Poor mobile coverage can have many causes. Here are the most common ones:

Building materials

Some materials can block or weaken mobile signals, for example:

• concrete

• insulation

• metal

• energy-efficient windows

This can cause your phone to lose signal indoors.

Distance from a transmitter

If you are far from the nearest mobile transmitter, for example in remote areas:

• the signal may be weaker

• the connection may be unstable

Terrain and weather

• mountains, hills and valleys can block signals

• severe weather can sometimes have a temporary impact

Devices and settings

Your connection may be affected if:

• your phone is old

• the software is not up to date

• network settings are incorrect

• the device does not support 4G or 5G

Interference in your surroundings

Equipment near you can affect the signal, for example:

• faulty or misconfigured equipment

• devices that do not meet regulatory requirements

If your mobile coverage is poor, you can try the following:

• try Wi‑Fi calling

• check your settings and software

• view coverage maps for your area

• contact your telecommunications provider

• submit a report to the Electronic Communications Office if you suspect interference
