Hi.
I have just come back from holiday in the states.
I decided to rely solely on xt's $10 roaming for the entire two weeks.
Despite my initial enthusiasm my experience quickly became very negative.
The main reason is the way roaming is provided.
Once you activate data roaming you get connected back to nz for all traffic.
This means you get tunnelled back to telecom nz and given an nz IP address.
So all traffic you generate becomes delayed by no less than 1 second.
These kind of packet trip times make effective use of internet (as in browsing let alone any attempt at voice skype) a complete farce. This is to a point of everything being slower than basic dialup, even when the network indicator shows hspa.
So. I've done it once but for any future trips i will be relying on local sims.
Nice attempts but execution very poor.
