Information technology thoughts: maybe it is a good idea to travel with at least two phones; an iPhone and an android device, just in case one stops working or the other.
Also, travel with a laptop, even though the additional weight and bulk is annoying.
For example, for some reason or another, my Wi-Fi on my iPhone, and my iPad no longer work. But fortunately, the 4G Sim card I have on my iPhone, paired with Apple iCloud private relay, works.
I agree!
