I’m over 50 and registered online using a Portuguese mobile number on the dedicated webpage for those without an NHS/SNS number. No problem!
Except...no SMS or telephone call ever comes to schedule the vaccination day and time. I’ve physically gone to vaccination locations in Aljezur and Lagos to try there and been turned away with a printout of the URL to the site I already registered on weeks ago. Meanwhile, those in lower age brackets who have an SNS number are being vaccinated without delay.
