I am pretty low tech but was successful in switching my sims card in Colombia in 2017 for 3 weeks when I had Verizon. Now we have Consumer Cellular as a carrier and I believe that the phone is unlocked. We will be in Portugal for 7 weeks, Ireland for 3 and Iceland last week. Since Ireland is not in the EU is there any way to get one sim card that would work for all 3 countries? Due to my lack of knowledge I am not sure what would be the best option to text, call and have data. I noted that Vodaphone has 30 day plans that could be continued but not sure about how to do that with a non EU country. We could get a cheap phone just for Portugal but I am not sure that would help. We won't need much in Iceland because we are traveling with family.
Thanks for any assistance in figuring this out from those with more knowledge in this area. Input is greatly appreciated.
