Hello,

I’ve a problem with Start bearer [AT+WIPBR=4,6,0].  
In my own country (Netherlands), everything worked fine with an Amercan AT&T card (with roaming).

Now I’m in America, and I get “+CME ERROR: 812” after “AT+WIPBR=4,6,0”.  
The description of this error = “bearer connection failure: GPRS network failure”

Can someone help me out, on how to solve this?  
Do I need some setting within the modem?

I use the modem Q2687 (band is set to 900E/1900 MHz)

Thanks,  
Sander

In America, you want 850/1900 MHz (AT+WMBS=4,1).
