Some idiots decided to blow my phone up by mass SMS with 20 participants, which are delivered via MMS. I tried to reply but every message failed to deliver and the Hangouts app says "Message not sent. Touch to retry."
I am able to SMS single numbers and MMS with a few people, but haven't had the chance to test how many it takes to break outgoing messages. Is there an official supported limit from T-Mobile somewhere?
Phone is Nexus 4 on 4.4.2
