Don't forget about WiFi coverage

Of course it's great to get a much faster broadband connection. But naturally you'll want to make sure you can take advantage of this throughout your entire home or business.

If your property is larger or has thicker internal walls, in order to ensure good connectivity in every room you should definitely consider extending your WiFi coverage.

So don't fix your incoming broadband just to be irritated by still having WiFi dead spots - discover how to extend your WiFi coverage here.

Frequently asked questions

The Connecting Devon and Somerset Mobile Boost Voucher Scheme has been put in place to help small businesses and households who currently have poor indoor mobile coverage.

It aims to upgrade indoor 4G coverage within homes and businesses in order to improve connectivity and provide the ability to make and receive mobile phone voice calls.

The scheme focuses on household and small business connections and is targeting those premises which have no adequate 4G indoor coverage from either no operator or only one operator.

You can find more detail on the CDS Mobile Boost Voucher Scheme by visiting the Connecting Devon and Somerset website.

You should be eligible if you live or work in Devon or Somerset and the mobile phone signal is too weak indoors where you are to allow you to reliably make or receive mobile phone calls.

However, the only way to find out if you're eligible is to apply, which is a very quick and simple process. If you're not eligible, Connecting Devon and Somerset will let you know why in its response to your application.

Because mobile phones can also use an internet connection to make and receive calls. This means that, even if you’re out of range of mobile signal, if your handset is connected via WiFi to good quality broadband, you’ll still be able to make and take mobile calls. This ability is known as WiFi calling.

For this to work, both your mobile phone and the mobile operator you have your phone service contract with must support WiFi calling. These days, almost all mobile phones and operators do, but it is important that you check this out first.

Under the CDS Mobile Boost Voucher Scheme, all the costs of getting set up with our fast 4G broadband service will be fully covered.

So the only costs you’ll pay are the monthly subscriptions for the 4G broadband plan you choose.

All our new customers get the complete peace of mind offered by our no risk 14 day satisfaction guarantee. This means that if for any reason at all, you’re not entirely satisfied with our 4G broadband service, just let us know within the first 2 weeks. We’ll then immediately cancel your contract with us with no ongoing liabilities or commitments whatsoever.

Then just return our router to us within 45 days and upon receipt, we’ll issue you with a full refund of all your set-up costs. No quibbles, no questions asked.

That’s a good question – after all, the whole reason you’re applying for a CDS Mobile Boost voucher code is because your mobile phone doesn’t work reliably inside your property. And yes we do use 4G as transmitted by the mobile networks to deliver our broadband service.

But don’t worry. We’ve got years of experience in getting our customers set up with speedy and stable 4G broadband, including in places where mobile phones only show very flaky signal – or even no signal at all.

Remember, we have relationships with the majority of the UK’s mobile network operators, so we can – and will – always pick the best choice of 4G network for your particular location. What’s more, the small but highly effective outdoor 4G antenna that we’ll supply and fit is far better at receiving 4G signals than any mobile handset.

So that’s why we should be able to provide you with perfectly good broadband over 4G where you are. Don’t be fooled by what your mobile phone’s telling you!

It's just not possible to be sure what 4G broadband speeds you’ll get at your property, because performance depends on so many factors unique to each location.

That’s why we always refer to the average speed that our customers experience, when measured across the entire UK as a whole. This is around 25 Mbps, which is more than sufficient for any typical internet-based activities including streaming of HD video and of course, WiFi calling. This has been independently audited and verified, as you can see for yourself by viewing this Opensignal Mobile Network Report.

We have plenty of customers all over the UK who get 4G broadband speeds significantly faster than that. And of course, because it’s an average figure, we have others whose 4G broadband doesn’t quite reach that level, but who are still delighted with our service, because it’s so much of an improvement over the broadband they get down their landlines.

What’s more, unlike many other alternative broadband services, the speeds we provide over 4G are never throttled - so all your data is always transmitted at the fastest rates available.

As with any broadband service, actual performance depends on many factors, such as overall demand on the Internet resource being requested and network congestion at the time.
