VOXI 4G Coverage and Network Review

4th February 2019

VOXI coverage

VOXI is a mobile virtual network operator (MVNO) powered and run by Vodafone. That means wherever Vodafone has signal, VOXI will too. Specifically, that currently means that VOXI has at least 99% UK population coverage with 4G.

But it stands out from Vodafone – and other UK networks – in a number of key ways, most notably the fact that you can use most popular forms of social media without eating into your data allowance.

Here’s a full overview, review and guide to the network.

VOXI Coverage

Network Type

Coverage by population







As VOXI uses Vodafone’s infrastructure it has the same coverage as Vodafone, and that’s no bad thing, as Vodafone's network offers 99, 99 and 99 per cent 4G, 3G and 2G population coverage respectively.

While that’s behind EE and Three, it still means you’ll be able to get coverage almost everywhere and in most cases you’ll be getting fast 4G. You can expect coverage to rapidly improve too.

VOXI (Vodafone)






4G from Vodafone (and by extension VOXI) is now available in around 1000 larger towns and cities including but not limited to:

Basingstoke, Birmingham, Bournemouth, Bradford, Brighton, Coventry, Dudley, Edinburgh, Epsom, Ewell, Folkestone, Gateshead, Glasgow, Hatfield , Hove and Hastings, Hemel Hempstead, Huddersfield, Jarrow, Leeds, Leicester, Liverpool, London, Manchester, Maidstone, Newbury, Newcastle, Nottingham, Oldham, Pontefract, Portsmouth, Reading, Rotherham, Sheffield, Slough, Stockport, Sunderland, Sutton Coldfield, Staines, Stourbridge, Swinton, Southampton, Tunbridge, Wakefield, Walsall, Watford, Wells and West Bromwich.

Vodafone and VOXI’s 4G service is also available in thousands of smaller villages and other communities across the UK. Recent locations to get a 4G upgrade include: Preston in Dorset, while Camberley in Surrey recently got improved 4G.

Network Speeds and Frequencies

VOXI uses standard 4G, which is around 5 times faster than a typical 3G network.

VOXI (Vodafone)






VOXI’s network hasn’t been studied much, but Vodafone’s has and is likely to be similar, since they share infrastructure.

According to an OpenSignal report from October 2018 (above), Vodafone achieved average 4G download speeds of 21.92Mbps. That puts it behind EE but ahead of Three and O2.

Its average latency (how long the network takes to respond to a request) on the other hand is 40.78ms, which beats out any rival other than EE.

VOXI (Vodafone)






Speedtest also looked into the major UK networks, and found Vodafone to have an average download speed of 17.26Mbps, which is second best, though also factors in 3G speeds. Vodafone’s average upload speed is also second best, at 8.16Mbps. As such VOXI should also be quite fast.

Band 20



Band 8 2G & 3G

Band 32



Band 3



Band 1


2600MHz FDD

Band 7


2600MHz TDD

Band 38


Vodafone (and by extension VOXI) uses the 800MHz, 1400MHz and 2600MHz bands for 4G. The 800MHz band is long range and good at penetrating walls and other solid objects, which makes it useful in both rural locations (where there aren’t many masts) and more built up areas.

But it doesn’t have the available capacity of the 2600MHz band, which makes the latter better for busy areas with lots of simultaneous connections. The 1400MHz band sits in the middle in terms of strengths and weaknesses. For more in depth information, check out our 4G frequencies guide.

Planned improvements

VOXI’s improvements will depend almost entirely on Vodafone, but there is some news there, as Vodafone has announced that it's planning to share 5G infrastructure with O2 (just as it currently shares some 4G infrastructure). Of course, Voxi may not get 5G at the same time as Vodafone, but whenever it does launch a 5G service it sounds like it should be in a solid position. Vodafone has also started installing 4G antennae under manhole covers to improve coverage.

Traffic management

VOXI’s traffic management policy is the same as Vodafone’s, and the network notes that “during busy periods on our network we may need to manage traffic to ensure everyone has access to our services.”

It may also block or throttle your data in the event of activity that’s harmful to the network, but otherwise speeds should be unrestricted.


VOXI offers three SIM-only plans. The network also offers a small selection of smartphones that you can get on any of these three plans.

All of VOXI’s plans last just 30 days, so you have the flexibility to change or cancel them whenever you want. That's true on both Pay Monthly and SIM Only (which have the same selection) though on Pay Monthly you will have to pay off your phone over 30 months. Plans also all come with unlimited minutes, texts and picture messages.

The main highlight of them though is the ability to use Snapchat, Instagram, WhatsApp, Facebook, Twitter, Pinterest, Viber and Facebook Messenger as much as you want, without it eating into your data allowance. That includes voice and video calls. The only requirement is that you have some data left, but if you run out you can buy a 1GB add-on for £3.

VOXI also has passes which allow for unlimited data use on select music and video services. The video pass lets you use unlimited data for Netflix, YouTube, Amazon Prime Video, Disney Life, My5, TVPlayer and UKTV Play, while the music pass includes Spotify, Tidal, Deezer, Amazon Music Unlimited, Prime Music, SoundCloud, Napster and Apple Music.

VOXI also allows you use as much of your data as you want for tethering on all of its plans. Another perk of VOXI is that if you get a friend to join you’ll each get a £10 Amazon gift card.

Data Only Plans – For Tablets and Dongles

VOXI doesn’t offer any data only plans, however you’re free to use their SIM cards in the likes of tablets, so you can always sign up for a standard plan.

Pay As You Go

VOXI doesn’t currently offer any Pay As You Go services.


Tethering is allowed by VOXI, with the only data restriction being your own data allowance. That means you can use your phone’s mobile data connection to get other devices – such as tablets – online. You can also use the endless social data and any other endless data passes you have when tethering a phone, laptop or tablet. However, tethering a console, TV, Chromecast or the like will cause data to come out of your normal allowance.

WiFi Calling

Wi-Fi Calling isn’t supported by VOXI. It’s a service that allows you to call and text seamlessly over Wi-Fi, so you can keep talking when there’s no mobile signal. We’ll update this page if VOXI ever starts offering it.


VoLTE, aka Voice over LTE or 4G Calling, isn’t offered by VOXI. As the name suggests, it means being able to call over 4G, rather than 2G or 3G, and as with Wi-Fi Calling the main advantage is that it means you essentially have signal in more places. We’ll let you know if VOXI ever starts offering this.

Roaming Destinations

VOXI lets you roam at no extra cost in the following 48 European destinations:

Austria, Azores, Belgium, Bulgaria, Canary Islands, Channel Islands, Croatia, Cyprus, Czech Republic, Denmark (including Faroe Islands), Estonia, Finland, France (including Corsica), French Guiana, Germany, Gibraltar, Greece, Guadeloupe, Guernsey, Hungary, Iceland, Ireland, Isle of Man, Italy, Jersey, Latvia, Liechtenstein, Lithuania, Luxembourg, Madeira, Malta, Martinique, Mayotte, Monaco, Netherlands, Norway, Poland, Portugal, Reunion, Romania, Saint Martin, San Marino, Slovakia, Slovenia, Spain (including Balearic Islands), Sweden, Switzerland, Turkey and Vatican City.

Customer service

There isn’t much information on the quality of VOXI’s customer service, but it’s run by Vodafone and there are some reports on that network.

According to an Ofcom complaints report from 2018, Vodafone has more complaints than any network other than iD Mobile or Virgin Mobile, at 9 per 100,000 customers. This is however a slight improvement on a previous Ofcom report.

Things don’t look any better in the Which? H1 2017 UK Mobile Network Survey, which asked 4,026 people for their opinions on mobile networks and found that Vodafone was rated worst, with a customer score of 50%.

The report additionally gave Vodafone 2/5 for customer service, ease/speed of contacting and value for money, and 1/5 for incentives. So that doesn’t bode well for VOXI’s customer service.

VOXI itself meanwhile is rated 5/10 on Trustpilot, which equates to 'average'. That's with 100 ratings at the time of writing.


VOXI is a promising, good value network giving you a lot of flexibility. Its main strength is social media and instant messaging, since you can use them without delving into your data, but the availability of free roaming and tethering also makes it competitive with other networks.
