What are the best options for purchasing a SIM card in Thailand for international use?

Well if you got Verizon I feel for you, I just dropped my plan. It works fine until you 10gig of data runs out and then your phone is no more than a brick until next cycle or you spend stupid amounts of money just to get 2 extra gigs. Like people say there's wifi everywhere, so you can use WhatsApp, line heck even call on Facebook messenger. I got a Thai sim card but just for data and Thailand calls, international calls I use one of the above mentioned. Good luck

When you say you can 'use' it, does than mean you have a plan that doesn't include it? If so, no way i would buy the add on international day pass. I'm here now and have the Verizon Unlimited Ultimate Plan and it works great. No problems at all, and can't beat that international is INCLUDED in the price! I also have a Thai SIM card in my other phone, but that's only because I'm going to be here long term. If you'll be here 2 months or less, you won't need a Thai SIM card, unless you just want one. If you use your Verizon plan for more than several months overseas, I've read where they 'could' suspend international service, but people on here have said they've used it for much longer with no issues. I didn't want to chance it because I'll be traveling to multiple countries and it's nice to have a phone when I first land before I can get a SIM card if I decide to. If you get a SIM card here, mine gives me unlimited data and calls in Thailand. To call back home without using my plan, I can also use WiFi calling and it won't show up on my plan usage. It's free, just make sure to set your phone to WiFi Calling in the settings before you leave the US. You can also use FB Messenger, IG, Skype, etc to call back home, they work great also. Most people here use WhatsApp and Line, even businesses, so you call or message them using your data. I have AIS and they are prob one of if not the largest and most reliable carriers here. I did some research and that's who I chose. The initial payment for the SIM card and first month was $500 baht, and after that I reup it for $200 baht per month ($6!). I've been pretty impressed with it. So as you can see, you have lots of options, so that's one LESS thing to worry about for your trip. 😁 I'll include a pic of some good Apps to download before you get here.

Enjoy!

For International calls only, no need for a SIM. Go online and look up yolla.com. VERY cheap to call the U.S. or wherever. I can call Internationally from the U.S. too..and very cheap(not necessary that much nowadays if your friends/fam have the same Social Media website to call(FB, WhatsApp, Viber, etc).

Wi fi everywhere ,don't stress

If you get a sim or e-sim and have access to internet then use Skype. I’m from the US as well and my calls cost around two cents a minute. You do have to buy time and you can even get a US phone number.

Get a Google Voice number. With wifi you can call and it looks like a domestic call to those you call.

I have T-mobile Intl, and I don't use anything else,,,messenger/whatsapp/Line etc, unlimited data, and actual calls 25c,,but whoever needs that anymore,,

If your phone is locked, you can buy a cheap unlocked phone with a Thai SIM and use it as a Wi-Fi hot-spot. Otherwise, go to AIS counter at airport (at arrivals) and they will set up the SIM and data connection in less than 10 minutes. Other companies like True and DTac are also good

If your phone takes an esim but Airalo Asialink

You need to make sure your phone is unlocked from Verizon to use a Thai SIM card. Is your phone paid in full and unlocked? This is the first step

Go to in thailand n the staff there will help u load up a sim card n u also show them your passport to upload n after that all phones numbers transfer to whatsaap n there u go free calls anywhere in the world
