You're misinformed on a couple points re. Project Fi. First, the $20/mo base rate includes zero data. While you're required to sign up for a minimum of 1gb of data, it's essentially just billed at $0.10/MB above and beyond your $20 base rate, since if you use less data than you sign up for, the unused portion is refunded back to you. But to be clear, there's no "included 2GB" in the $20 base rate. Second, your Project Fi sim card will work in pretty much any GSM phone, but it will work just like a T-mobile phone in that case, so far as reception is concerned. So if you put your Fi sim into an iPhone for example, you'll only connect to t-mobile towers, not to any CDMA towers (even though the iPhone may be a cdma-compatible version). Third, project fi also works on the Nexus 6 (the 2-year old Motorola behemoth) and will work on any future Pixel models. As I see it, for someone like you, the only reason NOT to go with Project Fi, is the cost of the data. If you use more than about 6GB/month, there are plans with Sprint, T-Mo, ATT, and VZW that are more economical. At less than 5-6GB of data per month, Project Fi is the way to go. They have a 30-day trial period. You might want to just give it a try and see if you can keep your data usage down. Their integration of wifi is surprisingly good. Most people see their data usage drop significantly without changing their habits.
