(2021-05-30) Texting failing

SMS texting works ok, but MMS, either for a group text, or for a single-person text with a photo attachment, is often unreliable. I'm pretty sure this has always been true, but can't find a record of it before today. (On t-mobile with Pixel 2 XL.)

Dec update: seems worse and worse. Trying to swap apps, but it doesn't help. (See twitter thread for some other "solutions".)

Mar'2022: even voice quality/connecting seems dicey these days. This pushes me to buy a Pixel 6.

Mar28'2022: have seen a couple failed-ends on SMS today, notice for the first time an "error 111" message. Apparently that's not new.

• Seems to only affect Pixel owners? Nope, here's a Galaxy Note-10 + Sprint case.
• a t-mobile-specific case
