  1 4 10.0 Java

  MHC (ME-Https-Client) is a J2ME library written in Java which offers an alternative implementation for the javax.microedition.io.HttpsConnection interface.

One problem though: Your phone may or may not allow HTTP(S) connections (especially on ports < 1024) for unsigned/selfsigned apps. And: The certificate store of these old phones are hopelessly outdated, so you will have a hard time connecting e.g. to a server with a Let's Encrypt certificate. One solution is to use a custom HTTPS-library with its own certificate store. Maybe this helps: https://github.com/baumschubser/mhc
