I will be coming to Portugal (Lisbon) in September to study, but I don't yet speak Portuguese (I am hoping to learn it in time). I could hardly get to this forum using Google Translate, so I appologise if your website already contains answers to my following questions :)
1) Is it possible to get a SIM by post or do I have to visit one of the MEO branches? If I have to visit a branch, what is the closest one to Lisbon Airport?
2) Is it possible to top up the SIM online using a credit card? If not, where can I do that in Lisbon?
