After dolphin I got Loop sim for its call rates and water kingdom offer. after activation I tried to enter the sim and there was no networks I tried to call customer care after few hours and I was connected to a tech and he suggested me few things still it didn’t work out so later he asked to insert the sim in some other mobiles and I even tried that I changed the sim in 5 different mobiles but no luck and again I called them they asked me to take a new sim. To get a new sim the procedure was really tough and took lot of time.
This was really bad services I have seen from mobile operators.
