Uniconnect sim cards claim to be the cheapest for their US deals. Honestly that is not the case. Sharing my experience here: I definitely was looking for a cheaper sim card for States, bought their international sim card and regreted it later. On face value its cheap, but in reality its really expensive. Firstly I spent 4199 to buy myself a data extensive plan (10GB to be in particular). Have to say great pre sales services! But the moment I landed in Boston and started using the sim card, I faced reality. Allways unavailable network. That so called 10GB data never worked. I mostly had to use the wifi. Calling the customer care to complain on all these, was such a waste of time and energy. No help from their end either. Its best to steer away from all such services.
