Tired of watching your long SMS messages get split into weird chunks? We are too. That’s why SignalWire now supports sending long text messages as a single MMS — no more guessing where your message will get cut off.

When set to true, this parameter forces the message to be sent as an MMS, even if the message body contains only text.

  1. cXML: use the SendAsMms parameter

  2. RELAY: use the send_as_mms parameter

Reduce friction and gain better control over your message formatting by delivering long messages as a single MMS payload. Just another reason why SignalWire's programmable communications platform is better than duct-taping features together.
