As far as i know DTAC has the weakest 3G coverage, the only advantage over i-mobile is that it has fallover to 2G network when there is no coverage available. As the DTAC 3G is on 850 MHz my handsets can not use it so i could not perform any live check.

I see. How about True Move?

same problem for me: 3G on 850 MHz.
But i often use the TrueMove InterSIM which has good data rates and 1 THB/min to all main international destinations. EDGE works quite good with them...

Are you using the SIM in Mifi? or just smartphone?

As I know, Truemove has TRUE-H SIM Pack, 49bth/1 day unlimited. Do you think it is a good option? And, this SIM is for smartphone only?

i have a smartphone and use wifi tethering when needed.
You can use all data options on all true SIM cards, so you can buy the one for cheapest calls and just activate the day package as well...

There are 2 day packages:
39 THB = unlimited EDGE
49 THB = unlimited EDGE + a few hours on wifi hotspots
to activate send D1 or D2 by sms to 9789

Thanks for your information. By the way, I can't find the 2 day package? All I can find is a 49bth for 1 day unlimited.

I got it. "2" one day packages

yes you got it ;-) As the wifi hotspots are mostly totally overloaded you can also take the 39 THB version and forget about the wifi. I found that EDGE was often faster than the wifi... arrr

I can only find the 49bth daily unlimited plan in True-H website. I can't find the 39 THB version :confused:

yes, their website is more or less useless... Just SMS D1 instead of D2 and you will get the 39THB package. They will be able to show you a complete price list only in the TRUE shops (and only after lengthly discussions)...

Oh... I see, thanks again:)

BTW, I have sent you a message :)
