Depends on where he is and if he is stationed or deployed. For example if he is on a MEU deployment where he is on a ship then no texting or calls from the cell phone unless he is in port and then there will be roaming charges unless he gets a local calling card. There could be a phone on ship but those are usually $2 a minute. If he is deployed to a place like Afghanistan, then maybe but it will be costing a lot. He can call you from the phones there but it is not going to be all the time. If he is stationed in a place like Japan then he will have to get a local carrier.
