So I've been having this issue sporadically for months now, ever since I switched from an iPhone 7, to the iPhone X. At first I thought it was a phone issue since the problem usually happens when I'm on either my home or work wifi, and then leave - at which point the cellular data wouldn't function until a reboot the phone.
I've since done everything I can with my phone, wiped all the saved wifi networks, wiped the phone and installed fresh, etc. So now I'm turning to the problem being with Mint Mobile.
Has anyone else ever had this problem, or have thoughts on solving it?

@startech this solved my issues, https://www.reddit.com/r/mintmobile/comments/8phwn9/iphone_x_loses_wireless_data_within_24_hours/
it has almost been a week without a single issue. probably not the most official way to fix it, but works until Mint Mobile gives us better details to enter into the cellular settings.
