thanks; if making few calls, can I also ask T-mobile to enable international roaming and use my t159 as is?

First, make sure that your phone are unlocked. Second, when you get to your destinations, buy a SIM card to put in your phone. You more than likely will easily be able to find a service right inside or outside the airport. Then you just have to get your new numbers to eachother

New here, not sure where to ask this. We are in our 70s, have Samsung t159 phones with T-mobile. I am going to England and Italy, then back to England. Wife will join me in London. What are our options for making cell-phone contact with each other or for making local calls while there?
