I have been using mobile internet for the past 4 months. As long as u can receive mobile phone signal, u can access to internet already. The monthly fee is fixed and unlimited usage.

U may choose from either Celcom,Digi or Maxis. Where is yr exact location?

We are not using phone, the reasons are:
1) Normally phone modem speed is 56k only, and yr phone life span will be shortern.
2) Battery will empty very fast, normally within 2-3 hours. Spoilt easily.

The best solution is using a PCMCIA modem like 3G card that promoted by the operators. It can achieve faster speed, up to 384 kbps in 3G areas.
