Some people say that mobile does not have a 3G network, only 2G, and some people say that there is 3

Mobile has 3G, TDSCDMA, China's own, so it is pushed by the largest mobile operator, but from the current point of view, China's 3G standard has failed, and the share of mobile has also declined a lot, and mobile is now stepping up the layout of 4G, TD-LTE, hoping to win back from 4G, and so far the evaluation of mobile 4G is not bad. The 3G of China Unicom and China Telecom are both European and American 3G standards, which are better than those of mobile.

Yes It's a fake 3G in reality, but it's actually 2 or several. Unicom is the real one! Speed can be experienced!

The kind of tariff that moves is even more expensive, and a group of people can't afford to spend it.

Now there are three main types of 3G systems: TD-SCDMA, WCDMA, CDMA2000The first one is the mobile 3G system, and the brand they give is G3

The second is Unicom's 3G standard, which is also an international standard, so generally the mobile phone you buy supports this 3G standard, so buying a Unicom 3G card can generally be supported by mobile phones now. The third is telecommunications.

Yes, I'm using a mobile 3G, and it's a smartphone. It's very easy to use, the network speed is much faster than 2G, but the data consumption is fast.

Support mobile, is there still anyone using Unicom now?!

Now China Mobile Unicom Telecom has its own 3G network, I have used all three, I personally think that Unicom 3G is the best, Telecom Tianyi is second, and Mobile G3 is the worst.

The mobile 3G is independently developed by TD-SCDMA China, which is not very good.

At present, only China Unicom is a pure 3G technology WCDMA

If you are using a Huawei phone.

There are many reasons why the mobile phone does not have a 4G signal and only has a 3G signal, please follow the following methods to troubleshoot:

1.If you have a dual SIM card and the primary card does not have a 4G signal, check the supplementary card.

Whether or not you are receiving MMS messages.

If you encounter a problem when the supplementary card receives SMS and MMS, the main card will display 3G:

1) You can enter the information interface, click on three dots or four dots, enter More > Settings > Advanced or Settings > Advanced, and then set the automatic excitation in the **MMS to Off.

2) If your mobile phone supports dual VoLTE dual pass, it is recommended that you enable the Dual SIM VoLTE function: in the VoLTE network coverage area, when the dual HD icon is displayed in the status bar of the mobile phone, two cards can work at the same time.

2.Please make sure the 4G switch is enabled.

1) When installing a single SIM: Please swipe down from the top of the phone screen, open the shortcut menu, press and hold the mobile data icon, enter the settings interface, turn on Enable 4G or select 4G 3G 2G in network mode to automatically select.

3.Please move your current location.

You can check with your local carrier for network coverage, or observe that the same carrier SIM card is used nearby.

If there is no 4G network as well.

Generally, the local operator's 4G network coverage is poor and unstable, so it is recommended that you try it after moving to other places.

4.Please reset the APN

Incorrect APN settings will affect the normal use of the network.

It is recommended that you open Settings, enter APN in the search bar at the top, click Access Point Name (APN) to jump to the mobile data settings interface, click the Access Point Name (APN) again, then click the three dots in the upper right corner, and select Reset to Default Settings.

5.Please restart your phone or switch it on and off the Flying Mode.

The special configuration of some networks may cause your phone to be unable to return to the 4G network for a short period of time, but it can be restored after restarting the phone or turning on the airplane mode.

6.Please reset your network settings.

7.Please remove the SIM card.

1) If your mobile phone card is a manually cut card, it is possible that the signal reading may be affected due to non-standard shape and poor contact, so it is recommended that you bring your personal ID card.

Go to the operator's business office to apply for a standard mobile phone card.

2) Dirty or oxidized SIM cards will also affect the reading of signals, so it is recommended that you keep the SIM card clean.

8.It is recommended to update to the latest system version in a timely manner.

If your phone is not up to date, back up your data in advance.

If your phone still only has a 3G signal, please contact Huawei Consumer Service** (950800), back up your data in advance (third-party apps such as QQ and WeChat need to be backed up separately), and bring your purchase voucher to a nearby Huawei Customer Service Center for testing.

Make an appointment for service. Boarding service.

Repair spare parts** inquiry.

The phone doesn't have a set signal, only a 3G signal, which is also due to your setup problem. So sometimes we can switch our mobile phone when you turn on the mobile phone signal, and switch it to 4G priority. If not, you can turn it off later and restart it.

Maybe your mobile phone is a 4G version, and your location 4G signal is poor, for example, the remote rural signal is much worse than the city, if you have the conditions, don't live in a remote rural area, if you like the countryside, you can live in a county-level city not too far from the city, the 4G signal will be a little better, if not, that is, your 4G version of the mobile phone is very old, the performance is relatively poor, the ability to receive the 4G mobile communication network is also relatively poor, and you can also change to a new mobile phone if you have the conditions, The received 4G signal is better, or it may be that your mobile network mode is set incorrectly, you can open the phone's settings icon, and then turn on 4G priority (if possible) in Wireless and Network

Maybe your phone is in arrears, or your traffic is overloaded, right?

At present, in China, only China Mobile has obtained a 4G license and operates in the 4G format of TD-LTE

They refer to the mobile phone signal, 4G is faster and smoother than 3G! It's true that only mobile now has 4G

If your mobile phone cannot access the Internet normally, please check the following conditions:

1. After upgrading to 4G 5G**, if you don't restart the phone, you will not be able to use the Internet function normally;

2. Confirm whether there is a network, it is recommended that you can use it in a place with a strong signal;

3. Check whether there is still a phone bill in the account, if the balance is insufficient, you need to recharge before you can use it;

4. After 3-5 minutes of power off, restart the phone and try again;

5. Check whether the USIM card is inserted, if it has been inserted but still cannot be used, it is recommended that you go to the business hall to check whether the USIM card is faulty, or replace the card for testing;

6. If the traffic used in the month reaches the maximum value, the network will be automatically closed, Xianyuan recommends that you pay attention to our SMS reminder or inquire **product description.
