Ok i suggest tmobile as they only charge roaming when outside the usa otherwise no problem.Tmobile has a plan which is prepaid called unlimited talk,text, & web which is $50.00 dollars a month and im using the Nokia x2 phone with it which when using data its 2g/gprs and not using 3g or 4g but it goes pretty much at a 3g speed though as i see it.Also if you have a laptop with nokia ovi suite installed you can piggy back off the data from the phone to get on the internet on your laptop.

Also the nokia x2 is flash ready so i go on youtube and watch videos with no problem.I recommend downloading opera though from http://www.mobile9.com/

because it will use less data but then again its a unlimited plan but then why i do it this way because use to have the 1500min talk and text plan that came with only 30mb of data.
