Man, the Netherlands sound pretty pleasant, overall.

Humidity plays a big part of that I think. Like, don’t older folks start dropping in England around 85-90f because of the humidity there? In Phoenix 107 sucks hard, but it’s dry so you can still effectively cool off.

Just fyi, I believe T-Mobile is one of the main networks that Fi uses. So it’s still possibly network related.

Algorithms don’t have “inspiration”.

I’m not sure what country you’re in, but have you tried Amazon? I found Verbatim 50 packs of 25GB for $40 and Ridata (usually good quality discs) for $28. If you want small amounts there’s various 5 packs for less than $10.
