When will OnePlus 3 IMEI be added to AT&T Database?
How long until AT&T updates their IMEI databases to include the new Oneplus 3 Phones?
When I went to put my SIM card into my new OP3, I lost LTE speeds as well as had my data plan removed from my account. AT&T Techs and Store Employees both said it was because the system doesn't recognize the OP3 and assigns it as basically being a 3G flip phone. Because of this, the system changes our plan automatically from unlimited data to 300MB pay as you go.
I had LTE working in my old phone and in the OP3 for a short time until the system updated and deleted my data plan. I got it back but there is nothing that can be done unless AT&T updates their side of things.
Are there any other options short of returning the phone?
