    There is no such specification. It is solely up to the provider. For example, T-Mobile and ATT both state 100MB on their “Advanced Messaging” FAQ. I’m sure Verizon is the same though I couldn’t find the exact wording.

    The spec does state there is an 8,000 character limit and a maximum of 100 participants in a group conversation.
