What is a SIM Only deal?
A SIM Only deal is a mobile tariff offer of minutes, text and data (or any combination) that does not include a mobile phone. Therefore you would need to have a mobile phone already to be able to take advantage of one these offers. If you ordered a SIM Only deal you would expect to receive a SIM card only and nothing else.
SIM Only deals: are they worth it?
SIM only deals tend to be contracted for a shorter period that a pay monthly mobile plan, which allows you to be more flexible about your choice of phone. You may continue to use an older, perfectly serviceable handset or purchase one in a different way. Currently you could choose to by a mobile phone on finance and pay it off monthly, separately from the SIM Only contract, trade in an old handset or indeed buy a second hand handset. SIM Only deals tend to attract two distinct types of customers, customers who are looking for value and customer who tend to change their handsets more often.
SIM only deals: are they cheaper than phone contracts?
SIM Only deals either have larger allowances of minutes text and data, or they are significantly cheaper than normal contracts. The networks are able to do this because in a normal 24 month contract deal, a portion of the monthly line rental is to cover subsidising the mobile phone, to make it more attractive when you connect. They also tend to be for a shorter periods of time, you can get SIM only deals on 30 day rolling contracts as well as for 12 months. Once you are out of your minimum contract time you would normally have to give 30 days notice.
How much data will I need?
Good question, how much do you use your phone to access the internet, social media, listen to music, watch you tube, Netflix or other video streaming services? Don’t know? If you are leaving a network to get a great SIM only deal you can ask for your last 3 months average data use. If you are completely new to mobile then it would be good to know that the average user, uses 2.5gb of data per month. Most networks will allow you to move up a tariff so if you find in the 1st month you have used more than your data allowance then move up, pay more per month and get some more data.
More SIM Only FAQs
You may see different variations of the SIM Only contracts displayed, no contract, 30 day contract and 12 month contract. We feel the no contract versions are slightly misleading as more often than not there is a 30 day notice period, therefore whether it is no contract or 30 day contract in both cases you would have to give notice the day you connected to only get 30 days of service. 12 months SIM only contracts generally have greater allowances or are cheaper per month because you have agreed to a minimum of 12 months.
Whether you are in or out of contract you would need to contact your network customer services for a porting authorisation code ( PAC). If you are out of contract this will trigger the 30 days notice period, you will no doubt have to give your current network, you will get the code and then a final bill. If you are in contract and you ask for a PAC code there may be charges to end the contract early, if you happen to ask for a PAC code at more or less exactly 30 days from your contract end then you will get the code and a final bill.

The SIM is short for subscriber identity module, great answer for a pub quiz! Good news is that the SIM over time has got smaller and smaller. Back in the day they were the size of a credit card and now most phones are either a micro sim or a nana sim. The good news is the networks know this and will provide a sim card that will have a push out to fit the phone of your choice. If you need to go back up to a micro from a nano I would suggest contacting your network for a replacement sim to ensure that you have one that fits correctly.
If you have more time take a look at our article, ‘What is the best mobile phone network?‘ which cover this in great detail, but the short version is that Mobile Networks (MNO) have great deals if you go direct but they tend to be a bit less flexible than the smaller Virtual Mobile networks (MVNO). If you want to know more about the differences between networks, take a look at our article, ‘What is the difference between a Mobile and a Virtual Mobile Phone Network?’. What do we mean by saying less flexible? They tend to have 30 day rolling and 12 month contracts that have a lot of perks, EE give you 6 months of free Apple Music with certain deals which alone is worth £60.00. O2 SIM Only deals allow you take advantage of O2 priority. MVNO’s tend to offer simpler propositions which concentrate on value.

If we concentrate on the coverage for the MNO this will cover the MVNO’s as well, if you take a look at our article what is the difference between a Mobile and a Virtual Mobile Phone Network? There is a non-exhaustive list of what MVNO’s use what network. When you are connecting you should be able to do a coverage check during the application process. If you do buy a SIM only deal and you do have coverage issues all online sales are covered by distance selling regulations so you will be able to return and cancel.
If you have a handset that was initially supplied by a network directly it is likely that the handset will be locked to the network. Therefor it would be necessary to unlock the handset before using it with a SIM only deal with another provider. See the guides below to help you to do this.
All devices sold by EE are locked to EE. This means they’ll only work with an EE SIM card – they won’t work with another network’s SIM card (apart from Virgin Mobile). Depending on your device, it’ll unlock automatically or you’ll need a code from the original network to unlock it. You can call EE using 150 from your handset or call 0800 079 8586
- Any iPhone or iPad sold directly by EE, on or after 1 September 2015, will be unlocked automatically once it reaches 18 months old.*
- Google Pixel phones (all variants) automatically unlock themselves on day 721 from point of activation. You’ll receive a device configuration notification to confirm when it is unlocked.
- All other devices require a code to unlock them for use with other networks. Please contact the original network to obtain a code.
*replacement devices will be unlocked 18 months from the point they are first used
This applies to pay monthly, pay as you go and small business devices – not corporate devices. Devices connected to corporate accounts are not eligible for unlock. To raise an unlocking request for a corporate device, contact your Account Manager.
EE aim to unlock all devices within 72 hours. If they need to contact the manufacturer to get a code, it may take 10 days. But they’ll be in touch if that’s the case.
If you’re on an O2 Pay Monthly tariff, you can unlock your phone or tablet at any time, for free.
This doesn’t affect your contract – you’ll still need to see out the rest of it, depending on your device and tariff.
If you’ve got an iPhone or an iPad, you’ll need to connect it to iTunes once you’ve put a non-O2 sim into the device. iTunes will then tell you the phone or tablet is unlocked.
For all other phones and tablets, you’ll get a text with an unlocking code. Simply enter this into your device and follow the instructions.
The Network Unlock Code or NUC (sometimes called a Network Unlock PIN or NUP, or Network Control Key or NCK) allows you to unlock a mobile phone from its original network. You can call Vodafone using 191 from your Vodafone handset or call 03333 040 191
It’s free for consumer and small business customers to request a NUC.
To get your unlock code, Vodafone will need some information from you first. Once they’ve received this information, they will contact you within 48 hours. Sometimes they may need to get in touch with your phone’s manufacturer, which can take up to 10 working days.
Please note: If you’re no longer a Vodafone customer, you can still request your NUC from Vodafone as long as you previously used your phone on their network.
If you have purchased directly from Three and this is after 1st January 2014 your handset will already be unlocked.
Handsets that are used to access Virgin Mobile’s services are locked to the Network. If you wish to unlock your handset from the Network you will need to contact the Virgin Team on 0800 052 0800 and pay the Charges for unlocking your handset as set out in the Tariff Table. You will also need to have paid all Charges owing on your account before they unlock your handset. For security reasons you will also need to register the handset you wish to unlock with them before they unlock it for you.
