Transparent and fair – Prices to send SMS

Simply top up your credit balance and pay only the SMS you send. There will be no additional costs for you. All features like the API, Email2SMS etc. are available free of charge for each account.

*All prices are subject to value added tax at the statutory state. Prices for non-EU countries may vary. Please check our full price list by country. The prices are valid for a sent SMS with 160 characters. Messages with more than 160 characters are calculated according to the number of sent SMS, in which for each SMS message 8 characters less are available. An SMS with e.g. 310 characters would thus be calculated with the triple SMS price. For SMS with unicode characters, ie characters which are not included in the standard GSM alphabet (e.g. cyrillic, arabic, etc.), only 70 character per SMS are possible. The price is then for 70 characters. No transmission to special call numbers.
