What Network to use in Philippines

The OP asked what network they will connect to.  I was expanding on that and asked them if they knew which one they connected to.  Right, many (all?) providers who have intl agreements will try to make the connection as transparent as possible. That doesn't automatically translate to 'no fees' and other promises; there's a lot of words in those agreements you click 'Accept' on.  If I remember when I'm back I'll post my experience.  BTW, Congstar is a T-Mobile MVNO in GE and it's subcarrier is ja! mobil which works just fine in US.  GSM for all!

I don't believe you can select specific carriers. In some countries I've seen multiple carriers depending on which city I am in and what time of the day it is. If you want to lock into a specific carrier, you would need a SIM card from that carrier and your TMO phone needs to be unlocked.
