What are the advantages of connecting my PC to the Internet via my mobile phone?
There are several advantages including no need for a separate subscription, freedom from carrying around a 3G dongle. In many cases this may also be a way of saving money since connecting your PC to the Internet via a Bluetooth connection doesn’t require purchase of additional software. And, this gives you the ability to connect even in rural areas where 3G coverage, which is required for the typical 3G dongle, is necessary.
