Hi, we are trying to decide on a Portuguese SIM card we can buy so we can receive SMS from Portuguese utility provides while we are in the US. We wont be using these for calls and will just limit the usage to get SMS for verification services while we are outside of Portugal. It needs to be a Portuguese number. Thank you.
Lyca mobile is great
Generally most people use whatsapp over here and some companies do as well. I have had no issues with NOS SMS service over here though I did with my American sim.
I use Vodafone
