Free O2 SIMs

Free O2 Sim Cards »

O2 are currently offering the chance to get up to four free O2 sim cards with unlimited O2 to O2 calls and texts as long as you top up at just £15 per month.  This lets you take advantage of O2 network rates and benefits while still making use of your existing phone.


If instead you choose a monthly tariff, with options at a variety of different prices, you will generally receive:

  • A free mobile phone
  • Free call time
  • Free text messaging

You should be careful not to choose a phone deal just because of the initial offers, because you may find you have signed up for a monthly tariff that does not fit your circumstances and end up paying over the odds for call time. Check a range of deals, both pay as you go and monthly tariffs, before deciding on the one you want to go for.
