## How many GB for Thailand

| Usage | Our estimate | 3 days | 7 days | 14 days |
| --- | --- | --- | --- | --- |
| Maps and messaging | about 0.3 GB a day | 1 GB · £2.99 | 3 GB · £3.99 | 5 GB · £5.99 |
| Social media and photos | about 0.8 GB a day | 3 GB · £3.99 | 10 GB · £7.99 | 20 GB · £12.99 |
| Videos and video calls | about 1.7 GB a day | 10 GB · £7.99 | 20 GB · £12.99 | no single plan, take two |
| Working on a laptop (estimated data if your plan allows tethering) | about 3 GB a day | 10 GB · £7.99 | no single plan, take two | no single plan, take two |

Each cell shows a plan’s total data and price for that many days, not your use. Our editorial estimates, not measurements: HD video, background sync and backups, and sharing data as a hotspot all use more.

## Network and profile conditions

- Networks: True (5G), AIS (5G)
- APN set automatically
- Days count from the first connection to a network, not from payment
- Time to install the profile: 365 days after purchase

## A week in Thailand: your UK network vs eSIM

Roaming keeps calls and texts on your UK number; the eSIM is data only.

### Pay monthly

1.2× cheaper than paying for roaming.

5.6GB for 7 days (0.8GB a day, social media and photos) on pay monthly: what it costs on each UK network, next to the eSIM. “Included” means the network’s plans already cover Thailand within a fair use limit.

The sums assume data every day at 0.8GB a day, the same norm as the data calculator. We compare each network’s public roaming passes and daily rates. Some plans have roaming built in (for example Vodafone Global Roam, O2 Ultimate, Three Complete and Sky Diamond VIP), so check your own plan. Network prices as published for their own customers; the eSIM at its price in pounds on 31 Oct, charged in pounds by card. This site is not affiliated with these networks and is not their official site; we sell eSIMs.

## Frequently asked questions

### How much does a day of mobile data cost in Thailand?

On plans with a fixed data allowance, £0.13 to £0.43 a day in Thailand: 3 GB for 30 days at £3.99 is the lowest daily price, 20 GB for 30 days the highest. The plan that costs least for the whole trip: for 7 days, 1 GB at £0.43 a day; for 15 days, 2 GB at £0.27 a day; for 30 days, 3 GB at £0.13 a day. Unused days are not refunded.

### Which network does the eSIM use in Thailand?

Two partner networks: True (5G) and AIS (5G). The profile joins whichever is available; you don't choose the operator by hand.

### What if the eSIM doesn't work when you land in Thailand?

Check, in this order: data roaming is on for the eSIM line, the eSIM is chosen as the line for mobile data, and aeroplane mode is off. The APN sets itself on this plan, so leave it as it is. Give the phone a few minutes to register on True and AIS; that first registration is what starts the plan’s days. Still no connection? See [what to check when the eSIM has no signal abroad](https://esimworld.co.uk/help/esim-no-signal/).
