T-Mobile Bumps Up The Data Limit For Their Prepaid "Connect" Plans
tmo.report
The Connect by T-Mobile prepaid plans are getting their final data bucket increases, along with a bit of a bonus on top.

This actually affects me as I use the $15 Connect plan.

Edit: I just checked and my plan has indeed gone from 3.5 gigs of data per month, up to 5 gigs of data per month. That is 500 megabytes of data more than I expected to end up with at the end of 2025.
