So, at work, we get no cell signal at all. Due to this, my phone's battery life suffered because it would constantly search for cell signal. To fix this, I would turn Airplane mode on and then turn Wifi on. While that helped the battery life, another annoying problem emerged. Every time I opened Messages app, I would get the following popup. I don't have any texting plans so I just use iMessage. iMessage still works in Airplane mode (obviously, you have to have Wifi on). I started looking for solutions and finally found a forum (can't remember the name, sorry) where someone posted a solution that worked. I have pasted the solution at the bottom after the screenshot.
