Hi there, Nowadays many people have faced this type of problem, some are with their phone and others are with modems. My little brother was stuck with their phone, Actually when he changed the SIM network his phone go locked. He searched on Google and found the many methods. Then I suggest him to use unlock codes for unlocking the phone. He sent the IMEI number of the phone with country and operator to the unlocking company. After using unlock codes, He unlocked his phone within a few seconds.
