Any of the three main providers (MEO, Vodafone and NOS) should work as long as you make sure that 1. you top up BEFORE leaving Portugal so you have enough balance to make calls and 2. it's a regular voice, text and data SIM card. It's a matter of which option gives you the most for your money so read each provider's section carefully. Good luck and have a nice trip!
