Rent a number for Proton Mail
Rent a number to register with Proton Mail
The irony of Proton Mail is that a private mail service asks for a phone at the door: a free mailbox is not issued without human verification, and of the available methods SMS goes through more reliably than the rest. The number does not become part of the address and is not visible to correspondents. We rent physical numbers on real SIMs.
How Proton Mail checks the number
Verification here is one-off: Proton checks that a human is registering and does not bind the number to the account unless you add it as a recovery method yourself. Because of that a short rental is enough for Proton — unlike mail services where the phone remains the key. The form rejects virtual ranges: that is exactly what it is there for.
