So far, the only fix I can come up with is to do the following::

1. turn off network data

2. remove sim card

3. insert sim card

4. turn on cellular data

5. select ATT network

it connects every time. 

I'm also having the same issue with my chromebook and I've been trying to get a resolution for a month now. I have went through 3 sim cards and finally just took it up to my local AT&T store and they gave me a Warranty Claims number to call to get a new laptop and I can't get a real person on the phone. The number they gave me to call to get my laptop replaced is 1-800-801-1101. I hope you have better luck than I did.

I am having the same issue. I just bought my laptop one day ago and it’s useless to me. I need to connect when I don’t have my cell or wifi to connect to. Has anyone found a solution?

I called the warranty claim number for AT&T again and finally got to speak to a real person. They contacted Samsung directly and patched me through to them. Samsung sent me a label to ship them my Chromebook so they can fix the problem. I'm hoping this will be the solution needed.

Did sending it off resolve the problem? I am having the same issue and have done what everyone else has and my only option is to send it to Samsung.

I am having the same problem. I keep getting two error messages when I try to connect via my ATT Sims card for my Samsung Galaxy Chromebook Go purchased around June 1, 2022.

I am on my 3rd SIM card to try and get this to work. I have been back to the ATT store multiple times, no luck. I called ATT tech support, no luck. After a few hours on the phone and remote work they were just as baffled. This is beyond frustrating. I live in a rural area and this is the only way I can get internet access. I can't use up all my hotspot data on my cell phone to use my Chromebook for my work.

I get this error message:

Network Connection Error

Failed to connect to network 'ATT':modem not registered

Or 

Another error code that I forgot to write out.

I am in the crosh right now running code status checks to see what I can to see if I can figure out how to fix this. No luck yet.

Does anyone know how to register the modem?
