On a friends recommendation, I bought a Uniconnect international sim card and totally regeretted it immediately after I started using it. It mite have been good for her, but for the European sim card I bought, it was a total disaster. The sim didn’t work despite having 4000/- loaded as credit on it. It showed all signals, but could barely connect to any call. I had to use a payphone to call their support team and even they didn’t offer any respite. Totally poor experience. Should have stuck to using my indian number.
