Cannot receive SMS running sample sms

[LuRocm]

I built the SMS sample without changing anything. I am using a Lebara prepaid sim card. I was able to exchange SMS messages from one cellular phone to another. I checked with the sample at client in case a pin is necessary.  This is not the case according to the response of AT+CPIN

What I am missing?

[Einarh]

Hello!

It seems like you are not able to reach the network and end up in the network timeout in the connect_lte function.

Do you know if there are any restrictions on what your type of SIM card can be used for?

If your prepaid SIM can only be used to send SMS, I am not sure how the application would handle that.

One thing you could try is to enable CONFIG_LTE_NETWORK_USE_FALLBACK in prj.conf, to make the application try different modes instead of giving up after the timeout.

You can also change the value of CONFIG_LTE_NETWORK_TIMEOUT to test with different timeout durations.

Best regards,

Einar

Hello 

I appreciate your help. The prepaid SIM is for voice and data. I have done what you suggested. It did not work out. Therefore I run at client sample to help identify the problem. The at client can not also connect to the network.  The LTE is blinking Yellow the whole time without ever connecting. Could you send me the technical specification of the iBasis sim so that I can send it to phone company? The iBasis sim is able to connect to the network. Is there a possibility to supply the pin code for the SMS sample? 

Best regards

Martin

Hello

I tried the sms sample with a SIM other than iBasis today (Telenor), and was able to send and receive sms messages without having to supply a pin code.

Since you are still getting timeouts when attempting to connect to the network, it seems like your problem has to do with your SIM.

Have you tried using the nRF Connect LTE Link Monitor to observe the state of your device? It makes it very easy to monitor your network connections while you're running the AT client for example, and might make it easier for you to figure out what isn't working.

I'm not sure what you mean by technical specs for the iBasis card other than what you can find on their website?

I'll be on holiday from next week, but there will be other people in the office who can help you if you're still having problems.

Best regards,

Einar

Hello, I found out what the problem was and fixed it. The AT+COPS  response had the value Forbidden for the operator. The SMS application was only able to find this one operator. Therefore I got a sim of this operator and deactivated the request for the pin code.
