In case your use case is such that you have to send long text messages that go in multiple segments, here are a few things that you should consider:
SMS stands for Short Message Service. SMS allows you to send 160 characters per text. If your text is longer than 160 characters, it gets split into segments. You can read more on message length and segments here.
MMS stands for Multimedia Messaging Service. MMS allows you to send a multimedia message, including pictures and a text message of 1600 characters. You can get complete details on file formats and allowed file types here.
Which campaign is best for me?
1) If your text message is small and the list is not too long, you may send messages through a Text broadcast campaign.
2) If your text message is small but the list is too extensive, you should choose a Peer to Peer campaign with an adaptive texting block. This is required as carriers monitor all messages and tend to filter numbers based on various factors, some of which are discussed here. Adaptive texting block keeps track of filter numbers and rents a new number to ensure your campaign is not affected.
4) In case your message is more than five segments, and you wish to reach a large number of contacts in a minimum time, we suggest you rent a Shared shortcode or register for 10DLC to send messages from the Text broadcast campaign.
10DLC is a new messaging standard in the United States and we recommend you register yourself and use 10DLC to send messages to ensure you are not blocked by the carriers for sending messages from unverified numbers.
