Hello & Welcome to JustAnswer.
Thank you for your question. I will do my best to assist you. My name is Jamie.
What kind of phone do you have?
Sometimes this can be becuase wifi calling in on. Trying to see where to find it on your phone. Needs to be turned off.
go to settings, and then phone
do you see Wi-Fi Calling ?
restart your phone now that you have it off
what network are you using with this phone?
Try going to settings , then about phone, then System Updates. If an update is available, follow the instructions on your phone to download and install it.
There have been some known bugs with moto x getting stuck in airplane mode.
Ok, let me know if you want to try something else if the last thing doesn't work.
Next step would be to reset the phone entirely. Will wipe all the data from the phone, but at least might make it useable.
I would suggest doing a backup before doing the below steps if you have anything important on the phone.
1. go to Touch Settings
2. Touch Backup & reset3. Touch Factory Data Reset4. Touch Reset Phone
