Invalid card, please contact customer care
I have ordered my HTC ONE e8 form China. I was using it in Poland for one year. Everything was fine.
I came to USA and I was still using my polish sim-card and service was delivered by my polish operator. I was using the global mode and I didn't have any limitations with communication, everything was fine.
I have bought a Lycamobile sim card. Once I've put it into my phone I got the error message
please contact customers care"
The new sim card is working fine in my US friend's device.
My firend's sim card gives me the same error message.
My old card is still working fine inside my phone.
What is the problem with my phone? How can I solve it?
Es esta una buena pregunta?
