Who I have the same questioned this topic

Apparently on 9 February 2022 Verizon made some type of change to the 3G network such that regular text messages fail to send.  I receive a generic message that text failed but the message info states “No SVC” for “Transport:” and “Temporary (Network Problem:Ntwk.Fail.) for “Cause Code:”  or a transport code with no cause.  I went through Verizon trouble shooting with no success and was going through chat help when my connection dropped.  On a whim, I tried a picture message and it works but still no luck with regular text messages.
