I too have been having issues with sending single and group texts. There's a long delay or it just simply fails to send. T-Mobile support has had me already do the following;
- Clear the messaging cache.
- Remove my SD card.
- Reboot into Safe Mode (I only use the default apps).
- Update Network Connections.
- Clear my texts.
- Factory reset.
I always seem to have 4 or 5 bars on my antenna (LGV30). Nothing seems to be fixing this issue.

Welcome to our Support Community! It sounds like you've almost done everything possible on your end to get texts sent. Are you having any issues receiving texts? When did this start (ex. randomly, after an update, etc.)? Have you filed a ticket with Tech Support yet?
We'll do our best to iron out why this is happening!
