I purchased a used Samsung Galaxy S7 on Ebay about 3 years back and have used it on Verizon. Just recently and after asking and being told that all Verizon phones are unlocked after a certain amount of time (maybe 90 days) I switched to AT&T because of coverage issues. Does this mean that it is unlocked? I am thinking of upgrading (2nd hand) to a S10 plus and will probably sell it but want to be honest about being locked or unlocked. FYI: , when I follow the settings, connections, mobile networks ..the Network operators choice is greyed out so I can click it.
I would think if I can use it on Verizon and AT&T, it is unlocked? Thanks for the help!
