  • Overview

Overview

Why choose a 5G SIM Only contract?

SIM Only contracts are always cheaper than opting for a new handset, since all you have to pay for are your allowances. So if you already have a phone that you’re happy with or have found one to buy outright at a good price, then SIM Only can be ideal.

SIM Only contracts are also typically shorter term than a Pay Monthly plan with a phone. The latter generally lasts 24 months, while SIM Only contracts are typically either just 30 days (for ultimate flexibility) or 12 months. Though in both cases there are exceptions.

That means that usually on SIM Only you’ll be more frequently able to change or cancel your plan if something more fitting comes along.

Note however that to make full use of a 5G SIM Only contract you will need a 5G phone, so if you don’t already have one then you’ll need to buy one separately. You can use an existing 4G phone, but you won’t get 5G speeds.

Which networks offer 5G SIM Only deals?

At the time of writing the following networks all either offer 5G SIM Only deals or likely will do soon.

EE SIM Only

Vodafone SIM Only

O2 SIM Only

Tesco Mobile SIM Only

Three SIM Only

VOXI SIM Only

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.

EE’s 5G SIM Only plans come with ‘Swappable Benefits’ letting you choose between extras that you can swap out whenever you want.

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.

Tesco Mobile

Tesco Mobile, who use O2's network, offers a range of 5G SIM Only plans on 12 month contracts and 30-day no contract plans.

12 month plans start at £15 a month and come with unlimited minutes and texts. The maximum 5G data allowance is currently 100GB, so there is no unlimited data plan at the current time.

The 30-day no contract plans costs £5 a month more than the 12 month plans.

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.

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.

Which networks offer unlimited data on 5G SIM Only?

At the time of writing, EE, Vodafone and VOXI offer unlimited data 5G SIM Only plans, while Three offers a 5G-ready SIM Only plan with unlimited data, meaning 5G will be supported by it once the network launches its 5G mobile service.

Which networks have the best 5G coverage?

5G coverage is rapidly expanding on networks that already offer it, while many networks that don’t are likely to launch soon. As such, the best way to stay up to date is to head to our in-depth 5G coverage pages.

What else should I consider when choosing a 5G SIM Only contract?

Beyond allowances, prices and coverage, there are plenty of other things to consider when choosing a network for 5G SIM Only, as they all offer different things.

One obvious point of comparison is free roaming availability, as while they all let you roam for free across most of Europe, some networks also let you roam further, and Vodafone and VOXI even let you roam at 5G speeds in a number of places.

Tethering is another thing you might want to consider if you plan to use your phone to get other devices online, like you would with a 5G broadband device, though most networks now allow this with few to no restrictions beyond your data allowance.

There are then things that are unique to specific networks. For example, some of Vodafone’s plans come with a subscription to an entertainment service of your choice, while many EE SIM Only plans come with Swappable Benefits, giving you the ability to change your perks every month. Three and O2 both offer apps (called Wuntu and Priority respectively) full of competitions, freebies and discounts, and BT Mobile gives customers free access to its UK network of around 5 million Wi-Fi hotspots.

What SIM card size do I need?

No matter what network you choose, you should receive a customisable SIM card that can be made to fit a SIM card slot of any size. These are variously called a Multi SIM, Combi SIM, Trio SIM, and other things, but they’re all the same idea, so you don’t need to worry about requesting a specific size or using an adaptor.

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.

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 a SIM card for my tablet or mobile broadband dongle?

Yes, but you will a data only SIM which only come with a bundle of data and don't have included minutes and texts.
