I am using EG25-G with the EVK, here I am trying to use Jio SIM to create PPP connection, send SMS and Call a number, so here while I am using Jio SIM (Indian Service Provider), I am facing problem with Sending SMS or Making a call, but when I use Idea SIM, it works completely fine.
Here when I send the SMS using QNavigator tool, the tool goes non-responsive for some time and then gives an error of SMS sending failed, after that the Module is not responsive for any command, until later it gives +CMS ERROR: unknown error.and than the cycle continues, for every action of Sending SMS, or Calling or trying to make a PPP connection the Module goes non-responsive.
Dear Sir,
Thanks for your inquiry in Quectel forum.
About your issue, it is better to provide your test AT log. And please double check whether the Jio SIM card can support SMS and Call function. You can check the AT+CREG? and AT+CEREG? to confirm whether the module can register on network successful with Jio SIM card. Thanks!
Dear Sir,
Thanks for your updating.
Could you share the whole test log which contains the SMS and Call function? The log you provide can prove that the module already register on network successful. You can use Qnavigator tool to test it. Thanks!
Dear Sir,
Please double check that whether the SIM card is ok now, the following command means that the network already reject the module to register on network. So please double check it. Thanks!
I have already checked that, it gives that error once the system fails to send SMS. But after the restart, the SIM works fine (only registration part).
For Call its directly going into that mode.
Also after registering the SIM, if I try to call that number, it says the cell is switched off.
Dear Sir,
Just as i have said that if you can confirm your SIM card is OK, you can contact our local FAE to catch module debug to analyze the reason, you can email to support@quectel.com. But i am still suspect that the SIM card cannot support Call or SMS. Thanks!
I can understand the point you are raising, but as I said earlier, I have already tested the SIM for SMS, Calls and Internet using Cell Phone and its working completely fine.
I have already initiated the support from local team, but as it was getting delayed may be because of this Covid situation, i though if we could get it sorted here, things could move faster.
If that it is better to catch debug log to analyze it. You can ask the local representative to send your log tool and ask them to help to analyze it after you catch the log. Thanks!
