This phone has become the most frustrating one I ever owned. I have been unable to access the data network from the very beginning. Mobile data is selected. Automatically select network is selected. Clicking on Access Point Names brings up a page that says “Access Point Name settings are not available for this user”. If I click on SIM status it shows Mobile network state as “Disconnected” w/ no way to connect. Mobile data network type is listed as “NR SA”. I’ve tried all the tricks I know and I’m at my wits end with this thing. I have a trouble ticket open with Tello, but they are asking for APN settings I can’t access.

I would like to add that I also tried switching Airplane mode on and off, as that was a suggestion. I also reset the mobile network settings & reset the bluetooth & Wi-Fi settings as part of the troubleshooting with the Tello tech support. Nothing is making this thing access the mobile data network.

I got a Tello eSIM today and I had the same issue: voice calls were fine but could not get mobile data. (FYI, I am running Iode OS version 6.6 instead of version 6.3 that the Brax3 shipped with, but I doubt that has anything to do with the issue or its resolution.) I was able to resolve the issue by following these two steps (your mileage may vary):
- I performed a factory reset (search for factory reset in settings). At least in my case, this operation preserved the Tello eSIM configuration
- I set the APN during Iode setup phase with these settings that user wardee posted in another thread (Don’t set your wifi during this phase. You can do that later. Under mobile data you can find the APN menu. Click on the “+” button to add your APN) :
- Name: Tello
- APN: wholesale
- Proxy: (leave blank)
- Port: 8080
- Username & Password: (leave blank)
- Server: (leave blank)
- MMSC: http://wholesale.mmsmvno.com/mms/wapenc
- MMS Proxy: (leave blank)
- MMS Port: (leave blank)
- MCC: 310 (I did not have this field, so I skipped it)
- MNC: 240 (I did not have this field, so I skipped it)
- Authentication Type: (leave blank)
- APN Type: default,supl,mms (make sure all others are unchecked)
- APN Protocol: IPv4/IPv6
- APN Roaming Protocol: IPv4/IPv6
- Bearer or Network Type: LTE or Unspecified (I left it as Unspecified )

This actually worked. I have been testing it for a few hours & it is using the mobile data network now. The question I have now is, how on Earth did you & the Wardee fellow figure this out & what would everyone be doing now if you hadn’t? This is my first time trying a Brax phone & it seems to be they are lacking in the support department. Tello had given up & told me if the last ditch suggestions they had didn’t work, to try another phone.

I am not sure where @wardee got that information, but I am glad she found it and posted it. I don’t believe this issue was caused by the Brax3 phone per se. Default APN settings usually work with the mainstream carriers (AT&T, Verizon, and T-Mobile in the United States). MVNOs like Tello operate on one of those host networks but have their own unique network identifiers and configurations that differ from the host. The problem is that both the Brax3 phone and the Iode OS are niche products that most support people at these MVNOs (or even the host operators) will be unfamiliar with. That is probably why they were not able to help you. I found the solution after a lot of trial and error, and the factory reset was my desperate last resort.
The Brax3 is an open-source product with only a few thousand devices ever made or sold. They certainly don’t make enough of a profit to be able to hire dedicated support personnel. I am thankful for this community and forum where people volunteer to help each other. I agree that the support is not quite as seamless as you’d get from a large corporation. If you want an affordable phone that gives you the most control over your own device, then the Brax3 is one of the very few options on the market. That trade-off is worth it to me, but not everyone might agree.
In any case, I am glad the solution worked for you. Good to know it wasn’t just me!

@handsolo and @inverdell I just asked Grok and went back and forth until it worked.
