One payment, from before you press the button to after.
Last updated 21.09.2026
Accepted
Visa and Mastercard credit and debit cards. No other payment method is accepted, and there is no bank-transfer route for adding credit to a family pool.
We accept
Online card payment is not open yet. The payment button in the console is disabled and says so, and nothing can be charged. This policy describes how payments will work once it opens.
01 · Before
What you are buying
Prepaid credit
A payment adds prepaid credit to your family pool. It does not buy a plan or a period of service, and nothing renews. The credit does not expire, and you use it to get a SIM for someone in your family when they need one.
Who can pay
Individuals and businesses. A business may pay for eSIMs for the people it sends travelling, or for an employee's family on a trip. Payments are made by the organiser: the adult who holds the account. Someone who pays on behalf of a business confirms they have the authority to bind it. eSIMs and credit may not be resold.
Amounts
Any amount from €1.00 to €20,000.00 in one payment, or the same amounts in US dollars, or one of the preset amounts: €25.00, €50.00, €150.00. The console shows the exact figure on the button before you press it.
Currency
You pay in the currency you choose: euros or US dollars, from the switch at the top of any page. The pool holds credit, and one credit is one euro; a payment in dollars buys credit at that day's exchange rate. The figure on the button is the figure your card is charged.
02 · At the moment
What happens to your card
Your card details
You enter them in the console. They are sent once, over an encrypted connection, through our server to the card processor to take this one payment. We never store them, log them or keep them for next time, so every payment needs the card entered again.
Your bank's check
Your bank may ask you to confirm the payment (3-D Secure). Credit is added to the pool only once the bank has approved it.
Pressing twice
If the same payment is submitted twice, it is recognised and you are not charged a second time.
03 · After
What you receive
An approved payment
The credit is added to your family pool straight away, and the pool's history shows the amount and the balance after it.
A declined payment
Nothing is added and nothing is charged. The console tells you the payment was declined.
A payment you question
Write to billing@perdiem.tech first, and we will look at the payment with you. This policy does not restrict your right to dispute a payment with the bank that issued your card.
Payments are received by Tsernskin keiys OÜ, a company registered in Estonia (registry code 17587191, registered office P. Kerese tn 17-20, 20309 Narva, Ida-Viru maakond, Estonia). What happens to money already in the family pool, such as unused credit, a mistaken payment or a SIM the provider could not issue, is set out in the refund policy. How to stop using the service is in the cancellation policy.
