The long way round
- Your phone connects to a tower where you are.
- The data travels back to the carrier's network in the United States.
- It goes out to the internet from there.
- Then it comes all the way back the same way.
Most US carrier plans route roaming data through their home network: a foreign tower, across to the United States, out to the internet, then all the way back. The delay is built in, and so is the day-pass charge.
