I've had a pretty rocky relationship with telco 3 Ireland over the past couple of years. Their customer service is appalling so even getting the simplest things done can be a nightmare but their data packages are second to none in terms of value and their 3 like home 'promotion' is unrivaled in the current Irish market.
Yesterday, I discovered that they are now offering 333 free webtexts per month to their 3 pay, pay monthly and best of both customers. The service seems limited to national numbers only, probably reflecting 3's lack of roaming agreements with foreign telcos but still, particularly for those of us who spend a significant chunk of our day in front of a PC, this is great news.
