I do this at home to avoid needlessly hunting for towers that are barely in range. But I am concerned that if I don't leave the house for a few days the carrier (Google Fi / TMobile) may be discarding messages. I've heard mixed opinions on if this is happening. But I am missing calls even with WiFi calling on.
