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 Ubigi 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 credits 4% of the amount paid to your SimCoins balance, except orders that use a partner promo code. 100 SimCoins equal €1, are valid for 12 months, and can cover up to 100% of any future order. Ubigi does not currently offer cashback or a comparable rewards system.

Simsima covers 190+ destinations with local plans, plus regional and global plans. The range is similar to Ubigi's, with a few differences on either side: see the comparison table for actual prices in each destination.

Yes: a Smart Link (one tap on Android and on iPhone with iOS 17.4 or later) or a QR code, on every iPhone and Android device that supports eSIM. Installation takes under 2 minutes, and the eSIM activates when you land. If it won't install or connect, contact us and we'll fix it or refund you.

Simsima's support is run by real people, not scripted bots, and we usually reply within 24 hours. Ubigi'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 Ubigi.
