how can you guarantee someone will never run out of battery on there phone?? silly comment, when previously travelling to Thailand from the UK, It's 24 hours "door to door" my phone battery was always dead upon arriving in Thailand, so would need to remember to bring a power bank, or charging cable, every time you leave Thailand and return you need to produce your e-visa at the border, I did present my e-visa on my phone once, during a border bounce, and the immigration officer seemed to struggle scanning it, pinching the screen trying to enlarge the QR code to scan it, if in the future you want to extend at your local immigration office, you will a paper copy to complete the extension ๐๐๐น๐ญ๐
