Firstly here's what i do for my AIS number.

*129*1# activates the internet. Restarts phone to get internet to work.

Then dial in to subscribe to whatever package i want, restart phone again.

Is this the same for true move H? So far i don't know what sort of number to dial to activate their internet.

Can someone provide me the entire list of packages they have available. I don't live in thailand i just visit occassionally typically for say like 1 week up till 10 days and then i won't visit again until a couple of months later.

This has been discussed recently in this thread: Thai Holiday: True Move H...... Some Question

If you are a pre-pay TrueMove-H SIM user, yes there are package activation codes you can use, depending on if you just want add-on data, or call and data. Take a look at the following TRUE pages for package options:

iNet for Internet Lovers

iSmart for Internet and Chat Lovers, Voice and Data Plan

Mine was activated by default when I swapped my old prepay True InterSIM for a new prepay TrueH SIM (free exchange). All I had to do was remember to turn data off on my phone so as not to be charged for it!

For some unknown reason they credit me with 100MB of data for nothing every month.
