For those who don’t know, here are the steps:
1. Connect your BlackBerry 7100 (BB 7100) with computer through USB cable.
2. Activate the Blackberry Handheld Manager and or Blackberry Device Manager (Depends on the Blackberry software version) and make sure the status is connected to the device.
3. Open Device Manager. Expand Modems and double click on Standard Modem.
4. Go to advance tab, add extra initialization command +cgdcont=1,”IP”,”your_apn_name” (depends on your network provider).
For example I put; cgdcont=1,”IP”,”satelindogprs.com” for Indosat Network. Sometime you may have to put a different format such us; +cgdcont=1,”IP”,”satelindogprs.com”,””,0,0
5. After that, do a test query on your modem. You should see what type of modem, Research In Motion, etc.
6. Create a new Internet Connection. On number to dial type in *99#. Leave the password and username blank.
7. Last, depends on the Network Provider, you may have to enter the DNS server IP on TCP/IP Property. In my experience, most of the time leaving the DNS setting to be automatic should be fine. Confirm with your Network Provider about the IP or if you find any difficulty connecting to the Internet.
8. Dial the newly created connection and have fun trying.
