HP Elite X3 on ATT prepaid network
My iPhone SE finally died, and I have an HP Elite X3 I used on an ATT plan a few years ago.
Both are Nano-Sim phones so I swapped the sim into the old HP, ran the device through several updates, still cant pick up the service.
I went to my devices in the prepaid website, and updated my IMEI #, yet still no reception of service.
The sim is installed correctly, the device is as up to date as it can be, the IMEI is updated on my prepaid plan, yet I still cant pick up any service. Is this device still compatible with ATT's service? It has all the correct bands and is 4g capable.
Any input is appreciated.
