Buyers can grab a two-year deal, with 500MB of 4G data for £31 a month, with a free handset, while the 8GB allowance will set folks back an wallet-emptying £56 a month.
Big boys on board
The Android 4.1 Jelly Bean device, which also boasts Sony's Battery Stamina app and 8GB of onboard storage is available for £25 a month with Vodafone (300mins 250MB, unlimited texts, free phone).
However, the £28.50 a month tariff on Orange seems a better deal with 1GB data, 600 mins, unlimited texts and a free phone.
O2 and Three mobile had previously indicated that they will be selling the device, while the SIM-free price on Expansys is listed as £339.
In a recent hands-on review, TechRadar's Gareth Beavis summed up his early verdict by saying: "With this spec list wouldn't look too out of place on a new flagship phone from another firm right now – and with a lower price, that's an ace notion."
If you're struggling to scrape the pennies together for a flagship handset like the Xperia Z then you could do a lot worse than the Xperia SP. Check back in the coming weeks for the full, detailed review.
