Depending on your network, some providers will give/sell you a device to
route calls through your own broadband via a picocell.

My sister has one as her house is in a mobile phone €œnot-spot€� with
abysmal
signal strength on all networks.

If your network doesnt have such devices, change to one that has.

Now that many phones support calling over Wifi the picocell offerings
have become redundant. You might still get one second hand though.

You might, though it may be difficult/impossible to register it with the
mobile network (They need to know where it is, so it selects the right
Tx frequencies for your district).

The best solution is to select a network and phone that support WiFi
calling, some networks require you to have bought the phone from them,
others, (EE and Sky) don't care, if the phone supports it, it should
workÂ* .
