Did that several times using cheap eSIMs while traveling.
Never had a single problem with it (but increased latency because of weird routings around the world).
I have an "always on" VPN routing back home. Anything destined for my home network gets routed that way, and there's literally zero battery drain.
I'm not paranoid enough to route everything through VPN though.
I already use SDNS with Nextguard, and all traffic is https encrypted, and my day to day business on the internet is probably rather boring to the majority of people. Not saying I have nothing to hide, everybody does, but my visits to various news outlets, social media and other sites is probably not all that interesting.
The most interesting data about you comes from your phones constant reporting of cell towers, which can be used to triangulate you, and put a timestamp on where you were, when.
UDP (which WireGuard uses to encapsulate your data) traffic is often de-prioritized. You won't notice it when the network load is low, but it will seriously degrade experience during high load periods.

Not sure if dang see this, but it might be worth asking hn@ycombinator.com otherwise
Maybe a flood protection for new accounts.
Maybe someone knows better alternatives?
