If you're traveling from Argentina to Thailand, you already know that roaming from your local carrier can be a very unpleasant surprise upon return: bills for tens or even hundreds of dollars/euros for just a few days of data. There's a much smarter solution: a Thailand-specific eSIM.

In this guide, we'll explain exactly how it works, how much you can save compared to roaming with your Argentine carrier, and how to activate your PuraSim eSIM before boarding your flight.

With PuraSim, you get local data in Thailand from the moment you land, at a local price, with no commitments and without changing your physical SIM card.

Roaming from Argentina to Thailand: what it really costs

Argentine carriers offer international roaming packages for Thailand, but the prices are rarely competitive. Depending on your carrier, a day of data in Thailand can cost you between 15-25 USD/EUR per day.

Let's look at a real example: if your trip to Thailand lasts 10 days and you use data moderately (maps, messages, social media), with traditional roaming you could pay between 150 and 250 euros/dollars just for connectivity. With a PuraSim eSIM for Thailand, that same consumption would cost a fraction.

In addition to the cost, roaming has other limitations:

  • Reduced speed often to 3G or even 2G
  • Very low daily data cap before your speed is cut off
  • You need to activate the service before leaving (and pay for it even if you don't use it)

A PuraSim eSIM eliminates all these problems: you pay once for the GB you need, you get real 4G/5G speed, and you activate it only when you need it.

How an eSIM for Thailand works

The eSIM (embedded SIM) is a digital SIM that lives inside your phone. There's no physical card to insert: you download the carrier profile using a QR code, and that's it. Your phone can have several eSIMs installed simultaneously and switch between them in seconds.

For travelers from Argentina to Thailand, the process is like this:

  1. You buy your data plan at purasim.com before leaving
  2. You receive the QR code by email
  3. You install the eSIM on your phone from home (in 5 minutes)
  4. Upon landing in Thailand, you activate the eSIM and you already have local data
  5. Your Argentine SIM continues to work for receiving calls and SMS

No need to go to any store. No need to queue. No need to look for a phone shop upon arrival at Thailand airport. You arrive and you already have internet working.

How many GB do you need for Thailand?

For a trip from Argentina to Thailand, our recommendation is 15-20 GB for 14 days. This is enough for most common uses: Google Maps all day, WhatsApp with family and friends in Argentina, Instagram, occasional searches, and some occasional video calls.

Typical daily consumption breakdown:

  • Google Maps actively navigating: ~150 MB/day
  • WhatsApp with messages and photos: ~100 MB/day
  • Instagram and social media (no video): ~300 MB/day
  • Searches and websites: ~100 MB/day
  • Estimated total: 600-700 MB/day for moderate use

If you're going to work remotely, make frequent video calls, or upload real-time content, consider a higher plan. PuraSim plans have top-up available if you run out, so you can always extend.

Tip: The Buenos Aires-Bangkok flight has layovers in Dubai or Doha; take advantage of the connection layers to activate the Thai eSIM

How to activate your eSIM before your flight

The best thing about PuraSim eSIMs is that you can have it ready before leaving Argentina. The installation process takes about 5 minutes and you only need WiFi:

  1. Check compatibility: ensure your phone supports eSIM (iPhone XS or higher, Samsung Galaxy S20+, Google Pixel 3+ and many more).
  2. Buy your plan at purasim.com. Select Thailand as the destination and the GB plan you need.
  3. Install the eSIM: open the email with the QR code and go to your phone's Settings to scan the code and download the profile.
  4. Configure the eSIM: give it a recognizable name (e.g., "PuraSim Thailand") and make sure it's configured for data but NOT for calls or SMS (you keep those on your Argentine SIM).
  5. Activate upon arrival: on the plane, you can have the eSIM installed but inactive. Upon landing in Thailand, go to Settings → Mobile Data and activate the PuraSim eSIM.

In less than 5 minutes after landing, you'll have full data in Thailand without leaving the airport.

Tips for travelers from Argentina to Thailand

Beyond connectivity, here are some specific tips for travelers from Argentina:

  • Download everything before you leave: offline maps of Bangkok, Chiang Mai, Koh Samui, and Krabi on Google Maps, playlists on Spotify, Netflix episodes for the flight. You won't have data during the first few hours of your flight.
  • Notify your bank: many Argentine banks block transactions in Thailand for security reasons. Inform them of your trip to prevent your card from being blocked at the worst possible time.
  • WhatsApp will work perfectly: with the eSIM active, you can call and chat with family and friends in Argentina without additional international call charges.
  • Save documents offline: scan your passport, travel insurance, and reservations and save them on your mobile. If there's a moment without data, you'll still have access.

And remember: The Buenos Aires-Bangkok flight has layovers in Dubai or Doha; take advantage of the connection layers to activate the Thai eSIM

With PuraSim connected, your trip from Argentina to Thailand starts seamlessly from the very first moment.

Frequently asked questions

Can I still use my Argentine number in Thailand?

Yes. The PuraSim eSIM operates in a separate virtual slot from your physical Argentine SIM. You'll continue to receive calls and SMS on your usual number. To call Argentine numbers, use WhatsApp or similar services through the eSIM.

How long does the eSIM for Thailand last?

PuraSim plans have a specified duration (7, 10, 15, 30 days). The countdown starts from the first data usage, not from installation. You can install it days in advance without it starting to count.

Can I buy the eSIM for Thailand once I'm already there?

Yes, as long as you have WiFi access. You can buy and activate the eSIM from the airport or hotel WiFi. However, we recommend doing it before you leave to avoid relying on WiFi upon arrival.

Does the PuraSim eSIM for Thailand include calls?

PuraSim data plans are data-only plans. For local calls in Thailand or international calls to Argentina, use WhatsApp, Telegram, or FaceTime, which work through the eSIM's data at no additional cost.

What if I have problems with the eSIM in Thailand?

PuraSim support is available 24/7. If the eSIM doesn't connect automatically, try selecting the network manually in Settings → Mobile Data → Network. If the problem persists, contact support via chat or email with your order number.
