Should you actually get Prepaid Starter for 3 lines?

The editor weighs in — flanked by the optimist on her shoulder and the cynic on the other.
UP
Our takeEditorial
T-Mobile's own prepaid network at $45 with taxes in -- 15 GB, then the speeds fall off a cliff to 128 kbps. Good ceiling if you stay under it.

The Optimist
“$45 with taxes included and no credit check, on T-Mobile's actual towers -- not a reseller.”
— the angel on your shoulder
The Cynic
“15 GB disappears fast, and 128 kbps after is just barely faster than not having data.”
