Vertu's cell phone can't make a call. If you have been working very well and suddenly can't make a phone call, it should be a hardware problem, and it should be a transmission circuit problem (mostly a power amplifier problem). Because the mobile phone can receive signals, but the mobile phone has not transmitted signals to the base station for a long time, the base station will think that your mobile phone is turned off.

Just like when your mobile phone is turned on, you can take out the battery directly without turning it off. When you use another phone to call your mobile phone, you will say that you can't connect temporarily at first, and then call again and say that your mobile phone is turned off.
