I recently purchased a Galaxy S7 at&t branded phone to use on T-Mobile. It is unlocked, but it is only running 6.0 firmware. The phone isn't receiving any OTA's as promised by tmo. Now the phone is not receiving some texts and I worried about the security of the phone without the latest updates. What can I do???
AT&T delivers OTAs. The rep didn't promise you OTA's in the sense that T-Mobile will send them out. If AT&T has an OTA you'll get them.
You can check here on how to get it
Probably be better to use Samsungs SmartSwitch desktop app and install it from there.
