Sorry, no it won't @Divit2
You'll need to purchase a US Roaming add-on to get service while in the USA.
Do it just before leaving as they are only good for 15 days once purchased.
When there, connect to the T-Mobile network for data and texts, and when needed for calls, you may need to 'force' your device to 2g (if it has that capability)
@Divit2 No, it will not cover Roaming in the US. It will work when you make a call from Canada to the selected International countries.
I am not a mod. Do not send me private message with your personal info.
