I forgot the password for my private messaging. How can I retrieve that?
Sorry! There is no way to retrieve the lost password. To continue using the Mr. SMS with new password, you need to wipe out all the current settings and data.

How can I remove/delete all the current database and create a new one?
Please contact us to get a database cleaner software to clean all the Mr. SMS's settings and data from your phone. This software is for free.
Warning:: Deleted data is unrecoverable.

Sometimes my scheduled messages are not sent. Why?
Mr. SMS is fully tested and no such problem related to performance is not reported yet. But if your scheduled messages are not sent please check.
1. Whether you have credit to send SMS in your account.
2. Autostart is enabled so that if the phone has been restarted before the scheduled time of SMS, it automatically send the SMS on next boot.

I have specified a rule in blacklist, but still the intended SMS comes in private messaging. How this could be possible?
Make sure that you have not created any rule in private messaging that in any way matches/conflicts with the rule specified in blacklist. Any received SMS is first matched against private rules and then against blacklist rules so most likely is the case that same blacklist rule in any other format is specified in private messaging rule list.
