Been trying to work out if I need to buy a US sim or not - my iphone 4 is unlocked so I can put a US card in it - but I am not intending to ring home more than a few times.
I know I will want to use it for Line queues etc but am I confused - if I keep my own Tescos card in the phone - switch data roaming off - will I be able to access the Free Wifi in the parks or do I need a US Sim for this .
Also if we had free wifi working would we then be able to message each other by using an internet based messaging package.
Sorry for all the questions - been trying to read all the ebay card sellers pages but ended up more confused :-)
Hope someone can help
