Assalam,
I just got an HTC one m7, slightly used. It's from Sprint.
Thing is, when I got it, and inserted my local Sim card it worked well, till the time I updated it. After having updated it once, it simply said: 'Invalid Sim Card: Contact Customer Support'.
I'd like to add that I used a normal warid GSM Sim card. Not an LTE ready one.
It did pick up the sim because it asked for the PIN code whenever I inserted thw Sim inside it. But it wouldn't pick up any signals and there would just be this message, with an icon of course: " Invalid Sim Card: Contact Customer Support".
I updated it again, since updates were available and it was on the outdated jellybean. After about 5 updates, it's now on sense 6.0 and Android Lollipop 5.0.2 but the problem still persists.
Also, when I factory reset it it showed the Sprint set up configuration thingy(Hands Free Activation) and it said it couldn't connect to the network and that I had to change to CDMA to do so. I've tried changing the mobile data type to GSM/UMTS only. And it still would give the error.
Is there an issue with the device having not been fully unlocked?
Or could it be an issue with my Sim card? I did try a friends micro Sim card (U-Fone) and it would still display the same error.
Any help regarding this would be most useful.
Regards,
Skywalker
