Exclusive eSIMKart code from JamboSim (2026-10-26): 10% off, no expiry, reusable by the same customer.
JamboSim's ESIMKART10 code takes 10% off your JamboSim eSIM order, and unlike most codes in this series it isn't limited to your first purchase: you can use it again on later orders. It's exclusive to eSIMKart, and every figure below is read live from the same database that prices every plan on this site.
What JamboSim Actually Offers
JamboSim (run by Goomla B.V. in Almere, the Netherlands) lists 2,040 active plans on eSIMKart: 1,829 single-country plans in 196 countries plus 211 regional plans, which together reach 203 destinations. Plans run from 1 day to a full year (365 days), and prices start at $1.99.
The regional range is where JamboSim stands out. There are 15 bundles: Europe (41 countries), Europe + UK, the Balkans (10 countries), Scandinavia, Asia, Southeast Asia, Oceania, North America, Latin America, the Caribbean, the Middle East & North Africa, Africa, a three-country East African "Safari" plan, and two global plans covering 192 and 165 destinations. If your trip crosses borders, one eSIM can cover the whole route.

Where JamboSim Fits
JamboSim's Unlimited plans are fair-use plans: you get 3GB of high-speed data per day, then the speed drops to about 1 Mbps until the day resets. That's enough for maps, messaging and browsing, but not for streaming video all day. If you need more than 3GB at full speed every day, a large fixed-data plan is usually the better buy. Not sure how much you need? Our travel data calculator gives a quick estimate.
Every JamboSim plan includes hotspot/tethering, and you can top up an existing eSIM from your JamboSim account without reinstalling it. Plans are data only: no phone number, calls or SMS. Plan validity starts when you activate the eSIM, not when you buy it.
How to Actually Use the Code
Add a plan to your cart on JamboSim, click "Have a discount code?" and enter the code shown in the discount card above. The 10% comes off the order total before you pay. The code has no end date set and you can use it again on later orders, so there's no need to save it for one big purchase.
