GCF settings – Applicability

Some phone models requires GCF settings to be applied in order to complete the unlock, below is the list. You may also need to use this feature in order to open the service menu. To access it you can either tap on “GCF Settings” button on the main screen (Fig. 1), or access such setting from the three dots menu button on top right of the app and then tapping on “GCF Setting” menu item (Fig. 2).

Please follow these steps only if you will use a GSM SIM (e.g. T-Mobile, AT&T etc…), in case you will use another CDMA SIM (like Verizon for example) then skip these steps.

If you applied GCF Setting and you want to revert it in order to use a CDMA SIM (to return back to Sprint for example) just follow the same steps but chose “GCF OFF” or “SETTING CANCELLATION” instead in the latest selection.

If your phone needs the GCF settings to be applied please open such menu using one of the two below ways (Fig. 1 or 2).
