I'm on an Orange plan where if i put £10 a month on my phone i get 300 texts, 600 orange to orange mins after 7pm and 1mb wap, but it was special at the time one Christmas they might do it again though or you could ring and say you were recommended it and can you have it, blag blag lol.
They still do it without the minutes though, you get 300 texts and the 1mb of wap but no minutes, if you put more on you get more texts
