I can't make a phone call on my mobile phone, but I can still make a phone call in Tianjin in the morning. Fly to Shenzhen, and you can't make a phone call when you arrive.

Call the manual service desk at 10086.

Hahaha, then you set-network settings-

Wanlddasd Network Selection-Change to Automatic. Brother, can you give points? //If you still don't believe me, change your mobile phone and there is still a problem. You can give this to anyone. No problem, you can give it to me.

Ok, let's look at the call settings-call ban-is it forbidden to pull-? Click to cancel the restriction.

No more line switching-Line 2 attempts.

Turn it off. Pull out the card, plug it in, and then turn it on.

Have you tried everything? Have you tried changing your cell phone?

Copy something for you:

I am lucky to meet this situation today, so let me make a phone call when I need it.

It turns out that I am 1 line and call settings-local number (hidden number)

Finally, I changed the call settings-local phone number to the system default. After changing the line to 1 (I originally changed the sum of the lines of 1 to 2, not bad! )

A friend's mobile phone Tianyu originally used Unicom's card, so it's no problem to make a call. Later, I changed it to a mobile card, so I can answer the phone instead of making a phone call. As soon as you call, you will be prompted to confirm the network service, but it is no problem to call the service desk! How strange!

Think about it, Unicom was ok before, which means there is nothing wrong with the mobile phone itself. There must be something wrong with the settings. The network settings have been changed several times, and the effect is still the same!

Finally, I can't. I have to restore the factory settings. Oh, my God! Need a password!

What is Tianyu's password? I didn't bring the manual, so I went on with Baidu and finally found it after looking for it for a long time!

Domestic products generally default to11220000000123412345123456 and so on.

Enter the password 1 122 to confirm the resumption of the call. It's through! All right! Problem solved!

Ha ha. . . Baidu is the best teacher! What don't you understand? Baidu all the way!

If I don't give you points, I'll hit someone. That only means you are stupid.
