Hi. I have a problem. My smartphone M4 does not read the sim.

But when I remove the sim, a message appears indicating that the simcard has been removed.

Was the phone locked to a different carrier? 

[PamaRV]

Yes, but it was already unlocked

@PamaRV 

was the phone working at all ?

Hi @PamaRV, sorry to hear about this.

Has the device read the SIM card fine before and this just started to occurring?

Have you tried with a different SIM card in your device? If you can borrow one from a colleague, family member or a friend, just to test if the SIM card reader is the cause of this or if it is the SIM card that is defect.

Let us know if that helps!
