SIM-only deals are quite popular among UK residents. With these options, you will receive a SIM card that has the call, texts, and internet data amount you need. SIM-only deals are similar to phone contracts, except for the fact that you will not receive a mobile device. So, why exactly should you consider this option for your contract?

  1. You Don’t Pay for an Unnecessary Phone

If you already have a phone that completely fills your needs, then you don’t need to be paying for an extra one every month. The cost of a mobile phone will be subtracted from your plan since you only need to pay for essential services.

  1.  You Can Change Phones as Frequently as You Wish

If you usually need to change phones after a few months, then a SIM only deal will suit you perfectly. You will only need to retain the SIM card, but your phone can be changed as frequently as you wish. You can make use of services like Compare My Mobile to get the best deal when switching from an old phone to a new one. 

  1. They Have Short Contracts

SIM only contracts usually run on a month-to-month basis, meaning they do not require long term commitment. Usually, you just need to make a one-month notice before cancelling your plan. This makes it easier to avoid lowering your credit score in case you have trouble making your payments. Also, if your needs change in the near future, you will not be stuck with a plan which does not work for you. As you would expect, most providers will not pay so much attention to your credit report when signing you up for SIM only contract deals.

  1. They Are Highly Convenient

A SIM-only deal offers you a set number of minutes, data, and text messages in a month. This means you don’t need to worry about topping up your card every time you need to make a call or send a text. This can add a layer of convenience to the plan. At the same time, if you have a lot of leftover data, texts, and minutes every month, you can always tailor your plan to suit your needs. You will only need to cancel the plan 30 days in advance.

  1. You Still Get to Keep Your Old Number

If you have never used a SIM-only deal, you probably imagine that you will end up having to change your line to a new number. This is far from the truth. In reality, you will only need to contact your current provider to get a Porting Authorisation Code or PAC. You can then contact the new network and give them the PAC, the number you want to keep, and the temporary number provided in the new SIM.


Everyone needs to change their mobile phone plan at some point. You may have been using a phone contract or the pay-as-you-go option, and now you want to move to a more convenient option. The SIM-only deal is ideal for many different reasons. It is cheaper than a phone contract since it does not come with a new phone. It is also more convenient since the plans are shorter. They typically last for a month or a year, and you should be able to cancel them with reasonable notice. Also, you should note that you will still get to keep your old mobile number.
