..mmm....well only people with the actual phone can really comment on this but the spec looks good..Samsung ..OK with that..and looking round the reviews it gets good marks there....
I have the SE Xperia X8 and love it...it's my first smartie so nothing to compare it to. It was £69 from Carphone Warehouse... with 3 on PAYG....
With 3 you can top up and use it as a normal PAYG phone that is you spend your credit as you use the thing...or you can buy 30 day add-ons which give you 500gb internet plus texts and calls for 10 quid ..or for 15 pounds you have "all you can eat" internet with loads of the other things......BUT what you don't use in 30 days you lose.........
....sort of like a contract but just monthly.........the amount of downloading I do these are a great deal.........but very flexible ......
....all from me but sure to get other comments...
