You can activate the roaming and call to UK from USA or swap to a USA network and call UK to cut down the roaming cost.To do this, the phone should not be locked to any network.If it is locked, you need to unlock it, using service provider or third party unlock service like unBBlock.com (for Blackberry) or Simpleunlocking.com (other mobiles) and unlock the mobile.Once unlocked you can swap to USA networks and call UK and thus cut down the roaming cost.
If you have a world phone, you should have more than one slot for a data/sim card. You may buy a sim with a provider in the States, and set up an International plan, for while you are here to call home.
Just place the sim card in the other slot. You can only have one active at a time, so just turn off the European one, while here. Make sure you save your contacts list to your phone, so that regardless of which sim is active, you have access to your contacts list in the phone.
If you only have one sim card slot, when you get here... get a compatible sim card. If your phone is a CDMA and has no sim cards, buy a Tracfone for cheap, and get an International call package.... Hope this helps.
