I bought one of these off Woot last year, thought I’d use it but never really did… it’s unlocked too… just last week I tried to upgrade to Android 13 as my work won’t allow anything less… come to find out no upgrade available, nor is this model even supported anymore… you hit a wall at Android 12 and then it’s kaput in terms of software upgrades, bug fixes, etc… frustrating that tech keeps dying to force us to keep buying newer tech…
I have one of these and it is locked to AT&T I have been trying really hard to get it unlocked even use an At&T sim for several months adn still no luck unlocking it to use my T-Mobile sim. It is a beautiful device but it sits unused with my collection of other older phones. Be careful buying this if unlocking is your goal.
