SIM Only deals and contracts

Not bundled to a handset, SIM only deals are notably cheaper than standard smartphone contracts. They even offer the flexibility to change devices whenever you please. Here at iD Mobile, we offer SIM only deals on 30-day rolling contracts. This means you're free to modify your plan monthly, increasing or decreasing your data to suit your lifestyle.

A SIM or SIM Card is a small piece of plastic that slots into your mobile phone. It identifies who you are to the Mobile Network it connects to, and enables you to connect to the internet, make phone calls and send texts.

A SIM Only deal is precisely that. You purchase a monthly allowance of data for use on the internet, a set number of minutes for phone calls, and an amount of texts to send. The network will send you a SIM Card if you're not yet with them, so you can join their network and use the allowances you've purchased.

SIM Only deals with unlimited texts are now widely available and ones with unlimited minutes are almost as common, but you can still save by limiting your minutes if you don't use your phone to make many phone calls.

Unlike many other networks that tie you into a 12-month contract, at iD Mobile, we sell SIM Only deals on one month rolling contracts. That means that you have the flexibility to change or cancel your plan at any time.

You'll spend much less each month than a standard ‘phone contract' because you won't also be paying for the handset itself. However, you'll need to have a phone to put the SIM in or purchase one that's ‘SIM-free' to put the SIM into. Be careful that your phone isn't locked to a different network from your SIM or you won't be able to use it.

Speedy 4G is offered as standard with every iD Mobile SIM only deal too, and our multi-size SIM cards fit any smartphone to make life that little bit easier.

You'll be able to enjoy the same exclusive benefits all our other iD Mobile customers receive too. It doesn't matter if you choose a SIM only deal, have a regular monthly contract or Pay As You Go, every member of the iD family can look forward to free EU Roaming, Data Rollover and Capping.

With our Data Rollover feature, you'll get a second chance to make the most of your unused data. Whatever's left over from your monthly contract will automatically be carried over to the next month of your SIM only deal, meaning you'll never let a MB go to waste. Capping, meanwhile, ensures you'll never be surprised with a hefty bill. You have the ability to put a limit, from £0, on your out-of-plan spend too - we'll never let you use more than you've agreed.

Finally, EU Roaming lets all iD customers use their monthly data while abroad. Google directions, update Instagram or video call loved ones back home without worrying about the extra cost.

If you already own a phone you're happy with, a SIM Only plan is a wise choice. Not only can you carry on using the device you love, you can look forward to paying less every single month too. As you'll no longer need to factor in the cost of a new handset, your monthly plan will simply include a bundle of minutes, texts and data that suit you.

SIM only contracts are popular thanks to their flexibility too. At iD Mobile, SIM Only deals operate as 30-day rolling contracts, meaning you can modify or end your contract easily by giving us a month's notice. It's great if you find your data usage fluctuates month to month, or if you're not ready to sign up to a new 12 or 24-month contract straight away. Got your eye on a new handset, which won't be released for three months? Try SIM Only while you wait!

On top of all of this, you'll still benefit from network perks like free EU Roaming as a SIM Only customer.

If you run out of an allowance, you can still keep using it (for example, if you run out of texts you can keep sending text messages), but you'll be charged at out-of-bundle rates.

To prevent you from racking up these out-of-bundle charges, it's easy to purchase an add-on of minutes, texts or data (depending on which allowance you've run out of).

Please note: add-ons can't be backdated to cover your past usage. They come into effect when they're purchased, and never before.

Yes. It's simple to keep your old mobile number when you sign up to an iD Mobile SIM Only plan. If you're already with us, you can switch your plan from your account and we'll simply update your monthly allowances and your bill from your next billing cycle. You can move up or down to a lower price SIM Only plan as long as you pass the usual eligibility criteria.

If you're not already with iD Mobile, under new legislation from Ofcom that came into effect on 1st July last year, you don't have to call your old provider to switch. Instead, just text ‘PAC' using your old SIM to 65075. PAC stands for Porting Authorisation Code, and sending us your PAC code will enable us to port (or bring) your old mobile number across to us.

Your old network will send you your PAC code and any information around outstanding penalties, charges or credit due on your account. In addition, if you've completed your minimum contract length with your old provider, they can't charge you for the remainder of your notice period following your switch. So, you won't have to pay two bills at once. Just be careful that you're not still in contract or they could levy a fee against you for leaving early.

You can then simply enter your PAC code here when you've got your new iD Mobile SIM plan and mobile number. We'll move your number to your new SIM Only plan the next working day if we receive it before 5:30pm Monday – Friday.

No. Some networks lock their phones so that they only accept SIM cards from that network. If your old phone was one purchased on contract from a network, it's much more likely to be locked than if you purchased the phone outright from a retailer.

If your phone is locked to a network, you'll need to unlock it. If you're out of contract but bought the phone from the network, you can usually get it unlocked for free. Simply contact the network and ask them to unlock it. (Even if you eventually move on from your old phone, by unlocking it your phone may well be worth more if you plan to sell it or trade it in against the cost of a new handset).

You can check if your phone is currently locked to a network by removing your existing SIM and inserting a SIM from another network in your phone. If it works and you get a mobile phone signal, it means that your phone is unlocked and you're good to go.

Not with iD Mobile. Most other major networks such as EE, Three, Vodafone, and O2 increase the price of their SIM Only deals each year with inflation or RPI (Retail Price Index).

We'll always try to make sure you have the best possible coverage to keep you connected, wherever you are. Use our coverage checker to get an indication of what the signal is like in your area.

Different phones take different kinds of SIM cards. There are three different types: Standard, Micro and Nano SIMs. Usually, the latest devices take Nano SIMs, slightly older ones take Micro and the oldest handsets Standard.

There's no difference in the function of each different SIM card size, so don't worry that you'll be able to do more with one than you would with another if you're moving between SIM card sizes.

Your iD SIM card that we'll send you is 'one size fits all', so you don't have to worry about ordering the correct size. The card you'll receive contains all three SIM types (standard, micro and nano), and you just need to pop out the size you need. You'll normally find the requirement in your phone's user manual if you're unsure about what size of SIM card will fit.

Don't panic if you manage to pop out the wrong size and lose the other parts of your SIM card. You can get SIM card adapters quite cheaply online to help rectify the issue and fit a small SIM card to a larger slot.

Usually, changing your SIM card is a pain-free process that takes under 5 minutes, but it can be fiddly due to their small size. The latest handsets normally arrive with a small ‘pin' device to push into the hole in the edge of your handset to pop out the SIM card tray. Occasionally, these are quite difficult to find but a paper clip or normal pin work just as well. Simply place your SIM on the tray and slide it back into your handset. Your phone's user manual will help you find the hole and let you know which way around you'll need to put your SIM.

It's up to you. Many people find that around 1GB-2GB on their SIM Only deal is fine for them, as you can make use of Wi-Fi coverage when you're out and about, like at coffee shops or hotels. You can also avoid using large amounts of data by pre-downloading any films or music albums you'll want to watch later on your own Wi-Fi.

If you regularly stream music or videos without being on Wi-Fi, you'll need a much greater amount of data. You can find out exactly how much data you'll need on your SIM by checking the network settings on your phone. Most phones will tell you how much data you've used, and you can change the time period on your device to ensure it reflects your regular usage.

If you need a new SIM card, the best thing to do with your old SIM is to treat it like a credit card and cut it up. SIMs can be used to store contacts, text messages and other information that would be worth a small fortune to scammers, so make sure that you dispose of it carefully so you can enjoy your new SIM Only deal worry free.

Yes, but you might find it easier to tether your tablet to your phone. Tethering is a way of turning your smartphone into a mobile internet hotspot - a sort of mini Wi-Fi, so you can get online quickly.

Please be careful as the data you use during tethering will come out of your SIM Only data allowances, and you can use up a lot of data very quickly if you don't take precautions.

The best way to ensure you're not eating up too much of your data allowance is by checking your remaining allowance on the iD Mobile app. At iD Mobile you can also set a Bill Cap so you don't rack up any Out of Plan Charges. Out of Plan Charges have a maximum limit, so you won't pay more than you want to.

If your phone allows tethering, you can usually enable it in ‘settings'.

At iD Mobile, we offer 30-day rolling contracts. If you wish to end your contract with us, we simply need a month's notice. The same goes for editing your contract - if you fancy more minutes or need more data just get in touch!

For Pay Monthly SIM Only plans, we will run a credit check. We'll always ask your permission before this happens, and we'll inform you about our decision as soon as possible.

Due to shorter contract lengths and the absence of a handset, SIM Only applications are more likely to be accepted than Pay Monthly deals. However, if your application has been declined please don't hesitate to get in touch with our team. We'll try our best to find a solution that works for you.
