Frequently Asked Questions

Is this reader compatible with the iPhone 12 Pro?

No. The dimensions of the internal structure and the position of the connectors differ, this part being exclusive to the iPhone 12 Pro Max.

Is the "No SIM" message always resolved with this replacement?

It is resolved when the defect is physical in the pins or module connector. If the baseband circuit or main board is damaged, the symptom may persist.
