Linhoff Teknikaa I have been a Google Fi customer for several years. They recently cut off my data in Thailand because the user agreement states you must spend most of your time in the US.
I moved to Thailand from San Diego. I am trying to maintain a few things like a US bank account and my longtime phone number for a lot of reasons. I transferred my phone number to Google Voice and got a new phone number on Google Fi. The new number is practically unused. I got a 2nd sim card and phone plan from AIS. It seems to work out well. The Google Fi account is currently paused. I un-pause it when visiting the US.
