Why choose a SIM Only deal?

If your mobile contract has ended and includes a consideration for the purchase of a mobile phone then you could save a great deal of money as the monthly payment can be substantially reduced. It is for this reason why you should choose a SIM Only deal when your mobile phone contract ends and you wish to keep your existing mobile phone.

Top reasons for choosing a SIM Only deal

SIM Only deals are available on short contracts that can last as little as a single month, short term SIM Only contracts allow you to try out different networks before deciding on a longer term deal for the mobile network with the best coverage for where you live, work, or travel. Longer term SIM Only deals can potentially save you even more money as longer term SIM Only deals are sometimes offered with more inclusive data, minutes, and texts than mobile phone contracts that include a combination of a device and network services.

Other reasons why people choose SIM Only deals is because they have purchased a phone directly from a retail store and prefer not to have that device tied to a specific network. Often the resale of a mobile phone will be more appealing to buyers if the mobile phone is not tied to a specific network.

What is the best SIM Only deal?

Once you make a decision to go SIM Only the next key thing to consider is the network and the amount of inclusive data you will require. From here you can then understand the best SIM Only deal for you, balancing cost, mobile data, and the contract term.
