Everyone's case is different, but in my case NEXT is going to save me some good money.
Previous plan:
Family Talk 1400 -- 1400 monthly minutes with rollover, unlimited text, unlimited mesasges, unlimited data on two lines.
Line 1:
Family Take 1400 - $80
Family messaging unlimted: $30
Unlimted Data: $30
Line 2: $10 (9.99, rounding up to make the math clean)
Unlimited data: $30
*** OLD PLAN TOTAL Line 1/2: $180/month.
We use a ton of minutes (can't remember the last time I used land line), and average about 3.5-4 gigs of data a month. Our peak data usage over the last 12 months was 6.9gig. Lowest just under 3.
My son is now old enough for a phone, so I got him a 5s as we switched the to the new plan.
Current plan: 10GB Mobile Share
$100 base rate for plan
$15 x 3 for three lines = $45
$22/month
TOTAL $167/month.
I save $13 a month (not a ton) BUT I got a new phone out of it. Had we not added the additional line, the total would have been $130/month ($100 base + $15 x 2lines). That is a savings of $600 a year.
We also plan to add two new phones (6/6s) on the Next plan. The month payment on those will be about $33/44 each... but we will also sell two old 5s on eBay for a combined $650ish.
So for our situation - Next was a positive. We would have to nearly double our data usage to get to our limit, and for $30 more/month I can switch to 30g a month, which I cannot imagine hitting.
