Frequently Asked Questions
What is the cheapest eSIM for Thailand?
The cheapest Thailand eSIM on MobiMatter costs $3.49 for 3 GB, valid for 7 days. Prices come live from 7 vetted providers and change often; the price on this page is the current one.
Is it worth getting an eSIM for Thailand?
For most tourists and business travellers, yes, if your phone supports eSIM. Thailand plans start at $3.49 for 3 GB, and you install the eSIM before you fly, so you have data when you land, without queuing for a tourist SIM at the airport. If your home plan already covers Thailand at no extra cost, you may not need one.
Which networks do Thailand eSIMs use?
Thailand eSIMs on MobiMatter run on AIS, TrueMove H, dtac, and True Move H. Every plan names its network, so you can choose the carrier you prefer before you buy.
Which eSIM is best for Thailand?
Our best plan for Thailand right now is 50 GB for 10 days at $9.99 from True. We rank plans on quality and value for money, and this one comes first in the list.
How much data do I need for a week in Thailand?
It depends on how you use your phone. Light use (maps, messaging, browsing) takes about 0.5–1 GB a day; scrolling a lot of social video can take 2–3 GB or more. Typical use per hour:
- Instagram Reels, TikTok: 0.3–1 GB
- YouTube, Netflix at standard quality: 0.5–1 GB
- Video calls (WhatsApp, FaceTime): 0.5–1 GB
- Voice calls (WhatsApp, FaceTime Audio): 50–70 MB
- Maps and navigation: 2–6 MB
- Messaging and browsing: 50–150 MB
The cheapest Thailand plan with at least 5 GB for a week or longer is 5 GB for 15 days at $4.99.
Do Thailand eSIMs support 5G and hotspot?
5G is available on 31 plans for Thailand, where the local network has 5G coverage; the others use 4G/LTE. Hotspot (tethering) works on every plan, so you can share your data with other devices.
Does a Thailand eSIM come with a phone number?
Most travel eSIMs, including most Thailand plans, are data-only and have no local number. You keep your usual number on your main SIM for calls, texts and WhatsApp. Plans that include a number or minutes say so on the plan page.
Will my phone work with a Thailand eSIM?
Yes, if it supports eSIM and is not locked to a carrier. To check, dial *#06#: if an EID number appears, your phone supports eSIM. Most iPhones from the XS/XR on, Galaxy S20 and later and Pixel 3 and later do, except models sold in mainland China.
Can I keep my own SIM and WhatsApp while using a Thailand eSIM?
Yes. Your eSIM and your main SIM can be active at the same time. Use the eSIM for mobile data with data roaming on for that line, and turn data roaming off on your home SIM to avoid charges. WhatsApp keeps working on your usual number.

The cheapest eSIM app I’ve found so far. I thought I had made a mistake while installing the eSIM, so I contacted customer support. They replied to my email within just 3 minutes and helped me right away. I also had no problems with the internet connection. Overall, a great experience!

I have been using it for about 2 years and I am very satisfied. I used it in Greece, Bulgaria, and Romania, and I experienced internet speeds that I haven't seen in Turkey.

I used it smoothly and quickly in the Netherlands, Belgium, Germany, Spain, and Bulgaria. Sparks connects to the most suitable network for your location at that moment, allowing for convenient use. Depending on your travel plans, annual options are very advantageous because it consumes very little internet data there, unlike in Türkiye.

The Ultimate Southeast Asia Hopper Guide: Travel Thailand, Vietnam, Singapore & Bali on One eSIM
Southeast Asia welcomed more than 198 million international visitors in 2025, a figure that surpassed pre-pandemic travel levels by 12 percent, according to recent backpacker travel data. A large share of that traffic is not single-destination tourism. It is the modern version of the Banana Pancake Trail, where travelers land in Singapore, island-hop through Bali, land in Bangkok, and finish along Vietnam's coast in Da Nang, all inside one trip. The route has existed for decades, but the way tra...
