I could be wrong, but I seem to recall that the Clarity's HondaLink service relies on the 3G network, but that is to be shutdown forever on Feb 22 this year. Owners of other Honda vehicle models have the option to download an on-line software update, as long as they do so before Feb 22 (see Public Knowledge: HondaLink®: Over the Air - Software Update for Wireless Network Upgrade (force.com). The Clarity is not mentioned in that list, though.
Is my memory of Clarity's HondaLink requiring 3G wrong, or has anyone have more insight into this situation?

We used to think we had 3G but then someone found pretty conclusive evidence that we have 4G. Other evidence is that the Clarity is not on the list of Honda models that are affected by the end of 3G.

Thanks for the info that Clarity uses 4G. I suspected that might be the case, but it is better to know for sure.

The reason that we know (or at least assume) that Clarity uses that chipset is because someone found the part number for the telematics unit for the Clarity, then they found a photo of that part which listed an FCC ID, and when they looked up the FCC ID it included LE920-NA (and a few others likely for other countries). As you have posted the LE920-NA manual states that it supports LTE.

Or Honda could have simply put out a statement something like, "Clarity uses 4G and will not be affected". But at least we have pretty good evidence that we will be fine.

What does Clarity directly use the cell network for? I thought it used your cell phone linked via Bluetooth or wifi.
The post that you are replying to was a first time post by a new member who I think was probably trying to add a comment to one of the other threads about maintenance minder, but they accidentally posted their comment to this thread.

As for your question, Clarity uses the cellular network to communicate charge status, climate status and location to the Honda server. The Honda server then sends this information via standard Internet to the HondaLink app in our phones. Also the commands that we send to the car for charging and climate are sent first to Honda via Internet, the Honda server then sends the commands to the car via the cellular network.

Optionally you can connect your Clarity to your home WiFi network, in which case Honda will communicate with the car via Internet instead of cellular. Of course this only works when your car is parked at home, otherwise it uses the cellular network.

Bluetooth is used for direct connection between the phone and the car, but only for lesser used functions such as odometer reading and sending a destination from the HondaLink app to the NAV system. These functions are lesser used because they are clunky and poorly designed. So realistically the Bluetooth connection is not really needed.

Honda knows exactly how many miles every car has been driven using ice. Therefore knowing a car does not need oil change but recommends it is fraudulent.
I would not say it is fraudulent if it is the manufacturer itself that determines the criteria for an oil change and merely makes that recommendation based upon that criteria. If I’m a hair stylist and you come to me to get your haircut, I may recommend that you come back in four weeks. Whether you decide to follow my recommendation is entirely up to you. The number of miles driven on ICE maybe be part of the criteria that is used to determine oil change interval but I’m sure that the elapsed time since last oil change is also part of the criteria.

I noticed that the Clarity lumps asking for an oil change when it also asks for a tire rotation. Do the tire rotation and reset only the tire rotation. You'll have about 4k mi more before it again asks for an oil change...

HondaLink sucks compared to the My Ford Mobile we came from, '18 Clarity vs '13 C-MAX Energi. BUT the Ford owners are suffering trying to upgrade from 3G to 4G, with mixed reviews on the process...
