    What our customers say about us

    If this service didn’t already exist – someone would have to invent it. We have been using sms77 for many years now and there has never been any problem. We had a reliable and smooth implementation into our customer database and just as reliable and smooth the messaging service does its job day after day.

    I have known seven for a very long time now and have used it in various projects and companies when it comes to reliably sending SMS. We use seven mainly for verification purposes as well as for transactional messaging. In every respect I can say: seven just delivers.
