I am having the following problem...

Sending SMS messages from my Jolla to my girlfriend's N9 does not always work. Once in few days, a message gets lost (is not received) even though on Jolla, the message status clearly says 'Received'.

Sometimes the message appears days later, after a reboot, even though many messages have been succesfully sent and received in the meantime.

I believe this is a problem of the N9 (database corruption?), but I couldn't find anyone with even a similar problem on this forum. Any advice would be very appreciated.

Thank you.
