Apple's mobile phone can't make a call, and others can't call in, only SMS prompts.

There are many reasons why the mobile phone can't be dialed out, such as telephone charges, SIM card problems, software problems and hardware problems.

Many users can't call out their mobile phones, and many problems have been studied. In the end, I often find that my mobile phone has no phone bill. So when you first find this problem, please call 10086 to see if there is any phone bill. Another common problem is the SIM card problem, and there are many phenomena. Sometimes there is something wrong with the SIM card, and he will prompt "SIM card not detected". Sometimes you can't make a phone call without prompting. At this time, you often can't call 10086. At this time, you can take out the SIM card and reinstall it. Sometimes problems can be solved.

But sometimes it's not good to reinstall the SIM card. Maybe your SIM card is broken. You can get a new SIM card in the business hall.

Now is the era of smart phones, sometimes the wrong settings of smart phone system will make you unable to make calls, and the settings of each smart phone are different. If you don't know how to correct the settings, you can reset the network in the mobile phone system or directly restore the system to the factory settings, but you must back up your address book and information before resetting.

The last case is that there is something wrong with your mobile phone hardware, so you'd better find a professional maintenance point to repair it.
