Hi, I live in the US and wanted to know if I bought the lumia 620 off of ebay or something and used it here would it work on ATT?
So does it work with 3g and HSPA plus or just HSPA?
Most of the E-bay purchase phone comes with locked condition,So before use your AT&T service ,Make sure your new phone is unlocked one.If it's locked by particular network means,you will need to unlock your phone.For unlocking you can approach your service provider or else try to buy an unlocking service from any one of the online unlocking service provider like SimpleUnlocking.com I hope it will be very useful to you.
