Decimal ISP is the ISP used by everyone in MC-OS, with no alternatives (to make things simpler). It currently has no logo.
Decimal ISP provides internet access to everyone, which means it's the go to place if your stuck with internet problems. It also has 2 hotlines with one being an actual discordtel number. There is no yearly plan, unfortunately.
It's plans are as follows:
How to use
To upgrade, simply say in either the world location (When at the location in character) or on the website "upgrade [Plan]", [Plan] being the plan you want.
To contact support without dtel, simply just say "call".
