Hi! I’m trying to estabilish a connection but I keep receiving “no network service” for AT!SCACT=1,1 command. I’m sending the following commands in order:

> [@](#):

> AT!ENTERCND=“A710”  
> OK  
> AT+CPIN?  
> +CPIN: READY
> 
> OK  
> AT!CUSTOM=“IPV6ENABLE”,1  
> OK  
> AT+CGDCONT=1,“IPV6”,“zap.vivo.com.br”  
> OK  
> +CGDCONT: 1,“IPV6”,“zap.vivo.com.br”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0
