The only choice you have is if you have are a permanent resident with an Alien Certification or ACR-I
Or you register it to someone you know and trust.
Or you live in one of the supported countries: https://help.gcash.com/hc/en-us/articles/900005342766-Use-GCash-Overseas
I’m dual citizen and have a Philippine ID and permanent local address so no need for those. GCash overseas is very limited compared to local GCash. Besides, it doesn’t solve the problem of Philippine banks requiring a local number for OTP.
The problem with the Globe Travele eSIM is it expires automatically after 30 days. No way to extend it. Only option is to buy a new eSIM (with new number).
