Oddly, I was talking to a mate at work yesterday about USA phonecalls on my [Only registered and activated users can see links. ] which gives you a Global mobile out of the box for international roaming but also gives the option to get a USA mobile number. There's a premium to them and my mate, who goes on his hols there almost every year, told me he just bought a payg phone over there and that most deals include international calls as well as whatever talktime etc you buy. Probably worth looking at US providers if it could be a regular thing.
Other than that, 3 have the 'Feel at Home' deal that uses your inclusive allowance in a few countries including the USA. [Only registered and activated users can see links. ]
Just got back from there, used a 3 PAYG sim which got from Amazon for £8 worked brilliant, connected to AT&T network, unlimited data,300 mins and 5000 txts
Same here I have a three mobile contract sim but I was in Florida for 3 weeks and the data speeds where nothing like three uk but where ok, if you have a 4G phone it will only register at 3G, just be careful because you will get charged for making calls to numbers in the USA, ringing a UK number including a mobile data text will all be covered by you allowance..
The 3 deal is superb for frequent visitors to the US. I have just moved over to them in anticipation of our next trip, and 3 out of the 4 of us in the house are now with 3.
Previously we have bought $30 pay as you go phones out there and used them to phone home no problem, but they don't allow overseas text messages.
Just the fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses. They laughed at Columbus, they laughed at Fulton, they laughed at the Wright brothers. But they also laughed at Bozo the Clown.
