As a young tech trying to get started, Knoppix live CD enabled me to clean viruses and recover data for clients.
After years of using it as a specific tool, I decided to daily drive it when an older machine stopped accepting Windows Updates.
I still run Windows on my big rig, but Debian on everything Else.
MetroPCS in southern US has same “issues”, running on T-Mobile. 🤦♂️ I’ve bounced between the two services enough times to understand the difference.
Spring Break here… Only T-Mobile customers get usable and consistent data.
