      1G was only for voice. 2G was in the first phase also only for voice, SMS was introduced by "mistake", they didn't thought that it would be "seller" point. Roaming was possible in 1G roaming as well. 1G using low frequencies like 450 MHz could cover large distance, but the voice wavelength in the distance was weaker and weaker with greater noise, so it was very hard to understand something in it.
