Error + HTTPACTION: 0.601.0

I am trying to access a website using the sim900 GSM module. This is a list of commands.

AT+CSQ      
+CSQ: 16,0          

OK  
AT+HTTPINIT           
OK  
AT+HTTPPARA="CID",1                   
OK  
AT+HTTPPARA="URL","www.google.com"                                  
OK  
AT+HTTPACTION=0               
OK  

+HTTPACTION:0,601,0                         

AT+HTTPACTION=0
OK

+HTTPACTION:0,601,0

Unable to access Google. 601 shows a network error. How to get rid of this error?

You need to configure the connection to the channel. Here are the minimal setup commands that worked for me (based on trial / error and search on the web).

AT+SAPBR=3,1,"APN","wap.cingular"
AT+SAPBR=1,1

The correct value for APN may vary for you, depending on your network and service provider. I use AT&T prepaid SIM cards. After that, you can execute the HTTP configuration commands, as you already ...

AT+HTTPINIT
AT+HTTPPARA="URL","http://www.google.com"
AT+HTTPACTION=0

I could connect to the network, but when I tried to use HTTP over GPRS networks, I received a return code of 601 (network error) or 603 (DNS could not be resolved).

As soon as I replaced the antenna with a new one, everything worked perfectly.

Change the URL. 601 - URL has been moved. Is a redirect.
