Threema Messaging and Call Incident Checks

Isolate the failing Threema communication path

Check the Threema status page to compare activation, message delivery, calls, media, and backup reports.

• Test send and receive directions separately.
• Compare Wi-Fi and mobile data behavior.
• Record country, device, version, and symptom.

Do not publish Threema IDs, private messages, backup passwords, contact lists, or media contents.
