iPhone 6 takes a nano sim and the Q10 takes micro.
Get that and then its as simple as swapping the SIM.
This. It actually works. I would never have even thought of trying to run Project Fi on my ancient 3G AT&T iPad 2 if I had not read the post from monkeytrain42. These are the steps to get it up and running:
The Project Fi sim will be a nano, and the iPad 2 uses the older micro form factor, so while you are waiting for your sim to arrive from Google you need to purchase a nano to micro adapter. Amazon has a bunch of different sellers for them, but be sure to check the expected delivery dates, because I saw that some would not have arrived for weeks. I bought mine from http://www.amazon.com/gp/product/B00HSOUQXM? and the adapter arrived before the sim itself.
Install the sim into the adapter and eject the old one. There is a short video at https://www.youtube.com/watch?v=q-kSp267vK8 which sounds like it is being narrated by a six year old, but the steps are correct. Make sure you pay attention to the alignment of both the sim holder and the sim itself so that you can reinstall everything correctly.
Once I had the new sim in and put in my WiFi password, WiFi worked immediately, but the cellular data did not. I could check this by turning off WiFi in Settings > General and trying to load a web page. I reset the network connection to clear out any old AT&T information: Settings > General > Reset (at the bottom of the page) > Reset Network Settings
When the iPad came back up I was still not getting cellular data. The problem turned out to be that the iPad 2 is so old it cannot automatically populate the information the new sim needs. After a bit of looking around I found the answer. Go to Settings > Cellular Data > APN Settings. In the APN box put in h2g2 Leave the Username and Password boxes blank.
With that, both 3G and WiFi worked like a charm. I had replaced that old iPad 2 with a Samsung WiFi-only tablet over a year ago, and had to go digging around in a closet just to find the old thing. It is large and heavy and thick, but it works great, and now when I am out and need to get connectivity where there is no WiFI, the old iPad is once again my go-to gadget.
Thank you for the suggestion monkeytrain42
