How To Check Your Mobile Network Coverage
It’s not unreasonable to expect decent mobile network coverage in your area. Whether you’re using your mobile phone for work, or you want to be sure that you’re getting the best signal quality possible from your monthly phone plan, you can use various tools to check network coverage in your area. We take a look at how to compare mobile coverage in the area you are living in, or moving/travelling to. In doing so, we’ll also show you how to use a speed checker and a postcode checker to test your coverage, and help you to make sense of the outcomes.
Understanding Network Coverage
Like any form of technology, mobile comes with its own set of technical terms. Before we dive in, it’s important to understand all of the crucial lingo surrounding the topic. Reading through our handy glossary of terms below will make understanding mobile network results that much easier:
- Download speed: the rate at which data is transferred from its source to your mobile device. Some examples of functions influenced by download speed include streaming songs or videos, browsing the web and receiving Whatsapp messages.
- Upload speed: The upload speed is the rate at which data can be transferred from a user’s mobile device to the internet. For most consumers, download speed might be more important than upload speed, however those who want to upload content like social media posts quickly will value this.
- Latency: the term that refers to the delay between information originating at the network transmission end and when it arrives on a mobile device.
- 2G, 3G, 4G & 5G: The generation of mobile networks. The G stands for generation and the higher the number the more recent the generation. 5G has launched in the UK, and the new network promises much faster upload speeds (especially in crowded areas), however more research is needed into the current level of coverage.
- Geographic coverage: The level of coverage across the UK landmass.
- Population coverage: The percentage of UK inhabitants that have sufficient signal to connect to a particular mobile network.
- Availability: The proportion of time mobile network users experience a certain level of connection on a mobile operator’s network. Unlike geographic or population coverage, availability measures how often users can access a particular network, for example the 4G network.
What can affect network status?Network signal can go down for multiple reasons, including maintenance work or extreme weather damage. Most providers have a status checker through which you can search for updates about service interruptions in your area.
Network Speed Checker
Telecoms regulator Ofcom provides an impartial tool to test the speed of mobile and broadband connections. The great news about this speed checker is that it’s very easy to use - all you need to do is press the button that reads start test. Once your speed checker results are ready, your download, upload and data delay statistics will appear in the details tab on your screen. The speed checker also gives you the availability of a number of common internet uses at the time of testing, including:
- Web browsing
- Online gaming
- Internet phone calls
- Video calling
- Video streaming (HD)
- Video streaming (4K)
Network Postcode Checker
Most leading mobile networks offer a service through which you can check the level of coverage in your current location, postcode or place name. Usually these services take the form of a handy interactive map on a provider’s website.
Ofcom offers a useful tool that helps you check mobile coverage across any network in areas where you live, travel or are moving to. The tool shows where coverage is likely to be available and how reliable it will be by drawing on Ofcom research into the signal strength needed to provide a high quality connection.
- Head to the Ofcom mobile and broadband checker.
- Enter the postcode you wish to search for or press the upwards facing arrow to share your current location.
- Click on the button that says check postcode.
You’ll receive results for voice and data coverage by mobile operator, topographical information allowing you to identify areas where there are natural obstructions to coverage (like valleys and hills), as well as indoor and outdoor coverage levels. The results are colour coded, with red representing a lower probability of coverage and green a higher probability.
Different signal strength for different generations of networkDid you know that any given location will receive different signal strengths depending on whether your device is connected to the 2G, 3G, 4G or 5G network?. When you use a postcode coverage checker or coverage map make sure you look for the generation of network you are after.
The Network Providers
All mobile phone signal in the UK is provided by only four mobile network operators. These four providers own the entire mobile network infrastructure of England, Scotland, Wales and Northern Ireland - on which all other mobile carriers ‘piggyback’ for coverage. These other mobile carriers are piggybackers or MVNOs (mobile virtual network operators). If there is an issue or outage among one of the four network infrastructures it will affect the mobile carriers that piggyback on their signal.
Vodafone has the second highest geographic coverage of all of the networks with 79% coverage. Vodafone scored 87% for customer satisfaction with signal strength in Ofcom’s 2018 report, coming in at the industry average but behind the EE network.
You can use the Vodafone network status checker on their website to check coverage in your area by following the simple steps below:
- Head to the Vodafone network status checker page.
- Enter your postcode (or the postcode you are searching for) into the search bar or click on the compass signal to share your current location and click the search icon.
- You’ll then see your results showing the quality of coverage received across the 2G, 3G, 4G and 5G networks. There is also a distinction between outdoor and indoor coverage the level of strength will show up as either good indoors & outdoors, good outdoors only, limited coverage or no coverage.
