Is SIM Only right for you?

SIMO deals are right for you if…

  • You are happy with your current phone
  • You are looking for a mid range phone
  • You need to use a specialist MVNO who doesn’t sell  phones
  • You would like to try a new phone that the networks don’t stock yet

Will a new SIM fit in my phone?

It’s an important question – there is no point finding the ideal new contract if it won’t work in your chosen device. The short answer is don’t  worryA lot of mobile phones are supplied unlocked, and if your phone came is part of a contract then the network is obliged to help you unlock it for free or a nominal fee.

Even if your phone is locked it is usually quite easy to unlock it.  For a more detailed explanation check out our unlocking guide.

Keep your phone and pay less for the texts, minutes and data you need. That just about sums up the SIM only proposition for must people, but it is only the start. There are a range of specialist MVNOs who offer unique features or extra flexibility that you just can’t find from a major network.

Mobile phone contracts are often confusing  and come in a range of prices and flavours. The whole point of this site is to save you time and money by collecting all the SIMO deals on the market into one place.
