I recently removed my SIM and put it back in again. From then on my SIM does SMS and calls only when I turn on LTE in the mobile network section.
Even if internet is off it works with LTE. Why did this happen? What would happen if I put the SIM in another cell phone?
In my cellphone both call and SMS are gray and not active. Even if LTE is on they are off, but I do get SMS/call. What could be the problem?
