If you want to use a 2G card, what is the difference between a 2G network card and a 3G network card

You have too many questions, one by one, one, whether you can use 3G has nothing to do with your **, it has something to do with your mobile phone card and mobile phone. Your mobile phone is Unicom to support 3G,**The card must be Unicom and support 3G,You call customer service to ask if your card can be on 3G.

Second, if your card can use 3G, then directly do a 3G traffic package, and your ** will not change.

3. As long as your card supports 3G network, you can.

Hello, if your SIM card is 2G**, you can use China Unicom's 3G network by ordering a 3G data package. If you want to upgrade to 3G**, you won't be able to use the 2G** you are currently using. If you enable 3G Internet data, you can use it on mobile terminals that support China Unicom's 3G network standard.

You can use the 3G network to access the Internet by activating a 3G data package. Some 2G users of Hebei Unicom can open a 3G provincial traffic package (10-30 yuan optional) through China Unicom's online business hall, mobile phone business hall, 10010 customer service**, SMS, etc., and after successful opening, you can use the 3G network to access the Internet.

Hello, as you said, 2G** Customize a 3G traffic package, you can use the 3G network, and at the same time, the signal will also be enhanced. When the mobile phone surfs the Internet, it will display the symbol of 3G or H, H+.

It's not a 3G card, and you can't get on the 3G network with a 3G phone alone.

No way. Your 2G is Mobile 2G, and 3G is China Unicom 3G

The policies are different in different places, and the manual service of the operator is more accurate.

It's basically the same, faster than not fast depending on the difference in the network.

3G mobile phones are not much different because they use 2G cards.

It's too much faster, it's far from it....

Transmission speed 2G 20-40Kbps The minimum transmission speed of 3G is 384Kbps, first of all: the technology is different, 2G belongs to the second generation of mobile communication technology, 3G belongs to the third generation, 3G because of advanced technology, the speed of Internet access will be faster, the application will be richer, and the experience will be better.

According to the situation you described, if you put the Unicom 2G card on a mobile phone that supports Unicom 3G, you may not be able to use the Unicom 3G network, and the following conditions must be met at the same time: 1. Use Unicom 3G** or the number has opened a 3G traffic package and other services; 2. The mobile terminal supports China Unicom 3G network; 3. If there is a Unicom 3G network coverage in the location, you can use the Unicom 3G network.

H is Unicom 3G, which means that your mobile phone supports this kind of network, but your card is 2G and cannot use the 3G network.

No, you cannot. Only 2G network can be used!

China Unicom 2G card can use 3G network.

Most Unicom 2G** does not support 3G network by default, at this time, you can turn on 3G network permissions by customizing 3G provincial traffic packages.

China Unicom 2G users can apply for 3G provincial traffic packages.

10 yuan package 100m, 20 yuan package 300m, 30 yuan package 500m, 50 yuan package 1GB, 100 yuan package five kinds**, beyond the use of the charge according to the yuan kb.
