AT&T No service

[KLit75]

Resolved. Quick phone call to carrier. Needed to be activated with a signal.

Did anyone here with AT&T have a hard time getting the phone to activate?
I set the whole thing up over wifi with no Sim and used it for a couple of hours with no issues.
I needed my working phone for work so I didn't insert the Sim. When I got home I popped the Sim in and there was no service.
I tried inputting the apn and settings manually. The service would pop on then turn back off. I reset network settings. Didn't work.
I factory reset. Didn't work.
Of course a series on reboots, insert/eject Sim...
I've needed to do some work to get phone's activated before but this is different. The wifi turns itself off. The mobile data toggles on and off. And it heats up a bit. I tried doing a factory reset with Sim inserted but then when I tried to set it up, it could not connect to wifi with the Sim inserted. Remove it and wifi works again.
Im probably gonna go to AT&T tomorrow but this is weird. The phone is brand new.
Just thought I'd put it out there. Thanks

I'm on cricket. Only challenge was to provide cricket with an iphone imei so they could activate volte. I get volte but no wifi calling.

What device are you coming from?

Oneplus 5t. Pretty sure all I had to do was pop in the Sim.

I've had the OnePlus 7t (HD1905) for about 4 months now. Using AT&T and have had no problems at all with it. Popped the sim out of my OP6 and into the OP7t without skipping a beat.

That was typically my experience too. But I even put the sim in my son's unlocked phone and it did the same thing. It was actually a relief because I thought that probably meant it was on the carrier's end. It was. I called tech support and they resolved it quick.

AT&T worked for me, excellent data speeds, and great signal. But at times it would go from 4 bars to absolutely no signal, and lots of dropped calls. After that I went to Verizon, not as good of signal, slower data, but no dropped phone calls or mysterious total loss of signal in an area where it should have been 4 bars.

Ever find out about this? I've been using my OP7T with AT&T for a few weeks and once in awhile have this same issue twice now. Nothing you do restores it, but it finally starts working on it's own.

May sound like an odd question, but since some of you guys are using AT&T, can you share your APN settings?

My OP7T is having some weird issues where the wifi hotspot just stopped passing data to any device connected to it. I've reset the phone, all the devices, and tried every combo of APN settings I can find, but it just won't work. It worked fine for months, then nothing.
