I used a Uniconnect Sim Card for my trip to US (USA Super Saver Rs. 4,000). Uniconnect Sims was quick to deliver the SIM card but that was the only good thing they could do and I think that was their best service! Call quality throughout the trip was unsatisfactory! Most of the time the sim showed no network! I kept restarting my phone to make it work but of no use! Even complained to their customer service but have not got no help from them. Very dissapointed and do really didn’t see any sense of spending so much money on it and yet wasn’t able to use their services!
