WiFi Calling (VoWiFi)

WiFi Calling (VoWiFi) lets you make and receive calls over your WiFi network when there is no mobile coverage. It is a fully legal solution that needs no signal emission or permits, and is often free: you just need a compatible phone and operator.

It is the best alternative for rural homes, basements and areas where amplifying the outdoor signal is not viable. We check compatibility, optimise your WiFi and leave calls working reliably.

WiFi Calling (VoWiFi) shines exactly where repeaters fail: in rural homes, basements, storerooms and areas where the outdoor mobile signal is practically nil but internet does reach (fibre, radio link or satellite). Instead of trying to amplify a signal that does not exist, your calls travel over the WiFi network to the operator network.

It is a fully legal solution —it emits no signal and needs no permits— and with most Spanish operators it is free: you just need a compatible phone and plan. That is why, before proposing a more expensive installation, we always assess whether WiFi Calling solves your problem.

For WiFi Calling to work well, the WiFi network must reach with good quality every room where you want to talk. We check your home or premises' WiFi coverage, detect weak spots and, if needed, improve the network with access points or mesh systems so calls do not drop.

We also confirm your operator and devices support VoWiFi, enable the feature correctly and make test calls in the problem areas. That way you can be sure the solution really works before the job is considered done.

This is the limitation worth knowing before choosing WiFi Calling as your only solution. The call travels over your WiFi while you are within range; when you step into the garden or the street, the phone has to hand it over to the mobile network, and if there is no coverage there, there is nowhere to hand it to and the call drops.

Inside the property, handover between access points can be solved properly, and that is where a well-built network shows: points sharing the same network name, non-overlapping channels and power levels set so the phone switches in time. That is exactly the work we do when optimising WiFi for calls.
