BTW, do you know how to check balance/usage from the phone? Was not clear from the website.


https://www.dtac.co.th/en/prepaid/se...ppynumber.html

*101*9# SEND

Check remaining balance, remaining Emergency Refill and expiry date
Direct Number (USSD)*101*9#

IVR*1001 Press 9

Interactive USSD (UMB) Dial *100*9#When your mobile displays menu for you to choose reply, please choose and type reply menu number 1 and follow the steps.

You may be able to use the web as well:

https://my.dtac.co.th/esv/en/login (request a pin code sent to your phone)

or even an app:

https://itunes.apple.com/th/app/dtac...8142?l=th&mt=8

https://play.google.com/store/apps/d....android&hl=en

(you need to be on a mobile data connection - not WiFi - for these apps to work.)

After the period is up on the tourist SIM, you would have to add value and subscribe to another data plan; the 229 baht would not automatically recharge.
