To disable the secondary Modem NAI, go to Menu > Settings > Display, and press 0 to access a hidden menu. Enter 040793 as the security code. At the following menu, scroll to Toggle NAI and chose Off Modem NAI, followed by OK. Then power the phone off immediately. When you turn the phone back on, Modem NAI will be disabled.
its amazingly fast man OMG... after you do the above step then you can use the #777 and it works great
It is amazing....once I figured out that I had to disable Bluetooth in order to enable modem mode. COOL! Thanks again for your help. Yes, I know it's "old school", but still works.
LOL. I'm such a NOOB. Once downloaded dialing software all came together but still wouldn't "Go" until disabled BT.........then "wheeeeee". I know this is "old stuff" to you guys, but never needed it until changed phones and found could no longer go online with SnapDialer. Old Sanyo 6200 worked but didn't have BT. Katana wouldn't work. Checked and found A900 still worked so bought used. A900M won't work. Sprint figured out quick after release A900 and D/C'd it. Thanks again....
