I'm having some trouble getting my GM862-GPS to go online.
I've tested my SIM card in an iPhone 3GS, so I know the data plan is active and working properly. The GM862 connects to AT&T's network, I give it the same APN settings as the iPhone, but I always get an error back after the AT#GPRS=1 command "+CME ERROR: activation failed".
AT#CEER returns "#CEER: 237", which Telit's documentation (along with just about every other GPRS doc I can find) defines as "PDP unsuccessful activation cause SM refuse". However I can't seem to find the acronym 'SM' explicitly defined anywhere. Anyone else had this problem, or know what the #CEER: 237 error code means?
The only solution to "activation failed" I've seen suggested anywhere is to upgrade the GM862 firmware... I flashed the unit with the 07.03.401 and 07.03.402 revisions (hosted on round solutions web site), same behavior on all three (I started with 400). I also sent Telit an email earlier today but haven't heard back yet.
Also, the SIM is basically setup for an iPad or tablet, data plan only.
