SMS can be easily sent using our API with full status reporting and the ability to configure sender details (e.g. to set a Carrier number as sender to enable a reply). For coverage please see 'SMS coverage'.
SMS sent is charged against prepaid accounts and the rates can be found on our Ancillary Price List.
USD and EUR accounts will be billed at a rate derived from this one that adjusts for foreign exchange movements in-line with our voice rates.
