EC25 failing to connect with new SIM/network

IoT Modules LTE Standard Module
1

Hi,

I have been using an EC25 module with a Raspberry Pi 3B+ and successfully connected to the internet via wwan using an 02 sim. Now I’ve changed the sim to a vodfone uk one, updated the APN details being passed however connection keeps looping without successfully connecting.

I’ve checked using AT+COPS? and the correct network is returned. I’ve been passing both wap.vodafone.co.uk and pp.vodafone.co.uk as my APN name however both fail to get a connection. The sim is a store bought pay as you go SIM.

Here is the log which I get when trying to connect:

This continues indefinitely and the module never gets a connection. Any help greatly appreciated…

Thanks,

Peter

Now resolved.

I was using a bash script to pass the APN detials to ‘./files/quectel-CM/quectel-CM’ - for some reason old APN details were neing picked up. When I manually cd in to this folder and ran the file with the new APN details, everything worked.

Subsequently I re-ran the exact same script (with the new Vodafone APN details) and the device connected as expected…
