We first got conned into buying one of these Sim cards with 6GB data and calling in San Francisco. It allowed me to make one international phone call an use 1.5GB of data. It was very sparatic when it worked, then it just didn't anymore. No data or calling after 2 days even though it only allowed us to use quarter of the data. Then stupidly got sucked into buy another Sim in Portugal cause we couldn't top up the USA one. Again it said 5GB but this time didn't even allow us to use one. Stupidly we then topped that up €10 that lasted literally 5 minutes. We then again, she we are very stupid, purchased a 3rd Sim for €15 which was meant to have 20GB. AGAIN it didn't even allow us to use 2GB and it stopped working. Wish we had checked the reviews. This company is an absolute scam. It has cost us easily $200usd for feek all. Do not purchase anything from them EVER! They are thriving criminals.
