Since Android 14 introduced stricter policies regarding SMS handling in work profile mode, including limitations that affect the use of SmsManager, developers are facing challenges in maintaining SMS functionality.
If you're open to using an alternative approach, SMS Textr could be a viable solution. It is a cloud-based, pay-as-you-go SMS API service designed to work independently of the device's native SMS functionality. This makes it immune to Android's restrictions in work profile mode.
