This is very probably due to the device not trusting self signed certificate.

There are workarounds for this (Android or IOS specific) like

http://blog.crazybob.org/2010/02/android-trusting-ssl-certificates.html
http://stackoverflow.com/questions/1217141/self-signed-ssl-acceptance-android
etc.

But all of this required additional implementation and doesn't seem to be very reliable. It makes quite more sense to buy the certificate now and test with that.
