The Bold 9900 offers 1200 minutes, unlimited texts and 500 MB of data and a free phone for £42 per month.

Samsung users aren’t left in the cold either. O2 is offering the Samsung Galaxy Ace at £149.99 with the same £20 gift card offer on paygo mobiles.

If contracts are your preference, O2 also offers the Samsung Galaxy Ace for £21.50 per month and 200 minutes, unlimited texts and 500 MB of data – and 250 intra-network minutes thrown into the bargain.

Like the iPhone line? How about a new iPhone 4 S 16 GB for £47 per month which includes the same great package as the BlackBerry 9900.

The HTC Sensation XE is available for £37 per month, including 900 minutes, unlimited texts and 500 MB of data.

And for those who like their unlocked phone and are looking for a SIM-only deal, how does a six-month plan for only £10.50 per month sound? You say you want longer than just six months? Okay. O2 also offers a 12-month, SIM-only, Paygo plan for the same price.
