Not all contacts in group texts receive texts.

[Android Central Question]

I have four named groups with four contacts in each group. If I send to one group only, all contacts receive texts. If I send same message to all groups at perhaps 30 seconds to 1 minute intervals between groups, one or more contacts in each group do not receive text. All group texts show delivered. It seems the only solution is to wait 5 minutes or so between sends. I have had the same results using Textra, Google Massage, and Mood. Carrier is AT&T. Phone is Moto 4g plus.

The other thing to be aware of with AT&T is that ATT limits you to a very very small number of people in the group, something like 10.
