What is SIM Only?

A SIM Only contract is one which includes a SIM card but no phone. As with a phone contract you’ll be tied in for a number of months (usually one or twelve) and have an allowance of minutes, texts, and data each month.

Why choose a SIM Only contract?

There are a number of reasons to choose a SIM Only deal over a Pay Monthly phone contract. For one thing, they tend to be a lot cheaper, as you’re just paying for your allowances rather than also paying for a phone. This makes them ideal if you’re happy with your current phone or want to buy a new handset outright.

They’re also usually shorter term, as they tend to be 12 months, and in many cases are just 1 month, while phone contracts are almost always 24 months. That means you’re not locked in for as long and are free to change your tariff after a shorter period.

Even if you want to stay with your current network you should definitely switch to SIM Only if you don’t want a new phone, as you could save a lot of money.

Which networks offer SIM Only deals?

All the major UK networks offer SIM Only deals, as do a number of MVNOs (Mobile Virtual Network Operators). We offer deals from the following networks:

Do I have to stick with my current network?

No. Assuming you’re out of contract you’re free to switch to any network. If you’re not sure whether you’re out of contract or not just text ‘INFO’ to 85075  or give your current network a call to check, and while you’re on also ask them if your phone is unlocked, and ask them to unlock it if it isn’t – this is important, as your new SIM card will only work in an unlocked phone or one locked to the same network.

How do I keep my number?

Keeping your number is easy. Once you’ve ordered your new SIM Only deal just text 'PAC' (from your old number) to 65075 or ask your current network for your PAC code, then give it to the network you’re joining. Assuming you do this within 30 days of the PAC code being issued your number will be ported, usually within the next working day.  Find out more.

Will I lose service if switching network?

Yes, assuming you’re porting your number, but only for a very short amount of time while the transfer is actually happening.

Can I switch from a Pay Monthly phone contract to a SIM Only contract?

Yes, the process is essentially the same as moving from one SIM Only contract to another. Assuming you’re out of contract you simply have to order the new SIM Only deal then – assuming you’re also changing network - inform your old network that you’re leaving.

Which network should I choose?

When picking a network there are a number of things to consider beyond price and allowances. Key factors include whether you can tether (use your phone’s internet connection to get other devices online), where you can use your allowances abroad, and what the network’s coverage is like. You’ll find information on all of these things below.

Tethering

At the time of writing, all UK networks allow you to tether on SIM Only, though in FreedomPop’s case you have to pay extra.

Roaming

All UK networks (aside from FreedomPop) now let you use your allowances in the EU at no extra cost. If you want to roam for free beyond Europe your options are more limited, however Three lets Advanced Plan customers roam in 71 destinations, many of which are outside Europe, while customers on EE’s Smart Plans who opt for the ‘Roam Further’ benefit can roam in the US, Canada, Mexico, Australia and New Zealand.

Vodafone customers on ‘Unlimited Max’ plans can also roam beyond Europe, with 81 destinations included in total at the time of writing, while O2 customers on select plans can also roam in many places beyond the EU.

Coverage

4G coverage is now widespread on all UK networks, with them all offering at least 99% UK population coverage, while 2G and 3G coverage is comprehensive. 

Note that many networks now also offer 5G, with coverage growing rapidly. However, networks haven’t yet revealed their 5G population coverage, so your best bet is to use their coverage checkers to check their coverage in your area.

Which networks offer unlimited data SIMs?

At the time of writing, Three, Vodafone, O2, EE, Smarty Mobile, iD Mobile, VOXI, Lycamobile, Giffgaff, Virgin Mobile, Tesco Mobile, and Lebara Mobile all offer SIM Only plans with truly unlimited data to all customers, while BT Halo customers can get it on BT Mobile.

Think about whether you actually need unlimited data or not though, as some other networks still have very high allowances of in some cases up to 100GB.

What SIM card size do I need?

SIM cards come in three sizes. There are standard SIMs, which are usually only used in very old handsets. Then there are Micro SIM cards, which are smaller and are generally used by a number of phones from five or more years ago – so if you have a smartphone but haven’t upgraded in a long time you may need one of these.

Finally, there are Nano SIM cards, these are smaller still and are used by the vast majority of new phones, so this is the one you’re most likely to need.

However, most networks provide a trio, multi or combi SIM, which has all three sizes in one. Then you just tear out the correct size for your phone.

If in doubt you can always Google your handset or check with the manufacturer, and if you ever need a new SIM card size (for example if you change phone) you can just give your network a call and request one.

Will I get a new phone with a SIM Only deal?

No. SIM Only deals only give you a SIM card and a monthly allowance of minutes texts and data – plus whatever other perks your network of choice offers, such as tethering and free roaming.
