Do you want to turn off the E in the upper left corner of Apple 4? Is there no traffic charge?

No, I don't say that because the mobile phone supports Unicom's 3G card, so there are ** I'll talk about the problem of mobile, first of all, the mobile phone does not support mobile 3G service, because the mobile phone does not have a mobile band, so now the mobile card is used to access the Internet2G business, that is, GPRS traffic Internet, when you turn on wifi, and the cellular is not turned off When you use the Internet function, billing will be generated, why? Because the wifi of the 4S mobile phone and the 3G option on the cellular sea cell work together, although the default is to use wifi to surf the Internet, but sometimes your wifi may not have a good signal and there is a breakpoint, 3G service will be assisted** If 3G is also card, then the cellular will be assisted**.

To put it simply, if you use a mobile card, when the wifi signal is not good, the cellular will begin to go traffic assistance** (because the mobile does not have 3G service), so it will generate GPRS traffic fees (that is, the cost of your words), so if you use a mobile card, you have to manually turn off the cellular every time you turn on the wifi, and you need to use the cellular when you manually turn it on, after all, there is no 3G service, all the GPRS is gone, if you have been living in the city, it is more practical to choose Unicom's 3G card, if it is mobile, it is fine The signal is better than Unicom (except for the city, the basic coverage is the same, only outside the city), I use a mobile card, nothing inconvenient.

This is something I've done on a similar issue with someone else.

No need to turn off, no deduction is made through this access network!

That's the Edge network.

DU

The flag (that is, the network) network speed is faster than that of ordinary GPRS, and if it is turned off, the dao is selected in the network back settings.

Answer: Ze "Turn off the cellular network" itself is free of data, but the iPhone has a lot of background programs that will update by itself and secretly take away the traffic It is recommended to turn it off when not in use (CCTV once reported that the iPhone app secretly took the traffic No way.) ）

It's the network, you.

The system used is a CMNet access point! In Settings, General, Cellular Data, and then turn off the network can be turned off. Only software with push messages or prompts such as QQ that you open the notification background will burn traffic, so turn off the network when you don't use it!

iPhone traffic is also amazing, mobile phone typing is not easy, give points.

The sign of the Edge network... That just means you're edge. If it's 3G, 3G will be displayed. The traffic has nothing to do with that flag anymore

Yes, it's best to turn it off if you're not online, because there are a lot of programs that run automatically in the background, remember! Open it when you're ready.

Yes, however, some software will take the traffic when opened, and it will not be displayed.

Yes, that's a sign of your internet connection. You can turn it off

If e is displayed, it means that you have turned on the Internet function, and if E is turned off, you will not be able to access the Internet.

Hello, E does not mean error here, but represents Edge (mobile calls it egprs), which is a type of GPRS. E indicates that there is an Edge GPRS signal and you can use GPRS to access the Internet. That is to say, it has been networked, E is the mobile 2G network, and the mobile card 2G network is E.

The domestic signal degree is g e 3g h

E is the edge of China Mobile, as long as the edge is not moving, it will not go traffic.

If you feel that the traffic is old, you can ban some background pushes (some seem to have to be jailbroken to prohibit it).

There will be no data deduction! Because you visit the web page, there will be byte calculation! You didn't hit the page! There will be no bytes! There will be no deduction at all! It's like you're hitting **! The other party didn't connect! Of course, it doesn't cost anything!

If the e-side mountain shows a chrysanthemum wreath turning, there is traffic, otherwise it's fine.

Usually when you don't go online, you turn off 3G and wifi. I'm going to get on. Whatever you need to use, you can open it. This is the safest.

If you turn on 3G, there will always be an icon like that, in fact, if you don't update the software, you won't take much traffic, if you're afraid of traffic, then turn off the 3G in the settings when you're not on the Internet, and turn it on when you use it.

It's cellular data, just go to the general network, then turn it off, and the traffic will be deducted.

Yes, however, some software will take the traffic when opened, and it will not be displayed.

Remember.

Jailbreak it.,After jailbreaking, the traffic of some background software is not easy to control.,It's best not to jailbreak.,And then turn off the cellular data network and it's fine.。

Please double-click the "home" button to enter the background and close all background programs, otherwise the programs will still be in the idle state.

No, it's an e-network. There is also a g-net.

If you don't go online, you won't have it.

Kiss! Even iphone4s hey I don't know if the steps are different Click on the settings to enter the general "click on the network" (you will see the cellular data) click on it, (when you see the blue e, the cellular data is blue, when you don't see the blue e, it is no color drops).

And don't just enable the 3G network, it may reduce the battery life!!

There is also data roaming, which will deduct roaming charges

Hope it helps you).

Settings - General - Cellular data in the network is turned off.
