Uniconnect — Very irritating service

I bought a uniconnect sim card from delhi airport and i was informed that this was a pre-activated international sim card and by the time i would land in germany, all i’ll have to do would be to insert the sim card and just start using the same. I had bought their european sim card. Firstly nobody told me while selling the sim that all my calls would be charged in usd which is weird cos i was using a uk number. My free talktime of rs 877 got over the minute i made my first call. The more convenience that i was looking for in a sim card the more horrible my experience was with these guys. No matter what never wil i ever recommend these to anyone.
