NEW YORK (TheStreet) -- Verizon (VZ) stepped up its game in the battle for family wireless plans and to get customers to use (and pay) for more data.
Verizon Wireless has updated its "More Everything" plan, its multi-line plan options, for customers who choose Verizon Edge and at least 10GB of data, the company confirmed on Thursday. It cut the cost of smartphone line access to $15 from $40 per month. For plans that use 250 MB to 8 GB of data, customers could receive up to $10 off monthly line access using Verizon Edge. A family with four smartphones using Edge and 10GB worth of data, for instance, would now pay $160 per month for the plan, effectively bringing it more in line with AT&T (T) family offerings.
Verizon has also added "bonus data" for customers who add a tablet to their plan. Adding an eligible tablet for $10 a month, for instance, means customers can get an additional 1GB of data.
Verizon's Edge agreement is its version of offering customers smartphone upgrades without being stuck in traditional two-year contracts. Verizon boasts that customers can receive smartphone upgrades "faster than with any other carrier" through the Edge program, which splits the full retail price of the phone into 24 monthly payments and is added to customers' monthly bills. However, after at least 30 days and with at least 50% of the phone paid off, customers are eligible for an upgrade.
