Here's how Verizon's Share Everything works

With the Verizon Wireless Share Everything plans, subscribers pay for two things -- the pool of wireless data used use every month, and the devices they add to the plan.

Here are the rules:

1. The base cost is a monthly data allowance, shared among all the devices:

1 gigabyte $50

2 gigabytes $60

4 gigabytes $70

6 gigabytes $80

8 gigabytes $90

10 gigabytes $100

2. Verizon allows up to 10 devices on each plan. This is the cost of adding each device:

-- Smartphone $40, with unlimited calling and texting.

-- Non-smartphone $30, with unlimited calling and texting.

-- Laptop, USB data stick or "mobile hot spot" device $20.

-- Tablet $10

Here's  how the Share Everything Plan stacks up against some current plans.

-- One smartphone with unlimited data, texting and 2 gigabytes of data. Current Nationwide single-line plan: $120 per month.  Share Everything: $100 per month

One smartphone with 450 minutes of calling, 1000 text messages and 2 gigabytes of data.  Current single-line plan: $80 per month.  Share Everything: Not available.

-- Two smartphones with unlimited data, texting and 4 gigabytes of data, combined for Share Everything, 2+2 for Family plan.  Current Family SharePlan: $210 per month. Share Everything: $150 per month.

Two smartphones with 700 shared minutes of calling, 1000 text messages per line and 2 gigabytes of data per line: Current Family SharePlan: $150 per month. Share Everything: Not available
