Verizon this week joined the huddle of carriers targeting families with a new promo offer.

Verizon on Thursday launched a deal offering four lines of service with 16 GB of sharable data for $150 per month when users upgrade to the Large Verizon plan or higher. The carrier is also offering a free Samsung Galaxy J3 V smartphone as part of the package.

“All networks are NOT equal,” Verizon said in a statement. “Verizon has now invested about $116 billion in our network since 2000, more than any other wireless company…Now is the time to enjoy the network and switch.”

The deal includes 8 GB of shareable data across four lines, plus 2GB of bonus data – which is also sharable – per line. The bonus data is not eligible for carry over, Verizon said.

The move comes as the dominant U.S. carriers battle it out to win over families seeking connection at a reasonable cost. Among the big four, T-Mobile has been particularly aggressive in pursuing families.

T-Mobile currently offers four lines with 2 GB of 4G data each for $100 per month. The next tier up, which offers 6 GB of 4 G data per line, comes at a cost of $120 per month for four lines. For $160 per month for four lines, T-Mobile customers can get 10 GB per line.

Like Verizon, the Un-carrier is also offering free devices to families. For a limited time, T-Mobile is offering a free Samsung On5 or LG K7 with each 6GB data plan or a free Samsung J7 or LG K10 with each 10GB or higher plan.
