a workaround could be using amazon prime + prime lockers (1-2 day)

sign up for amazon prime (or know someone with it)

Get 10-20 of these, delivered to a prime locker near you in 1-2 days. pick it up, should last you a while?

(bestbuy/some pharmacies sells them too, probably not as cheap)

I do see bestbuy automated kiosks at some airport locations, they probably have (overpriced nontracfone) prepaid sims too
