Testing TCP/UDP function with EC20 on QNavigator

Using an EC20CEFASG module with a 4G normal SIM card. Downloaded QNavigator, installed OK with SMS and Voice Call fully working. Wanted to proceed with TCP/UDP, PPP and QuecLocator but all of them failed with error message: Fail to activate the context!

From the Setting menu I can see the APN list directory. I did add a new item with my card for local operator “cmhk” that is China Mobile Hong Kong but still could not make PDP ACT to work.

Any idea?

Dear JohnLeung00,
Thanks for your inquiry in Quectel Forums. Please check the following video about how to test TCP function with Qnavigator. Hopefully it is useful to you. If it is still failed in your side, please help to provide your test AT log, then we can check it. Thanks!

The problem came in early when the PDP ACT button was clicked. The Access Point Name is UNINET in the video. Should it be different for each local telecom provider? I am using a CMHK 4g sim card so, I have made modification to APN list under Setting with MCC as 454, MNC as 12, APN is cmhk, URL is http://mms.hk.chinamobile.com/mms. Not sure if it is correct, but the information was copied from my smart phone when the same sim card was installed in it.

Please find a log for your reference.

Thank you for your help.

Dear JohnLeung00,
Yes, the APN should be changed , the UNINET is just an example, you should use the right APN of the SIM card you used. If you cannot confirm it, you can check with local operator. Thanks!
I need the AT log which contains the following error information. Thanks!


If you do not know how to save the AT log, please check the following picture. Thanks!

You may download the log from:

APN of the SIM card was found from first installing it in a common Android smartphone > Settings > SIM cards & mobile networks > SIM CARD SETTINGS > Access Point Names > CMHK.

SIM Card bought from a local convenience store does not provide technical support, unfortunately.

Dear JohnLeung00,
I think you choose the wrong module type, please choose the LTE module not GSM module. Thanks!
Please close Qnavigator, then open it again, pay attention to that select module type, must choose LTE module. Thanks!

I am using V1.4, and there are only options for me as shown. GSM/GPRS is the only option that works.
Is it the problem of QNavigator version?

Dear JohnLeung00,
Please click the following link to download the latest Qnavigator to have a try again. Thanks!

With Qnavigator v1.6.10 everything is OK now. Thank you very much for your help.

I am glad to hear that. You can go on your test. If you need any technical support, please do not hesitate to contact Quectel. Thanks!
