"At Sprint, we're always working to make your wireless experience as simple as possible. Starting with your February invoice, your monthly charges will be presented differently. From now on, we'll separate the primary line from the second line for all Family and Business Share plans. We hope this is a helpful change that makes your monthly bill even easier to understand.

And don't worry – your invoice amount is not changing, and you'll continue to receive the great Sprint service you've come to love. In fact, Sprint remains the value leader for individual and share plans and is the only national carrier to offer truly Unlimited data for all phones with no overages, data caps or throttling. All while on the Sprint network."

Right...your invoice amount is not changing, BUT, the amount you need to remit is changing. The service discount (e.g., 23%) used to apply to the 1st 2 lines on your SHARE plan -- now, it only applies to the 1st line. The Everything Data Share was $129.99 for the 1st 2 lines on the account , and any additional lines were $19.99. The discount now is on $110 instead of $129.99, therefore effectively charging $5 more per month.

I am out of contract and am due for an upgrade to my primary line. More than likely, I will upgrade to an IPhone or Samsung. I will be charged $10 more per month for the new smartphone plus an additional $5 because now Sprint only applies the discount to the 1st line only.
