I bought a pack of Vodafone NB-IoT SIMS from Arkessa for use in London, UK as there is currently no LTE-M availability where I live.
Arkessa have provided the following information to enable me to connect.
AT+CGDCONT=1,"IP","arkessalp.com" # define packet domain context
AT+CGAUTH=1,"PAP","arkessa","arkessa" # authentication parameters
I have flashed the Thingy:91 with the latest modem firmware (1.1.1) and also the NB-IoT demo firmware.
Although I can see the Vodafone network in the nRF Connect app, I can't connect to it. Arkessa don't know what the problem is. They suggested that the signal was weak but I drove and sat in my car near to where they told me the Vodafone mast is situated and that didn't fix it.
I have attached a screenshot from nRF Connect and the log.2020-03-13T11_18_46.857Z-log.txt
I also tried just using the AT client firmware, but I didn't get anywhere with that either.
Any suggestions?
