5. If the traffic usage reaches the maximum value in the current month, the network will be automatically closed, it is recommended that you pay attention to our SMS reminder or inquire about the **product description.

If there is no signal on the mobile phone, the first point may be that the signal on your side is relatively weak, if there is no signal all the time, it means that there is something wrong with your mobile phone, haha!! First of all, you take out the mobile phone card, wipe it with alcohol, and install it, if it still doesn't work, you may have to go to KF, one word "repair".

Generally, there is no network may be a problem with the RF of your mobile phone, and it is very cheap to repair it in a small place, and 50 yuan will definitely get it.

It can be turned off and back on. If it still doesn't work, take out the ** card and try to turn it on.

Also, there may be problems with your ** company network, which will cause this.

It's just that there is no signal, if everyone has a signal, it means that your antenna (internal and external) has a problem and needs to be repaired. I only had this question a little time ago.

1 Regional Signal.

2. The phone has airplane mode turned on.

3. There are people in the vicinity who use the setting of shielding signals.

4 phones are broken.

Did you not put the SIM card? Either that, you don't have a signal in your area (e.g. in a subway tunnel :)).

It may be that the card has been canceled, and if you didn't use your own province when you applied for the card, then it is possible.

Haha,It's not a 3G mobile phone will also have this phenomenon.,It's just no signal.,Big brother,Xixi.。

There is a problem with the phone, the signal amplifier in the phone is broken, or the contact is poor.

Try to change the card, if it's not good. It is the hardware failure of the mobile phone, which is generally the failure of the mobile phone amplifier.

You don't have money on your phone???

I also have this problem with my phone, which is a problem with the antenna. You can take it and fix it.

Are you a straight-pull phone? The problem must be on the antenna!! Let's fix it!!
