On most popular routes — yes, often significantly. But pricing varies by destination, data and duration, so the comparison table on this page reflects live values, not a marketing claim. For a handful of niche plans GigSky can be marginally cheaper; the 4% cashback then closes most of that gap on the first purchase, and tips Simsima ahead from purchase #2 onwards.

Every Simsima order — including discounted ones — credits 4% of the amount paid back to your SimCoins balance. 100 SimCoins equal €1, never expire, and can cover up to 100% of any future order. GigSky does not currently offer cashback or a comparable rewards system.

Simsima covers 190+ countries with active local bundles, plus regional and global plans. The country range is similar to GigSky's, with a small set of differences on either side — see the comparison table for actual prices in each destination.

Yes: a single QR code or Smart Link, working on every iPhone and Android device that supports eSIM. Average activation time after purchase is under 2 minutes. We back this with a guarantee — if the eSIM doesn't activate, we refund or replace it.

Simsima offers 24/7 chat support natively in 25 languages, run by humans rather than scripted bots. Average first-response time is under 5 minutes. GigSky's support varies in quality and language coverage.

You don't have to switch — many travelers keep both. But once you've used your 4% cashback once, the math compounds quickly. Try Simsima for your next trip with no upfront commitment; if you don't see the value you can keep using GigSky.
