Never trust Uniconnect sims for anything. I was using their sim card for only purpose of it being a prepaid service. Thinking using prepaid would be better than carrying a postpaid number, but I was wrong. Their service in Australia was so so so bad. There were no signals and recharging their number is a really expensive deal. For such a pathetic service provider, I still landed up spending 10K on it. Total waste of my money. Never using it again.
