Quectel modem for Telecom operator outside of US - APN selection

Re: Quectel 5G modem update/firmware for RB5 platform

Hello,

I'm in Germany working with the RB5. We have 7 of them in the lab.
Following the instructions for connecting the drone via modem (https://docs.modalai.com/voxl-modem/),

how to select the APN if none of the option is working
how to connect the drone via modem to a 5G router that has a SIM card?

----------------------------https://docs.modalai.com/voxl-modem/---------------
Which APN is correct for your SIM card?

AT&T - IoT device - APN: m2m.com.attz
AT&T - Laptop or Tablet - APN: broadband
AT&T - Smartphone - APN: phone
T-Mobile - APN: fast.t-mobile.com
Verizon - APN: vzwinternet
Google Fi - APN: h2g2

m2m.com.attz 4) fast.t-mobile.com 7) Custom
broadband 5) vzwinternet
phone 6) googlefi
#?

Best wishes,

Eric Katzfey

@tahawaru Probably would want to choose custom then. What operator are you using? What APN do they specify?

@Eric-Katzfey

I have a SIM card from Deutsche Telekom(https://www.telekom.de/hilfe/mobilfunk/mobiles-internet/mobilfunkstandards/apn-ratgeber?samChecked=true). From the above link and on my phone,one can read:
APN: internet.v6.telekom

I don't know if I will need a username and password after entering these data.
Probably, I should ask them as well.

Best wishes,

I have tried with a telekom SIM card (APN: internet.v6.telekom). I have the following output:

@tahawaru Before using quectel-CM can you try running the following to set the network mode to LTE + 5G as a test:

echo -ne "AT+QNWPREFCFG=\"mode_pref\",LTE:NR5G\r" | busybox microcom -t 1000 /dev/ttyUSB2

And as a note this is how you can experiment with sending AT commands to the modem for debugging purposes

tahawaru

@tom
Done!
rb5:~$ echo -ne "AT+QNWPREFCFG="mode_pref",LTE:NR5G\r" | busybox microcom -t 1000 /dev/ttyUSB2
AT+QNWPREFCFG="mode_pref",LTE:NR5G
OK

What is the correct procedure to have the 5G connection up and running?

tom

@tahawaru You might have to reach out to your telecom company to confirm that they allow connection to their network via. this Quectel modem

tahawaru

@tom

I have reached out to the SIM card and APN telecoms provider.
They gave me a username and a password.
Where can I input those 2 parameters?

Best wishes,

tom

@tahawaru quectel-CM is not something that we developed, it's a tool from Quectel themselves so I can't give you a definitive answer but looking at quectel-CM -h it looks like you can do something like this:

quectel-CM -s $APN $USERNAME $PASSWORD

This is the source if you want to see how that flag's arg parsing works: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-modem/-/blob/master/src/quectel-CM/main.c?ref_type=heads#L665

@tom

I'm using a mobile prepaid SIM card.
There are other SIMs available such as IoT SIMs.
May be an IoT SIM card will be suitable for this situation.

tom

@tahawaru I like using Google Fi, super easy to setup
