Brilliant

The E-Sim was brilliant it worked perfectly. I had one issue that I eventually solved. My phone picked up the Hotel WiFi but when I left the Hotel my phone did not reconnect to the E-Sim. However I simply switched the Phone Off and On again and the E-Sim was back All good and thank you...
