Newmind No 2 mobile mini phone can t be turned on, ask for a black hearted merchant, give one.

What should I do if my phone can't access the mobile network? Check the mobile settings to see if the mobile data is turned on.

Let's restore the mobile network under the factory settings.

If you still can't connect, you need to determine if it's a problem with your phone or a card.

First, shut down and restart.

Second, shut it down, take the card out, and reinstall it.

Third, call **10086 directly or go to the local mobile company.

Shutdown and restart, remember, is a shutdown and then restart, not a direct restart. If it doesn't work after trying a few times, you can go to the place where the phone is repaired to see what's going on.

Check whether the phone bill is in arrears, if not, the mobile phone can ask 10086

If your phone can't access the internet with mobile data, we recommend that you try:

1.Swipe down the top curtain of the screen to turn on mobile data. The SIM card needs to be activated for Internet service.

3.Try a different SIM card or a different time period to troubleshoot network issues.

4.Upgrade your phone to the latest version.

5.If it doesn't work, please back up the data in your phone and restore the machine to factory settings.

If the problem persists, please bring the purchase receipt, repair card and machine to the Samsung service center for inspection.

Go to Settings - Wireless & Networks - Mobile Networks - Access Point Name - Press the Menu Key - Reset to Default Settings. Then China Unicom access point selects 3GNET mobile CMNET to see if it can access the Internet, and it can't be the problem of the ROM package Generally, it is unlikely that the ROM will have a problem, it may be that your network settings are wrong.

Check to see if you are in arrears, then turn the card off and then turn it on, and then restart the phone. If it doesn't work, double check if you owe money.

Check whether there is a mobile phone card, if there is a signal, you can check whether there is a signal under it, if you have it, you can check whether there is any arrears in the phone bill, and if you have it, consider the problem of the machine itself.

The problem description is not specific enough, is it newly bought, and it can't be accessed when you press the card, or was it okay before, but not now?

If it's the former, please see if the phone is a customized machine, or is it a full Netcom?

If it's the latter, it's most likely that you're in arrears, or the system is chaotic, try restarting your phone. Or your subscription network is 4G, and your signal is not good at present, and the display is 3G or 2G, you can look at the signal to confirm whether the signal is not good.

Those so-called what cards ran away, and other messy setting classes, the probability is a bit low.

If you can't access the Internet with data on your mobile phone, we recommend that you follow the steps below:

1. Contact the operator to confirm that the SIM card of the mobile phone has opened the Internet function or whether there is any arrears;

2. Make sure the data network switch is turned on, and try to see if you can access the Internet after restarting the phone;

3. Check the signal icon of the status bar at the top of the mobile phone screen, whether the signal is weak, the signal is unstable or there is no signal, if the signal in the local environment is poor, try to change to a different place;

5. Replace the SIM card to confirm whether it is a SIM card or has poor contact with the card slot, if you still can't use the data network to access the Internet, please bring the purchase invoice, warranty card and mobile phone to the nearest OPPO customer service center for testing and processing.

Just find and restore the network settings by doing a factory reset.

There may be many reasons, it is recommended.

Turn the network off and on.

Turn the computer off and on again, and turn on the network.

If none of the above can be solved, try resetting the network settings, usually here will do.

There are also some places where there is no mobile information (this can generally be ruled out and found by yourself).

Try to take off the mobile phone card and reinstall it, sometimes the mobile phone card is loose.

Restart your phone.

Turn on airplane mode and turn off airplane mode after two minutes!

When Samsung mobile phones encounter this situation, it is generally recommended to perform the following steps to troubleshoot and deal with it:

1.Try to replug the SIM card.

2.Try to change the geolocation.

3.Try to change another SIM card.

4.Back up your data (contacts, messages, **, etc.), factory reset attempt.

If the problem persists, it is recommended that you bring your mobile phone, purchase invoice, and repair card to the local after-sales service center for testing.

Take your mobile phone and ID card to the mobile business hall, the staff can help you with real-name authentication, it's easy, I didn't use my ID card to do it before, and I only recently bound my ID card.

Take the ID card bound to the number and my ID card to the business hall to handle it.

Now the real name needs to provide the ID cards of both parties, in your case, go to the business hall to explain, see if you can change it, I hope it can help you!

The phone card is not in it, or it is broken.

But if you want to use the 3G network, you must buy a 3G mobile phone, the dual-mode mobile phone is an ordinary network, and the Internet is not very fast!!

Let me tell you, you can only use the card of China Telecom to buy a mobile phone, and you can use China Unicom if you want to buy a mobile phone. The mobile signal is good, much better than telecommunications.

ZTE K70, Samsung W599, and some revision machines can be taken a look at, there are C+G machines.

It is possible that you are not in the service area. Or if it's connected, the signal is not good. If you want to say that it is a problem with your mobile phone, it can only be that your mobile phone itself has a bad signal.

You can try a different phone, if there is still no signal frequently, it is a problem with the card. If that's normal, it's a problem with your phone!

I also have such a phenomenon, it is a card problem, because I took a friend's mobile card and put it on my mobile phone, there is no problem, I changed the card.

Go to a place with a stronger signal and a larger amount of ** to try, like an elevator, basement, whose signal will not be good, if it still doesn't work, you should change your mobile phone.

Try it near a cell tower, and if it doesn't work, it's a problem with your phone.

The card is not cut, if it has been cut, please replace the new card after testing;

If it has not been cut, please look at the metal contact points for serious wear or debris, if not, please go to the mobile business hall to check whether there is a problem with the chip;

It is best to go to the business hall to which the brand belongs to check whether there is a problem with the internal program or card slot;

Through the above tests, I believe that the landlord should be able to find out the problem.

There are only two situations when the phone has no signal:

1. Network problems or network inability to cover. When the network coverage is not good, it is generally located in mountainous areas, basements, elevators, and when there is shielding or signal interference, there will be no signal or very weak appearance.

In the process of debugging, optimization and maintenance, the network may also cause signal instability, and the general network will return to normal, and the mobile phone signal will return to normal.

2. Problems with the mobile phone itself. There may be a problem with your phone's receiver. You need to go to the repair point to have a look. Of course, the factor of SIM card corruption cannot be ruled out.

It may be due to the following reasons: 1. In the region, the network has been adjusting for a period of time.

2. Maybe there is a problem with the receiver of the mobile phone, sometimes good and sometimes bad.
