3G is about to be used, can you still buy a 2G mobile phone now? How long will 2G last?

Now 3G mobile phones, in terms of network standards, are backward compatible, that is to say, 3G mobile phones support 2G networks. But if you use a 2G card on a 3G phone, then you will not be able to experience the speed and convenience of 3G network. Therefore, I recommend:

1. Try to use the mobile phone of the same network operator, which can ensure your convenience in use. For example, if you are using a mobile card now, then when you change your mobile phone, try to choose a mobile phone that supports the TD network, so that you can directly use the mobile 3G network. The same is true for China Unicom and China Telecom.

2. If you don't care about network speed and convenience, then you don't need to worry about network standards and operators. Because all 3G phones support 2G cards.

Unicom 3G is also available for mobile, card....It's just that it only has a 2g effect.

If you are not happy with the Internet speed, just care about 3G Unicom! It's really much faster.........

I also bought a mobile phone that supports 3G, Nokia C6-01 to use a 2G card, because I don't want to change the number, but I like its features and style, especially its screen.

Today's 3G mobile phones are dual-mode, 2G can use 3G cards, 3G cards, or 2G mobile phone network operators will automatically default to your network!

But if you want to use a 3G network, you have to use a 3G mobile phone and a 3G card!

No, it doesn't. It's fast. The order is, 3G is faster.

It doesn't matter, it doesn't affect the use.

5G card has 6G mobile phone speed is mobile phone has 5G card speed is 4000kb. The network card connected to the network card 3200M must have a 320G network cable, and the mobile phone must come with 32G running storage in order to play it.

The mobile phone is 3G, and suddenly it can only use the 2G network. There are several possibilities:

If there is no 3G signal in the current location of the mobile phone, the mobile phone will automatically switch to the 2G network. At present, the 2G network is the most mature. The most base stations and the strongest coverage.

The local base station is repaired or upgraded, and the equipment needs to be maintained and maintained. If there is no signal for a while, it is also normal.

There are too many 3G signals nearby, and the 3G network coverage is not very good. If there are more people using it, the system will automatically screen and accept good signals.

If there is a problem with the mobile phone, this can be verified by yourself, and it can be detected in the place where the 3G signal is OK. If other mobile phones have signals, but this mobile phone does not have them, consider going to the mobile phone after-sales inspection.

Mine too! It's time to change to a 4G card.

If you are unable to use the 4G network, we recommend that you do the following:

1.Check whether the SIM card supports 4G services.

2.Whether to select 4G network mode: Settings - Connection - Mobile Network - Network Mode: SIM1, SIM2, 4G, 3G, 2G (Auto Connect) or 3G 2G (Auto Connect).

Note: When two cards are inserted into China Unicom mobile card: 3G or 4G network cannot be used at the same time, if one card is set to 4G 3G 2G (auto-connection) or 3G 2G (auto-connection), then the other card will automatically become 2G network only.

3.Check if your area is covered by 4G networks and try to move to another location.

4.Shut down, restart, or try to change the card.

5.If it doesn't work, it is recommended to back up the data in your phone (contacts, messages, **, etc.) and try to restore factory settings;

If the problem still exists, please bring the purchase invoice, repair card and machine to the service center, and the professional after-sales engineer will help test it.

It depends on what phone you're using. Divided into mobile 3G, China Unicom 3G Telecom 3G corresponding to the mobile phone to put the corresponding card, it is 3G, otherwise it is 2GExcept for 4G mobile phones! Hope it helps. Hope to adopt!

If the phone is marked with E, it is 2G. If the target is 3G, it is 3G!

What phone are you using now....
