Check Mobile Phone Coverage

Prior to ordering a SIM only contract it is important to consider not only the actual specifics of the deal on offer such as free minutes, free texts, unlimited Internet, etc but also whether the phone network you have chosen will provide you with the best mobile phone reception available in your location. Before committing to buy a SIM only deal it is possible to check the mobile phone coverage in your area by using a network coverage checker. Each mobile phone network offers an online network coverage checker which you can use by entering the postcode of your home or workplace onto the web page and the graphic will tell you whether the mobile signal will be strong from that particular network in the given area.

The coverage between mobile phone networks can vary greatly even within a short radius so it is definitely worth using the network coverage checkers because it has been known for reception to be excellent in one area and 500 metres away, the same network records a poor signal. In addition to checking the signal strength from home it is also worth checking the signal strength at places where you will commonly use your phone such as your workplace or friends and relatives homes.

How to Use Online Phone Network Coverage Checkers

Although you would assume that it is easy to use the online mobile phone signal strength checker tools, each tool is provided by a different network so they work in subtly different ways.

Why Is There Poor Mobile Phone Reception In My Area?

There are a variety of reasons why you may not be able to get a good reception in your area.

Important aspects to be considered are the quality of your phone antenna or whether you are indoors. For details on how to increase your mobile phone signal indoors see our guide. One of the biggest reasons for poor phone reception is how far you are from your phone network operators nearest phone mast. The further you are away from the phone mast, the weaker the phone signal which will mean an increase in the likelihood of dropped calls or even a lack of network coverage entirely.

Some networks share masts to increase the network coverage nationwide and you can find an interactive map showing the locations of the phone masts operated by the respective mobile phone companies via the website.
