Yarbo was having issues this evening running in an area where with poor HaLow coverage. I noticed Cellular was disabled. When I tried to enable it this error. ![IMG_3599.PNG](https://canada1.discourse-cdn.com/flex007/uploads/yarbo/original/2X/b/b3a9467fb717b4a0f06955cbd31460c4914e4d09.jpeg) I have already rebooted the DC and the Core. No Joy… Any suggestions? Ticket number 111325. @Yarbo-Forum ---

I apologize for the inconvenience caused. As Bryan mentioned, this issue could be related to the 4G data running out, and the 4G usage may not be displayed correctly. If you have followed the instructions from our support team and the issue persists, please let them know through the support ticket, and they will assist you with the next steps. Thank you for your patience and understanding! ---

Upon reading this post I checked the cellular data settings. It was turned off… I could swear that it was turned on after the Yarbo made some maintenance restart couple of days ago. Anyway. I tried to turn it on. “snowflake” appeared but application failed to show me the yellow indicator that now the cellular data is turned on. Tried many times. After this I did the restart for the core and application. Still same thing. I can’t turn on the cellular data. I don’t have this error message as well. Just failing to activate the cellular data. I have my own sim card installed with unlimited data plan. Can’t be that I don’t have any data allowance left. ---

I have seen where if you toggle it on it takes a min to actually go yellow and switch on. Possibly that? Does it have a status of 1 in your diagnostics? 1 is enabled. ---

Cellular data on diagnostic page shows only 0. I know that sometimes it takes long time for the application to show the activation status. It’s not clearly the case this time. I already have reported before that if I did the manual restart for the core it always turned off the cellular data and turned rain detection on. I was very surprised that after the maintenance restart done remotely by Yarbo 3 days ago all the settings remained the same as before the restart they made. I haven’t had any problems since. It’s been mowing non-stop, day and night for about 2 weeks straight. Still doing so. I’m positively surprised that it is really capable doing its work autonomously. Sure I have added many deadens in troublesome areas but if you know Yarbo’s limits and specific needs the mowing areas can be effectively drawn out in the way that 95+% Yarbo will cut and I’m needed only once about in 2 weeks to do the 15 min cleanup with trimmer. For the first year I had the old Husqvarna 450x it also did give me headaches all the time. First summer it did found all the small animal holes and uneven places where it got trapped and was unable to continue on its own. I had to rescue it countless times and at the same time filled yet another hole with dirt not it to get stuck again in the same spot in the future. Second mowing season I almost didn’t had any troubles like this anymore and did enjoyed autonomous mowing experience it did finally provided to me. So in my case I know Yarbo can perform almost as advertised and autonomously but definitely not out from the box for new users. Oh. Just realized this post supposed to be about missing cellular data what I don’t currently really miss… ---

Response from support: > Regarding the error you received, may I kindly ask you to check the following possible reasons: > > 1. The local signal may be too weak in your area. > > 2. Ensure that a foreign SIM card is not being used. > > 3. Confirm that the data card has not expired. > > Once you’ve verified these points, please let us know the results so we can guide you further. 1. My cell phone works without a hitch. 2. Same SIM card that shipped with Yarbo is still in Yarbo. 3. Since its not my SIM card on my account I have no way of knowing if the card has expired. Any ideas? ---

So how would I know if I’m out of data? Can you please have support see if I’m out of data? I did ask in the ticket also. ---

This type of canned response is why people get frustrated. They can see you’re in the US. Why would you be using a different SIM card? How would you know if the Yarbo supplied card is expired? ---

I think the support person should do the following before replying to the ticket: 1. Check to see if I am out of data and when the last data was used. (helpful if last data used was just before some server fix or rollout). 2. Check to see if the SIM card is expired. Then. the first customer interaction should be a ticket saying I am out of data, or my SIM card is expired. If I’m not out of data and the SIM card is not expired, then ask about if I’m using a the original SIM card and about my coverage. If I reply my coverage is good and I’m using the original SIM card, the ticket should be escalated as soon as possible. Then update the ticket to escalated…. I feel this would be a better customer experience. ---

I don’t think the tier 1 person has this level of access. Just a guess. I’m sure there’s a few check boxes to clear before escalation to engineering. I can totally understand your frustration though. Would be nice if the front line could have some more insights into finding and fixing these types of problems. Assuming of course that my assumption is true. ---

I understand that your suggested approach could make communication and troubleshooting more effective. However, our first-level support team does not have the access to check data usage or SIM card status from their side. That’s why your case has already been escalated to our field service engineer, who can look into the root cause in detail. We will work to identify the solution as quickly as possible. ---

I reported this issue also yesterday to Yarbo support. Someone has overnight turned the cellular data on… It now shows in the application that it’s on and also that it’s activated on diagnostics page. ---

Thanks for checking on it @Yarbo-Forum One suggestion would be to write an interface for the first-level support to hit on an internal website that takes say a Yarbo serial number and returns the SIM card status, data used and last contact time. Provide that URL to the first-level support and the user experience is much improved. This is how we handled it when I was in the corporate development world. Given the serial number check the top 5 issues and respond with the information necessary to determine if the issue needs to be escalated. Just a thought… ---

The plot sickens…. > After checking the SIM card management system, we found that no data usage was recorded in August and that the SIM card has remained offline. We also attempted multiple commands provided by the supplier that might resolve the issue, but unfortunately, we were still unable to restore the 4G network. I turned on Record Issue, reproduced the error and turned off Record Issue. Hopefully that will shed some light on the problem. ---

Wonder if the SIM card just needs to be reseated or went bad. If you have another one maybe you could throw it in and try. [Next page](https://forum.yarbo.com/t/cellular-module-is-registering-and-cellular-network-fails-to-activate-no02/3631.md?page=2)
