Uniconnect Sims are the worst option available for any pre-paid service in international sims. I had booked myself an international sim card through their website for Germany and after a tedious process of adding everything in the cart and paying some hefty amount of 4200 rs for voice and data plan plus the cost of the sim card, I was really expecting their services to be good. But when I actually started using the sim in Germany, it was a total let down. Their voice transmission quality was really poor, I could barely understand what my wife was saying on the other end. And I have to say that its not even close to being an affordable prepaid service. I exhausted my entire credit of 4000rs in 3 days which is a lot of money and surprisingly these only local calls. I realized only after spending another 2 grand on recharge that this service is not worth it at all. Terrible
