Mine was a Vodaphone SIM.
It's pretty straightforward.
On the first MB screen after inputting your PIN, there are a variety of choices. I believe one of these is "serviços." (I hope
@jungleboy or someone else present can confirm this. I'm working from memory, here in Canada...)
After pressing "services" or the equivalent, you'll get something like this:

Bottom left is "telemoveis," which is mobile phones.
Click that, and it'll give you a list of all the providers in Portugal.
Choose the one you use (Vodaphone for me), and it will ask you for the phone number in question, and how much you want to top it up. Obvious blanks: 9 spaces for the phone number. I guess it assumes it's Portuguese.
It displays both the phone number and the amount input for top-up.
Once you confirm that, about 30 seconds later, you'll get a text notification on your phone that the topup has occurred. A great service!
