During my one month visit to UK. I thought i wud use Uniconnect Sim Card for the entire duration trusting the company’s promise of amazing network coverage. Trust me i did not use that sim card for more than 10 days. Because everytime i made a call, i wud run out of credit and inspite calling Uniconnect’s customer centre for proper details but they weren’t ready to provide an exact answer. I even got the internet plan activated on the phone, but that was also total flop!!! All in all, Uniconnect sim cards is totally waste of money!! Never use them!
