Best SIM Only Deals for July 2018: Free Netflix with O2 SIM only contracts

Best SIM Only Deals: So perhaps you’ve bagged yourself a shiny new SIM free smartphone, but now you’re on the hunt for a great value SIM only deal. Well, you’ve come to the right place.

Picking up a shiny new mobile phone can be rather expensive once you’ve added together all of the sums. Most contracts will tie you into a 24 month contract, locking you into the same provider. Who knows what your circumstances will be in the next 24 months.

A SIM only deal might therefore be your best option, giving you the flexibility to change provider or tariff on the fly. It’s also potentially a much cheaper way to get the phone of your dreams. If you can afford to buy a phone outright, it’ll work out much cheaper to then get a SIM only deal. The total cost of ownership after 24 months will be much lower than a contract.

It’s also worth looking at a SIM only deal if you’ve come to the end of your contract. This is because your contract’s monthly cost includes both your phone service as well as a contribution to pay off the cost of your phone. Once the phone is paid off at the end of your contract, there’s no need to pay as much, so it’s worth shopping around for a new SIM only contract.

While the ultimate SIM only deals with unlimited data remain an elusive beast, many of the options we’ve listed below have a generous amount while also giving unlimited calls and texts.

So without further ado, we’ve done the leg work and rounded up the UK operator’s best SIM only deals for you below.

How to choose a new SIM only deal

Keep your old phone number

If you do take out a new SIM only deal, there’s no reason you can’t keep your old phone number. Just ask your old provider for a PAC code, then give this to your new operator. This code essentially gives them permission to port your old phone number across to your new operator. No need to message everyone in your phone book with your new digits and just think of all the money you’d save from not having to print any new business cards.

Check the network coverage

Everyone’s network coverage experience is going to be different because it’s all dependent on location and distance from the nearest cellular tower. As such, it’s important you check the network coverage for both voice and 4G wherever you plan on using your phone most. Typically, it’s a good idea to check your home and work address. A high data sim might be tempting but if a particular network doesn’t cover your intended destination, then those dreams of watching Netflix atop a mountain could fly out the window.

Simply pop your postcode into each network’s coverage checker to get an idea of what you can expect:

Wi-Fi calling

All of the UK’s big operators (that’s O2, Vodafone, EE and Three) support something called Wi-Fi calling now. This lets you use a Wi-Fi connection to make and receive calls and texts, bypassing any network coverage woes. This function is dependent on your phone being compatible with Wi-Fi Calling and you turning on the necessary settings.

Unfortunately, EE doesn’t provide Wi-Fi Calling for SIM only contracts, only on phones bought as part of a pay monthly contract.
