Replace Your Old 3G ELD and Harness with a New Compliant Product
All the major wireless network carriers including AT&T, Verizon, and Sprint have implemented a process known as 3G sunsetting or 3G end-of-life (EOL) to make room for faster 4G and 5G devices. To purchase a new device and replace your old device, follow the steps below based on the type of account you have already established with Transflo: fleet or retail.

Tip: Only Transflo T7 and G7 ELDs are subject to 3G sunsetting. These devices have serial numbers starting with G7. Transflo T9 ELDs (known as T-series ELDs) are already 4G-compliant and do not need to be replaced as part of 3G sunsetting.

- Decide which end-of-life ELD and harness you have now that needs to be replaced. We are offering the following four (4) device replacement options:
OPTION 1: You have a 3G Geotab device and need to replace it with a new Geotab device purchase (majority of customers). An available new 16-pin harness (HRN-GS16K2 $30.00) is also available if needed.
See specs at https://transflomarketplace.com/product/geotab-go9/.
OPTION 2: You have a Volvo 2014 or newer HRN-CM24Y1 and HRN-CE10K2* (see below)
OPTION 3: You have a Mack 2006-2018, HRN-CM24Y1 (+) HRN-CK10K2* (see below)
OPTION 4: You have a Mack 2019+, HRN-CM24Y1 (+) HRN-CE10K2* (see below)
Note: Items marked * include a bundle only option for these customers. See the next step.

For Volvo/Mack customers, follow these additional details below for your ELD and harness:

Volvo 2014+, HRN-CM24Y1 (+) HRN-CE10K2*

Your new device might be branded Transflo or Geotab on its face plate. Either way, your device is a genuine OEM Geotab device.

-
Fleets with 10, 20, or more registered drivers or trucks are being handled by the Sales and Support teams at Transflo. Your account should already have received e-mail from Transflo. If not, contact your Transflo account representative or Support.
We are offering the four (4) device replacement options listed above under ELD Replacement Specifications. When you order, have the following information ready:
-
Current device serial number
-
VIN number (to validate harness type)
-
DOT number
Note: Your current ACH payment setup will remain the same (no changes).
-
-
After receiving your new device, replace each old 3G ELD in the Transflo Telematics portal. Complete the device swap instructions as explained in the following video:
Tip: (Optional) As a fleet customer, your reporting automatically updates for any given unique vehicle before and after the device is swapped out; however, you can add your old device serial number in the comments section and the date if you prefer to simply have this data on record. The device swap is seamless so you will not lose IFTA reporting data or fuel tax information generated by the old number. In other words, it is not necessary to enter the old serial number (device ID) in the comments; it can be useful, but isn’t required.
-
After receiving your new device, complete the 3G Device Termination Request form to submit a request to terminate your old 3G device (you can enter one or more devices on the same form):
Transflo 3G Device Termination Request Form
Important! You must submit a request to terminate your old devices or they will continue to be billed, even after the devices are replaced. Failure to contact us requesting device termination will result in additional non-refundable charges on your account. Once a device is terminated, it is rendered inoperable and cannot be activated for future use. No exceptions.

As a retail customer, you can purchase a new 4G ELD at a physical store location such as Love's, Pilot, or TA, or you can follow the steps below to order online. Either way, as a retail customer who uses only the Transflo HOS app (and not a Mobile Plus app subscription) and who purchased your new ELD online or at a retail location, once you get your replacement device, you must complete all the steps in Update Your Device ID.

Follow these steps only if you are a retail customer and want to purchase your own replacement ELD online:
