Why choose a SIM only contract?

You can have the flexibility of a 30 day contract. This is in contrast to a minimum of a 12 month or up to 24 month plan for standard mobile phone contracts. SIM only deals are great because for instance if you wanted to change to another deal on offer you would only need to give you current provider 30 days notice and you could then move to a better contract deal with no penalties. If you tried to change to a new deal on a standard mobile phone contract halfway through your contract, you would still be liable for the remainder of the fees remaining on the contract.

SIM only contracts offer the most competitively priced tariffs in the mobile phone industry today. The reason for this is that the phone networks only need to provide you with the sim card itself rather than having to supply a phone as well. SIM cards are extremely cheap to manufacture, whereas today’s Smartphone’s cost several hundred pounds the cost of which is often subsidised by the networks to get you to take out a long contract whereby they can recoup the costs through call charges. By taking out the cost of the phone, networks can charge the most competitively priced tariffs. You will be surprised at just what benefits you can get on a £10 SIM only, £15 SIM only or £20 SIM only contract.

By choosing one of our SIM only deals you can keep your current mobile phone. This means that you do not need to learn how to use a new phone, or move all your contacts and pictures onto a new handset because all you need to do with “SIM only” is to plug your new SIM card into your phone. Why should you change your phone if you are happy with the one you currently have?

SIM only deals are offered by all of the major mobile phone networks, EEOrange, Vodafone, O2, T-Mobile, 3 and Virgin Mobile and there are a huge range of different plans on offer at various different price points starting at less than £10 per month up to £35 per month.
