AT&T officially unlocked phones - software limitations and update problems
I live in Europe and I have purchased three phones that were originally sold by AT&T, both of them officially unlocked.
The first one is a Sonim XP8 and the problem that i have with this one is that I can not use the hotspot feature. From what I understand this feature was restricted by AT&T so that an additional data plan had to be purchased. Sine the phone is no longer locked to AT&T I think the hotspot feature should be unlocked. Also the phone is dual SIM but only one sim works at a time. if you insert two sim cards one of the is disabled automatically when the phone starts.
The second one is a Kyocera Duraforce Pro and i have the same problem with the hotspot as mentioned above. Another problem is the fact that no matter what I do I can not update the software. I have even tried to connect via a VPN from the US.
The third one is a Samsung Galaxy S7 Active but with this one i do not have a hotspot issue. It works perfectly. The problem that i have with this one is that i can not perform software update.
Can anyone provide some info / help? I have tried contacting AT&T, been waiting for a lot of minutes but no one responded.
