.

Verizon 3g must be way different where you guys live. While it’s definitely slower than lte or 4g, it’s hardly unusable around here.

Agreed, I travel a lot and 3g is pretty much still out there, even at my house which isn't in the boonies (north Tampa). 3g is very usable, specially if that's what you get, now 1x (2g) is also still out there and only good for calling.

Yeah, but as far as I know they will be keeping 3g until at least 2021.

Verizon is phasing out its 3G network and will shut it off entirely in 2 years. This is the first year they will activate phones without CDMA (though previously you could use a SIM activated with another phone) so they must have confidence in their LTE coverage.

Where are you getting this?

Everything I've read and answers I get from Verizon is they haven't any end date but not before 2021 for a 3g sunset.

They're confusing the 1x/2G shut off with the 3G one that is in 2021. BUT Verizon has already reformed a lot of its 3G network into LTE, especially in major metropolitan areas.

Agreed; but as someone who travels the US around 40,000 miles a year by road (avoiding Interstate) I estimate about 20% of the time I'm still on 3g.

Also can agree: it will sunset :).

“4G” = 3G HSPA. LTE was supposed to be 4G, but certain carriers who were far behind on their LTE networks basically forced the name change from 3G HSPA to 4G, thus LTE became “4G LTE”.

Back in the day, my iphone’s AT&T signal changed from “3G” to “4G” after receiving an over the air carrier update. Same phone, same network, new name.


E (EDGE)

E stands for Edge, Enhanced Data rates for GSM Evolution. It is pre 3G technology and again, more likely to occur when you are in a weak signal area. You may not be able to effectively browse the internet on your device, when getting this signal.



3G (Third Generation)

3G is the third generation of the mobile network and provides adequate signal strength for browsing the internet. Most smartphone devices have the option of 3G fallback, and 3G network towers are available in nearly every city nationwide.



H (High Speed Packet Access)

H stands for HSPA, High Speed Packet Access. HSPA (or H) is considered an advancement of the 3G networks or "version 3.5". It offers a faster network connection than the 3G network.



H+ (Evolved HSPA)

H+ stands for Evolved High Speed Packet Access. The network created before the emergence of 4G. It offers the fastest maximum speeds of all 3G networks (including 3G and H or HSPA).



LTE/4G (Fourth Generation)

Stands for fourth generation of the mobile network, and is also called LTE or Long Term Evolution. It offers the fastest maximum upload and download speeds of any network. For a network to consider itself 4G, it must meet the standards of the ITU or International Telecommunications Union.

Keep in mind, many H+ (HSPA+) networks mimic the speeds of 4G (or LTE), but because they do not meet the ITU requirements, they do not get the title of “LTE”.

That may be when they stop selling phones with CDMA radios.
