It is really a good access source to ensure good broadcasting performance. The exact command is really important to be able to activate the modem.

scratch games, thanks!

Before trying other areas for coverage you could try to actively search and list your available cell towers with "AT=COPS=?". This will take some minutes but returns a list of all your sourrounding cells which you then can verify with https://www.opencellid.org and with that you verify your hardware is working, which cell towers you could connect to and ask your provider about further support as you can tell them which cells you try to use.

On my nrf9151 i got connection problems too and resolved it by turning all search functions off and after that activate the modem with CFUN=1, as any search disabled the modem from connecting to a cell. Maybe there is a active search running in the background?

You can look for further informations and error path in my other ticket: devzone.nordicsemi.com/.../540255

Hi,

While the SIM card should be supported in the UK, how good the coverage is may still vary. The EMM causes listed here also gives the impression that you do not have coverage there. Could you try a different area? Contacting the provider to check if you have an active service and data is also an idea.
