SIM card support outside of regions

Question

Hi there, 
 
 We're working with a Nordic nRF9160 DK and are trying to get access to the network in both Spain and in Ireland. In both cases, the iBasis SIM won't work in these regions. We have requested a SIM through Vodafone and in the process they have asked for which IP addresses that Nordic has opened up for 'whitelisting'. Do you know if there is a range of IP’s that nrfcloud uses that we could whitelist to get the demo up and running? Possibly some endpoint that the device reaches out to? 
 
 Thanks for your support! 
 Best regards, 
 -Paul

Paul, 
 we run our infrastructure on AWS in a serverless fashion which does not allow us to use dedicated IP addresses. However the IP address ranges AWS is using is published here: https://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html - you could use this list to configure the firewall. However I do not advise this approach since it means that the list has to be monitored for changes.
