So you move around a lot between 2 locations. Is it possible to set up two completely isolated systems (e.g. bank accounts, online accounts & devices), including a cheap second phone. The only interface between your two isolated systems would be the proven international money transfer services? Global money transfer between individuals (or yourself) I believe is the focus of all these remittance services of which I see all these ads lately. Of course they will charge a fee. I believe your use case is super common and many services target this use case. TLDR: Global money transfer is probably not something you can do casually and frequently. There are specific services, and fees, and headaches. Probably you want to minimize the amount of individual transactions as much as possible to minimize the headaches (of course there are cashflow limitations).
