I need a detailed explanation on how to register and use a USIM card for the Yarbo robot. Do I just need to register it with the carrier and insert it, or are there additional program settings required?

The SIM card provided with Yarbo is already installed and activated. We use a Global IoT SIM card, so there is no need to register it with a local carrier or configure any additional settings. No repeater is required. As long as there is cellular coverage in your area, Yarbo should connect automatically.

This may help a little. It needs to be a physical SIM, data plan only, and activated already. Where to Find the SIM Card Slot The SIM card is installed inside the rover, located within the battery storage compartment.

Thank you for your answer. Looking at the Yarbo Wiki you linked, it says 2GB of data is provided for free per month. Does the device automatically connect to the internet just by inserting the provided SIM card, regardless of the country’s communication service network or repeaters? Also, I am curious about how it actually sends and receives data. I’m still a beginner testing out my Yarbo. I am currently in South Korea, and since I am not fluent in English, I have to use a translator for the manual, which makes things a bit difficult.

I thought the 2GB per month was only for the first two years? Has that changed?

Correct, 2GB/month free for the first two years. AFAIK, this has not changed as of yet.

Thank you for your previous assistance. I have a few more questions regarding the SIM card and data management for my Yarbo unit. Real-time monitoring: Is there a way to verify in real-time that the SIM card is active and actively transmitting data? Data usage management: How can I monitor and manage my data usage to ensure it stays within limits? Are there any built-in tools or settings for this? I would appreciate any guidance you could provide on this matter.

Best way is to toggle cellular on. Check in the diagnostics for a status of 1. Then turn off your Data Center and disable bluetooth on your phone. Make sure the core is not connected to your home wifi. Then see if you can still connect to your core. Unfortunately, there are no tools to keep it under any caps. The included plan will automatically stop working when it hits the cap. But, if HaLow is working properly on your DC, you should almost never need to use cellular. It will only use it if HaLow and then WiFi become too poor in signal strength.

I have a follow-up question regarding data usage. If the cellular function is activated, but the device is also connected to Wi-Fi or HaLow, should I understand that the device will prioritize Wi-Fi/HaLow and therefore not consume cellular data? I would like to confirm if there is a specific priority logic for network connections to avoid unnecessary data costs. Thank you for your help.

That is correct. Priority is HaLow, WiFi, Cellular in that order or precedence.

May I ask a question about a different matter? English is not my first language, so I would like to ask for some clarification regarding the terminology used in the Yarbo app’s mapping settings. I understand the literal dictionary meanings of “Pathway” and “Deadend,” but I am unsure how these terms are functionally applied within the Yarbo system. Could you please explain the differences between them and how each feature affects the mapping or work process during the zone setup? Any explanation would be very helpful. Thank you.
