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.
