How to configure TinySine 3G module (SIM5320E) for HTTP GET request
CSTT works on GPRS modules like SIM900. I found a way to get SIM5320E working to download websites. Tested with TeraTerm and used &lt;Ctrl M&gt; and &lt;Ctrl J&gt; instead of '&lt;CR&gt; &lt;LF&gt; OR /r/n' characters.

Network setup

AT+CGDCONT=1,"IP","&lt;your APN&gt;","0.0.0.0"
AT+CGSOCKCONT=1,"IP","&lt;your APN&gt;"
AT+CSOCKSETPN=1


Start HTTP service
You can stop and start service if it's not responding properly.

AT+CHTTPSSTART
AT+CHTTPACT="www.iforce2d.net",80


HTTP GET request

GET /test.php HTTP/1.1  &lt;-- don't hit enter, instead hit the below 2 keys
&lt;Ctrl M&gt;
&lt;Ctrl J&gt;
Host: www.iforce2d.net  &lt;-- don't hit enter, instead hit the below 2 keys
&lt;Ctrl M&gt;
&lt;Ctrl J&gt;
Connection: close  &lt;-- don't hit enter, instead hit the below 4 keys. This is useful when connecting to REST APIs to download the the respective result only.
&lt;Ctrl M&gt;
&lt;Ctrl J&gt;
&lt;Ctrl M&gt;
&lt;Ctrl J&gt;


To end the command and to receive results:

&lt;Ctrl Z&gt;


You will receive a lot of data here.

Stop HTTP service

AT+CHTTPSCLSE
AT+CHTTPSSTOP


You will get the contents of the website. Probably it should contain the data you need (I didn't test the content. May be you will need to tweek the result a bit.)
