How easy is to get a prepaid SIM-card in the US for travel? - Sopuli

I’m visiting for two weeks and roaming prices are insane, I’m considering getting a prepaid SIM-card. Can I easily grab one in any shop, e.g. at the airport/Walmart? What are the prices? Unlimited data would be nice, but I can survive with a few GBs too, I’d probably need it mainly for navigation.

Yeah pretty easy dont even need an ID for the majority of states afaik. Not sure about airports but I assume so. Big corpo stores (target and walmart) will have them regardless though so no worries on that. As for prices the cheapest unlimited plan would be like visible at 25$ per month, avoid mint mobile since youll have to pay for 3 months.
Any ideas for T-mobile? It seems that Verizon and AT&T use exotic frequencies for my phone, so maybe that could be the best option, but I don’t know how good their coverage is…
Mint Mobile uses the t Mobile Network. And they have a 7 day trial sim at Best buy for like 2 bucks you could just do two of those since you probably don’t care about having the same phone number for both weeks. The bandwidth is limited though. Or you could get a month off unlimited for like 45 bucks.
