Get internet access internationally and in very remote areas where no other signal goes. The GPRS PCMCIA card lets you connect to GPRS networks carried over cell phone towers, meaning you can access the internet anywhere you can get cell phone reception.
If you are looking for speed in an urban area, GPRS is definitely not the way to go (since voice takes priority over data on the networks). However, for business travellers the GPRS offers a connectivity option through your service provider that will give you range beyond your normal capabilities. GPRS services are also available throughout Europe and in India, giving you portable internet options that are otherwise unreachable.
