Can you tell me what a locked phone is versus an unlocked phone? What happens if somebody buys a locked phone? What functionalities would be limited?
And why do people sell locked phones? How did they become locked? How can phones be unlocked?
Thank you. On swappa they do not specify whether a phone is locked or unlocked* but they do provide a warning that if a phone is locked it cannot be unlocked. ๐ค I'm a bit leery of this. What do you suppose that's all about?
But when I browse their "unlocked" category first they say it can be activated by any carrier, then read further down it says it can only be activated by three carriers: "unlocked" (is that even the name of a carrier?) or "cricket" or some other carrier I've never heard of. If I buy a phone from their "unlocked" category but it says it can only be unlocked by cricket or whatever, could T-Mobile not unlock it for me? I am a T-Mobile customer.
