2nd phone icon disappeared from my Nokia 730 after hard reset

[Michael in Paris]

I had to reset this phone due to increased problems.
After it rebooted, the phone and message icons for both SIMS were visibly pinned on the desktop (as before the reset) and both phones worked.
Now the phone icon for the 2nd SIM has disappeared both from the desktop and the menu, while the message icon for that second phone is still there.
The phone icon for phone 2 is not to be found in the menu, either where only the icon for the first phone is visible, and the 2 message icons.
I called that second number from another phone: it worked, I could reply, but when I disconnected, there was no trace of that phone on the Nokia. So in effect I cannot place calls from that SIM card.
How do I cause it to reappear?
Thanks.

I found by myself the solution: actually, the one icon that shows up is for both phones (this hadn't been the case before, so I didn't even know it could happen). By clicking on its options, there is one that allows to dissociate it into two icons, one for each phone, which I did.
