E7 1 What should I do if I disconnect after a short message? I will be disconnected from the internet these two days. I'll text you now, and the phone will be disconnected.

Is it Nokia E7 1? If that is WCDMA or GSM network, you are always on 3G network (WCDMA). Now look at your signal. See what I say next.

It depends on your current network status. If you are currently in a 3G network state, the network icon in the upper left corner shows the number 3G, and most areas will not be disconnected when calling or texting.

If the GPRS or EDGE status is a 2G network status and something like E or Y is displayed in the upper left corner, it is a 2G network. At this time, it depends on the region, and most areas will be disconnected.

GPRS technology is divided into class a, class b and class C.

Class A can make phone calls and access GPRS at the same time, similar to ADSL. Surfing the internet and making phone calls do not affect each other.

When Class B is connected to GPRS, sending calls or short messages will temporarily interrupt GPRS, and resume GPRS after communication is completed.

Class c is the oldest. There is basically no such equipment now. You can only do one of the two things, and one must be disconnected, otherwise the other cannot be connected.

It is related to mobile phones, networks and base station equipment, and is generally Class B..
