Planning your trip to Thailand and getting ready for your departure is an exciting time. You’ve likely got a few lists going of what to pack and what you still need to get for your trip – currency, sun cream, your swimsuit, camera, and passport. One thing that’s commonly overlooked is a local sim card.

There’s nothing more frustrating or inconvenient than finding yourself suddenly without coverage when you need it most or waiting for pages to load on an epically slow connection. Failing to organize a local sim for Thailand is likely to result in just this scenario.

In this post, we’ll cover all the things you need to be aware of when choosing a sim card for Thailand. We’ll cover topics like price, coverage, and the best places to purchase sim cards in Thailand.

Why Buy a Sim Card for Thailand?

Our phones have become indispensable tools for daily life. When we’re traveling, our phones are an invaluable tool. Things like currency conversions, finding our way around, translations, and even documenting our travels are now taken care of by one handy device that fits in your pocket.

Sure, you can chance using your native sim card in Thailand and hope that you’re not left without coverage at a crucial moment. Unfortunately, this is likely to also result in a phone bill bloated with roaming charges and eyewatering data prices. 

Getting a local sim card for Thailand can help avoid any unnecessary drama and frustration and save you money in the end. Thailand’s 5G network is pretty robust so there’s that to consider too. Basically, getting the right sim will just make your Thailand backpacking trip better OK!

    Buying a Sim Card for Thailand – Things to Consider

    Your personal needs and preferences will determine what makes the best sim card in Thailand for you, so there’s no universal solution. But we’ve addressed the important considerations below.

    Price

    Everyone loves a good deal, right? The good news is that there are plenty of great deals out there to be had. There are also things to avoid.

    Don’t be lured in with the promise of a free sim. While this sounds appealing, beware. Often there’s hardly any data on it, and you’ll need to top up almost immediately – often at a premium.

    Data

    Data is cheap in Thailand (Thailand is still kinda cheap). Providers are constantly updating their deals and competing with one another which works out great for you! 

    Not sure how much data you’ll need? Spend some time understanding your daily usage and then add some padding to that figure – you’ll invariably use more data on your travels. 

    If your phone is locked to a network and buying a sim in Thailand isn’t an option, then consider a portable Wi-Fi device. These give you unlimited data and you can connect up to five devices at a time.

    Coverage

    Where in are you going to stay in Thailand? If you’re hitting top touristy spots like Phuket, Bangkok, and Chiang Mai, coverage isn’t an issue at all, so you can choose any provider.

    If you’re planning to hit the islands, AIS is a good local option for good coverage in most of Thailand. If you need 5G while you hop from island to island, then True Move is recommended.

    Local provider DTAC is a bit behind the others in terms of 5G and won’t be of use if you’re heading to really off-the-beaten-track destinations.

    Bureaucracy

    It used to be much easier to purchase a sim card in Thailand. These days, you’ll need your passport to get a sim at a retailer or reseller.

    You can still get sim cards in Thailand from street vendors who won’t require your ID but we wouldn’t recommend these. 

    Expiration

    When purchasing a sim card for Thailand it’s important to check the validity. Some sim cards expire in as little as eight days. 

    The Future of the SIM Card is HERE!

    A new country, a new contract, a new piece of plastic – booooring. Instead, buy an eSIM!

    An eSIM works just like an app: you buy it, you download it, and BOOM! You’re connected. It’s just that easy.

    Where to Buy a Sim Card for Thailand

    Sim cards can be purchased in a range of locations in Thailand – from airports to street vendors, and convenience stores.

    In the Airport

    Purchasing a sim card for Thailand at the airport will be slightly more expensive than in other locations. That said, it can be worth the expense to get online and set up before you even leave the airport. Local providers have a strong presence at international airports, so you’ll have your pick.

    At a Store

    Official provider stores are easy to come by in Thailand. Sales staff generally speak a good level of English and are very helpful in getting you up and running in no time.

    Convenience stores are not…well, convenient when it comes to purchasing a prepaid sim in Thailand. Firstly, the package information is all in Thai. Even if you do find what you’re looking for, you’ll still need to activate that sim and usually, staff aren’t able to assist in English.

    Online

    Purchasing your sim card for Thailand online is a great way to ensure you have enough time to do your research, make an informed decision, and receive your sim card before you depart. No precious holiday time is wasted standing in a queue at a cell phone shop.

    Street Vendors

    We mentioned that you can purchase sim cards from street vendors in Thailand. They won’t require proof of identification or your passport, but we still wouldn’t recommend this option.

    Best Sim Card Providers in Thailand

    There are two really great providers for sim cards in Thailand that offer great coverage and good rates.

Whilst they don’t offer a specialised Greece sim card, they do have a different array of International Sim Cards that will work in many different countries including Thailand.

    One Sim Card

    This is a great option for regular travelers who visit a number of different countries or simply make repeat visits to the same country.
