AT&T wants subscribers to have a merry Christmas this year. It also wants some of the people who have been fleeing its network in searching of cheaper smartphone plans to stay put. As such, the carrier on Thursday announced a brand new set of service plans that are far more consumer-friendly. AT&T is still making plenty of money on them, of course, but several of the plans offer significant savings compared to the older plans they replace. What’s more, the new plans finally — FINALLY — take smartphone subsidies into account to an extent, and they automatically drop in cost by $15 per month once your phone is paid off. Or, if you bring your own phone or opt for one of the carrier’s AT&T Next plans, your service is $15 cheaper per month from day one.

Remember our discussion about how phones like Google’s great Nexus 5 are really only a value if you use them with a service plan that doesn’t factor in handset subsidies? Well AT&T’s new Mobile Share Value plans move a big step closer to accomplishing that. They don’t quite provide value that approaches some other offerings out there, but those options also don’t provide the coverage and data speeds afforded by AT&T’s network.

So what do these new plan prices look like, exactly?

They work just like the current Mobile Share plans: Subscribers pay a set fee per device — in this case, $40 per subsidized smartphone, $25 per AT&T Next phone or contract-free smartphone, $20 per feature phone and $10 per tablet — and then the plans tack on a data charge, which varies depending on how much data the subscriber chooses. Data is shared between all devices on a plan and options range from $20 for 300MB of data per month to $375 for 50GB of data per month. All plans still include unlimited talk and text.

But even if we forget about the new plan prices for a moment, customers who use off-contract devices will save $360 every two years just from the fact that these new plans drop by $15 per month for unsubsidized devices.

To make things a bit more clear, BGR has tables that lay out every single new AT&T Mobile Share Value plan and compare it to the plan it replaces. To make things as clear as possible, we’ve made two tables; the first shows plan pricing when you use a new Mobile Share Value plan with one smartphone and the second shows the total cost of the plan on an account with two smartphones.

Some important notes here:

First of all, these new plans do not technically replace the current Mobile Share plans. Subscribers on a current plan will not automatically be moved over to a new one. If you are on an old plan though, we highly recommend you call or go online this coming Sunday when the plans become available and switch immediately. There are a few instances where prices go up on these new plans so you’ll have to crunch some numbers, but the overwhelming majority of scenarios will see savings.

While the prices of what are likely the most popular Mobile Share plans remain unchanged, they will still drop by $15 per device each month as soon as your current contract expires. If you’re on an AT&T Next plan or if you aren’t currently on a contract, your service cost will drop by $15 per device immediately. Most of the new plans do offer savings compared to the old versions though, so you’ll spend less money each month even if you’re still on a contract.

Your contract will not be extended when you switch to a new Mobile Share Value plan.

Lastly, AT&T is also introducing a new option for AT&T Next customers. The current plan allows subscribers to purchase a new smartphone for $0 down and spread the payments out over a period of 20 months, and it also allows them to trade in their current phones and upgrade to a new one every 12 months. The new plan is the same, but payments are spread out over 26 months instead of 20 and upgrades can be had every 18 months. This is a decent option for people who upgrade less frequently — phones cost the same amount but spreading payments across more time obviously results in lower monthly payments.

AT&T’s new Mobile Share Value plans go live this coming Sunday, December 8th, as does the new 18-month AT&T Next plan.
