If you cannot use the 4G network of China Unicom, we recommend that you use the following conditions to troubleshoot the 4G network:

1] Use China Unicom 4G** or ** have opened 4G network function;

2] The mobile terminal supports China Unicom 4G network;

3] The location has a 4G network covering China Unicom;

4] The number card is a USIM card.

You can check whether the above conditions are met, and you can only use the 4G network after you meet them, if you still can't use the 4G network after eliminating them, it is recommended to consult the local Unicom customer service to check whether the base station facilities are faulty.

1. The 4G network is not opened.

2. The area is not in the 4G signal coverage.

3. Mobile phone problems.

Solution: 1. Consult with the operator ** whether your mobile phone card has opened the 4G network and whether the 4G service has been opened.

2. At present, the 4G network has covered most of the first, second and third-tier cities, and the signal coverage in many places is not very comprehensive, and the signal coverage is not very strong, and the parking lot or underground shopping mall will not be covered by the 4G signal. You can change the phone to detect whether it is a network coverage problem.

3. There is also a possibility of problems with the mobile phone itself, such as mobile phone system problems caused by improper jailbreak or improper flashing, but it is rare. You can send your iPhone 6 to the official after-sales service for overhaul.

If you can't solve the problem, please call the customer service of your telecom operator and ask whether to open 4G or whether the signal coverage is a problem.

Whatever the reason, you turn on airplane mode first, then turn it off and it changes back!

Network issues. It shouldn't have anything to do with the phone.

First of all, the Apple Six is an available phone. Then the original display of four G, now the display of three G, may be your mobile phone speed is limited. You may have recently used traffic in your senior year as a result of the signal reception changing from a four-G network to a three-G network.

Because the traffic in the current mobile phone card is generally unlimited, but there is a network speed limit, for example, most of the current networks are 4 billion networks, and a few of them become five-G networks and three-G networks. Then under the premise of limiting traffic on the four-G network, once the maximum amount of traffic is exceeded, your network speed will cool down, three G, and you will also display three G. It is also possible that the signal near you is relatively weak, so it is reduced from 5G to 3G.

If the signal is less than 3G, there will be 2G or H network, which is caused by the poor signal in a confined space or around.

I'm the same as you, it's been three days, and the signal is turned on, the SIM card is turned off, and it doesn't matter if you put it in again, I've tried it several times, and I'm sure that 4G has been turned on Never done like this before**It's also 4G, and the traffic is enough Speechless, I hit 10000 and there was no result.

Try opening Settings - Cellular - Cellular Data Options - Enable 4G - Voice & Data (I chose it this way). Because my phone has been like this for a long time, and today it is all suddenly like this!

Mine is useless at all, it's still 3G in Xi'an City

Hello, there are 2 reasons: one is that the 4G signal on your side is not good. The second reason is that you have a 3G network set up.

Could it be that you don't have a 4G signal in your current environment?
