Skype vs Threema

What Skype is

Skype was Microsoft's consumer internet calling, video meeting and messaging service. It is no longer an active product choice: Microsoft retired free and paid Skype on May 5, 2025 and stopped selling paid Skype features to new customers. The replacement path was Microsoft Teams Free using Skype credentials, with eligible contacts and chats transferred. The final Skype Export Portal request deadline was June 15, 2026, and Microsoft warned that deletion of older inactive history began April 1, 2026. Skype for Business was explicitly outside this consumer retirement announcement and must be assessed separately.

What Threema is

Threema is a Swiss secure-messaging family rather than one subscription. Threema Private is a consumer mobile app that can be purchased directly for Android for a current one-time price of $7.49, €6.49 or CHF 5.99 and can create an identity without supplying a phone number or email. Threema Work adds annual per-user licensing, a management cockpit, app configuration, optional Broadcast and Gateway components, and a 30-day trial for up to 30 users. Threema Gateway is a separate credit-based API integration. Apps are open source and communications use end-to-end plus transport encryption, but server code and the operating environment are separate trust and audit scopes.

Choose Skype if

• Historical product comparisons
• Auditing whether a former Skype account was migrated to Teams Free
• Documenting legacy calling subscriptions or number-porting follow-up

Skip Skype if

• You are choosing a current consumer messaging or meeting platform
• You expect to create a new Skype paid account, Credit balance or calling subscription
• You assume old Skype history is still exportable after the published deadline

Choose Threema if

• Individuals wanting a paid messenger without mandatory phone-number identity
• Organizations centrally configuring encrypted mobile communication through Threema Work
• Systems sending transactional Threema messages through a deliberately selected Gateway encryption mode

Skip Threema if

• A free consumer messenger with a large existing contact network is the priority
• Enterprise selection is based on the consumer one-time price
• Identity lifecycle, device backup, administrator visibility, Gateway keys and annual renewal have not been tested

Skype: pros & cons

• The historical service combined chat, voice, video and phone-network calling under a widely recognized identity.
• Microsoft provided a Teams Free migration path using existing Skype credentials.
• Remaining paid users were given Dial Pad access through the Skype web portal and Teams Free during transition.
• A documented export process existed before the final 2026 deadline.
• Consumer Skype has been retired since May 5, 2025 and cannot be selected for a new deployment.
• Paid Skype Credit, calling subscriptions and Skype Numbers are no longer sold to new customers.
• The June 15, 2026 export-request deadline has passed; unavailable or deleted history cannot be assumed recoverable.
• The retirement notice does not cover Skype for Business, so the two products must not be conflated.

Threema: pros & cons

• Messages, calls and files use end-to-end encryption with keys tied to a randomly generated Threema ID.
• Consumer identity can be created without making a phone number or email mandatory.
• Open-source apps and published security material provide inspectable implementation evidence.
• Threema Work adds centralized configuration and deployment, while Gateway supports programmatic messages.
• Private, Work, Broadcast, Gateway and OnPrem have different licensing, administration and deployment boundaries.
• The $7.49 figure is a direct Android consumer license, not a Threema Work enterprise seat or iOS universal price.
• Work contracts are annual, prepaid and auto-renew unless cancelled at least 90 days before term end.
• Gateway Basic mode lets the server handle encryption and private keys; true E2E mode requires correct client-side key operations.
