AT&T on Thursday announced it will soon roll out discounted multi-line options for families through its prepaid GoPhone brand.

As of August 19 customers will have the ability to add up to five consumer lines per account or 10 business lines per account on GoPhone’s $45 and $60 plans, AT&T said. Monthly discounts will be offered on an increasing scale for each additional line added, starting with a $5 discount for the second line, a $10 savings for the third line, $15 off the fourth line and a $20 discount for the fifth line or above.

The first line of the account is also eligible for a $5 discount via enrollment in AutoPay, AT&T said.

AT&T said the new GoPhone offering has the potential to save consumer customers up to $50 each month and business customers up to $150 each month.

The multi-line roll out comes alongside a buy-one-get-one smartphone offer from the prepaid brand that is running through September 22.

The move will put GoPhone it in a better position to compete with prepaid family offers from the likes of Boost Mobile, MetroPCS and other prepaid carriers and comes as AT&T looks to further strengthen its prepaid offerings.

In the second quarter, AT&T said it pulled in a total of 185,000 branded phone net additions. That figure came despite a loss of 180,000 postpaid phone net additions thanks to the strength of AT&T’s 365,000 prepaid phone net additions in the quarter.
