In years of using GV, group texts never worked correctly for me, and generally broke in unpredictable ways - some recipients would get some msgs, others would get other msgs, and others might just get dropped entirely. It was both weird and completely untenable for anything even remotely important.

Yes, remotely important business does get conducted via group text once in a while - is it ideal, probably not, but I meet companies/individuals I work with where they are in the mutually easiest format. That only works if I can rely on the SMS solution in the first place, though.
