Never ever use Uniconnect for international calling purposes! I had taken one on a recent business trip to US prepaid card, which I thought would be economical. Turns out the plan was bogus and a scam and these cheats took the money but the card never worked! The card did not work most of the trip and after repeated calls and waste of my time when it worked I ended up paying a bombas talktime would get over within 10 minutes of call! Really pathetic and horrible experience!
