I’ve used Keepgo’s lifetime world sim for a few years now, and as an international flight attendant, I have found this to be a superb product! Whether going to Asia, Europe, South America, or Oceania, my service has surpassed my friends with t-mobile and google-fi. I have loved the ease of using one phone and swapping between my primary service to this sim, however, the new USA iPhones are no longer being built with a physical SIM card, which means carrying a second device, allowing me to continue to use this exceptional service all around the world. I do hope that they soon create an eSIM option with the same global coverage.
