My phone bricked a week and a half ago and I've been using a phone I walked into a lake on accident two years ago that still completely works except for cell service, so it only updates when I'm connected to Wifi now. I also have google voice number, so my texting works from that phone as well, but again only where there's Wifi. I'm going to make a claim, pay a deductible, and get a new proper phone at some point, but I've been a bit lazy and delaying it a bit because it hasn't been too bad going without. Although I did have one bad experience since it happened (almost immediately after). My car's battery died and it required me walking for almost an hour next to a dangerous street to get to some place that had Wifi and sort out getting my car towed and being able to open Uber to have someone pick me up.
