Can somebody give an advice on how can i use the remaining sim slot 2 & 3 on my E700 Acer phone... it doesn't work out on another simcard network.  Currently i'm using Sun Cellular Network on Sim slot 1, but when i decided to put another simcard like Globe sim network, it doesn't workout though i already activated it on settings.  Please share some advice.  Thank you.
