    I am using a Nexus 6 on Fi as a 2nd line to test it out. I kept my main number on T-Mobile. I've used my Nexus 6 extensively on T-Mobile before switching to Fi and activating the sim card last week. So far I'm extremely unimpressed. I thought that Fi would be using T-Mobile and Sprint towers? Why are my speeds on Fi so abyssmal compared to my speeds on T-Mobile with the exact same phone? And why isn't my 6 on Fi now even getting the same type of signal (3g vs 4g vs LTE)? I changed no settings when switching to Fi, I simply downloaded the Fi app and activated my Fi sim card and imported my google voice #.

    Here are my test results using the exact same Nexus 6 on T-Mobile and then Fi:

    T-Mobile:
    Home:
    4-5 bars LTE
    60 mb/s down
    25 mb/s up

    Work:
    3-4 bars LTE
    35 mb/s down
    20 mb/s up

    Fi:
    Home: 2-3 bars 3G
    1.1 mb/s down
    .4 mb/s up

    Work: 1-2 bars 3G
    .8 mb/s down
    .2 mb/s up

    What's wrong here??

    Sounds like it is not connecting correctly. I advise doing a full factory reset on the phone, and starting fresh.

    You should be connecting to the same T-Mobile lte network that you were before.

    Picked up this method on the Google+ Project Fi. Worked for me to get the data speeds normal

    1. Power down phone and remove your sim.
    2. Start phone with no sim installed.
    3. Clear cache and data for Project Fi app.
    4. Uninstall Project Fi app.
    5. Under Settings-> Storage, clear your cached data (scroll to the bottom for this)
    6. Power down phone
    7 Put sim back in and restart.

    How do I do number 3? I know how to clear cache in settings --> storage but how do I clear cache and data for the project fi app?

    I'm trying to avoid doing a full reset if possible.

    To clear the cache for the app, you go to settings, apps, select project fi and there will be a clear cache button.

    This worked! Connected to LTE now at my normal speeds.

    Mine worked fine. But I bought the Nexus through Fi, so everything was clean from the get go. Still on 5.1 but not a deal breaker.

    At what point do you reinstall the Project Fi app? After SIM is in and rebooted?

    Thanks
