My sister has offered to put me on her family plan with AT&T for $10 a month. She says I can use my Sprint phone if I know my unlock code. What is that and where do I find it?
Thank you so much.
Your unlock code is usually all 0's, or the last four of your current phone number.
However, good luck doing that.
Sprint phones (CDMA) are not compatible with AT&T service (GSM).
