Using the local sim card that I bought from Uniconnect. After the third day of using that sim, it stopped working saying registration failed. I had to call their customer support centre in India to help resolve this. While in the process of dealing with them, trying to explain the inconvenience that I was facing using their services, the woman on the call outright said that the sim must have crossed its validity days and so now I will have to share my credit card details with them so that she can recharge it and it work. When I told her that Raunak, the guy who sold me the sim card said it’s a fresh sim and still valid to 120 days she said he must have misinformed me as the sim had already expired and then before any warning she disconnected. I had no other option but to stop using their poor services and tell everyone about the same. Uniconnect is the most inconvenient service that I have ever used so far.
