India, April 15 -- Comcast has adjusted pricing on unlimited 5G plans in a way that shrinks the monthly fee as Xfinity Mobile customers tack on additional lines.

Comcast's previous 5G unlimited plan sold for $45 per month per line. Under the new model, the baseline price for one line stays at $45 per month but begins to drop as lines are added, down to $30 per month when customers take four lines.

While one 5G unlimited line for Xfinity Mobile still costs $45 per month, the combined price moves to $80 for two unlimited lines, $100 for three unlimited lines and $120 for four unlimited lines. Comcast confirmed that the price drops to $20 per line for additional unlimited lines that are taken beyond the first four.
