Just looked at the site. Pity about you having to use up your credit within 90 days. Not sure which card you are using, some have surcharges?
Useful if you are on the phone a lot & you can get £5 cards. However at the moment I can't forsee us doing this much calling.
Great for those with family & friends over there who are missing them or for those with Turkish sweethearts - I remember my outrageous phone bills before I found one-tel did 3p/minute calls to USA.
