The Sim Card Has Locked Please Power Cycle Boost Mobile. Enter the unlock key on your mobile phone. The Carrier Locked line says either No SIM restrictions if the PHONE is unlocked or SIM Locked if the PHONE is locked to a carrier.
Some people like to use the sim card security feature known as a SIM PIN. If it is a Network Carrier SIM issue -- If you see invalid SIM or no SIM on your iPhone or iPad. Please power cycle the device and if the problem persists contact customer service when swapping a SIM card from one phone into another.
I keep getting a message popping up saying The sim has locked.
Apparently you get 10 chances at unlocking before you brick you phone. Please power cycle the device If problem persists contact Customer Service followed minutes by Invalid SIM. FINALLY was able to have them activate an unlocked iPhone 6s so that I could use it on the Sprint network. Sim is locked please cycle power Tech Support.
