AvailabilityEdit

Can be purchased from many small mobile shops, in most towns. However many mobile shops only offer top up or talk-only services, not data - you may need to try several shops before you find one selling NetSim packages. Purchasing a Sim usually comes with some data included (something between ฿50 - 150 for Sim plus nominal balance. Sometimes bonus balance is included as hours pre-set, other times you need to send a code to make sure your bonus balance is credited as a timed data package or you'll be using the default rate and that disappears VERY quickly!

Suggestion: go to official AIS shops (Telewiz) and tell them that you need data access for this number of days that you will spend on your trip in the country. They will find the cheapest pre-paid option for you. You can even ask them to get Micro-SIM in case you are an iPhone 4 or an iPad user. As long as you stick with pre-paid options, then you won't lose more money than what you pay right in front of them.

SIM sizes Edit

• Standard SIM and Micro SIM available (exchangable at any AIS Telewiz shops)

Tethering Edit

Available. Carrier Update may required for iPhone users.

Turning GPRS (mobile data) onEdit

Sometimes, after a period of not using your SIM, GPRS (mobile data) is turned off automatically. Without GPRS you won't be able to access any data, no matter how much credit you have.

• To check the status of your GPRS dial: * 129 #
• To turn GPRS on if it has been deactivated, dial: * 129 * 2 #. You'll receive an SMS confirmation within a few minutes, once received turn your phone off then on again to activate.
