Frequently Asked Questions about Thailand eSIM

Do I get a phone number with the eSIM?

No. Our eSIMs are data-only, so they do not come with a phone number. You use them for internet access — maps, WhatsApp, email, social media, streaming and any other app. Your existing SIM keeps your own phone number active.

Can I make or receive calls and text messages (SMS)?

Not standard calls or SMS — the eSIM provides mobile data only. You can call and message as much as you like through internet apps such as WhatsApp, FaceTime, Telegram, Signal or Messenger, which run on the eSIM's data. Standard calls and SMS keep working on your usual number through your home operator, as long as you keep that SIM active.

How much data do I need for Thailand?

It depends on the plan you choose. Across nearly 3,000 of our customers' finished eSIMs, the typical one used half to two-thirds of its plan, and on the smaller plans (1-5 GB) about one in three used all of it. Maps and messaging use little; video, video calls and sharing your connection use the most. If in doubt, take the next size up. If you do run out, you can buy another eSIM at any time - you will need WiFi to install it.

What network speeds will I get in Thailand?

Your Thailand eSIM uses a local mobile network: 4G, and 5G where the network offers it. Speed depends on coverage and your location.

Can I use my eSIM for hotspot/tethering?

Yes, but only for Data Plans with a fixed data allowance. Unlimited plans do not support hotspot or tethering.

When should I install my Thailand eSIM?

Install your eSIM while you still have WiFi at home - it is safe to do so days in advance for either plan type. Per-GB plans only start when the eSIM first connects to a network in Thailand. Unlimited plans run on the travel dates you select at checkout, with the days counting from your chosen start date whether the eSIM is installed or not - so make sure it is on your phone by that date.
