i unlocked/jailbroke it successfully and inserted my tmob. sim but it wouldn’t read it. i eventually went to a phone repair store and was told that the phone wouldn’t read any sim. how do i fix this myself?
try resetting the network settings settings>general>reset>reset network settings (OS4.3) settings>general>network>cellular data network>reset settings (OS3.1) HIH
try putting tape on back side of sims so it pushes dron harder on pickups ..
