The story behind BuddySIM

Rafael Gomez, BuddySIM founder and eSIM expert

BuddySIM was born during my parental leave, out of real frustration. Expensive roaming fees, stressful queues at the airport with small children and a complicated hunt for SIM cards on site? It doesn't have to be like that.

A holiday is the best time of the year and should be worry-free! That's why I founded BuddySIM, so you can focus on what matters most on holiday: relaxing and spending time with your loved ones.

eSIM for Thailand: online instantly, travel flexibly and avoid roaming charges

With an eSIM for Thailand you are online from the very moment you arrive, saving yourself 

  • a long search for local SIM cards 
  • and protecting yourself from roaming charges.

More and more travellers swear by this digital SIM card because it stands for flexibility, comfort and transparent rates. Within the EU in particular, clear roaming rules have applied since 2017. Outside the EU, however, including Thailand, using your home SIM still often incurs high charges.

A local eSIM sidesteps this problem elegantly and completely. In accordance with the ePrivacy Directive and GDPR, it is also ensured that eSIM providers too must comply with European data protection standards.

What is an eSIM? The benefits for travellers to Thailand

An eSIM is the digital form of the classic SIM card, loaded directly onto your smartphone – after which any swapping is a thing of the past. 

For Thailand in particular there are crystal-clear benefits: 

  • No searching for local shops, 
  • no paperwork, 
  • no wrangling with language barriers. 

You order the eSIM conveniently from home. After landing you are mobile straight away and enjoy high-speed internet with the best network operators.

The BuddySIM eSIM Thailand Unlimited package uses multi-carrier technology and can contribute to a stable connection even in more remote regions. 

No registration, entirely contract-free, always prepaid – so travelling in Thailand stays simple. The offer aims to enable cost-transparent rates.

How activation works: three steps to your eSIM for Thailand

  1. Buy your preferred package online from BuddySIM.
  2. Receive the QR code directly by email and scan it with your smartphone.
  3. The eSIM is activated in less than 30 seconds – done!

Thanks to multi-carrier support (Dtac, AIS, True), the plan automatically switches to the strongest network at all times, ensuring top reception in Bangkok, on the beach or up in the mountains.

What to look out for: compatibility & validity

Not every phone supports eSIMs: so check in advance whether your device is compatible. 

BuddySIM provides a clear overview and proven guides for this. The flexibility of the validity periods stands out: 

Are you travelling to Thailand for 10 days, 14 days or a month? With BuddySIM you choose your package to match your trip from 3, 7, 10, 15, 21 or 30 days. That way you are always on the safe side!

eSIM for Thailand compared – which provider is worth it?

The market is booming: providers like Holafly, BuddySIM or Saily offer different focuses. 

  • While Holafly relies on a super-simple app and unlimited data volume, 
  • BuddySIM impresses with multi-network support, a No-Net-No-Pay guarantee and genuine 24-hour support. 
  • With Saily, the focus is on affordable entry-level packages (particularly interesting for short stays).
