Hey guys

I have a SIM5218 from cooking Hacks:
**broken link removed**

and I am using the developer SIM Card from at&t:
**broken link removed**

I am wondering if anyone ever has this type of error:?

Code: 
$ AT+TCPWRITE=56
AT+TCPWRITE=56
 * sendCommand timeout
$> AT+TCPWRITE=56


+IP ERROR: Network not opened



ERROR


$ AT+TCPWRITE=56
AT+TCPWRITE=56
 * sendCommand timeout
$> AT+TCPWRITE=56


+IP ERROR: Network not opened



ERROR

Thank you

Rosty, I never used this model but the message says you don't have a connection to send these commands. Usually you need to "start network", maybe "Acquire client resource" commands before send and receive commands.
