connection all over the place

[Sigrid]

Hey folks So I’ve been messing about with a game on my handheld that’s got an eSIM, thinking it’d just hook up online straight away. Turns out, it’s proper hit and miss depending on where I am. In my flat, it barely connects, but take it outside and it’s mostly fine. Not sure if it’s the eSIM itself or just the network acting up... I actually found mine on mybestsim.com and it's usually decent. Had a fiddle with some settings, but I’m no expert. Anyone else tried this and got it working smoother, or got any tips?
