Yesim vs RedteaGO: Which eSIM Should You Buy?
Updated September 18, 2026
The Short Answer
These sit at opposite ends of the same decision. RedteaGO is one of the cheapest per-GB eSIMs on this site, but data expires in 30 days and a top-up is non-refundable the moment it activates. Yesim costs noticeably more, but its Pay & Fly balance rolls over instead of expiring, and it backs purchases with a 30-day money-back guarantee that RedteaGO simply doesn't offer. Pick RedteaGO if price per gigabyte is what matters. Pick Yesim if you'd rather pay for a safety net.
Price Snapshot (before any code)
| Destination | RedteaGO | Yesim |
|---|---|---|
| United States | $2.00 (1GB) | $8.40 (1 day, Pay & Fly) |
| Turkey | $1.50 (1GB) | $7.70 (1 day, Pay & Fly) |
| UAE | $3.90 (1GB) | $7.70 (1 day, Pay & Fly) |
| Global | $31.00 (6GB) ≈ $5.17/GB | $20.90 (3GB) ≈ $6.97/GB |
These aren't quite apples to apples. RedteaGO sells a fixed GB bucket for a flat price. Yesim's country plans are priced by the day, not the gigabyte, through its Pay & Fly balance system, which is separately advertised as working out to roughly $1.10/GB once you draw it down that way. The Global comparison above is the closest like-for-like: RedteaGO still wins on raw price per gigabyte there too.

Is Yesim or RedteaGO the Right Pick
Go with Yesim if…
- You travel often and want a data balance that rolls over between trips instead of expiring
- You want a real refund option if your plans change and you don't use what you bought
- You'd rather pay more upfront for that flexibility than chase the lowest sticker price
Go with RedteaGO if…
- You want the lowest realistic price per gigabyte and are booking a single trip
- You're comfortable using the data inside a 30-day window with no refund on unused top-ups
- Hotspot and tethering matter more to you than a phone number: RedteaGO's FAQ confirms it's available everywhere it operates
Two Things Worth Knowing Before You Decide
The refund policies aren't close. Yesim advertises a 30-day money-back guarantee on unused plans. RedteaGO's own FAQ states data top-ups are non-refundable because the plan activates immediately once the purchase completes. If you tend to buy ahead of a trip that might change, that gap alone could decide it.
Neither is a real phone-number provider. Yesim is data-only across the board; voice runs over apps like WhatsApp or Viber. RedteaGO is data-only by default too, and only adds calls/texts on plans specifically labeled "Calls/Texts Available" or through a separate Call & Text package, not as standard. If a working phone number for calls or texts is the actual goal, see SimLocal instead, whose UK plans include one.

Yesim vs RedteaGO FAQ
Which is cheaper, Yesim or RedteaGO
RedteaGO, by a wide margin per gigabyte in every destination compared here. Yesim charges more for its Pay & Fly balance model, but backs it with a refund guarantee and a balance that rolls over.
Can I get a refund if I don't use the plan
With Yesim, yes: it advertises a 30-day money-back guarantee on unused plans. With RedteaGO, no: its own FAQ states data top-ups are non-refundable once the plan activates.
Which lasts longer before the data expires
Yesim. Its Pay & Fly balance rolls over between trips instead of expiring on a fixed schedule. RedteaGO's data expires 30 days after purchase.
Does either include calls or texts
Not by default. Both are primarily data-only. RedteaGO adds calls/texts only on plans labeled "Calls/Texts Available" or its separate Call & Text package. Yesim has no calls/texts option at all; voice runs over data-based apps.
Which is better for someone who travels frequently
Yesim, if the same balance carrying over between trips matters more than price. RedteaGO is built more for a single trip at a time, since its data has a hard 30-day expiry.
