I came up with the best travel trick ever. I changed my phone name to match my home WiFi network and made the password the same as the home network.
My kindle,and all my other WiFi devices like blood pressure monitor, heart, cpap, scale, Nintendo switch, hair curler, toe nail trimmer, and gold fish tank, were able to connect to the internet just like home. Seamlessly!
iPhone -> Settings -> General -> About -> Name
iPhone -> Settings -> Personal Hotspot -> WiFi -> Password
Bonus! Most important! Turn it off when you get home or all your data with go away!
But wait what do you call your iPhone when you aren’t traveling? My regular phone name is the same as my webpage. No reason.
