esim

[damianogiacomi]

Can you explain me what I need to do in order to have the esim ? Do I need a physical component ? I am new to this subject if someone can help me a little bit. Thanks

Hi Damian,

Typically you need to register your eSIM to connect to the cellular network in general. (This you must check out with Telit)

If it's already registered and you have soldered on the eSIM as well as following the instructions in my last post you should be able to connect to nrf cloud.

I now assume you are doing this on the nrf91 DK ? please correct me if this is not the case.

To see if you can connect to the cellular network, please refer to this Getting started guide about flashing the at_client sample with LTE Link Monitor.

If you use that in combination with LTE link monitor application provided in nrf Connect for desktop, you will be able to see which networks are in your area, connect to the network, as well as status for the modem etc. through AT-Commands.

Yes I am using the nrf91DK I have followed the instruction but with the lte link monitor I am not able to connect to lte even using the sim included. Each AT command is not working and is giving back timeout errors

Please confirm that you are running the at_client sample when using the LTE Link monitor as the Getting started guide suggest.

A quick tip could be to try the reset button on the nrf91 DK so you get the bootup in the terminal.

Then you follow it by sending the AT+CFUN? to the device.

Please attach the log/screenshot if you stumble upon any issues,

Hi yes that was the problem, just the last question, to turn on the LTE how should I do? I have the LTE grey, i have searched for some networs using AT+COPS? and a network showed up but its status is forbidden. I have tried to turn on the roaming using AT+CIND=1,1,0 but nothing changed even after rebooting. Is it the right way to do it ?

Cheers

Hi Damian,

If you are running the at_client sample, you should only need to send AT+CFUN=1 to turn on the modem. The AT commands are documented in the reference manual.

or even easier send the AT+CFUN? command in LTE link monitor so it will run through a script which sends several AT commands to get out the information about the modem and the network.

Please provide the log in your next post if you have any additional questions.

ok i got the esim working but i need to set a specific apn but using the command AT+CGDCONT=1,'IP','NXT17C.NET' it returns me phone failure, I have asked the company which provided me with the esims but they told that is not an esim problem but it is a problem of the sdk, what should I do?

[Martin Lesund]

Please read the AT-Command reference on how to use the AT+CGDCONT.

Following command should work:

AT+CGDCONT=1,"IP","NXT17C.NET"
