Nine months ago, we published a SIM Only Comparison Guide that covered 58 offers from eight networks in the UK.
Over that period, the credit crunch only served to make SIM only deals significantly more attractive and it is therefore not surprising to see that the actual number of deals jumped to a whopping 83, a 47 percent increase.
Amongst the mobile phone networks listed are Talktalk (Carphone Warehouse), O2, Tesco, T-Mobile, Orange, Three, Vodafone and Virgin Mobile.
All of them, except Tesco Mobile, have enhanced their offers since last year with the majority of them now offer unlimited texts even on short, one-month contracts.
That said, there have been some sneaky adjustments with O2 and T-Mobile for example offering less minutes on some SIM only deals compared to last year.
The other trend we've noticed is the increase in number of deals offering free inclusive internet with T-Mobile offering one for as little as £10, down from £18 last year.
