1430 SMS bug on Z30.

My father's Z30 gets an SMS from 1430 after rebooting his phone. When he opens the SMS it reads: "You have a message to recover. Press click on the following button to download it. - Download now"

When you click on it, a further message indicates the SMS could not be recovered.

No matter that it gets erased, it always comes back after any reboot, so it's quite annoying.

Any input and fix on this bug, short of doing a factory reset?

As it appears on the Hub.

Try to remove sim card and restart phone and see if it dissappear.
