Sim card are activated only for one particular operator provider, selecting the other only means that the sim is not for the other one. In locations where there are plenty of providers you'll find as many as there are & being in manual you have to be certain which one. In automatic mode, it queries one after the other in round robin fashion until it gets an access. I've noticed that too, that different models of Nokia phone have diferent strenght of radio signals transmit/recieve. It's not surprising to to see one model have more bars (signal strenght) than others.
