The registration screen opens, the number can be entered (including the +423 prefix) but the registration then times out, waiting to receive a message. After the time out, when selecting the \"call me\" option, no call goes through.\r\n\r\nI assume this is a limitation on the servers end that does not allow calls/texts to Liechtenstein to go through. I assume that reversing the direction (i.e., the phone calling the Signal server to get the code) would not work as an attacker could spoof his/her phone number.\r\n\r\n### Steps to reproduce\r\n- Install Signal on Android phone\r\n- Use Liechtenstein SIM card (country code +423)\r\n- Try to register.\r\n\r\n**Actual result:** Registration times out, call fallback does not go through (i.e., no incoming call is received). Interestingly, registration with an earlier phone and the same SIM card/number worked ~1.5 years ago.\r\n**Expected result:** Either a registration text message should be received or after the timeout a call should come in.\r\n\r\n### Screenshots\r\n<!-- you can drag and drop images below -->\r\n\r\n\r\n### Device info\r\n<!-- replace the examples with your info -->\r\n**Device:** Nexus 5X\r\n**Provider:** Telecom FL\r\n\r\n### Link to debug log\r\n\r\nRegistration fails, so submission of debug log is not possible as the settings cannot be opened.\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/WhisperSystems/Signal-Android/issues/comments/203922420","html_url":"https://github.com/WhisperSystems/Signal-Android/issues/5384#issuecomment-203922420","issue_url":"https://api.github.com/repos/WhisperSystems/Signal-Android/issues/5384","id":203922420,"user":{"login":"anoncoward","id":18190484,"avatar_url":"https://avatars.githubusercontent.com/u/18190484?v=3","gravatar_id":"","url":"https://api.github.com/users/anoncoward","html_url":"https://github.com/anoncoward","followers_url":"https://api.github.com/users/anoncoward/followers","following_url":"https://api.github.com/users/anoncoward/following{/other_user}","gists_url":"https://api.github.com/users/anoncoward/gists{/gist_id}","starred_url":"https://api.github.com/users/anoncoward/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/anoncoward/subscriptions","organizations_url":"https://api.github.com/users/anoncoward/orgs","repos_url":"https://api.github.com/users/anoncoward/repos","events_url":"https://api.github.com/users/anoncoward/events{/privacy}","received_events_url":"https://api.github.com/users/anoncoward/received_events","type":"User","site_admin":false},"created_at":"2016-03-31T12:57:10Z","updated_at":"2016-03-31T12:57:10Z","body":"Same problem here: Czech Republic (+420)\r\n\r\nIt has worked without problems in the past."}}
