I will be in Spain, Portugal, Azores

[unableto]

I have a {150 GB Data at 5G Speed} plan.
I am going to be in  Spain, Portugal, Azores for 4 weeks starting Sept 25 2024.
Is there a way to "simply" add an international plan from public so that my phone will work in Europe?
I'd like to send / receive calls and SMS texts with minimal inconvenience!

thank-you.

sorry, even you willing to pay, PM does not have roaming other than US. So, you can't do that

but consider using travel eSIM like Airalo or buy local data sim
