Hi I’m using the mangoh yellow to test out the WP7702 cellular modem and I was told that you can make voicecalls with it as well as do SMS. I found the command needed to make a voice call, that is ATD##########; But when I try this command, it says I don’t have a carrier, which makes perfect sense since I never signed up for one. I was wondering if sierra wireless provides that service or if I should get a sim from another company? I noticed it has a sim slot but nothing happens when I insert an active sim card in there. Hope you can help.
So I figured out that the sim slot there is definitely needed to make a phone call or do anything with cellular but for some reason the network will not register. (at+cops?) returns 2 which means its deregistered from the network and (at+cgreg?) returns 1,4. I’m not sure if that’s bad but I think it’s supposed to be 0,1. I’m just wondering what I should do to get it to register to my network. I’m using t-mobile by the way. I read sometimes this just takes time. Could that be the problem?? Let me know if you have the solution!
