[Blocking Requested - why for this release]: a possible DUAL SIM scenario breaks one of the main functionalities.

Hi Marina. In general, the fix seems great to me but I left you a couple of nits on GitHub. We should simplify the test or increase its readability. I gave you some feedback on GitHub about this. Ask for my review when you finish to make the proper modifications.

Thank you and nice catch!
