SMS credits
2026-09-t156b-v1
1 credit represents 1 billed SMS segment, rather than one message. GSM-7 uses 160 characters for a single part or 153 per multipart message. UCS-2 uses 70 or 67 UTF-16 units; some characters take two units. The calculated number of segments is reserved before sending.
Packs of 100, 500 and 2,000 segments cost a final €7, €35 and €140 in EUR including applicable VAT. The tax breakdown is retained from verified tax evidence. Slovak and Czech phone numbers are supported. The activation bonus of 20 segments is recorded separately from purchases.
Purchased segments do not expire while the account is active. A definitive rejection releases the reservation; an uncertain result awaits verification without automatic retry or credit return. Undelivered messages may still incur a charge. Delivered status requires a verified provider callback.
SMS is not sent when credit is insufficient; email reminders continue. Topping up does not resend old SMS. One warning is sent below 20 segments, with another eligible only after a topup. A refund first blocks unused paid units. Bonus units are not paid out; account termination follows the agreed refund policy. New metering does not recalculate historical usage.
