Is the signal of mobile phone and the signal of Internet the same network?

You can say yes or no, it is said that the signal of Internet access (GPRS EDGE) is based on the signal of telephone call (GSM), but the two cannot coexist at the same time. When a phone call or short message (GSM) comes, the signal of Internet access (GPRS EDGE) is disconnected.
