5G SIM Only Deals

A 5G SIM Only deal offers you a bundle of minutes, texts and data just like a standard phone contract. But unlike a standard phone contract they don’t come with a handset. They enable you to save money because you don't need to pay for the cost a new phone and they also come on shorter contracts.

Simply order a 5G SIM card and put it into a 5G phone to enjoy superfast speeds when you are in a 5G coverage area.

Which networks offer 5G SIM Only deals?

The only networks currently offering 5G SIM Only plans in the UK are Vodafone, EE, O2 and VOXI. 

BT Mobile also offers 5G, but currently only to BT Plus broadband customers with a 5G phone plan. Three meanwhile is expected to begin offering 5G mobile plans before the end of 2019, and all its current SIM Only plans will be upgraded to 5G at no extra cost. Sky is also set to launch 5G this year (by November) and may well offer 5G SIM Only once it does. All other networks are yet to confirm when they will launch 5G services.

EE

EE currently offers two 5G SIM Only plans, starting at £32 per month and including an unlimited 5G plan which has no speed or usage restrictions.

The 20GB plan includes two swappable benefits and you can choose between BT Sport in HDR, Amazon Prime Video, Roam Further, Video Data Pass, Music Data Pass or Gamer's Data Pass. While the unlimited data plan comes with three swappable benefits, which are BT Sport in HDR, Amazon Prime Video and Roam Further.

Vodafone

Vodafone has also now switched on its 5G network and offers a number of 5G SIM Only plans, including some with unlimited 5G data.

The plans, which start at £11 a month, are available on 12-month or 1-month contracts and all come with unlimited minutes and texts.

The difference between the Unlimited Lite, Unlimited and Unlimited Max plans is the maximum speed offered. The cheapest are Unlimited Lite plans, which offer speeds of up to 2Mbps (good for browsing, social media and music streaming), the mid-range Unlimited plans offer speeds of up to 10Mbps (enough to stream HD video), while the Unlimited Max plan has no speed restrictions (for superfast downloads and streaming in UHD).

Of these Unlimited plans, only Unlimited Max is capable of true 5G speeds, however Vodafone stands out through also offering 5G roaming in parts of Spain, Italy and Germany.

Three

Although Three doesn’t offer a 5G mobile service yet, all of Three's current SIM Only plans are 5G Ready at no extra cost, meaning you can buy them now and you'll be able to access 5G when the network switches on 5G for mobile later this year.

View all Three SIM Only deals

Three’s SIM Only plans primarily stand out through being better value than much of the competition, as well as having an unlimited data option.

O2

At the time of writing, O2 currently just offers one 5G SIM only plan. It’s a 12-month plan with 50GB of data.

We’d expect O2 to launch more 5G SIM Only plans over time, but the one plan currently available at least has plenty of data, plus the standard O2 extras, such as access to O2 Priority for discounts, freebies and early gig tickets.

VOXI

VOXI currently offers just one 5G SIM Only plan but it’s a good one, with unlimited data, minutes and texts.

This plan is just 30 days long, so you aren’t tied into a lengthy contract, and it’s temporarily just £30 per month (rising to £35 per month from February 2020). VOXI also stands out through offering 5G roaming in the same places as Vodafone.

MVNOs

MVNOs (Mobile Virtual Network Operators) by and large haven’t announced their 5G plans yet, so we wouldn’t expect them to offer 5G SIM Only deals until at least 2020 in most cases.

There are some exceptions though, most notably VOXI, BT Mobile and Sky Mobile. VOXI (which uses Vodafone’s infrastructure) has launched a 5G SIM Only service already, details of which you’ll find above. BT Mobile (which shares coverage with EE) has launched 5G too, but currently only for BT Plus broadband customers.

Sky Mobile (which uses O2’s coverage) meanwhile has announced that it will switch 5G on by November, and it’s almost certainly going to offer 5G SIM Only deals to go with it.

Other MVNOs which might offer 5G SIM Only deals before too long include Plusnet Mobile and Giffgaff, as they’re both owned by proper networks. However, they’re also positioned as cheaper alternatives, so may not be in a hurry to offer a premium service like 5G.

Frequently Asked Questions

What happens if I’m not in a 5G coverage area?

If you’re not in a 5G coverage area then your phone will revert to a 4G, 3G or 2G signal, depending on what coverage is available, just as 4G phones will revert to 3G or 2G when needed.

However, if you don’t live or work in an area that currently has 5G coverage then you might want to wait before getting a 5G SIM deal anyway, since you probably won’t benefit much until you do have coverage.

Will a 5G SIM card work in a 4G phone?

Yes, but of course it will only be able to provide a 4G signal at most. For 5G speeds you’ll need a 5G handset.

What sizes of 5G sim cards are available?

Current 5G networks will provide you with a ‘Multi SIM’, ‘3-in-1 SIM’, or similar, which are different ways of saying a SIM card which can be made to fit any size SIM card slot.

It’s likely that most if not all networks will take the same approach, just as they have done with 4G SIM cards.

However, it’s worth noting that most if not all 5G phones are likely to have a nano SIM slot in any case, as this is the most modern size.

Can I keep my number?

Yes, and the process is the same as it’s ever been.

If you’re upgrading on your current network then your number will stay the same anyway, but if moving network you just need to request your PAC code from your old network (while the number is still active), then activate your new SIM if you haven’t already, and tell your new network your PAC code and old number.

This is usually done via on online form, but the exact process will vary from network to network. If in doubt, give your new network a call.

Can I get an unlimited data 5G SIM deal?

Yes! Currently EE, Vodafone and VOXI all offer unlimited data 5G SIM Only plans. We’d expect Three will continue offering unlimited data when it switches on 5G too.

Why choose a 5G SIM Only deal?

A SIM Only deal typically doesn’t lock you in to a contract for as long as a plan that comes with a phone, and – as you aren’t getting a phone with it – it’s usually also cheaper.

Of course, only a fairly small number of relatively recent phones support 5G at the time of writing, so you will probably need a new phone anyway, but that doesn’t necessarily mean you have to buy it on contract – sometimes it can be cheaper to buy the phone outright and then get a 5G SIM Only deal.
