This is a cool service that I came across and used. Pretty legit and neat.
You buy a prepaid prefunded visa card from here, then redeem it here. They'll provide you with a virtual CC number, expiry date, and CCV to use anywhere! I don't think it's anything new, but to be able to purchase this with lightning is pretty cool !
I've been looking for a good burner phone service with lightning, found two but they use voip numbers that can't be used for accounts verification. Got me this visa card and bought a real sim card number delivered via email. This is great, really:)
