>Why is mobile used for important things

In the developing world, this is often the only link people have to the Internet at large. I worked in a company with primarily Nigerians and one of the biggest developments in recent years are payment systems built over mobile networks.

Since most other countries don't bundle the phone with a contract and SIM-lock them, SIM-swapping is a very reasonable way to pay-as-you-go while hopping between mobile networks and regions.
