So, like many, I received the Gear S2 when I got my Galaxy S7 a few months ago. I'm just now getting around to trying to sell it. One person asked if it would work on TMobile. Is the Gear S2 locked to Verizon?
The gear s2 3g uses an E-Sim and T-Mobile should be able to activate it on their network. Was it ever activated on Verizon? If so, I am not sure if it lock the sim or not. It should not but you may want to check with a T-Mobile rep.
