The short version: buy an eSIM, install it, travel, enjoy. We'll do our best to keep you connected, you promise to use it sensibly, and if something goes sideways we try to make it right. The detailed rules are below.
These Terms of Service ("Terms") govern your use of the JamboSim website and our eSIM service, run by Goomla B.V. ("JamboSim", "we", "us"), a Dutch company (KvK 39101067) at P.J. Oudweg 5, 1314 CH Almere, the Netherlands. By creating an account or buying an eSIM, you agree to them.
1. What we actually do
We're a reseller of eSIM data plans, not a mobile network ourselves. The actual signal comes from local network partners through roaming agreements. Coverage, speeds and the technology used (4G, 5G, etc.) depend on the local operator and on your device.
2. Who can buy
You need to be 18 (or whatever counts as adult where you live) to buy an eSIM. Keep your account login to yourself, you're responsible for what happens under it. If something looks off, ping [email protected] straight away and we'll help.
3. Prices, taxes and payment
Prices on the site are in US dollars (USD) unless noted otherwise, and include any VAT we have to charge under EU rules. Whatever you'll actually pay, taxes and discounts included, is shown clearly at checkout. Payment is processed by Stripe. Currency-conversion fees from your bank or card issuer aren't on us, sadly.
4. How you get your eSIM
After payment, your eSIM arrives within minutes: by email, in your account dashboard, and (where supported) as a Universal Link or QR code. It's all digital, nothing gets shipped in the post. You install it yourself on a compatible, unlocked device, we have a guide for that.
5. Will it work on your phone?
eSIMs need an eSIM-capable, carrier-unlocked device. Please check our compatible devices page first. We can't refund situations where your device doesn't support eSIM or is locked to another carrier, see the Refund Policy for the details.
6. About signal quality
We'll do everything reasonable to make sure your eSIM works well. But no telecom on earth can promise a perfect, never-dropped, fast-as-fibre connection everywhere. Coverage maps are a guide, not a guarantee. Reception depends on the local operator, geography, weather and your device, things we genuinely can't control from Almere.
7. Fair use
Some plans have a Fair Usage Policy (FUP) set by the underlying operator. Cross the threshold and your speed might be reduced ("throttled") or the service paused for that period. Where it applies, the FUP is shown clearly on the product page before you buy.
8. Don't be that person
Use the service for lawful purposes only and follow our Acceptable Use Policy. If you seriously break the rules we may suspend or terminate the service without a refund. (We'd really rather not, but the network partners hold us to it.)
9. Auto-renew and subscriptions
Some plans support auto-renewal. Switch it on and you authorise us to charge your saved payment method for the next period before your current eSIM expires. Switch it off whenever, from your account dashboard, no penalty.
10. Refunds and the EU 14-day right
eSIMs are digital content delivered straight away, so the EU 14-day right of withdrawal expires the moment the eSIM is installed or activated (Article 16(m) of Directive 2011/83/EU, as implemented in Dutch law). Don't worry though, we still refund plenty of situations. The full breakdown is in our Refund Policy.
11. Our content
All the stuff on jambosim.com (text, logos, graphics, code) belongs to Goomla B.V. or our licensors and is protected by copyright and trademark law. Please don't copy, modify, resell or reverse-engineer it without asking us first.
12. The boring liability bit
To the maximum extent the law allows, our total liability for anything arising from the service is capped at what you paid us in the 12 months before the claim. We're not on the hook for indirect or consequential damages (lost profit, lost data, missed opportunities). Nothing here limits liability for fraud, gross negligence or anything else mandatory law won't let us exclude.
13. When we'd have to pause your account
We may suspend or end your account if you break these Terms, our Acceptable Use Policy or the law, or if a network partner or authority makes us. You can close your account whenever you like by emailing [email protected].
14. Changes to these Terms
We'll update these Terms occasionally. The current version always lives at jambosim.com/legal/terms. Anything material gets announced by email or on the site at least 14 days before it takes effect.
15. Governing law and disputes
Dutch law applies. Any dispute goes to the District Court Midden-Nederland (Rechtbank Midden-Nederland), unless mandatory consumer law sends it elsewhere. EU consumers can also use the European Commission's Online Dispute Resolution platform at ec.europa.eu/consumers/odr. Honestly though, please email us first, almost everything gets sorted with one message.
16. Customer reviews
We value genuine customer feedback. The reviews shown on our website are collected from our Google Business Profile and other verified platforms. Every review comes from a real customer who actually bought and used a JamboSim eSIM. We do not edit, filter, or hide negative reviews, the good, the average and the occasional grumpy one all stay up.
If you have purchased from us and would like to leave a review, we would genuinely appreciate it. After checkout you may also receive an optional invitation from Google to rate your experience.
Note: reviews reflect individual experiences and results may vary depending on device, destination and network conditions.
