How can i change my iPhone 4s CDMA to GSM mode?
 

l have an unlocked iphone 4s from Vodafone uk which is in CDMA mode l want it to switch to GSM mode because l can't request balance even recharging airtime, in fact USSD function are inactive. Also without activating Roaming l can't use internet.

Please help!

VF is CDMA network? Jailbreak if iOS is <7.1. evasi0n iOS 7.x Jailbreak - official website of the evad3rs Open cydia, search for iFile, go back to Manage at bottom in Cydia, click Sources, edit add apt.chinasnow.net. Install commcenter from that source. Open iFile, go to /var/mobile/library/Default.bundle, go to carrier.plist, Property list viewer, and turn SupportsSupplementaryServ to ON. Restart iPhone.

Thank you so much I'll do so and report the results. It's iOS 7.1
