Question 1

Does this plan cover me for the whole of Thailand?

Accepted Answer

Yes — definitely. While this page is for Koh Samui, the eSIM provides data coverage across the whole of Thailand, not just Koh Samui. It's the same nationwide Thailand plan, so you'll stay connected wherever your trip takes you across the country — Koh Samui is simply one of the many destinations where your eSIM will work.

Question 2

What exactly is a Thailand eSIM and how does it work?

Accepted Answer

A Thailand eSIM is a digital SIM that allows you to activate a high-speed data plan without a physical chip. For Kiwi travelers heading to Thailand, this means you can bypass expensive roaming daily rates. It works by downloading a network profile to your phone, giving you instant access to local data while keeping your NZ SIM active for calls and texts.

Question 3

Which mobile networks will I connect to in Thailand?

Accepted Answer

Your Thailand eSIM is designed to keep you connected to the strongest available signals. We partner with top-tier providers including AIS, CAT, and more to ensure premium 5G and 4G/LTE coverage. If you are traveling across a region, your eSIM will automatically switch between these local partners as you cross borders, ensuring uninterrupted service.

Question 4

Does my eSIM come with a local phone number?

Accepted Answer

All Thailand eSIM plans are data-only, which is the most cost-effective way for Kiwis to travel. You won't receive a new local phone number, but you can keep using WhatsApp, FaceTime, and Viber with your existing NZ number for calls and messages over data.

Question 5

Can I still use my Spark, One NZ, or 2degrees SIM?

Accepted Answer

Yes. If you still want to receive calls and texts on your NZ SIM while abroad, simply keep it in your phone alongside the Thailand eSIM. Some providers do charge a daily roaming fee for this, so we recommend checking with your NZ carrier before you go.

Question 6

When should I install my Thailand eSIM?

Accepted Answer

We recommend installing your Thailand eSIM the day before you fly or while waiting at the airport in New Zealand. Most plans only begin their "validity period" (e.g., 15 or 30 days) once you actually connect to a network in Thailand. Installing early ensures you have data the moment your plane wheels touch the tarmac.

Question 7

Why do I need to turn on "Data Roaming"?

Accepted Answer

For your Thailand eSIM to access local networks like AIS, CAT, and more, you must toggle "Data Roaming" to ON for the eSIM line in your settings. This is especially important for regional plans (like Europe or Asia) as it allows the eSIM to jump between different countries. Just remember to keep roaming OFF for your NZ SIM to avoid extra charges!

Question 8

Does the eSIM support hotspotting and tethering?

Accepted Answer

Yes, all our Thailand eSIM options support personal hotspots and data sharing. This is perfect for Kiwi families or groups traveling together through Thailand who want to share a single data pool. You can easily tether your laptop, tablet, or another phone as long as your device supports it.

Question 9

Can I have multiple eSIMs on my phone for different regions?

Accepted Answer

Absolutely. Modern iPhones and Androids can store multiple eSIM profiles. You might have one for Australia and another Thailand eSIM for the next leg of your trip. You can simply toggle them on and off in your "Cellular" or "Sim Manager" settings as you move from one destination to the next.

Question 10

What happens if I run out of data in Thailand?

Accepted Answer

If your eSIM supports it, you can top up directly from the 'Your Order' page on our site — the new data is added to your existing eSIM profile, so there's nothing to re-install. If your plan doesn't support top-ups, you can simply purchase a new Thailand eSIM and it'll pick up right where the old one left off.

Question 11

Can I top up my eSIM with more data?

Accepted Answer

Yes — most of our Thailand eSIMs support topping up. When you're running low, head to the 'Your Order' page and click "Top up with more data" to choose an additional data pack or extend your daily plan. Top-ups are charged separately via Stripe and are added to your existing eSIM in seconds, so you can keep using the same profile without re-installing anything.
