Hello Faye. In order to give you a few recommendations, we need to have a full IMEI Report of your iPhone. Do you have one? Or, do you know which network is locking it, which network blacklisted it, its iCloud status, contract/financial status, and IMEI/Serial replacement status? If yes, please send everything to us to evaluate it and give you a suggestion. If no, you can use our iPhone IMEI Unlock Check service, and we will take care of it!
