3G-WiFi trick

[emiinn]

Is there an app that tricks the note 3 that it's on Wi-Fi while it is on 3G or LTE?

For what purpose?

My homephone and internet provider has a app to call after 4 o' clock free to number in Europe inclusive gsm numbers.

I'm using ios right now, and i've got a jailbreak app that tricks my phone it's on wifi while it is on 3G

Is there anyone who can help me?
