I put the settings into the app and tried connecting but it came up with ER05, invalid SIM card. I googled that and it I get leads to saying that the sim isn't authenticated for WIFI calling. I know that it is, because it works fine on stock roms. I've also attached a logcat of me attempting to connect. I've attempted to change some of the info of the strings to reflect my personal phone number but that did not change anything.
