In short: If your plan has not started, you can have your money back — including if you bought the wrong one or never travelled. Once the eSIM has connected to a network in its destination, the data has been bought from the local operator and cannot be returned. If a plan genuinely does not work where you bought it for, that is ours to fix. Refunding an order also reverses the cashback and referral credit it earned.
Language. This document is published in English, Azerbaijani, Russian and Turkish. The English version is the authoritative one: in the event of any discrepancy, difference of interpretation or dispute, the English text prevails and is the version that binds both you and MAMMADOFF AGENCY LLC. The other languages are provided for your convenience.
A plan that has not started can be refunded. A plan whose eSIM has already connected to a network in its destination cannot. A plan that genuinely does not work is our problem, and we will put it right.
The middle line is not fine print designed to catch you out, so here is the reason. When your eSIM attaches to a network, our supplier buys that allowance from the local operator on our behalf. That purchase is final — the operator does not take it back, and neither does our supplier. Refunding you at that point means refunding money we have already spent and cannot recover.
Everything below is that rule, applied to the situations people actually write to us about.
If your eSIM has never attached to a network in the destination, the plan has not started, no data has been drawn, and the allowance can go back to our supplier. Ask us and we will refund it.
That still holds in all of these cases:
Buying a plan does not start it. Neither does installing it. People often hold off installing until they land, worried about burning a day; you do not need to.
Connecting to a network at home does not start it either. Validity begins on the first attachment to a network in the plan's own destination.
We do not set our own deadline for asking about an unstarted plan. But our supplier will only take a plan back for as long as it stays unstarted, so if you know you will not use it, tell us sooner rather than later.
The moment your eSIM attaches to a network in the destination, the validity period begins and the allowance has been bought. From then on we cannot refund the plan, and these do not change that:
This is the exception to the section above, and we mean it. If you are in the destination, your phone is set up correctly, and you still cannot get a working data connection, write to us. That is not a cost you should have to absorb.
What we do: we check what the eSIM actually did. Our supplier reports whether it attached, which country and which network it attached to, and how much data it has drawn. That usually tells us within minutes whether the problem is the plan, the provisioning, or a setting on the phone.
If the fault is ours or the plan's — it was never provisioned properly, it will not attach at all, it was sold for a destination it does not in fact cover — we replace it or refund it, including when it has already started. If it is a setting, we will walk you through fixing it.
What we cannot treat as a fault: a patchy signal in one particular spot, a slow network at a busy hour, a building or basement with no reception, or one local network being worse than another. Coverage and speed belong to the local operator, and we neither control them nor can we improve them. If the plan is live and carrying data, but the network where you are standing is poor, that is genuinely not something we can refund. We would rather say that plainly than let you find out after a long email exchange.
Email [email protected]. There is no form to fill in and no queue to join — the message goes straight to a person.
Include these, so we can answer in one reply instead of three:
The request has to come from the email address the order was placed with, or from inside the account that owns the order. That is how we know it is you, and it is the only identity check we make you pass.
We are not going to quote you a response time. eSimUP is run by one person, there is no support rota and no ticketing system behind the address, and a target nobody is staffed to hit is worse than no target at all. What we will say is that a person reads every message, that we will not go quiet on you, and that if a case needs our supplier to answer first we will tell you so instead of leaving you waiting.
Refunds are also handled by hand. There is no button in the app that returns money, and no automatic process behind one — a refund is a person reading your message, checking what the eSIM did, and writing an entry to your ledger.
Where the money goes depends on how you paid:
This is the part that surprises people, so here it is plainly: if we refund an order, we also take back the credit that order earned.
Cashback credited on the order — at whatever rate it was paid at, currently 20% — is reversed. And if that order was the qualifying first purchase behind a referral, the $3 paid to the person who invited you and the $3 paid to you are both reversed, and the referral is marked void rather than rewarded.
We do this by hand. Nothing in the system reverses a reward on its own, so the reversal is a person writing a signed adjustment entry to your ledger with a reason attached — visible to you and to us. Your balance is the sum of the ledger, and nothing is quietly edited.
If you have already spent that credit, the reversal can take your balance below zero. We will not chase you for the shortfall and we will not send you a bill: it simply sits there and clears against the next credit that lands in your account. While your balance is negative you cannot pay for a plan out of it, because a purchase is refused unless the balance covers it in full. The same point is made in the User Agreement.
The logic is straightforward. Cashback is a share of a purchase. If the purchase is undone, there is no purchase to share. The same goes for a referral reward that was paid because someone made a purchase they did not, in the end, keep.
First, the state of play: you cannot top up yet. No payment provider is connected, so there is currently no way to add money to a balance by paying us. Paydo is the provider we intend to use. Everything in this section describes how top-ups will work once that is live, and nothing in it can have happened to you yet.
A top-up is not a plan, and this policy's refund rules will not apply to it. Adding money to your balance buys store credit, and store credit cannot be turned back into cash — it is not withdrawable and not transferable to another account. It does not expire while your account is open, so it keeps until you use it, but it stays credit.
So only top up what you expect to spend on plans. Bonus credit added on top of a top-up is likewise credit and not cash.
A top-up charged twice, or charged without your authorisation, would be a payment error rather than a refund question. Tell us and we will return it.
Reply and say so. Tell us what you think we got wrong, and a person will look at it again. We would far rather reconsider than argue.
Please come to us before going to your bank. A chargeback on an order whose eSIM has already carried data leaves us paying the local operator for data that was delivered to you, and while a chargeback is open we may have to suspend the account it relates to. Repeatedly using chargebacks in place of asking is grounds for closing an account.
Some countries give buyers a cancellation right on online purchases, and other consumer protections besides. Where a rule like that applies to you, it applies on top of this policy and not instead of it. If local law gives you more than this document does, local law wins.

Not legal advice. This document describes honestly how eSimUP works, but it has not been reviewed by a qualified lawyer and is not drafted for any particular jurisdiction. Before eSimUP takes money from customers it should be reviewed by a solicitor in the country the business is registered in — particularly the sections on liability, refunds and governing law.
