The SIM900 has more capabilities than normally advertised, namely SMTP and HTTPS support. To check whether your version of SIM900 supports SMTP, attach a terminal emulator and type in
AT_EMAILCID=?
If the reply ends in OK, you're supported.
This is a work in progress. Currently ASCII mode is supported for Subject and Body. UTF-8 mode is supported but never tested.
Mixing SSL and login names/ passwords with non-alphanumeric characters causes the SIM900 to reset.
Similarily non-alphanumeric characters in https URLs exhibits similar behaviour. I need to fix that so I can develop a Telegram class.
Your testing and feedback would be appreciated.
