[Skunkworks] Orange Modem Error 619

Hi Skuks, I have a modem that is not locked and works with Airtel and Safcom without any problem. Putting in an Orange SIM card, it can detect the network and show the bars, when doing the Authentication, it does not succeed instead it brings up the error 619. The Settings are APN: bew.orange.co.ke Access Number:*99# dint work i put *99***1# which also did not work User name: blank Password:blank Any one who knows the work around or solution for this? Regards Joe
