Privacy is the default here

In short

SimVala is built so your connectivity is not tied to your identity. You pay in crypto with no card and no ID, your login is an account number we store only as a hash, and we keep no name and no email. Here is exactly what we store, how it is protected, and how to keep your side safe.

Your data

What we store, and what we never hold

The most private system is the one that never holds your data in the first place. This is the complete list.

What we keep

  • Your account number, as a one-way hash only
  • Your balance and top-up history
  • What you bought, so we can deliver it
  • The on-chain transactions you sent to our addresses
  • Identity documents only where a country requires them for a specific order

What we never hold

  • Your account number in readable form
  • Your name, email, or phone number
  • Card or bank details, since we take crypto only
  • A billing address
  • Your wallet keys or seed phrase
  • Your real number on the apps you verify
Your login

How your account number is protected

Random and long

Every account number is 24 characters drawn at random, about 120 bits of randomness. It is shown to you once, when it is created.

Stored only as a hash

We run it through SHA-256, a one-way function, and keep only the result. When you log in, we hash what you type and compare. The number itself is never saved.

A signed, locked-down session

Once you log in, your session is a cryptographically signed cookie marked httpOnly, so scripts on the page cannot read it, and secure, so it only travels over HTTPS.

How hard is it to guess one?

There are about 1.3 × 1036 possible account numbers. At a billion guesses a second, finding one would take roughly 40 billion billion years, about three billion times the age of the universe.

SHA-256, the same one-way function our server uses
What we store

…

Change one character and the hash changes completely, and there is no way to turn a hash back into the number. This demo runs only in your browser; nothing is sent.

The trade-off, honestly

Because we never store your number and there is no email on file, a lost account number cannot be recovered. That is the price of an account nobody can link back to you. Keep it in a password manager.
Payments

How payments stay safe

No card data, ever

We do not accept cards, so there is no card number to store, leak, or be charged against later.

Your keys stay yours

You send from your own wallet to the address we show. We never see, need, or ask for your keys or seed phrase.

Prices set on our server

Every price is calculated on our server when you buy. The page never sends a price, so it cannot be tampered with in the browser.

Monero for private payments

Monero hides the amount and the addresses on chain by default. It is the most private of the nine coins we accept.

On the site

No trackers watching you shop

No tracking scripts

No analytics, advertising, or tracking pixels are added to the site.

Functional cookies only

Just what the site needs to work, like your session and language.

Servers in Germany

Our servers are in the EU, with Cloudflare in front, like most of the web.

Your side

Four habits that keep you safe

  1. 1

    Save your account number safely

    Store it in a password manager. It is your only way in, and it cannot be recovered.

  2. 2

    Never share it

    Anyone who has your account number can use your balance. Support will never ask for it.

  3. 3

    Match the address and network

    Send crypto only to the address on the payment screen, on the exact network it names.

  4. 4

    Treat QR codes and numbers like keys

    Do not post screenshots of your eSIM QR code or your virtual number's codes.

Scams

How to spot a fake SimVala

We never ask for

  • Your account number
  • Your seed phrase or private keys
  • A payment outside the checkout

The only real address

Log in and pay only at simvala.com. Check the address bar before you type your account number.

The only support contact

Support is [email protected]. Send your order details, never your account number.

Security and privacy: FAQ

Does SimVala require ID?+

No. There is no ID to top up or buy. A document check applies only to certain regulated products in a few countries, and only for that specific order.

What data does SimVala keep?+

The minimum to run your account: a private account number stored only as a hash, your balance and top-up history, what you bought, and the on-chain transactions you sent us. No name, no email, no card, no billing address.

How is my login protected?+

Your account number is 24 random characters, about 120 bits of randomness, and we store only a SHA-256 hash of it, never the number itself. Your signed-in session is a signed, httpOnly cookie that scripts on the page cannot read.

Can you recover my account if I lose the number?+

No. Because we never store the number itself and there is no email on file, a lost account number cannot be recovered. Keep it in a password manager.

Do you use trackers or analytics?+

No. We do not add analytics, advertising, or tracking scripts to the site, and our fonts are self-hosted. We only set functional cookies, like your signed-in session and language.

Can I pay with Monero?+

Yes. Monero is accepted alongside Bitcoin, Ethereum, USDT, USDC, Solana, BNB, TRON, and Polygon. It offers the strongest on-chain privacy of the coins we take.

Will SimVala ever ask for my account number or seed phrase?+

Never. Support only needs the order details shown in your dashboard. Anyone asking for your account number, seed phrase, or private keys is trying to scam you.

Where are your servers?+

In Germany, inside the EU. Like most of the web, traffic reaches us through Cloudflare, which provides the secure connection and protection against attacks.
