iPhone SE 2nd gen Unlocked now $127 on Amazon - I sell quite a few on my affiliate store :) — Apple iPhone SE (2nd Generation), US Version, 128GB, Black - Unlocked
can even do eSIM - I also sell those too eSimplanet :) I like Maya mobile 5Gb UK for about $9. No need to mess with Android - that would suck! We use them every year and last year I splurged with an unlimited data for about $50. Used to like Airalo but they suck now.
For calls now Skype is dead use Google Voice. And if you want to be especially carful you use an alternative iCloud account.
