Sunrise number

I have recently signed up a contract with sunrise, wherein I get to call sunrise numbers for free .. I forgot to ask the guy how to recognise sunrise numbers .. can anyone please help ?

Sunrise numbers start with 076.

But since numbers can be ported when changing providers, nowadays you can't rely on that.

You will hear a "warning tone" when you dial a non-Sunrise number. It's a low-hi tone repeated once.

Sunrise reseller number's also begin with 076.

My Sunrise subscription with free calls to Sunrise does not provide free calls to a reseller like Yallo which also begins with 076. Not sure of to Lebara 076 though.

You can check who the cell phone provider is by entering the following:

*109* cell number #

example: *109*0767654321#
