Selecting SIM card on dual sim phones

[sphh]

If you use a phone with two SIM cards, the Select a SIM for this call dialog box is displayed often. On my phone, the two lines are close together, so I already tapped the wrong line by accident a couple of times.

The dial pad has a SIM card selector at the bottom. Would it be possible to implement a similar one for the Select a SIM for this call dialog?

In the dial pad I like that the icon for the primary card is displayed in a bigger style. I also like that the phone numbers are displayed in the Select a SIM for this call dialog, but if that is not possible, I would prefer the different icon sizes.

I could also think of using the whole available screen space split into two: Tapping anywhere in the upper half would use the first SIM and in the bottom half (which could be smaller) the second SIM.

On my phone I can also set the colour for the two SIM cards (Settings > Network & Internet > SIM cards). Maybe these colours can be used for the two icons?

What do you think?
