Puli - How to change (cellular) network provider?

alzhao · 2022-09-11T10:46:36.020Z

I have never done that. I can send you a manual of AT command to explore.

Have you already figured out how to do it, I have the same problem?!

spamatiki · 2023-12-20T10:15:49.104Z

Never figured it out.
It just „does not work“
Really annoying

XXXLA · 2023-12-20T14:57:23.217Z

Do you want to tell me how to do it?

admon · 2023-12-20T15:37:32.387Z

I’ll try to play around with the AT commands, but there is something I don’t understand:

After my SIM connected I am trying to get my current network:
AT+COPS?
which results in
+COPS: 0,0,"Telekom.de heyah",7

That’s great.

But when I do
AT+COPS=?
to list all available networks, the modem dies. GUI tells me the USB modem is unavailable and the “Internet” LED on the front turns off. Ping is working without problem - so something is odd here.

After a reboot everything is fine again. The same happens when I send AT-COPS=? by using socat /dev/ttyUSB2

@lizh can you have a look?

lizh · 2023-12-21T14:13:25.577Z

What model of device?

If the AT instruction is not supported, the AT instruction interface is blocked.
You won’t be able to get information through the AT command.The interface displayed on the web interface also disappears.

lizh:

What model of device?

XE3000

lizh:

If the AT instruction is not supported, the AT instruction interface is blocked.

How to revive it again?

lizh · 2023-12-21T14:40:48.830Z

XE3000 should use /dev/mhi_DUN.

Please help exec :

AT+QCFG=“data_interface”

admon · 2023-12-22T19:21:23.119Z

Not sure if I’m smarter than before now:

AT+QCFG="data_interface"
+QCFG: "data_interface",1,0

OK

and the modem is gone again.

Edit: But just for a few seconds, than it comes back. Is this the command to revive it?

lizh · 2023-12-25T08:34:07.294Z

No, This is to check the modem communication mode.

I need a remote debug.Could you share with cloud platform:‘gl.inet_support’.

admon · 2023-12-26T12:37:06.798Z

Device shared. Maybe you will even find the issue why the cellular GUI is gone…

lizh · 2023-12-27T07:15:53.353Z

I need the known the Mac of the device,otherwise, I don’t know what device it is.Please send to me via Message.

admon · 2023-12-27T07:55:21.524Z

Sorry, sent it to you.

lizh · 2023-12-27T11:45:36.028Z

Hi admon:

‘AT+COPS=?’ is a long response instruction.But web pages do not support long response instructions.

It will block the AT instruction channel so that it cannot detect the modem.

It needs to be executed with the following instructions:
gl_modem -B 0001:01:00.0 SAT sp AT+COPS=?

Yey, that is something I can work with!

I'm getting the same 3 providers listet in my location: Vodafone, Telekom and O2. But the main question still remains: how can I switch from currently Vodafone to let's say Telekom? This is something really essential if we talk about travel router. In my iphone I have the setting: automatic provider selection. If this is selected, the iphone picks the best possible connection that fits to my vodafone simcard. But if Vodafone connectivity sucks in my location, I can unselect "automatic provider selection" and I get a list as shown above where I can select the one that has highest signal quality. Again..... this is essential when travelling.
Initially I thought this was done by selecting profiles...... but this is not working and has no functionality in my X3000

admon · 2024-06-07T17:06:10.806Z

You can't.

You can only connect to providers your SIM is valid for. So choosing a different provider is mostly only possible while being abroad due to roaming.

And then you need to use AT commands, unfortunately. A GUI isn't available.

brewie · 2024-06-07T17:15:03.553Z

thx admon for your fast response! I tried last week in France. I was travelling and on my iphone I had to switch from vodafone (my provider in Germany) to Orange in France. So I allowed roaming on the iphone and switched off the automatic provider selection and selected Orange instead. Switching the provider in France in the X3000 with a vodafone card was not easy at all. I couldn't make it happen.
Can you give me some instructions? I can connect with SSH and I can use manual AT commands. Maybe there is a way to save AT commands in future so that these can be reused easily to switch provider

admon · 2024-06-07T17:18:20.991Z

Unfortunately, I can't help with that because I don't use cellular internet.
But a collection of AT commands is available here: [Summary] AT commands
