What our travelers are saying about the voilà eSIM in Thailand

  • Best eSIM for Thailand! A real travel eSIM.

    Left for 3 weeks in Thailand, from Bangkok to Chiang Mai and then the islands, with a 50 GB plan. No connection issues at all; the local AIS network worked everywhere, even in remote areas of the North, and it was cheaper than more well-known brands like Airalo eSIM or Holafly eSIM. I was comparing eSIM plans before buying, and tracking data usage in the app was great. I'm getting another voilà eSIM for the rest of my road trip in Malaysia and China, one plan per destination, without any roaming fees from a foreign operator. With over 170 countries covered worldwide, I won't look anywhere else for Southeast Asia.

  • Very satisfied with voilà, network everywhere

    Very satisfied with voilà. For our circuit in the north (Chiang Mai, Chiang Rai) and then a week around Phuket, internet was accessible almost everywhere. The network coverage from local operators was stable, as voilà relies on its partner operators AIS and DTAC (the three networks in the country being AIS, DTAC, and True Move H). The 20 GB plan was easy to activate, internet connection was available upon arrival, and there was no physical SIM card to manage. Tracking data usage in the app is practical. To stay connected in Thailand at a good price, I recommend it.

  • Thailand eSIM, great network coverage

    Very good network for my eSIM in Thailand: stable and reliable coverage from Bangkok to the islands, using local operators AIS and DTAC. Customer service was up to the task, with good follow-up on my requests and responsive human support on WhatsApp. Buying an eSIM and activating it only took a few minutes—just scan the QR code, and you're connected as soon as you land. I had tried the Ubigi eSIM before, but I preferred voilà for the value for money and the data tracking in the app. I highly recommend it. Cheers.

  • Perfect for island hopping, one small downside

    Backpacking trip between Koh Samui, Koh Phangan, and Koh Tao. The network coverage from local operators (DTAC here) was back as soon as we arrived at the port after ferry crossings, perfect for keeping the internet and Google Maps active. 10 GB of data was more than enough for 12 days. The only downside: you have to activate data roaming for the eSIM yourself in your device settings; it's not 100% automatic. The activation instructions to install the eSIM and the help center are clear, so you figure it out quickly. For this price, the voilà eSIM remains unbeatable in Thailand.

  • Impeccable service for Thailand, unbeatable prices

    At first, I had my doubts: the price of the voilà eSIM plans for Thailand was much lower than other providers, so I expected mediocre service. It was actually the opposite. Buying an eSIM took just two minutes—scan the QR code received via email, instant activation, and no physical SIM card to hunt for in a 7-Eleven. I got the 20 GB plan, and the DTAC network was stable from Bangkok all the way to Krabi. And the customer service blew me away: I asked a question on WhatsApp and got a response within minutes from a human support agent who already knew my file, not a robot. The help center is also very clear. For Thailand, it's definitely the best value for money.

  • Remote work in Chiang Mai, 50 GB without overages

    One month of remote work in Chiang Mai, 50 GB without going over. The voilà 5G via the local provider AIS stayed stable in cafes and coworking spaces. A huge advantage: data sharing (unlimited hotspot) saved me so I could connect my laptop from my smartphone. ChatGPT, Slack, banking apps: everything works. A colleague uses Yesim, but after comparing the price per GB, the responsive customer service, and the human support on WhatsApp, I preferred voilà. The eSIM is compatible with all recent devices, with one-click activation in the app.

  • ultra-practical eSIM

    ultra-practical eSIM. For Thailand, I got their eSIM and the connection was perfect for 3 weeks, with AIS network everywhere, from Bangkok to Krabi, without any drops. And it was cheaper than other options: I had compared, and voilà was well below Saily for an equivalent plan. The plan is easy to activate—just scan the QR code, track your data usage in the app, and zero roaming fees. I preferred voilà, it's perfect for staying connected while traveling in Thailand.

  • cheapest Thailand eSIM, 1-click activation

    Solo in Bangkok and then Ayutthaya for the temples, 10 GB was enough. I had compared eSIM plans: voilà comes out to €0.81 per GB compared to €1.48 for an Airalo eSIM, and the Ubigi eSIM is even more expensive. I preferred voilà, clearly the best eSIM plan for this destination. Scanned the QR code before leaving, the DTAC connection started instantly upon landing, zero roaming fees. Grab and Google Maps running continuously, followed by tracking usage in the app. The eSIM comparison was clear.

  • eSIM activated at Bangkok airport in 2 minutes

    We took an Airalo eSIM last year (DTAC network) and activation was a struggle. This time, we went with a voilà eSIM: as soon as we landed at Suvarnabhumi, the AIS 4G internet connection kicked in instantly; by the time we grabbed our luggage, we were already ordering a Grab. 10 days for the two of us, 20 GB shared via hotspot (tethering included), Google Maps, and banking apps without any blocks, all totally secure. The eSIM is compatible with both our devices, and our main phone numbers stayed active for calls at the same time. I had also looked at the Nomad eSIM, but I preferred voilà—it's simpler and cheaper. Stayed in Bangkok then Krabi, nothing to complain about.

    Camille.L
  • Very good value for money, just no unlimited data.

    A week in Bangkok, a 5 GB plan for €6.50, which was more than enough for Google Maps, WhatsApp, and Grab. With the various plan options (from 1 to 50 GB), it's easy to choose based on your needs and budget. The only thing: voilà doesn't offer unlimited data like Holafly eSIM, so if you stream a lot, aim for 20 or 50 GB. For typical traveler usage, it was perfect, and about three times cheaper than the unlimited plans elsewhere. The price shown at the time of purchase is the final price—simple and without surprises. I'll definitely use it again.

  • Full moon party in Koh Phangan, top-notch connection

    Traveling with friends for the full moon party in Koh Phangan, with a quick diving trip to Koh Tao. 20 GB plan, using the AIS network which even worked on the beach. I had used a Saily eSIM during a previous trip, but the Saily eSIM ended up being more expensive and the support was slow. I preferred voilà: buying an eSIM was more affordable, data sharing was included, and customer service responds really fast on WhatsApp. Everything is done from France before you leave, with one-click activation.

    Inès_voyage
  • Cheaper than a Holafly eSIM, with real-time usage tracking

    I compared the Holafly eSIM and voilà before leaving. The Holafly eSIM offers unlimited data, but it's expensive and the speed is throttled after a certain limit. I preferred voilà: 20 GB for €16.20, data usage tracking in the app, and top-ups in just two clicks. Stayed in Chiang Mai then Pai, the AIS network was stable, and banking apps and Google Maps worked perfectly. The plan pricing is transparent, with no subscriptions. The best eSIM plan I've found for Thailand, and clearly cheaper than the Holafly eSIM.

An eSIM package is associated with a single device, the one on which it has been activated. To use an eSIM on another phone, you'll need to purchase a new one directly from that device.
