Travelling to New York tomorrow for 10 days. I already have a T-mobile sim and am just activating it now. It says this on the activation page when choosing between the $2 / $3 a day plan. "Both rate plans give you you unlimited incoming calls, unlimited calls to US mobile and US landline phones, unlimited text messages to US mobile phones and unlimited data; however the $3/day plan will give you faster internet access. The $2/day Pay By The Day plan gives you unlimited data at EDGE speed on T-Mobile's 2G network. The $3/day Pay By The Day plan gives you 200MB data at 3G speed (where available), and after you have used 200MB your internet access will slow down to EDGE speed." Pretty sure my unlocked UK iPhone 5 does not have the correct frequency to use 3G, only EDGE in the USA. Is this correct? So shall I just go with the $2 plan or will the $3 benefit me?
