FAQ

All of your frequently asked questions answered.

The public / private keypair is stored within our secure database servers, there are two asymmetric keys, master and encryption. The master key is used to encrypt your encryption key while the encryption key is used to encrypt any data you have. We do not have access to either of them as your passphrase is required to decrypt. You can retreive them by downloading your data in the dashboard.
You're right, nothing and nobody can be trusted, however we have made our best efforts be as transparent as possible and have therefore released our user encryption module source code on GitHub, you can access it by clicking the icon in the footer. The general rule is that you shouldn't provide any information you wouldn't want to be leaked.
No, while we make sure to encrypt any data stored on our servers / infrastructure, data is not being encrypted as soon as it exits our systems onto the GSM / CMDA network.
Anything you want really, if you need to create a second account on Signal, Telegram, Whatsapp or any other service that requires a mobile phone number. You can even use it with social networks to stop them selling your data to advertisers. You can use it to message friends or relatives if you need to.
You can receive and send messages from any country available in our helpful message pricing box. Basic rule is that most countries will work perfectly fine, on some sent messages however your number may be replaced with a "SMS" contact, in those cases we include your number at the end of the message.
Nope, as far as we are aware no incoming/outgoing messages are blocked and no filtering is taking place.
Most of the information we store is encrypted with your private key, only some metadata (such as dates) remains unencrypted. We do recommend you use an email that cannot be traced back to you.
We will comply with any lawful search warrant, however due to our security practice our canary, which you can find in the footer, will not get updated.
Nope, even if we wanted to, we could not, we only know when they arrive but not much else.
Please do not use Crypton.sh for evil things (or harm anybody for that matter), we would appreciate not having police coming over.
At the moment we only offer phone numbers from the United Kingdom, and we have now started testing SIM cards from other, mostly european countries, so keep and eye on updates :)
Yes, our service is available over TOR, you can find the link in the footer.
Nope, as soon as a number is expired it is removed from the pool and SIM card physically destroyed.
Yup, all real SIM cards that are put into our bespoke modems (we even have our logo imprinted on the boards).
eSIM (embedded SIM) data plans are digital SIM cards that you can download directly to your compatible device. They provide mobile data connectivity in various countries without needing a physical SIM card. Our eSIM plans offer instant activation, global coverage, and flexible data options.
After purchasing an eSIM plan, you will receive a QR code and activation instructions via email. Simply scan the QR code with your device's camera (iOS) or go to Settings > Mobile Data > Add Data Plan (Android) and scan the QR code. The eSIM will be installed and activated automatically. You can also use the manual activation code if QR scanning is not available.
eSIM is supported on most modern smartphones and tablets. This includes iPhone XS and newer models, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, and many other recent devices. Check your device manufacturer's website to confirm eSIM compatibility.
eSIM data plans are designed for mobile data connectivity only. They are not intended for receiving SMS messages or phone calls, and therefore cannot be used for TOTP (Time-based One-Time Password) or 2FA verification codes. For verification purposes, please use our physical SIM card phone numbers.
We offer eSIM data plans covering over 190 countries and regions worldwide, including popular destinations in Europe, North America, Asia, Africa, Middle East, and Oceania. Plans are available for single countries, multi-country regions, and global/regional packages.
eSIM data plan validity periods vary by plan. Most plans offer validity periods ranging from 7 days to 30 days, with some plans offering longer validity. The validity period starts when you activate the eSIM on your device. Check the plan details before purchasing to see the specific validity period.
Yes, you can suspend your eSIM at any time through your dashboard. Suspending pauses your data plan without canceling it - you can reactivate it later. You can also cancel your eSIM, which permanently terminates the plan. Note that canceled eSIMs cannot be reactivated and refunds are subject to our terms of service.
Virtual phone numbers are cloud-based phone numbers that are not tied to a physical SIM card. They are provided by third-party services (like Vonage) and can be used for receiving SMS messages and making/receiving calls through our platform. They offer flexibility and can be used from anywhere with an internet connection.
Virtual numbers may work for some TOTP/verification services, but we do not guarantee or officially support this functionality. Some services may block virtual numbers, and delivery of verification codes is not guaranteed. For reliable TOTP/2FA verification, we strongly recommend using our physical SIM card phone numbers instead.
Virtual numbers can be used for receiving SMS messages, making and receiving calls, and general communication purposes. However, they may not work with all services that require phone number verification. They are best suited for general messaging and communication rather than account verification or critical services.

Great Service When Everything Works as Intended. Rented two numbers already as well as had an interaction with support about an issue I encountered. They were very helpful and added a feature to resolve my issue in less than a week.

Customer
Trustpilot

Been using Crypton.sh for a while now and overall it works well. I like the no-KYC policy and the encryption setup feels solid. Setup was smooth and delivery was quick. Support could be a bit faster, but aside from that it's been reliable so far. Good value for the price.
