In the past I’ve travelled using that other card (Revolut) but as I live in the Channel Islands it was blocked 6 or so months ago as the CI are not in the EEA.
Does the same apply to Monzo and if it does have you any plans to make the card available to CI residents? An indication of time scales would be welcome.
the most recent thread on the subject implies it is available in the Crown Dependancies, but you could check with @anon38211169 if this is currently the case
