AT&T not recognizing my AT&T device

[Matthew Stegman]

My S21 ultra is showing up as 5G BYOD smartphone on AT&T. I recently switched from iPhone to Samsung. I've spoke to many representatives and they can't see to figure out what is going on. They even acknowledge that it shows up on there end as an AT&T device. I fear that since it's not showing up properly it's keeping me from getting software updates. I'm still on Android 11 September 1 2021 security patch.

Is it an AT&T S21 Ultra, or did you get it from somewhere else?

 

[Matthew Stegman]

it's from AT&T. the rep on the phone confirmed it.

 

[Matthew Stegman]

I'm good on updates. I set the date on my device a week later and that pulled all the updates.

Let's rephrase the question, did you purchase the device from AT&T or from somewhere else?

Can you show a screenshot of your software page ?

Go settings >about phone >software

 

[Matthew Stegman]

Here you go

Here's the updated one

Its definitely Att device, you on installment plan with them , never seen a lock on Att phones until its paid off must be something new , similar how TMobile has device unlock app until device paid off

Did you change the date/time back to Automatic? Sometimes, the wrong date/time can mess things up with the network.

 

[Matthew Stegman]

I set time and date back to normal.

AT&T still can't figure it out. Yes I am making payments on an iPhone still but that's never been and issue. I've used a unlocked Verizon phone on my account and it showed up properly. it showed device name make model and everything.

You can try flashing the firmware again

I talked to supervisor from AT&T and they think it's an internal problem.

Att doesn't recognize my pixel either. I phoned them to get it updated so they won't cut me off and they manually put it in. Still shows unknown in my account.

So what's the plan?

 

[Matthew Stegman]

Ok keep us posted

 

[Matthew Stegman]

considering flashing unlocked firmware tonight. thoughts?

this issue is still not fixed. My S21 ultra 5G is AT&T branded and shows up on my att app as a 5G BYOD.
