and didn't even notice it, until this morning. Had to call 611 (then 800-331-0500 since the problem was with my iPhone I had to call on my landline) and have them walk me through it. They had me turn the iPhone off, take out the battery (applies only to non-iPhones), and take out the SIM card; then put everything back and turn the iPhone back on. They told me to hold on while they did some updating on their end, and then I received a text message from them, telling me "do not respond" and everything seems OK. My son hasn't followed the procedures yet, since he is in the field and unable to take my call. It was weird because "all" four phones were unable to send/receive text messages since last night. Anyway, anyone else going through the same?
