Your phone number is one of the strongest identifiers you have — it ties together accounts, location and contacts. Getting a number or data plan without registering your identity is harder than it used to be in many countries, but several routes still work.
1. Privacy eSIMs for data
If you mainly need mobile data, an anonymous data eSIM is the cleanest option. Silent.link sells global data eSIMs for crypto with no name, email or document required, delivered instantly. It is ideal for travel and for keeping your data connection separate from your identity.
2. A real number paid with crypto
For calls and SMS, JMP.chat gives you a real phone number that you use over the open XMPP standard, paid in Bitcoin, Lightning or Monero, with no identity at signup. Crypton.sh offers numbers controlled from a web dashboard and paid with crypto, handy for receiving the SMS codes that services insist on.
3. Second-number apps
MySudo gives you multiple working numbers, email aliases and even virtual cards under separate "identities," so you can compartmentalise rather than spread your real number everywhere. It is paid through the app store rather than crypto, so it trades some payment privacy for convenience.
What about physical SIMs?
Prepaid SIMs bought with cash still exist, but registration rules vary widely by country — many now require ID at activation. If you go this route, check local rules first, and remember that the network still sees the device's location regardless of how the SIM was bought.
Choosing by use case
- Just need data: a privacy eSIM like Silent.link.
- Need to receive SMS codes: a crypto-paid number such as JMP or Crypton.sh.
- Want everyday separation: a second-number app like MySudo.
One honest caveat
No phone service is magic. The mobile network can still see where a device connects, and any account you log into with the number can re-identify you. Use these tools to reduce unnecessary linkage, not as a guarantee of total anonymity. And follow the law where you live — some jurisdictions require SIM registration.
