Android Wear smartwatches go better with Project Fi

Cost of Project Fi for Smartwatches

With Project Fi’s group pricing, your Android Wear smartwatch will pool the same data with other devices. There are two ways to use Project Fi on an LTE smartwatch:

  1. data only FREE adding a data-only SIM to your Project Fi plan. You can currently add up to 9 devices this way (tablets, watches, old smartphones, etc.)
  2. voice/text/data $15/month additional using voice/text/data Project Fi SIM.

For #2, your Project Fi cost with smartphone + smartwatch would be:

phone watch subtotal
$20 voice/text $15 voice/text $35
$10 1 GB data $10 1 GB data $20

That’s $55/month total for phone + LTE smartwatch on Project Fi for 2 GB of shared data. You get refunded for data you don’t use, so your total monthly cost would be $45 for 1GB of shared data used and so on.

For me the free data-only SIM is an excellent value, sharing Project Fi data bucket with my main phone.

Users that don’t like to carry their smartphone (e.g. while exercising) and need voice calls may want the extra $15/month voice/data SIM for their LTE smartwatch. Also this voice/data SIM in the LTE smartwatch is a convenient backup phone for those who need to have two phones for reliability (on-call, VIP, etc.).

On an Android Wear watch, you will get LTE emails/phone texts/hangouts/etc AS LONG AS your smartphone is on and internet connected. E.g. you forgot your smartphone at home on the charger–you will get emails etc. on your Android Wear smartwatch over Wifi or LTE.

Project Fi says that devices compatible with T-Mobile will generally work with Project Fi.

Android Wear LTE Project Fi Data Metering

The Project Fi app will break out the usage for each data-only SIM separately, so you can see what the LTE smartwatch vs. tablet vs. phone is using.

Android Wear LTE battery life

When using a data-only Project Fi SIM in your LTE Android Wear smartwatch, you might consider shutting cellular “off” when you don’t use it, since you’ll get an extra 1-2 days of battery life (3-3.5 days battery life without LTE instead of 1.5-2 days with LTE).

If you like to jog or do whatever away from your home every few days, then maybe just leave Cellular on.
