In the USA over 60% of Americans belong to "family plans" plus discounts.
Like my plan including taxes with ATT is $175 a month for 4 phones. 3 lines with unlimited data. Unlimited texting. Any mobile calling and 700 minutes with rollover.
Those who have one line or even 2 lines get ripped off badly with the carriers in the USA.
But family plans often result in big savings especially when many get 15-25% company discounts with their bills.
Mmm... interesting. Here all advantages you get from family plans is saving around 9 per line. Nothing more. I guess that's why everyone tends to have their own line here.
I'll have to find myself a family to stick to if I ever go to live to the US.
