How to dial-up Internet access for Quectel RM502Q-AE

Hi, yes i waited all the afternoon, but didn’t get the location.
What else can i do?
Thanks

I am afaid I cannot give you any advice.
Unless I am there, I don’t know why it is.

Hi, thanks a lot for all your answers and your help.

After changing the place where we did the tests, it finally worked.

Good to hear that !
If it still doesn’t work, just send it over and let Quectel check it.

Hi Mr.Wang

I have encountered the same situation as stated and I have refered to the pdf that you had given. I have used SSCOM(used under windows) to run AT commands as given by Waveshare website. RM500Q-GL 5G HAT - Waveshare Wiki
However, when i give commands associated with AT+QCRMTOOL , SSCOM said error.
May i know how to configure the RM502Q-AE module to give a cellular network?

Thank you!

@Qinfan

Could you show the AT results?

AT+COPS?
AT+QENG=“servingcell”

Do you use the AT+QCRMTOOL to set up data call for RM502Q-AE?

ATCOMMANDS
Hi Mr. Wang
Here it is.
I didn’t use AT+QCRMTOOL as it will appears error in SSOCOM. I have use the 3 commands “AT+QENG=“servingcell”, AT+QCFG=“usbnet”,2 , AT+CFUN=1,1” to dail up the internet.
I actually can see the cellular internet whenever I connect the module to my laptop using USB(As the image shown below) , it’s just that it will disappear after serveral seconds and then appear again(seens like not very stable).

Thanks for replying!

If you already have set it mbim mode,

please update the driver to Mobile Broadband Interface Model.

Open the device manager, right click the Quectel wireless ethernet Adapter, choose the “Update Driver”.

The device disapper again and again is because that it match the wrong driver.

Hi Mr.Wang

Thanks for your lately reply!

However, it said the driver is already updated to the lastest version when i trying to update Quectel Wireless Ethernet Adapter #3.
And when i conducted a network diagonosis to the cellular network, here is the result. It seems like the network adapter for cellullar network 3 is not running, they can not assign the ip to the adapter.

Thanks!

Manually Switch the driver to
Mobile Broadband Interface Model

Hi Mr.Wang

Thank you for your patient reply!
It solved the problem! But it seems like i can’t connect it to access the internet. May i know how to make it to provide a network?

Thank you!

Do you know what the APN is?
Please set the APN by
AT+CGDCONT=1,“IPV4V6”,“apn”

Hi!

I have already set it but when i trying to activate it, it appears error.
apn

That means you cannot active it with that APN.

Please check:
Whether it is a valid apn?
Maybe it was rejected by the operater/internet provider.

Have you tried another sim card?

apnsetting
Hi!

I have tried with another card and here is the result!

test the sim card with APN “andbox.singtel.com” on Windows.

Hi Mr.Wang

I have tried but it said can’t find the apn.
I am quite sure that the sim card have data plans and I have already set the apn using AT+CGDCONT and activate it also.

I think it’s beacuse the apn setting is failed.
When i enter AT+CGACT=1,1, it shows CME error: 100

Querry with;

AT+CGACT?

If you cannot see the:

+CGACT: 1,1

it means that with the APN the RM50Q could not set up data call.
