I have an unlocked Android Samsung Galaxy S20 FE 5G phone. It does not support eSim but will work fine with a physical SIM card. I would appreciate any recommendations for SIM cards available for a tourist which can be purchased in Spain upon arrival in Seville.

I will be coming from the US, but it appears to still be difficult to purchase a SIM card prior to arrival. I have done this many times successfully but found that buying it locally in Spain is much easier overall.

Any recommendations for a carrier that will work in Spain? I will also be in Lisbon for a few days at the end of our trip, it would be good if I could use it there as well. My understanding is that in most cases within the EU that SIMS from major providers should work in both countries.

Thanks in advance for your advice and recommendations.
