Hello. I know that I have the most up to date iOS system but a few weeks ago I started getting notifications that I had a cellular service update available. Every time it would pop up I didn't have the battery and/or service I thought I would need to be able to do the update so I ignored it. I only got the update notification 3 times and it won't come back up. Anyone know how to get it to come back up? If so thanks in advance. I have a iPhone 5s.
That is the latest. Your phone must've updated without you knowing. Literally it takes a second or two it could've happened without you seeing it no reboot is required
