On arrival to Japan
On arrival to Japan, I received a notification to connect my sim, I made sure the sim was downloaded and showing on my phone before I left the Uk as previous experience with esims can be stressful if you arrive at your destination only to find out you cannot work out how to activate your travel sim. It is amazing to have the convenience of access to data and what’s app calls and google maps. So thank you Ubigi sim
