SIM card issue - no SSL

Arduino Uno + SIM900
Software serial connection


Background:

Hi - I made a thread the other day about not being able to connect to the blynk server. After the modem init, it would just keep repeating:

connecting to "blynk-cloud.com:80"

without ever connecting. I couldn’t get it to work, so I went back and learned all about AT commands and whatnot, then ran them through the monitor to try to set everything manually to make http requests via gprs.

I found that my SIM card (Telcel, Mexico) does not have SSL. As in, if I do the command AT+HTTPSSL=?, I am returned this:

+HTTPSSL: (0-1)

It’s my understanding that it should just say HTTPSSL: 1 if it’s equipped. I tested it out by running a regular HTTP connection and receiving packages successfully, then an HTTPS and getting a 601 error.


Question:

Is it possible that the reason I can’t make a GSM connection with the blynk-cloud is because my SIM card doesn’t allow SSL connections? Is there any way around this?

SIM card has nothing to do with SSL. This is SIM900 that does not have SSL support.

Does SIM900 not support SSL even with firmware updates? I am having AT+HTTPSSL=1 set and connecting to https it wont work, but change to AT+HTTPSSL=0 and connect to http and it will work
