VOXI review 2025: why we're impressed with their network

Having joined VOXI as a real-life customer and used their network, we give our verdict on their 5G/4G coverage, speeds and added benefits. Last updated: 25th November 2024.

Overall rating

SIM Sherpa rates VOXI as a very good provider
 (3.5/5, very good)

“We have actually had to downgrade our review score of VOXI since they ditched inclusive EU roaming but there is still plenty going for them. Not least their brilliant Unlimited Video streaming benefit.

The basics of any network are excellent too. VOXI have decent data speeds and excellent overall coverage, though their 5G rollout needs to hurry up a bit to keep up. WiFi calling and 4G are good too.

People will really value the lack of any commitment on their SIM only plans too and that you don’t need to undergo a credit check to join VOXI. It means they’re accessible basically to anyone.

One bugbear for some people might be the lack of any telephone-based customer service or some of the more niche network features but it’s all baked into the price. We’d join VOXI over Vodafone any day of the week.”

The 3 best bits

1 Unlimited Social Media on all plans
2 5G coverage on all plans
3 Only ever a 1-month commitment

The 3 worst bits

1 No more inclusive roaming
2 Online-only customer service
3 No app

Why is VOXI for under 30s?

It’s not any more. Any age can join VOXI. It was originally launched by Vodafone to target this age group, which would not normally become Vodafone customers - with benefits that would appeal to younger users like Endless Social Media.

Do you have to be a student to use VOXI?

No. They’re now open to anyone. They used to have a maximum 30 years old age limit. But this is no longer the case.

Is VOXI fast?

It can be. It depends where you are and what technology you’re using. We’ve clocked over 70 Mbps in cities but about a tenth of that in the country.

Is VOXI 5G-ready?

Yes. 5G is now live on all VOXI plans, including SIM only and phone contracts for models which have 5G as a feature.

Is there an app for VOXI?

No. There’s no app. You have to sign in to your online account. In there, there are some limit settings you can adjust.

Can I bring my old number to VOXI?

Yes. It works in the usual way. Text PAC to 65075 from your old SIM. Your old provider will give you a code. You then give this to VOXI, who will arrange for you mobile number to be moved across to them.

Can you join VOXI from Vodafone?

Yes. And you may even be able to do it without ordering a new SIM. Just order your plan from VOXI’s website and you’ll be able to choose that you’re an existing Vodafone customer.

VOXI's network reviewed

Coverage is a strength of VOXI, particularly for 4G

VOXI 4G and 3G coverage map

Identical signal to being on VodafoneCheck signal near you

(opens in new window)

VOXI were set up by Vodafone and are owned by them. So their network coverage is identical. We’ve actually physically tested two SIMs against each other to make sure. It’s even a Vodafone-branded SIM you receive.

While we can’t check every inch of the UK’s landmass for signal, we did some spot checks in different locations. We tested our VOXI SIM in the same phone and places as our Vodafone SIM to check for any differences.

We got the same number of signal bars in the same areas on both networks. We found no differences in coverage between them and everything suggested they share identical call and data signal.

In urban areas, we were consistently on 4G and even superfast 4G+ signal in some areas. And we managed to 4G in some surprisingly rural locations.

We were able to connect to call signal in the middle of our house and it was basically impossible to lose signal entirely, short of going underground.

Overall, we think most users will be happy with the excellent mix of coverage that VOXI offer.

It means VOXI customers enjoy the joint best 4G data coverage in the UK. And we’ve always found it impressive how you can still have usable 4G even rurally on VOXI. In urban areas, it’s even rarer to be without it.

5G is more of a work in progress. VOXI actually have the smallest number of live 5G locations in the UK at 318. We’ve found this only tends to be an issue if you’re somewhere busy like an event, competing for a signal.

VOXI’s hosts have switched all their 3G call signal masts over to 4G and are in the process of doing this for their 2G ones too. This will inevitably leave some holes which 4G hasn’t yet patched over.

If you’re on a newer device you can use VOXI’s widespread 4G to make calls, but users on 3G/2G-only phones won’t be able to make calls at all. In any case, check signal near you here before you decide.

Data speeds are a big upside of being on Vodafone’s network

Faster 4G+ signal in urban areas

VOXI’s network hosts have put a lot of effort into increasing 4G speeds and our real life tests showed this. We got speeds as high as 100+ Mbps over their faster 4G+ signal, but speeds will depend per location.

In rural areas speeds crawled down to 5 Mbps, but most of the time we sat around a healthy 25-30 Mbps. That’s backed up by independent network testers Opensignal’s result of 31.1 Mbps on VOXI’s hosts.

While we can’t test data speeds in every part of the country, we did some tests in different areas to see what speeds look like in real life and how Opensignal got their results.

There were no speed limits being on VOXI vs Vodafone, which we confirmed by testing both SIMs using the same device. Speeds weren’t absolutely identical, but weren’t different enough to call one faster or slower.

In the city centre, we managed to get up to 100+ Mbps over 4G+ signal, which even rivals home fibre broadband. But speeds will slow down as you move out of the centre, even down to around 6 Mbps - 8 Mbps.

Right out in the countryside speeds crawled to 5 Mbps. As such we can see how it all averages out to get Opensignal’s result. Speeds can either race ahead or slow to a crawl depending on where you use your phone.

That puts VOXI in joint-second for 4G speeds. And it’s the same story for 5G, with excellent typical speeds between 138.7 Mbps - 162.63 Mbps according to Opensignal and Speedtest and impressive peaks of 354.83 Mbps.

They’re not the fastest for 4G or 5G, but offer very healthy speeds over both. They’re great for streaming on the go, which pairs nicely with their Unlimited streaming data benefits. In all, speeds are a strength.

WiFi/4G calling is useful if your phone is compatible

While VOXI’s call signal is good at getting indoors, you may still find blackspots if there are obstructions between your home and the mast. VOXI let you call over WiFi instead of call signal to help with this.

You also get 4G calling, which you can use to call over VOXI’s widespread 4G instead of traditional call signal. This will be crucial for calling once 2G is entirely gone (check if your phone is supported here).

We tested VOXI’s WiFi/4G calling as soon as it came out in order to see how well it works as a feature and how it compares to Vodafone’s.

In terms of functionality, our tests found that VOXI’s WiFi calling was effectively the same as Vodafone’s, with no huge differences between them. That was the case for 4G calling as well.

And we’re sure VOXI support the same devices to Vodafone as they link directly to Vodafone’s website. In all, it’s great that you don’t get a worse experience on VOXI vs being on Vodafone directly.

VOXI also let you text over WiFi/4G and calls made over WiFi can be transferred over to 4G without dropping. VOXI’s WiFi calling is up there with the best schemes in terms of how it actually functions.

The worst thing about VOXI’s WiFi calling is that they don’t support as many Android devices as some providers, so you might struggle to get it to work on some older models. But overall it’s a great feature.

(opens in new window)

VOXI let you tether your data signal to other devices such as laptops or other phones that have run out of data. They let you use up to your entire data allowance, even on their unlimited data plan.

Visual voicemail is also supported on VOXI, letting you sort through your voicemails one by one and display them in the order you received them. They’re one of just two small networks to let you do this.

They haven’t included any free WiFi hotspots for a while now. They used to and it’s a shame they got rid of them as they’re great for saving data and staying connected in places you’d otherwise get no signal.

VOXI don’t let you forward incoming calls to a different number either. And there’s no way to join VOXI on an eSIM, which you can do on Vodafone.

VOXI benefits

Unlimited Video is the best of VOXI’s many benefits

VOXI Endless Video

Stream video without using up dataRead full terms

at VOXI.co.uk
(opens in new window)

VOXI include benefits that “zero-rate” your data usage for certain activities. Their Unlimited Video benefit is very generous as it lets you stream these apps without eating up your data on VOXI’s higher end plans.

Their mid-range plans include Unlimited Music, that lets you stream on Spotify, Apple Music and these other music apps without using up your data. This can save you a lot if you listen to music quite often.

The last of these benefits is Unlimited Social Media that lets you use these social media apps without using up your data. The data savings will be relatively low, but it comes on every plan which is very generous.

On top of that, VOXI give you rewards for bringing friends onto their network. You’ll both get a £10, £15 or £20 Amazon voucher when you refer a friend to VOXI. In all, VOXI are very generous for a smaller network.

VOXI offer some other handy benefits too

VOXI capped contracts

You’ll pay only for what you useHow payment works

from VOXI's help section
(opens in new window)

VOXI’s deals are similar to other networks’ PAYG monthly bundles. Think of it like topping up your SIM with an allowance of mins, texts and data to use up in a month. This type of deal has a few upsides:

Because you’re not stuck on a contract you can switch or leave your plan when you want. Just turn off “auto-renew” and let your plan run out. After that you’re totally free to switch.

And as you’re not joining on a contract you won’t need to pass a credit check to join VOXI’s SIM only plans. And to use any extras you have to top up with credit first, so there’s no way to accidentally overspend.

VOXI offer International Minutes Extras which include 100 mins to these countries for £3 a month, which works out cheaper than a lot of other networks. And their data add-ons are good value at £3 for 1GB.

The biggest benefit you miss out on with VOXI is data rollover, which usually lets you hold onto your unused data for a month. And there’s no family plan scheme like SMARTY’s 10% off extra deals on your account.

No inclusive EU roaming is a big drawback on VOXI

VOXI endless roaming banner

Talkmobile do include EU roamingSee all destinations

at talkmobile.co.uk
(opens in new window)

One notable downside of being on VOXI is that you don’t get EU roaming included on your plan, instead you have to pay to use your plan there. Talkmobile are on Vodafone’s network and offer EU roaming on all plans.

You have to pay for every day you use your VOXI SIM abroad, or you can take their temporary roaming passes. You can pay £2 a day, £4 for 2 days, £8 for 8 days or £15 for days. Those are your only choices.

But VOXI’s Global Roaming Extras are actually good for going beyond the EU. These give you a small amount of mins, texts and data for 8 or 15 days. It’s a decent choice compared to what most networks offer.

But overall we can’t imagine regular roamers will want to bother with having to pay extra to go to the EU. In that case you’d be better off on another provider that does include EU roaming (read our guide here).

VOXI won’t stop you from joining based on your age

VOXI age limit

You may have heard that VOXI used to prevent anyone over the age of 30 from signing up to their network. However, these restrictions are long gone now, so anyone can join VOXI these days.

We’re not certain if VOXI removed these restrictions because they were accused of discriminating against customers by age or just wanted to sell to more people. Either way there are no restrictions on this anymore.

If you want to join on a phone contract you will have to be 18 or over as you’re joining on a credit agreement via Paypal Credit. But they won’t stop you from joining them if you’re over 30.

VOXI already draw in loads of young customers who wouldn’t otherwise join Vodafone. And with these age restrictions gone, VOXI has become an even more popular network.

VOXI offer very flexible contracts based on finance

Phone contracts from VOXI

They offer all the latest modelsSee the full range

at VOXI.co.uk
(opens in new window)

VOXI’s phone contracts split the cost of your phone into smaller monthly payments over an agreed period of time. The longest contracts they have go up to 36 months with their shortest ones being 12 month contracts.

This gives you the flexibility to suit your contract to your needs and your budget. And as they’re based on finance, you can pay lump sums to reduce your monthly bill or pay off your loan to upgrade early whenever.

Your monthly bill is made up of two separate payments, one for your phone and the other for your usage plan (mins, texts, data). This means you can switch or leave your usage plan while still paying off your phone.

But passing a credit check will be more difficult than on traditional contracts and missing a payment will massively affect your credit score. Still, if you can get one, VOXI are a great choice for phone plans.

VOXI customer service

VOXI don’t offer many ways of getting help

League table of complaints data

Ofcom don’t have them in their reportRead Ofcom's report

VOXI are one of the many budget networks who keep costs down by not having call centres. They do have an online chat, but it’s hard to get through to a real person and the chatbot is a bit frustrating to use.

The easier way of getting in touch with a real person is via their social media accounts. While this is a decent option, we’ve found it can take a while for them to respond.

We can’t use Ofcom’s complaint record to say how good they are at resolving customer issues as they don’t show up in it. This is due to them being too small or because they’re not technically a pay monthly network.

If VOXI offered over-the-phone service it would give customers another way to get help, instead of waiting for an agent to respond over chat. As it is, VOXI are the worst network for customer service in our eyes.
