Unable to Send SMS programmatically in Android for some devices

Question

In our app, we are trying to send SMS progrmmatically. For 20% devices app is not able to send SMS. We are getting "RESULT_ERROR_GENERIC_FAILURE" error from sms receiver in most cases and in most cases sms is not being sent from device itself.

Below is the code snippet we are using for sending sms.

private fun sendSms(subscriptionId: Int, number: String, smsText: String, sentPI: PendingIntent?, listener: ISmsSendListener) {
    try {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
            SmsManager.getSmsManagerForSubscriptionId(subscriptionId).sendTextMessage(number, null, smsText, sentPI, null)
           
        } else {
            SmsManager.getDefault().sendTextMessage(number, null, smsText, sentPI, null)
          
        }
    } catch (e: Exception) {
        e.printStackTrace()
    }
}
