Is there a way to unlock my HTC Android phone? I did not follow through with the transfer to Ting, and they have already processed my phone by dropping me as a customer. A family member recently purchased a new SIM card for my phone. But once we installed the SIM card, the message "Invalid Card: Please contact customer care" appears when it turns on. The new SIM card company said I need to get the phone unlocked so it can be used again. Please help.
