Verizon 5S on AT&T, replacing/activating a "defective/new" AT&T SIM?

For those that are using a Verizon 5S on AT&T...

How are you going about activating a new/replacement AT&T SIM with a Verizon branded 5S?

Any issues with AT&T CSR questioning the Verizon IMEI?

Does your Verizon IMEI match on AT&T's network?

None - I just swapped the SIM's. Didn't even call AT&T.

The only issue is the apps which aren't loading on my phone from a restore (prob. because I used different Apple ID's to download them).

I did the same with my i5..

Does your Verizon i5S' IMEI correspond correctly on AT&T's network? (Mine doesn't match, could this lead to issues, like those with AT&T i5S IMEI miss match, rolling between LTE and 4G connections)

They don't care whether it's a "Verizon," "T-Mobile," or "AT&T" model.

...the network doesn't care, but AT&T CSR might give you a hard time.. Called last night to confirm/change my IMEI and SIM. When they asked for the IMEI they wouldn't change it due to the i5S being a Verizon device. Trying again maybe better luck with a different CSR..

My iPhone 5 has AT&T LTE and always go to 4g when on a call. I thought that was normal.

Keep reading, towards the end of the thread.. (It's not related to the LTE to 4G toggle while on or after a voice call)

IMEI miss-match could lead to authentication issues on AT&T's network (so far, only a few AT&T branded i5S are experiencing this issue).. I personally haven't had any issues with my Verizon i5S, but just in case, just wanted gather some input from other hybrid i5S users..

Good luck!

I have both networks, so I just added a new Verizon line..

Called in yesterday.. Spoke with an AT&T TSR that was willing to work with me to discover a few things about our hybrid i5S..

When they attempted to change the IMEI on file to correspond with my Verizon i5S, the system wanted to remove my data plan with no alternate data plan to select. The AT&T system did not recognize the IMEI as valid device to change too.

I was able to active my new SIM card without making any changes to the IMEI on the account, thankfully with no hassle.

When I asked the rep to read me back my listed IMEI, the system stated that it is an i5S, but who's, not mines.

My question to those that are in the know. Does the Verizon i5S send the AT&T network a different IMEI other than what is listed on the phone, perhaps the GSM version of the Verizon IMEI?...

When I swap my AT&T SIM into a prepaid ZTE flip phone, AT&T system has the same IMEI as the reported i5S, but states it's an i5. (My old i5 does not correspond with the IMEI on file)

(The phone pictured on my account is correct, the i5s)..

Going to pick up an AT&T N3 to see it the system will update its IMEI and then swap back to the i5S to see if that mysterious IMEI replicates back to the system.
