SMS Anonyme or encrypted messaging?

Two ways to protect your communication, for two different needs.

Back to the comparisons

SMS Anonyme and encrypted messaging apps (WhatsApp, Signal) protect your communication, but not in the same way: one hides your identity for a one-off send, the other encrypts the content of an ongoing conversation. Here is how to choose.

The head-to-head, criterion by criterion

CriterionSMS AnonymeEncrypted messaging (WhatsApp, Signal)
Sender anonymityHidden number: the recipient does not see your numberYour number (or ID) is visible to the contact
Content encryptionNot encrypted end to end (like any SMS)Encrypted end to end
Account / appNone: nothing to installAccount and app required on both sides
The recipient must be equippedNo: received on any mobileYes: they must use the same app
Recipient's replyNo reply back to you (hidden number)Continuous two-way conversation

In conclusion: which one to pick?

Choose SMS Anonyme for a one-off contact where the point is not to reveal your number, without an account or installation. Prefer an encrypted messaging app like Signal for an ongoing conversation whose content you want to protect — provided your correspondent also uses it. The two are complementary rather than competing.

Your most frequently asked questions

Q01Is an anonymous SMS encrypted?

No. SMS is not encrypted end to end: avoid putting sensitive information in it. The anonymity applies to your number, not to the content.

Q02Do WhatsApp or Signal hide my number?

No. These apps encrypt the content but expose your number or ID to your contact. To hide your number on a one-off send, SMS Anonyme is better suited.
