We had the older version Go-Sim with Estonian number and just upgraded to the newer technology. The customer service was great, and they moved our old balance to the new cards which are much faster so it doesn't feel as much delay as old ones. Also like that you get both USA and UK numbers. We'll decide when we return if my husband even needs any other phone while in USA.
Only downside is the shipping costs are expensive.
