voip alternative like fongo or hangout dialer

[ndondo]

Hi,

Often i misplaced my phone.and when that happen i go to my android tablet and use fongo or hangout dialer to locate my phone.

Now i have lumia 640 that i use like ipod (wifi only without sim card)

Is there a good alterative in windows 10 mobile that can do what fongo or hangout dialer can?

Thx u

I dont need to get a local phone number like fongo does ..but at least the ability to call phone number

Skype does this but it carries a fee. I am looking for something free and for casual use

Thx
