The way OWS designed TS, it requires Google account and Google Play / Apps to use the data channel. This build, at least, will/should work with SMS only mode. Warning, it's an old build. Want up to date builds? Ask moxie why OWS only distribute anti-surveillance software builds though a known NSA asset.

Two days ago, I downloaded it despite the browser warning the certificate was not valid: "[2]ngrok.com:61924 uses an invalid security certificate. The certificate is not trusted because it is self-signed. The certificate is only valid for isadora-amd64 (Error code: sec_error_unknown_issuer)" I installed TextSecure on my Droid 3 which does have a cellular account. TextSecure works if airplane mode is not on. Turning airplane mode on and wifi on, TextSecure does not work. Yet, description of TextSecure is that it works over wifi, data and/or SMS. I installed TextSecure on my Motorola droid 4. I use Droid 4 as a PDA. No cellular account. How can I get TextSecure to work over wifi? Thanks.
