Mom,

Just be careful on the Passport plan. In the US you'd pay around $10 per GB for data. On that plan you will pay $150/GB for the $120 plan, $200/GB on the $60 plan and $250/GB on the $30 plan. Be sure to turn off data when you're not using it as it will continue to use data. Any apps that run can use data too. Also stay away from any video - it's amazing how much data is used just to watch one short youtube video. Stream Netflix and you're in for a nasty surprise!
