A SIM only deal is similar to a standard mobile phone contract, except instead of getting a new handset with your purchase, you simply get the SIM card.
By not having the cost of a handset to pay back through your monthly line rental, SIM only deals are generally much cheaper than mobile contracts. Heavy data users can enjoy large monthly allowances at lower monthly costs, alongside shorter contracts.
People in the UK can now benefit from using their existing network allowances at no extra charge when travelling within the EU. Usage beyond the EU e.g. American and Australia will depend on your particular SIM only plan and network provider.
Combine your SIM-only purchase with a SIM-free phone to save money in the long-run. Buying a phone outright and pairing it with a SIM-only deal can often work out cheaper over a two year period. Find out more with our blog on The benefits of choosing a SIM-free phone.
This means using your mobile phone as a hotspot, allowing other devices to access the internet via your data allowance. Most networks (except currently iD mobile) allow tethering on contract and SIM, but just be aware that it will turn through your monthly data much quicker.
If you want to change network, but keep the same number, just contact your existing network provider and request your 'PAC' code. Remember, there may be an early termination fee if you’re still in contract. Your PAC code will be valid for a specific time period (usually 30 days). Then, simply call your new provider and give them the PAC code.
Different handsets can require different SIM card sizes, however all of the SIM cards available at Mobiles.co.uk are combination SIMs (sometimes called multi-SIMs). These SIMs are perforated plastic, and can be snapped down to the required size. For more information, see our blog on What size SIM does my phone need?
If you want to change networks, just check to make sure your current handset isn’t network locked. The easiest way to tell if your phone is unlocked is by testing with a SIM card from another network provider. First, turn your phone off, then remove your existing SIM card and swap it with one the same size from another network.
This one is entirely up to you. Take a look at the different benefits offered by each network, and check the coverage in your area.
Our deals change regularly, and can depends on the type of contract, length, data, minutes, text allowance, and any particular promotions currently running.
A rolling SIM only deal doesn't have a specific end date, and rolls monthly, eliminating any contractual commitment. You can cancel at any time by providing your network provider with a 30 days’ notice.
No - Sim only is as the name suggests, and doesn’t come with a handset.
Yes, you’ll just need to contact your current network and provide 30 days’ notice to cancel your current contract. If you’re still in contract, you may incur an early termination fee. If you’re happy with your existing provider you also have the option to upgrade to SIM only if you prefer.
The best way is to contact your network provider, although handsets can be unlocked via an independent high-street phone shop. Just remember that unlocking your phone through independent means may invalidate the warranty.
Choose from a 30-day rolling contract, which will let you change your package from month to month - or get a 12-month deal and enjoy even more minutes and data for your money.
It's still possible for you to transfer your number by requesting the PAC code but be aware that any unspent credit on your existing SIM card won't be transferred.
Yes. All pay monthly deals require a credit check, however you can be passed for a SIM only deal with a much lower credit score than you’d need for a handset contract.
Even after you've given the PAC code from your old outgoing network you'll still be able to receive data, texts and calls. When the old contract deactivates, the new one will activate with your number.
Yes, cashback deals are available on SIM only deals as both new contracts and upgrades.
A data cap is a feature offered by a number of networks that allows you to set limits on the amount of data you use per month. Many mobile phones also come with a data capping option built in which you should be able to find in the settings options on your device if available.
If you have transferred all of the information saved on your SIM card that you want to keep, like contact numbers, messages or media such as photos, the best option is to cut your SIM card with scissors making sure to damage the metal chip. This makes the card unreadable and safe to dispose of.
If you have a tablet that accepts a SIM card, you could use a SIM only deal to access data. Many networks also have specific policies about using SIM cards in other types of devices. Unless you have a tablet with a calling function you'll also lose out on using the minutes as part of the deal and won't be able to use the texts regardless.
Ever thought about getting a SIM-free phone or SIM-only contract? These are the benefits.
The SIM card is the heart of your smartphone. Without it you would not be able to make calls, send texts or connect to a data service to browse the web and send emails.
