Having issues with sim card cellular network usage

issues & bugs
1

I’ve been using a Tello sim card with r1 for a while now with no issues.

Recently I can only get r1 to connect to the cellular network by doing a full power off and power back on and then r1 will connect but I can only get it to work for like 1 interaction before it disconnects again and stays disconnected until I do a full shutdown again. Soft reboots with ptt x5 don’t have any effect.

I’m using r1 in areas that it worked in before. So idk what the issue is. But at this point the sim card is basically unusable for me since I can only do one interaction per full shutdown. On wifi at home r1 works great but now I can no longer use r1 when I leave the house.

Anyone else having issues with sim card cellular network connectivity?

This seems to have started after the most recent update

Thanks for reporting! We have logged some bugs specifically related to Tello, and we are hard at work fixing them. I am not sure if this will be done in time for the next OTA, but it’s on our radar for sure - appreciate your patience :pray:

Same issue with me. What I’ve been doing, is pull the Sims tray card out and then push back in and then you can do one more interaction.

I’ve done a bit more research and discovered that I’m not alone in this issue. It seems that Tello is not the only company affected, as T-Mobile’s sim cards are also experiencing problems. Therefore, it appears that the issue is with the rabbit.

These connectivity issues and fixes are present exactly as described with my r1 using a GoogleFi simcard. I can get just one interaction before it tries to reconnect itself and fails. A 5-PTT reset can’t jump start the cellular connection but a power cycle or pulling out the sim tray to replace it will.
This was not an issue earlier this year and began happening within the past few updates.

Same here with Tello. No fix in the last few updates. Contacted Support tried all their suggestions but nothing worked.

Yeah, this is happening to me with Tello now too.

It worked for months flawlessly, but then suddenly the other day I can’t connect more than a minute before I get disconnected until device reset, where it just happens again.

I reached out to Tello, but they haven’t been helpful.

Thanks for flagging, folks.

We’re definitely aware of the Tello issues and trying to find a resolution with the network or parent network (since this issue seems to stem from their end, rather than anything we did)

However, I wasn’t aware until the post above that folks were seeing similar with Google Fi.

I’ll escalate this to the team, but I don’t have any news on a fix just yet.

Thanks, Simon. Definitely frustrating having Tello go from working for so long to not without reason, and have them unable to actually help. Guess I’ll start shopping around for other sims since it seems like a consistent issue with them :sweat_smile:

Edit:

After a bit more following up with Tello, it’s working now.

So I had been back and forth with Tello support for 2 days almost 3 - I would give them the info, they would tell me to reset my device, I would say that didn’t work and to double check their end, they would ignore that, rinse and repeat, until the 4th person who got back to me suddenly said it appeared to have been an outage all this time after he checked with their techs. I promptly got a separate new email from their support indicating their techs were working on it, and it’s worked since.

I don’t know why the first 3 people from their support appeared not to have checked it out, and nobody noticed an apparent outage for almost 3 days, or they are just full of sh*t and something else was actually borked, but after hours now without a single drop in service, it seems like it’s working :person_shrugging:

No issues at all with Tello now? That would be good news, but let me try and get other community members to verify.

Yeah I could very well be an edge case, but now it’s the next day and still no issues with Tello after that no service mess, am not using Wifi and haven’t dropped connection anywhere, so I’m hopeful maybe they finally figured something out.

Still having Tello issues over here. Filed a ticket with them and will keep y’all posted.

If they tell you the usual ‘reset your device blah blah’, ask them to look into outages. They told me for days to just reset the device and kept closing my tickets, until finally someone checked with their techs and found out it had been an outage the whole time.

Still have a Tello sim issue for me as of today. Not sure if any progress has been made on troubleshooting/resolving this issue.

I’m having the same issues still as well and Tello has been ZERO help.

So, while Tello did end up working for me for a while, after about 1 1/2 weeks, it went back to not working :frowning:

I’ve reached out to them a few times again now, and they are claiming another ‘outage’, however highly doubtful an outage has lasted yet another week.

@simon I think I remember a ways back there was mention of letting us change APN stuff ourselves, but assuming that never got off the floor? Tello is recommending a different APN now than the default Tmobile one, so might be worth a shot.
