Length limitations are not an issue because UTM will automatically split up long messages while intelligently maintaining readability by ensuring that partial words are not left at the beginning or end of message segments. Other features like multiple recipients and message personalization per recipient make UTM a powerful library that will save any developer a lot of time and frustration. The word “umbrella” in the name is used in the same manner as the phrase “umbrella term.” UTM supports multiple SMS gateways, but only a few gateway-specific options keep the interface from being completely universal. The same methods are used regardless of the choice of gateway, so the code for sending a message with one gateway can easily be adapted to use another gateway instead if your needs change.
