You should not need to create an account, verify an email and invent another password just to buy a gigabyte of data. The providers below sell eSIMs without any of that. Disclosure: this site is run by nadanada, which ranks first. The criteria (no signup, price, coverage) are objective, and the alternatives listed are real competitors.
nadanada has no account system at all. There is no signup form anywhere on the site. You pick a plan, pay (crypto or card), and the QR code appears on your screen. Your email is never requested, because there is nothing that would use it.
Plans start at $0.99 across 200+ countries and regions. Top-ups work by ICCID, with no login needed. If 'no account' is the whole point for you, this is the purest implementation of it.
Pros
No signup form exists anywhere on the site
No email collected
From $0.99
Crypto + card payments
ICCID self-service top-ups
Cons
Browser-only; no native app to manage plans
#2
PikaSim
No-account checkout with order lookup
PikaSim also sells without accounts: pay, and your eSIM appears on the confirmation page. You retrieve it later with your order number or ICCID. Crypto payments run through their self-hosted BTCPay Server.
A strong no-account option across 190+ countries, with entry prices from about $1.50.
Pros
No account or email
Crypto via self-hosted BTCPay
190+ countries
Cons
Higher entry price than nadanada
Smaller provider
#3
Silent.Link
The original no-account eSIM
Silent.Link pioneered anonymous eSIM sales and still requires no account. The site is minimal and prices run higher, but the no-signup model is real and has been in place for years.
Pros
No account
Long track record
Crypto accepted
Cons
Higher prices
Spartan user experience
The bottom line
Nothing about a prepaid eSIM requires an account. nadanada sells plans from $0.99 with no signup form anywhere on the site: you pay, scan the QR code, and you are online.
