Hi everyone , i bought a used iPhone 4, he told me it’s factory unlocked , anyway when i insert the sim card it says no service at the top instead of the signal bars . is there a way to fix this ?
clean the sim card and try again, try a different sim card, also check with phone company that imei is not blocked?
try a sim turbo,it costs around $2-$5 only then try to search on the net hot to open it,it works but it’s a lomg process.it’s not a factory unlocked phone.
