How to Switch Between CDMA and GSM Networks on Sprint’s BlackBerry Bold 9650


As mentioned before, the BlackBerry Bold 9650 from Sprint comes factory unlocked and it can operate on Quad-band GSM/GPRS/EDGE networks, Single-band UMTS/HSPA networks or Dual-band CDMA/EVDO REVA networks. So you can either use it on CDMA carrier or GSM carrier. CIO’s @ASacco has put together a great, quick walkthrough on how to switch between CDMA/1XEV and GSM/UMTS networks. Here are the steps for your reference:

How to change the BlackBerry Bold 9650’s mobile network technologies between CDMA/1XEV and GSM/UMTS.

  1. Ensure an active and compatible SIM card is inserted in your BlackBerry Bold 9650 SIM card slot. (To insert a new SIM card, remove your Bold’s battery cover and battery, take out the default SIM supplied by Sprint–if applicable–then slide the new SIM into place based on the diagram on the SIM-card slot.)
  2. Replace your Bold’s battery and wait for the device to reboot. When your Bold is up and running, click your BlackBerry’s Manage Connections icon on your home screen.
  3. Within the Manage Connections menu, scroll down to and click Mobile Network Options. On the following screen, scroll to Network Technology and click to open a drop-down menu. Then change the value from either Global or 1XEV to GSM/UMTS.
  4. Exit out of the Mobile Network Options/Network Technology menus, wait a few seconds for the new network connection to establish itself and you’re good to go.
  5. To switch back to your CDMA network, simply repeat the above process but choose the 1XEV network option under Network Technology.
