Supported devices

  • PodiumConnect
  • RaceCapture/Apex
  • RaceCapture/Pro MK3, MK2

Get a SIM card

The RaceCapture telemetry unit requires a full-sized SIM card with a compatible data plan from a supported GSM carrier.

Which SIM card to get?

This is largely determined by the coverage map of the race track you'll be at. Use the coverage map checker for the respective carriers.

USA

Verizon (4G RaceCapture / PodiumConnect systems only)

If you have the newer 4G enabled system, you can also use a Verizon SIM card (USA). If your unit was bundled with a SIM card, you can call Wireless Zone at 508-834-3311 for activation and access to special data plan options.

If you did not receive a bundled SIM card, visit a Verizon store and ask for a pre-paid data only SIM for a hotspot or tablet (data only). If you already have a Verizon account, you can also add a SIM to your plan that shares your plan's data.

  • Note - If you have a 3G system, Verizon is not available for telemetry. Your best options are AT&T, T-Mobile or FreedomPop. Check your order details if you are not certain which unit you have.
Freedom Pop

We currently recommend the $0/month plan from FreedomPop. Based on the AT&T network, it offers good performance in rural areas across the USA.

FreedomPop's $0 SIM card plan includes 200MB of data/month - this should cover more than enough for a 24H endurance race.

To set up RaceCapture, just select FreedomPop from the list of cellular providers in the RaceCapture App. If you don't see it, set a custom APN and specify fp.com.attz as the APN host, with no user name or password.

Sign up for a FreedomPop plan today

  • Note: When signing up, FreedomPop will place you in a default monthly plan. If you want their basic $0/month plan, you will need to downgrade using your account - click through the warning messages until you're at the Basic/Free plan. When you are done, your billing page should show $0/month.

See the step by step guide for setting up FreedomPop

AT&T

AT&T is a good option as they have announced affordable plans targeting tablets and other data-only devices.

AT&T Gophone plans

When you arrive at the store:

  • Critically important: Ask for a pre-paid SIM card for a tablet data plan. It must be a tablet data plan; problems have been reported with phone SIMs.
    • Request a full-sized SIM (RaceCapture/Pro) or a micro SIM (RaceCapture/Apex)
  • IMEI: usually they will use a default IMEI. If they require one, you can from the system status page

AT&T Coverage Map tool

  • Important note about AT&T and legacy 2.5G modules in RaceCapture/Pro MK2

As of the end of 2016, AT&T ended their support for 2G devices. You have two options to enable live-streaming cellular data:

  • Use a carrier that still supports 2G Data, such as T-Mobile
  • Upgrade your RaceCapture/Pro MK2 with the 3.5G module
T-Mobile

Purchase a "Pay By the Day" SIM card from your local T-Mobile dealer. We recommend picking a plan with the 2G/3G unlimited data, that will work with a tablet, which is currently $3 USD/day. The plan is only charged when data is actually used during a 24 hour period.

This is the only US carrier that supports 2G - it should work with the 2G cellular module.

When you arrive at the store:

  • Ask for a pre-paid $3/day plan
    • Request a full-sized SIM (RaceCapture/Pro) or a micro SIM (RaceCapture/Apex)
  • IMEI: usually they will use a default IMEI. If they require one, you can get the IMEI from the system status page

Global

RaceCapture/Pro MK3, RaceCapture/Apex and PodiumConnect use a world-wide compatible GSM cellular module. Check with your carrier for support. You will also likely need to set a custom APN setting in the telemetry configuration; the carrier will have these APN settings available.

You will need:

  • APN Host
  • APN User name (might be blank)
  • APN Password (might be blank)

Enter these values into the cellular provider section under Setup / Wireless:

RaceCapture telemetry custom apn settings.png

How much data will I need?

There are a number of factors that affect data usage:

  • Duration of telemetry session
  • Number of channels enabled
  • Sample Rate of channels

For about 30 channels transmitting at 5-10Hz we have seen about 150MB of usage across a 2 day endurance racing weekend (15-20 hours of transmit time).

What if the store is asking for the IMEI?

Usually the store will set a default IMEI number, especially if you tell them the SIM may be swapped between devices. If they require setting a real number, you can get the IMEI by connecting to RaceCapture/Pro and checking the cellular section of the app's System Status page:

Installing the SIM card

RaceCapture/Apex

  • Remove the cover from the rear of the enclosure, and insert the SIM card into the bottom slot of the silver card holder (below the top SD card position).

RaceCapture/Pro MK3

  • Use a pen, stylus or similar press the eject button next to the SIM card slot on the front panel - the card slot will pop out slightly. Manually withdraw it.

MK3 telemetry slot.jpg

  • Insert the SIM card into the holder, noting the angled notch. Re-insert with the SIM card facing up and press until the front edge is flush with the face, until you feel the tray seat.
  • Important: The card carrier should slide in smoothly, and require just a bit of force to lock in to place. Take care to not force the card in at an angle.

RaceCapture/Pro MK2

  • Use a pen, stylus or similar press the eject button next to the SIM card slot - the card slot will pop out slightly. Manually withdraw it.

RaceCapturePro MK2 SIM card eject.jpg

  • Insert the SIM card into the holder, noting the angled notch. Re-insert with the SIM card facing down and press until the front edge is flush or just below the surface of the enclosure face, and you feel the tray seat.
  • Important: The card carrier should slide in smoothly, and require just a bit of force to lock in to place. Take care to not force the card in at an angle.

SIM adapters

Note that full-sized SIM cards can be cut down to micro-sized, and correspondingly micro SIMs can be inserted into a full-sized SIM card adapter.

Attach cellular antenna

Connect the included antenna to the antenna port of your RaceCapture device. Tighten to 4-6 inch/lbs - just beyond finger-tight if you don't have the appropriate torque wrench.

  • Important: Do not over-tighten antenna connection

Antenna placement

If you are using a roof-mount antenna, place the cellular antenna as far away from the GPS antenna as practically possible. About 1 meter (3 foot) separation is optimal. Racecapture telemetry gps antenna placement.jpg
