Piranha Mobile Sim Card

I changed phone today and sim wasn't registering on network. I noticed on the sim toolkit that at the voice "subscription" it was selected on 1. I switched to position 3 and the phone locked onto signal in a few seconds. So my question is: how to know which selection is the best country by country? I like this sim and would like some help.
