I came across Uniconnect Sim Cards on the airport, when their sales guys literally stalked me through the passage and some how convinced me to buy their pre paid sim card for UAE. I should have presumed how pathetic their services would be.. I made 2-3 calls and all the credit blew away, where I don’t know. On continuous calls to their customer centre, they just said that its pre-paid madam, we don’t keep records. Well I fell for a bad service, just warning you all from the same.
