On dvuhsimochnyh devices works only when you call on SIM card number 1. When you call on SIM card number 2 does not work. We need to fix it!

Original review

На двухсимочных аппаратах срабатывает только при звонке на симку № 1. При звонке на симку № 2 не срабатывает. Надо исправить!

I don't understand how this could be the case, but need to test to see if it's indeed a bug.

Had someone else with dual-sim confirm it works. There are no dual-sim specific issues we know of.
