FAQ & TERMS

FAQ & Campaign Terms

Is it okay if this is my first time using eSIM?

Setup is just 3 steps. From setup before you leave to connecting once you arrive, you can get help in English if anything is unclear.

When should I do the setup?

Add the eSIM before you leave, and switch your mobile data line to the eSIM once you arrive at your destination. Setup steps and the right timing vary by device and OS, so please check the TRAVeSIM How-to page.

Am I guaranteed a refund if it doesn't work?

No, this isn't an unconditional refund. It's subject to review if you meet the campaign's eligibility conditions — the required settings check and screenshot submission, and confirming your data usage is zero.

Will I still get a refund if it shows as activated?

Regardless of whether it shows as activated or not yet activated, it's eligible for review as long as the data usage we can confirm on our end is zero. You still need to meet the other eligibility conditions.

Which screenshot do I need to submit?

Once you contact us to request a refund, our support staff will tell you which screenshots to submit.

Can I apply after I've returned home?

You can contact us as long as it's within the validity period of your eSIM plan, but once it expires we can no longer confirm data usage, so it becomes ineligible for a refund review. You'll also need to submit a screenshot of your settings screen. So please contact us as soon as you notice you can't connect, while you're still on your trip (within the validity period of your eSIM plan).

Can I combine a coupon with the multi-purchase discount?

No, coupons can't be combined with it. That said, an eSIM purchased with a coupon is still eligible for review under the full refund campaign if it meets the eligibility conditions.

What if only one of several eSIMs I bought doesn't work?

Only the eSIM(s) that meet the refund conditions are eligible. We refund based on the actual amount paid for the eligible eSIM(s) after the multi-purchase discount is applied.

What currency is the refund issued in?

Refunds are issued in the original payment currency. Credit card payments are refunded to the card used for purchase, while PromptPay payments are refunded to a Thai bank account. Due to exchange rate differences at the card company, the charged amount and refunded amount may not match.

How many days does it take to receive the refund?

Reflecting the refund can take about 1–2 months for credit cards, or about 1 week for Thai bank account refunds.

Am I still eligible if I've deleted the eSIM?

Yes, it may still be eligible for review if our records show zero data usage and all other campaign conditions are met. However, because a screenshot of your device settings is required, we recommend contacting us before deleting the eSIM whenever possible.

Am I eligible if I couldn't connect because of a local network outage?

Yes — if there was no issue with your settings and you couldn't connect because of an outage on the local carrier's end, it's still eligible for review as long as your data usage is zero.

Where do I apply for a refund?

Please contact us via our official LINE account.
