Does it make sense to change to a 4G card without turning on the traffic?

No, you don't have any data, and 4G is useless.

If you want to use the China Unicom 4G network, you need to meet the following conditions:

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.

Hello, the general traffic in the 4G traffic** is the traffic that can be used on the 234G network, and this traffic can be used on 234G cards.

In addition, some** will give away some additional 4G dedicated traffic, this part of the traffic can only be used for 4G, 23G can not be used.

There will be no 4G data charges alone.

Hello, if you are a Beijing Mobile customer, after applying for the Global Pass**, the traffic in ** can be used under the 2G, 3G, and 4G networks, and then the excess fee will be charged. Please refer to it.

Yes, you will be charged based on the amount of data.

If you don't change it, the tariff for deducting traffic on 4G will definitely be more expensive than **.

You have a global pass** for a 4G card, but you haven't changed **, you can't get on a 4G mobile phone with a 4G phone, and you shouldn't have opened 4G**.

Grass: I didn't open 4G**Ah, it's a 4G card, you can use 4G, and I asked for a manual service today**, that kind of general data traffic package, 2 3, 4G sharing.

One by one, it's funny, you have to ask about the local move. It's not the same in different places.

Zhejiang's can, it seems that you have to change 4G** to use 4G traffic, and you don't want to change**.

Based on your description, we recommend that you try the following steps:

1. Check whether the SIM card is enabled for GPRS Internet service or temporarily closed.

To use the mobile phone data Internet function, the ** card needs to activate the data data Internet service. You can contact the local network provider of **card** to open the data traffic Internet service.

2. Check whether the "Mobile Data" switch is turned on.

Slide your finger down on the top curtain of the screen, slide the shortcut bar to the left, and turn the "Mobile Data" dot green.

3. Reset the Internet access parameters.

In standby mode, select the standby screen - Applications - More settings - Mobile network - tap the name of the access point - Menu - Reset to silent settings - After the settings are completed, restart the hand to surf the Internet.

Note: If you are using a mobile card that does not support NET services, you can select a WAP access point by pressing Qingshu.

4. Please try to change to another ** card.

Unicom 4G** is not required to be used under the 4G network balance and high network, Unicom 4G card in the absence of Unicom 4G network or mobile phones do not support Unicom 4G network, can be backward compatible with the use of Unicom 3G 2G network.
