Hello! I will be travelling to Brazil in a few months, and I thought about buying some Nobelapp credit for calls and texts to Canada. It says it works with any android or iphone. Has anyone ever tried it? And I was wondering if I still have to unlock my phone for this to work.. I don't think so because the calls are made through an app, but I want to make sure. Here is the link so you know what I am talking about : http://www.nobelcom.com/Canada-phone-cards/from-Brazil-43-55.html
? They have phone cards and credit for the App, I would be using the app credit. Finally, I'd like to know if making calls this way would use my minutes from my normal koodo plan? Thanks a lot!
