My wife and I will be visiting Madeira for 3 weeks in March. We both have unlocked U.S iPhones. We would like to swap out our existing sim cards for ones we can use while we are in Madeira. The sims should include 10-20gb of data with unlimited local calls and texts.
There are some available here in the U.S from Amazon including one for the Three (3) network. I’m not concerned about being able to make international calls back to the U.S while we are there. Can anyone recommend a good sim card that would work well in Madeira. If we can’t purchase it in the U.S before we leave, we have a 4-stop over in Lisbon airport if there are any retailers there we could use.
Any recommendations would be appreciated.
