I am thinking about setting up Graphene but wanted to make sure I fully understand any drawbacks or limitations. I found this webpage which seems a great resource, but I'm new to this world and not sure that I understand it all. Does no Google Pay mean I couldn't use Google Wallet/my credit card, train tickets, etc from my phone? Also, I have Google Fi as my carrier (I liked their international plan); does that change anything? Would it be prudent to switch carriers? TIA 😘
