Terms of service

Who we are

SefereSIM sells prepaid travel eSIM data plans. A plan is mobile data, delivered as an eSIM profile you install on your own phone and use on local networks at your destination. It is data only: no phone number, no calls, no texts.

SefereSIM is a brand name of Vigilainte Inc., not a separate company. Vigilainte Inc. is incorporated in Delaware, United States, and its registered address, which is also the address to write to, is 8 The Green, Ste D, Dover, DE 19901, United States. If you see either name, on a receipt or on a card statement, it is us.

In these terms, "we" and "us" mean Vigilainte Inc., and "you" means the person buying a plan.

What you are buying

• One purchase, one tripUnless a plan says it renews, it is a one-time purchase: nothing renews, and there is nothing to cancel later. The plans that do renew say so on the page, say so again at checkout, and are governed by "Plans that renew" below.
• The price you seeThe price is on screen in US dollars before you pay, and that is the amount we charge. If your card is in another currency, your bank sets the rate and may add a fee of its own.
• What a plan includesThe data volume and the number of days shown on the plan, on the networks our supplier reaches in that country.

Plans come and go as our supplier changes them, so a plan you saw yesterday may not be on sale today. The plan and price you confirm at checkout are the ones we are bound by.

Plans that renew

Some plans are sold as a subscription. You pay for one period at a time, and the next period is charged to the same card automatically until you cancel. There are two lengths: every 7 days, or every 30 days.

It is counted in days rather than in months. A 30-day plan buys 30 days of service and is charged every 30 days, so it does not land on the same date each month, and over a year it comes round a little more often than a calendar month would.

The price you agree to when you subscribe is the price we charge each period, in US dollars. If we change what a plan costs, the new price is for people who subscribe after the change. Yours stays where it is until the subscription ends.

What arrives each period depends on the plan. A data plan tops the same eSIM up automatically, so there is nothing new to install. For an unlimited plan, a supplier-supported validity top-up extends the same eSIM without stacking or changing its daily high-speed limit. If the installed profile does not offer a compatible top-up, that period arrives as a fresh eSIM to install. Either way we email you when the new period is ready.

You can cancel at any time, from the billing section of your account or by writing to support@seferesim.com. Payments, the card and the cancellation are handled by Stripe, so the card is held there and not by us, and the billing page is where you change it, see what you have been charged, and stop the subscription. Cancelling stops the next payment. It does not stop the period you are in: that one is paid for, and it runs to its end.

A period that has started is not refunded. Cancelling stops the next payment rather than buying back the days you are already in. Apart from that, the refund policy applies to a subscription exactly as it applies to any other plan: an eSIM that never activated or does not work is the one exception, and it is the same exception whether it arrived on the first period or the tenth. None of this removes rights you have under the consumer law that applies to you.

If a renewal payment fails, nothing is cut off. The period you have already paid for keeps working, Stripe tries the card again, and we write to you once so you can update it. If no payment goes through, no new period starts, and the subscription stops at the end of the period you paid for.

The 14-day withdrawal right works here the way it works on a single plan, and the tick box at checkout is the same one: it takes effect when the eSIM is activated, and until then the right stands. If you subscribe and change your mind before that, write to us within 14 days and we will cancel the subscription and return the payment. After that, cancelling is what stops the next one, and it can be done at any time.

One thing we ask of you rather than of ourselves: the country promise in "Where we cannot sell" has to stay true for as long as the subscription runs, and not only on the day you subscribe. We check it when you subscribe. Nobody checks it again on your behalf when a period renews, so if it stops being true, cancel.

When the service starts

Your plan starts when the eSIM first connects to a network at your destination. It does not start when you pay, and it does not start when you install it, so buying a few days early costs you nothing.

Once it has started, the validity runs continuously to the end of the days shown. Those are calendar days, not days on which you happen to use data.

Your phone, and installing

An eSIM installs on one phone, once. Deleting the profile from that phone uses it up: it cannot be installed again, on that phone or on any other, and any data left on it is lost. That is how eSIM works everywhere, and it is not something we can reverse.

We ask which phone you have before you pay, and if that phone cannot take an eSIM we say so and sell you nothing. The install itself happens inside your phone settings, where we cannot see it, so we can tell you what to tap and no more.

Where we cannot sell

A few countries are under trade sanctions wide enough that neither we nor our supplier may sell into them. We do not take orders from those places, and we cannot make an exception for one trip.

When you buy, you are telling us three things: you are not in one of those countries, you are not buying for someone who is, and you are not a person or a business named on a sanctions list.

Checkout stops those orders before any money moves, so most of this you will never see. If an order does get through and we find out afterwards, we cancel it and refund you, and that is the one refund we give without first checking whether the data was used. If the sanction itself stops us from returning the money, we say so and tell you where the money sits.

Using the service

Use the data lawfully, on the phone you installed it on, the way a traveller uses a mobile plan.

• Follow the law of the country you are in, and the local operator terms that apply on their network.
• Do not resell the plan, run it as a commercial connectivity service, or leave it as a permanent line for equipment.
• Do not use it for anything a network operator would treat as abuse, such as bulk unsolicited messaging or attacks on other systems.

Local operators can suspend or block a line themselves, and when they do we cannot bring it back.

We can stop or suspend a plan for a short list of reasons: use that breaks the rules above, payment fraud or a stolen card, an instruction from our supplier or a local operator, or a legal or regulatory order we have to follow. Our supplier also watches for patterns it calls abnormal, and it is worth knowing what they are: a line that burns most of its data in a very short window, a line that sits in one country for months instead of travelling, a line living in a router rather than a phone. It can act on those without telling us first, and we cannot reverse it.

We only do this where the reason is real and the response is proportionate. We tell you the reason when we have it, and we say so when we do not, because our supplier is not obliged to explain itself to us either. If you think the decision is wrong, write to support@seferesim.com and a person will look at it again. A plan we stop because the rules above were broken is not refunded. A plan stopped for any other reason is treated the way the refund policy treats a plan that does not work.

Refunds

We do not refund a plan once it has been used. The one exception is an eSIM that never activated or does not work. The refund policy is a page of its own, and it is part of these terms.

Your account

You need to be 18 to buy from us and to hold an account. If you are younger than that, the purchase has to be made by someone who is not.

Buying creates an account. It is where your order history lives, and it is the login the iOS app uses. Keep the email address on it reachable: that is where the eSIM is sent and how we reach you when something needs a person.

The account is yours to guard. Keep the password to yourself, and write to us as soon as you think someone else is in it, because until you do we cannot tell your orders from theirs: an order placed through your account is an order we treat as yours. Tell us early and we will stop whatever has not been delivered and go through the rest with you.

You can delete the account from the iOS app, or by writing to support@seferesim.com. Order records outlive the account, because we are required to keep them. The privacy page says exactly what stays, and for how long.

If you use the iOS app

Plans are bought from us, on this site or in the app, and paid through Stripe. They are not App Store purchases, so Apple does not take the payment and cannot issue the refund. Refunds come from us, under the refund policy.

The agreement for the app is with us and not with Apple. Apple has no duty to support or maintain it, and nothing you buy from us is Apple’s to answer for: not a claim that the app does not work, not a product liability claim, and not one under consumer or data protection law. If the app infringes someone’s intellectual property, that is ours to defend. Apple and its subsidiaries can rely on this section and enforce it against you, which is a condition of being in the App Store rather than a change to who you are dealing with.

Apple also requires the country promise that the sanctions section above already asks of you. It is the same promise, not a second one.

What we are responsible for

We are responsible for delivering what you paid for: a working eSIM profile for the country, the data and the days shown on the plan. When we cannot deliver that, the refund policy says what happens.

We are not the network. Coverage, speed and outages belong to the local operators our supplier buys from, and we do not control them.

We do not set the speed either. Operators and our supplier manage traffic to keep their networks standing, which can mean slower data at busy hours or after heavy use, even while your plan still has data left on it. The volume and the days are what we sell you. The speed at any given moment is not something anyone in this chain can promise.

If something does go wrong on our side, our liability to you is limited to the amount you paid for the plan in question. We do not cover indirect losses, such as a missed booking or a cancellation fee.

Some things stop the service that nobody in this chain chose: a network-wide outage, a regulator switching something off, a country blocking traffic, a war, a disaster. We do not owe you damages for those. We do still owe you the plan you paid for, so where one of them means we cannot deliver it, we refund it on the same terms as an eSIM that never worked.

Nothing here removes rights you have under the consumer law that applies to you.

What you are responsible for

This is the mirror of the section above. If you use a plan in a way these terms rule out and that costs us money we would not otherwise have paid, we can ask you for it. That means a third party’s claim, a fine or a charge our supplier or a local operator passes down to us, and what it reasonably costs us to deal with either of those.

It is deliberately narrow. It covers unlawful use, resale, and breaking the country promise above. It does not apply to an ordinary complaint about a plan that did not work, it does not touch the consumer rights the next sections protect, and it does not turn our own limit around: what we owe you is still capped at what you paid for the plan.

Changes to these terms

We can change these terms for future purchases. The version in force on the day you bought a plan is the version that governs it, so a change later does not rewrite an order you already placed.

Law, and where disputes go

These terms are governed by the laws of the State of Delaware, United States, and a dispute we cannot settle between us goes to the state and federal courts located in Delaware.

That choice does not take away consumer rights you cannot be asked to sign away. If you are a consumer resident in the European Union, the United Kingdom or Türkiye, you keep the protections that the law of the country you live in does not allow us to contract out of, and you can bring proceedings against us in the courts of that country. If we ever have to bring proceedings against you, we bring them there too.

Write to us before you escalate anything. Most of what reaches a dispute would have been quicker to fix by email.

A few last things

• These terms, the refund policy and the privacy policy are the whole of what you agreed to. Something we said in an ad, a help article or an email does not change them.
• If a court finds one sentence here unenforceable, that sentence goes and the rest stands.
• If we do not enforce something straight away, we have not given it up.
• We can transfer this agreement if the business is sold or reorganised, and your plan and your rights travel with it unchanged. You cannot transfer a plan to someone else, because an eSIM cannot move phones.
