Android Wear LTE smartwatch on Ting or Project Fi

Disclaimer: These results are informal, based on trying it once casually. Facts on the ground change all the time for LTE service providers in terms of what they allow and charge for it.

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 (1.5 - 3 days battery life without LTE instead of 1 - 1.5 days with LTE).

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

Ting Smartwatch LTE Cost

Ting GSM is recommended as currently the most economical LTE service for phone + data to LTE smartwatches. Ting GSM uses T-Mobile, which is what Project Fi defaults to in non-Fi supported devices. With Ting you do not select a plan. You are billed according to the lowest bucket you fall into for each month. The current Ting cost for an LTE GSM smartwatch is:

$6 (base) + $3 (< 100 minutes phone) + $0 (SMS, assuming you’ll use phone-connected SMS) + $3 (< 100 MB data) = $12/month Ting LTE smartwatch

Ting LTE Smartwatch cost examples:

  • If you don’t make any calls that month (usage is 0 minutes) then subtract $12-$3 = $9 for that month.
  • If you used 400 MB of data that month (maybe watching YouTube on your LTE smartwatch) then you’d fall into the 500 MB bucket – adding $12+$7 = $19 for that month.

If you use the LTE phone and/or data features sparingly, you’ll save $3 - $6 per month with Ting vs. Project Fi. I would bet most people use less than 100 minutes/month of smartwatch phone calls, so $12/month for average Ting LTE smartwatch user may be reasonable.

And the key thing is Ting does not care what you put on Ting, so unlike Project Fi, your phone + data LTE smartwatch usage is totally legit on Ting.

Activate LTE smartwatch on Ting (T-Mobile GSM)

Ting works with Google Voice. I suggest disabling voicemail for LTE smartwatches. Ting voicemail can be easily disabled via the Ting Device Settings under the “Minutes” section, disable “can use voicemail”.

  1. Be sure you request a GSM Ting SIM card. Ting’s SIM card snaps out to fit mini-SIM, micro-SIM, and nano-SIM. Smartwatches are going to need nano-SIM. If you create a Ting account and wait a business day or two, they might email you offering a free SIM. Or you can also order a Ting SIM through Amazon if you’re less patient.
  2. Once you receive the Ting SIM card, have your smartwatch with you and go to the Ting activation page
  3. Get your IMEI number on your Wear device from Settings > Connectivity > Cellular > SIM Status > IMEI. Note that you must have Cellular turned “on” to view the IMEI. Putting the watch on your wrist will help keep it from screen locking before you have the chance to finish typing the IMEI on your laptop web browser. Ting web browser will show that your Wear device is compatible with 2G, 3G and 4G LTE (unless you have the wrong model Wear watch or Ting doesn’t know about your Wear model yet). You can skip this step.
  4. enter your SIM ICCID from the plastic card Ting sent you into the Ting web page. It’s next to the barcode.
  5. I select a new number (don’t use your smartphone number!).
  6. Poweroff your Wear watch, and using the little plastic triangle tool that came with your Wear watch, remove the old nano SIM and put in the Ting SIM. Don’t try to use any other tool or you will mess up your watch. If you don’t have the tool now, just click “other device” and Ting webpage will tell you your new watch phone number.

Ting T-mobile APN

I recommend leaving the default settings alone. APNs for Ting SIM in the LG Watch Sport W280:

  • Tmobile IMS: ims
  • Tmobile GPRS: ← factory default
  • Tmobile MMS: TMUS

Ting smartwatch coverage

Ting coverage maps are intended for standard smartphones. In general LTE smartwatch coverage area is a bit less than smartphones due to the smaller volume to cram everything including antennas into.

Project Fi Smartwatch LTE Cost

  • Note: As of this writing, no phone+data smartwatches are officially allowed by Project Fi. The phone functionality of the Project Fi smartwatch may stop working at any time.
  • The free data-only SIM instead of the phone/voice for smartwatch is an excellent value on Project Fi and is officially allowed, sharing Project Fi data bucket with the main phone.

With Project Fi’s group pricing, the Android Wear smartwatch pools 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.). I believe this is in accord with Project Fi terms of service.
  2. voice/text/data $15/month additional using voice/text/data Project Fi SIM. Note that smartwatch voice use is against Project Fi terms of service. Project Fi/Google Voice will NOT number forward to other Fi devices.

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.

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.).

Activate LTE smartwatch on Project Fi: data-only

  • This use case is in accord with Project Fi terms of service, no tricks needed.
  • You must order a free data-only SIM to get the free shared data
  1. Type the code on the SIM card attachment into a web browser
  2. Power OFF the watch, and using the spanner tool that comes with the LTE watch, remove the AT&T or other SIM
  3. insert the Fi SIM into the LTE watch, then power on
  4. You will have data-only (no phone on watch, texts via phone) LTE Project Fi smartwatch.

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. I notice that the device is on T-mobile normally and may roam to AT&T (not guaranteed to roam, per Project Fi terms of service).

Activate LTE smartwatch on Project Fi: Phone/Text/Data

  • This use is against Project Fi terms of service and may stop working at any time (or not work in the first place)
  • Project Fi/Google Voice will NOT number forward to another Fi device. Maybe a third-party number forwarder would allow one phone number to ring watch and phone.
  • You must use a unique address for your phone and watch.
  • You must order a VOICE/TEXT SIM, not a data SIM for the watch (see next section if you don’t want phone on the watch)
  1. Send a Project Fi group invitation to your second address (perhaps created just for this purpose)
  2. Using a Project Fi compatible smartphone, insert your second voice/text/data SIM.
  3. Activate the Project Fi SIM on your second address
  4. Power OFF the watch, and using the spanner tool that comes with the LTE watch, remove the AT&T or other SIM
  5. insert the Fi SIM into the LTE watch, then power on
  6. You should be immediately able to make/receive phone calls on your T-mobile compatible LTE smartwatch on Project Fi.

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

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.
