I am visiting Thailand for up to 3 months (in, and out). Which network do you use? Which prepaid plan do you have? What provider has the cheapest SMS rates? I am interested in sending SMS (to local mobiles only). No roaming, no international, no nothing, just the cheapest local SMS. Sending/recieving messages are more important for me than voice calls. I have an old Nokia GSM phone, it is triband, and 2G comptabile, and that's good enough for me. I have researched the best options online, and it seems AIS (confusing website), or DTAC (Happy tourist sim card) are the best options. Other options include True Move, Hutch, & TOT. What do you think? Please help me choose the right provider based on the above information. Thanks!

What is your target/budget per SMS?

Without a lot more detail my best guess would be a "Buffet" SMS option?

One-2-Call have a 500 SMS for 119 baht package. http://www.ais.co.th/12call/en/pro-AddedServices.html

Most people here are now using free messaging apps. like WhatsApp!

I have had an AIS sim for the last 8 years. Good coverage and they always have some good deals running. 49 Baht from any 7/11 and away you go. very helpful English speaking customer service staff as well I might add

I'm not sure what Whatsup is, is it like text messaging or like chatting? How does it work?

3 baht/sms is too expensive, and is that the rate for both DTAC, and AIS, and do both of them offer SMS packs, or just AIS?

i should defineitly get a SMS pack, i will probably send 5-20 sms/day, and 500SMS/119baht sounds like the pack for me, but is the offer still active, can anyone confirm they're using it? How many days before the validity expires, do i have 30 days to use the 500SMS, before i need to buy a new SMS pack again?

Maybe that promotion has expired? You can always ask if they still offer it.

One-2-Call seems to have this set of SMS packages curently: http://www.ais.co.th/12call/en/promotion_special.html

So 150 baht (does not include 7% VAT), for 200 SMSes over 30 days.

TrueMove have this promotion, which may still be available: http://www.truemove.com/en/banner-sms-mms-pre.htm

Not sure if these DTAC packages extend to the Happy pre-paid brand: http://vas.dtac.co.th/en/smspackage.htm

Thanks for that info, it appears AIS has 4 different prepaid SIM packs, look here

Is it the Freedom SIM have to get to subscribe for the SMS pack

CAN anyone verify DTAC Happy prepaid works with SMS packs, 200sms (139baht)???
