why is my phone not making calls?

best answer
If you can’t make calls you need to check if your phone is well-connected to network or not. Try these steps. Go to connection setting and select mobile networks. Click on network operator and select automatically. #2 Check if airplane mode is on. You might have accidentally enabled airplane mode. Enabling airplane mode will not let you make or receive any calls. If your phone is not making calls then this could be another reason.
