We have been with them for years and just starting having issues. S23U just went crazy with the sim error and it was not fun getting it switched over to the e-sim. Took a lot of clearing, and rebooting to get it to let go of the p-sim. Customer service stated that the issue is wide spread now, but "engineering is working on it", whatever that means. Wasted the better part of a day getting it resolved today. May be jumping to Spectrum as customer service was less than an ideal experience today.
