Decided to use a matrix international sim card after several poor experiences with Clay or infact my very own indian number. Constant issues with bills and network with these networks. Using Matrix Sim was my last resort. I had no expectations honestly, maybe that’s why I was surprised. Liked their sales guys, who were upfront with explaining benefits of using the European sim card than carrying 2 different sims. Finally bought their prepaid sim card, more so since I was experimenting so didn’t want to get into the hassle of credit card and all. Excellent choice, I would say! Amazing and affordable deals. Defintely better than my last few experiences with others.
