ORIGINAL POSTER
I will arrive in BKK on November 22nd. Normally I buy a 30 day SIM card from AIS at the airport. This; Because I never stayed longer than 30 days in a row. I then reactivated the card when I return after a month or a few weeks in another country. This time I come with a 6 month visa. So I can (and will) stay 4 months. (interupted halfway by 5 days Kuala lumpur.

Who gives me the best advice for a SIM card with a lot of data for about 4 months or longer?

TLDR : Answer Summary
The discussion revolves around recommendations for SIM cards suitable for a 4-month stay in Thailand with a focus on value for data and calls. Several users suggest various options, including unlimited data plans from AIS, DTAC, and TrueMove, as well as mentions of E-SIMs. Key suggestions include purchasing a SIM at 7-11 or local stores rather than the airport to avoid high prices, considering packages like DTAC's unlimited data plan for 200 baht or AIS's 6-month plan with significant data allowances. The conversation also highlights the benefits of online ordering and loyalty to existing providers.

Get a 50baht sim at some shop like 711 when you land. You should get a few GB. The best deal after that is in my opinion f FINNMOBILE which operates on Dtac network. You can subscribe online with a scan of your passport. Sim is delivered by mail usually 2days later.

🤳🏻My plan is Finn Extreme : 60gb at 100mbps speed, 600minutes and unlimited data at 20mbps (which is still a nice speed and better than most packages suggested here) for 329thb

💸You can get 10thb discount per month with my link :

AIS has a sim or package for 6 months at 1200, which works out 200 a month. It gives you 30gb a month

Do not buy anything in airports.

When arrived at the destination, ask which compagny covers best there.

Don’t forget that many places have free wifi, even some beaches.

Personal I'm still using the AIS Sim from the airport and just top up the data, don't use calls or text much and if I do it's via WhatsApp, line etc, just top up data when I need to it's not expensive and been here for 6 months at the moment and it's still going strong. Don't over think it and enjoy your time 🙂

ซิมเทพ is what I use when visiting Thailand as I never know when I’d leave the country, you can order from shopee or Lazada . There are 3,6,&12 months one time prepaid and that gives me more then enough data. It also comes with free calling , that’s enough for me as I mostly use the internet. The price are from 5-600 to 2,000 whichever suited your needs.

I’m not selling it or have any gains but feel free to DM me if you’re not sure if what I mean. Can’t post it here as I do not sure if the group’s policies.

You can get these sim at any telephone store too, the prices is a bet higher though.

Cheapest is NT Telecom with unlimited max speed for 6 months for 599B but this is data only (no calls) and coverage is not as good as AIS. I have used it as an internet backup as it really is unlimited and can tether. I get around 30Mbps down, but only 5 up at home in Chiang Mai.

I guess it's on purpose, the pricing is stupid sometimes when you compare the packages (which often have low speed, who needs unlimited data at 512kbps ? 🤣).I ended up with FINNMOBILE.

 if on holiday and you only need a sim to call a taxi or check a route low speed and cheap is ok, as majority of planning i do evening before using hotel wifi, each situation is different so great to have a choice

 Sure , everybody's situation is different :) It's really a headache to navigate the offers when you arrive here for your first stay/holiday. For holidays I would strongly advise to never buy a tourist SIM but rather start with the Dtac happy combo sim (for those not in the know, prices on app for topups are always mentioned without tax, so add 7%)

Just use the sim you've been using as it sounds like you're happy enough with it, just top up every 30 days like you did when leaving for a few days and coming back. Only this time you're not leaving. And you get to keep your number, and LINE account if it's attached to that number
