I have had my M8 for a month.
Two days ago, I discovered in the morning that I could not make any calls, and that no one could call me. SMS did not work too.
Disabled 4G, and was back again. So I guessed it was just my phone company having problems with their 4G service, since 3G worked fine.
Tried several timnes after that to enable 4G, but everytime I got no signal bar.
This morning it got worse:
Now 2G and 3G doesn work either.
The strange thing about this "new" status, is that I have full signal. Data traffic works. So internet stuff works fine, but SMS and Voice does not work.
Called my phone company, and they checked their service in the area pluss they also checked my acount, without finding any errors.
They are saying that the error has to be on my phone.
I have booted the phone, reinstalled the SIM, but still the same status.
I also shoud mention that I am running the latest stock SW rom,
I am starting to wounder if I have a HW error on my phone?
Any sugestions on how to fix this?
