Thailand eSIM: Travel Data Plans

Description

Our Thailand eSIM keeps you connected in Bangkok, Phuket, Chiang Mai and the islands, without UK roaming charges. You will use data for ride and food delivery apps, ferry times, maps and messages home, so having your own connection from the airport makes the trip easier. Plans go from 1 GB for a week to Unlimited for 30 days.

Thailand eSIM plans and prices

Card and PayPal payments add a small fee shown at checkout. Bank transfer has no fee.

Which Thailand eSIM plan should I choose?

Two weeks of normal use (maps, ride apps, WhatsApp, photos) fits in 5 GB to 10 GB. Heavy social media and video calls: 20 GB or Unlimited. Thailand’s Unlimited 30-day plan is one of our cheapest Unlimited options.

Unlimited plans may slow down after heavy daily use under the local network’s fair-use rules. If you need to share your phone’s internet (hotspot), message us before you buy.

Who is this Thailand eSIM for?

• Backpacking routes from Bangkok to the islands
• Two-week beach holidays in Phuket, Krabi or Koh Samui
• Longer stays in Chiang Mai
• Anyone who wants data on arrival instead of queuing for a SIM at the airport

Using data in Thailand

• Ride apps and food delivery are used everywhere in Bangkok and the resort towns, and they need data to work.
• Island-hopping days on boats can use more battery and data than you expect. Download offline maps before you set off.
• Coverage is good in cities and main tourist areas. Signal can be weaker on remote islands and in the mountains.

How to set up your Thailand eSIM

1. Check your phone supports eSIM and is unlocked. Not sure? Read our guide to unlocking your phone.
2. Choose your Thailand plan above and pay by card, PayPal or bank transfer.
3. We email your QR code by hand, 10am to 8pm, every day.
4. At home on Wi-Fi, scan it in Settings (Mobile Data or SIM manager, then Add eSIM). When you land in Thailand, switch that line on and turn on data roaming for the eSIM only.

Before you travel, it is worth reading the GOV.UK travel advice for Thailand.

Thailand eSIM questions

Do I need a Thai SIM card or is an eSIM enough?

For data, an eSIM is enough. You only need a Thai number if a local service insists on texting you a code.

Does the eSIM work on the Thai islands?

It uses local mobile networks, so it works where they have signal: well in towns and resorts, less on remote beaches and at sea.

When will I get my Thailand eSIM QR code?

We email QR codes by hand during shop hours, 10am to 8pm, every day. Order at least a day before you fly, so you can install it at home on Wi-Fi.

Can I keep my UK number?

Yes, if your phone has dual SIM. Your UK SIM stays in for calls and texts (your UK network’s roaming rates apply to those), and the eSIM handles data. WhatsApp keeps your usual number.

Is my phone eSIM compatible?

Most recent phones are: iPhone 11 or newer, Samsung Galaxy S20 or newer, Google Pixel 3 or newer. The phone must also be unlocked. See Apple’s eSIM guide or Samsung’s eSIM guide, or ask us.
