If you take your laptop on holiday with you to Thailand, and need internet access, its simple!
Get either a DTAC or AIS SIM card for your mobile phone.
Call up the call centre.
Ask for GPRS/EDGE unlimited 7 day.
They will charge you about 5$ for full unlimited internet access via your phone.
Simply connect it up as a modem via bluetooth or USB cable.
Worked great for me!
