I sent an SMS from Iran to a contact abroad, but the message didn reach its destination. Why?
If the receiver is on a supported network, then he / she received an SMS from SMSIran saying that a message had arrived at SMSIran. Then your contact must register at www.smsiran.com to be able to read your message. If no such informative message reached your contact, then we probably don’t support the destination operator at the moment. Please be patient as we’re working on this. Any progress will be posted on the site.
