I have had a really bad experience using Uniconnect Sim Card for London. Not only did they deduct the recharge amount in dollars without any warning on their recharge page, but i had to go through an embarrassing situation of asking someone for their phone to make a call cz my phone stopped mid way!! Mid way in a business call that f****** number stopped. I am totally out of my wits and patience with this cheap company called Uniconnect!!
