You may be able to get better value on texts from another operator (e.g. €0.09 for all texts with [broken link removed] pay as you go as far as I know).
I presume you know that you get 300 "free" webtexts a month if you register on their website regardless of what package you're on as far as I know in case that's of any use? Some or all tariffs (definitely pay as you go) allow you to register up to three Friends For Less for cheaper than normal calls/texts.
