Is there anyway of unlocking a sim card for a galaxy???? the phones unlocked but the sim card wont register
call customer service. this could be an account problem too or u need a resend to switch
Typically there are really only two reasons that this would happen:
1.) The SIM card is not activated on an account yet : For this call in to technical support and supply them with the number written on the SIM. They should be able to activate for you.
2.) If the SIM is already activated then it may have had a PIN on it that has locked the SIM. If this is the case you'll need to buy another.
Most times the first scenario is the case though.
