Standard home phone calling charges apply. If the person calling you is in the same local calling area, they will be charged at the local calling rates (i.e. a free local call). So if you are both in the same local calling area you can call each other for free in the same way all home phone customers currently do - whether fixed line or wireless.
If the person calling is outside your local calling area, they will be charged at the applicable rate (i.e. a toll call). If the person calling receives their service from another service provider, their standard calling rates will apply. The toll call rates from different service providers vary. It would be best for the person calling you to check with their service provider in order to be certain what the call charges will be.
Calls to and from your Home Phone Wireless connection are treated as landline calls so the charge should be the same whether they are calling you, or a landline in the same location.
