Dialup connection requires only telephone line so you can connect to internet even you are in any rural areas. For connecting to internet using your dialup you need to call to your ISP Provider, this is called handshaking mode. Once connection established you can start surfing internet. The handshaking mode is a source of frustration because many dialup users dial same number than your chance of getting connection will be less or it will take time to connect. Dialup connection is the cheapest solution for your internet need but your telephone line gets engaged when you are using your dialup connection. So, it will cost you higher because call duration incurs cost.
