Unlocked iPhones & Metro sims
I need to know if an activated MetroPCS Sim card will work in an unlocked iPhone 4?
iPhone 13, iOS 17
iPhone 4 is 3G, obsolete and no longer supported by most carriers.
You would have to check with Metro PCS to see if they still support this model. (Verizon and AT&T do not, so that might be a clue).
