Early on this year, got shipped to a different dept in my office where I was supposed to move in States and Mexico every now and then. Though, my office provided me a roaming sim card, that was an absolute crap service. I was not sure exactly which network I chose. So, glanced over some online reviews and compared their tariffs and, finally, decided upon Worldsim. At last, got assurance on my oversea communication with a truly promising brand.
