If you are travelling to the USA you may be thinking about a mobile phone. Whether to take your own and hope there are no surprise bills when you get home or buy one when you get here.
I don't have a mobile phone in Australia but if I did I would bring it, not use as a phone but because it would have all my contact information in it. I decided to buy one in USA as I would need it to contact my daughter and other people I would be likely to meet.
They have a wide range of "No Contract" Phones from most phone companies and from cheap to expensive however for my purposes I only needed a cheaper model.
I finally decided on TRACPHONE and picked the LG440S, normally $19.95 but on special at $9.95 which also included a deal that doubled whatever minutes I buy for the life of the phone.
The shop staff did all the work of setting up the phone for me, I purchased 60 minutes for $20.00 and 10 minutes later I had a phone with 120 minutes and good for 120 days.
I like the phone it is very user friendly, however it is perhaps a little retro for some people.
I should add that I am not a big phone user
