I was using Uniconnect’s international sim for US. And that was my only mistake. I was having trouibles with their services as everytime I would connect to the wi-fi and then log out, I would perpetually lose network. Inititally I thought it was my handset problem, but when I tried it on my sisters phone also it was the same. So I finally decided to call on their customer cre no @ ********00 and tried and tried and forever tried to connect but nothing happened. Infact I even dropped a message to the guy who got me the sim but even he didn’t care to respond. Seriously using their service is like punishing urself for trying to stay connected.
