Terms of Service | SimbaSIM

What you are buying, what it does, and what happens when something goes wrong. Written to be read, not to be survived.

1. Who you are dealing with

SimbaSIM sells prepaid mobile data plans delivered as eSIM profiles. These terms form an agreement between you and SimbaSIM (“we”, “us”). By buying or installing an eSIM from simbasim.com you accept them.

Company registration details are being finalised and will be published here. Until then, contact us at support@simbasim.comfor anything you would normally need a registered address for.

2. What the service is — and is not

You are buying mobile data only, for a set amount and a set number of days, in a set destination. That is the whole product.

There are no voice minutes and no SMS on a SimbaSIM eSIM. Calls and texts continue on your existing SIM and your own number. Apps that call over data, like WhatsApp or FaceTime, work normally.
You cannot receive SMS on the eSIM, so it will not work for receiving bank or two-factor codes. Those keep going to your usual number.
We do not operate mobile networks. Your data is carried by local network operators we buy capacity from, and coverage, speed and available technology are theirs, not ours.
No tethering restrictions from us: if your phone can hotspot, you may share the data.

3. Your device has to be able to use it

Before you buy, it is on you to check that your phone can install an eSIM. Two things commonly stop it:

Carrier locks. A phone locked to a network cannot add an eSIM. Your carrier can unlock it, usually for free once a contract is paid off.
Missing hardware. Older phones, and some models sold in mainland China, have no eSIM support at all.

If you buy and it turns out your device cannot install the profile, you are covered — see ourrefund policy. We would rather refund you than argue about it.

4. When your plan starts and ends

Your plan starts when the eSIM first connects to a network at your destination — not when you pay, and not when you install it.

This is deliberate. It means you can buy weeks ahead and install at home on Wi-Fi without burning a single day.

From that first connection, the plan runs for its validity period and then stops:

Plan	Data	Valid for
Cub	1 GB	7 days from first connection
Explorer	5 GB	15 days from first connection
Big Bear	20 GB	30 days from first connection

Unused data does not roll over and has no cash value once the plan expires. Plans do not auto-renew — there is nothing to cancel. If you run out of data before your days run out, you can top up.

5. Delivery

After payment we issue your eSIM and show it on screen immediately, and send the same QR code to the email address you gave at checkout. Getting that address right matters: it is how you retrieve your purchase if you close the tab. If nothing arrives within an hour, check spam and then email us — we can resend it.

Each QR code installs one profile, once. Once installed it is tied to that device and cannot be moved, reinstalled on another phone, resold, or transferred. Deleting the profile from your phone destroys the plan and does not entitle you to a refund.

6. Price and payment

Prices are shown in US dollars and include any applicable taxes where we are required to charge them.
Payments are processed by Stripe. We never see or store your full card details. An invoice is generated for every purchase.
Your bank may add a foreign-transaction or currency-conversion fee. That is between you and your bank; we do not receive it and cannot refund it.
Prices can change at any time, but never for a plan you have already bought.

7. Fair use

These are travel data plans for personal use. Speeds may be reduced by the local operator during congestion, and we may suspend or refuse service where use is clearly not ordinary travel use — for example permanent use of a short-trip plan in one country, commercial resale of the connection, or bulk machine traffic.

You must not use the service to break the law in the country you are using it in. That includes:

sending unsolicited bulk messages or running attacks against other networks or systems;
distributing material that is illegal where you are;
attempting to disguise the origin of traffic in order to commit fraud.

8. What we are responsible for

We are responsible for delivering a working eSIM profile for the plan you bought, and for refunding you when we cannot. If we get that wrong, our liability to you is limited to the amount you paid for the plan in question.

We are not responsible for things outside our control: network outages, a destination operator’s coverage gaps or speeds, your device or its settings, a carrier lock, missed flights, lost bookings, or business losses arising from being offline. Keep a fallback for anything genuinely critical — mobile data is not a guarantee anywhere in the world.

Nothing here limits liability that cannot lawfully be limited, including for fraud.

9. Changes, and ending things

We may update these terms; the version in force is the one published here on the day you buy, and the date at the top tells you when it last changed. Material changes will not be applied retroactively to plans already purchased.

You can stop using the service at any time by deleting the profile. We may suspend access where these terms are broken, or where we are required to by a network partner or the law.

10. Governing law

These terms are governed by the laws of the United States. If you are a consumer, this does not take away any protection you have under the law of the country where you live.
