Cheapest gigabytes, biggest caveat
Yesim in Greece
The best prices per GB on the Greek market, from the one provider whose Trustpilot score is currently suspended. You deserve both facts in the same paragraph.
The plans where Yesim wins
| Plan | Yesim | Next cheapest |
|---|---|---|
| 1GB / 30 days | $2.90 | GigSky $2.99 (7 days) |
| 5GB / 30 days | $11.13 | GigSky $10.79 |
| 10GB / 30 days | $18.54 | GigSky $18.29 |
| 20GB / 30 days | $25.50 | GigSky $35.49 |
| 30GB / 30 days | $32.45 | Saily 20GB $37.99 |
Below 10GB, GigSky matches Yesim within cents. At 20GB and above, nobody is close: the 20GB plan costs 33% less than the next option. That gap is why Yesim stays on this site at all.
The caveat in full
As of August 31, 2026, Trustpilot displays no score for Yesim: the rating is suspended for a guidelines breach, and the platform notes it removed a number of fake reviews. The reviews that remain skew positive but include recurring complaints about undisclosed throttling on "unlimited" plans and slow support.
Our read: the product works, the plans are real, and the network list (all three Greek operators) is the widest of our five. But a company that seeded fake reviews forfeited the benefit of the doubt, so we say it plainly instead of hiding the row. Buy Yesim for the price, with eyes open, and avoid their unlimited plans specifically: the fair-use cap is unpublished, and unpublished caps from a trust-deficit brand is a combination we do not recommend. For unlimited, Saily's published 5GB/day is the grown-up option.
Questions on Yesim
Is Yesim legit?
The service is real and delivers working eSIMs on all three Greek networks. The fake-review episode is about marketing integrity, not about whether the product connects. We treat those as separate questions and answer both above.
Why is Yesim so cheap?
Aggressive wholesale pricing and thinner margins at large bundle sizes. The 20GB and 30GB plans are loss-leaders by market standards, which is precisely where we recommend them.
Should I buy Yesim unlimited?
No. The daily cap is not published, and travelers report throttling they did not expect. Buy Yesim for fixed GB, buy unlimited from a provider that prints its cap.
