It is as good as not using a service than using a Uniconnect Sim card.. we had a terrible experience with using a uniconnect sim for UK. Their idea of a pre paid card is not as useful as i thought it would be. For most of the days, there was perpetually no reception in my phone. I tried whatever their customer support team asked me to, while nothing really helped. Ultimately they stopped taking my calls and i was left with a sim card that just didnt work. It is literally wasting money than convenience. Very bad experience.
