There's now an ongoing race for carriers to give the best deals for Samsung Galaxy S7 and S7 Edge to ramp up their sales and increase consumer base.

The top three mobile phone carriers in the US now are Verizon Wireless with 140.1 million consumer base, AT&T Mobile with 128.6 million and T-Mobile with 63.2 million. So the comparison on the deals and promotions for Samsung Galaxy S7 and S7 Edge will be limited to these three providers.

In terms of the upfront price comparison, AT&T offers $695 for the Samsung Galaxy S7 and $795 for Galaxy S7 Edge; Verizon offers $672 and $792 for the two units; while T-Mobile appears to be the cheapest at $670 and $780, respectively.

However, as PC Mag reported, the promotions will make a difference in how the consumers can maximize their contracts with the three major mobile phone carriers.

For instance, while AT&T appears to be the more expensive, it does give consumers a free gear VR headset as well as a free Samsung Galaxy S7 under the "Next 24" installment plan. In comparison, Verizon is also offering a free VR headset or a Gear 2 smartwatch under the company's payment plan.

Under the T-Mobile installment plan, clients can get the second phone for free.

"T-Mobile will be offering a prepaid gift card with the full balance of the phone on it. This is all in addition to the other existing offers, like a free year of Netflix," said Android Central.

Below is comparison for the three carriers' deals for Samsung Galaxy S7 and S7 Edge:

Verizon: Galaxy S7 at $28 per month for 24 months, and Galaxy S7 Edge at $33. 

AT&T: Galaxy S7 at $23.17 a month for 30 months, and Galaxy S7 Edge at $26.50.

T-Mobile: Galaxy S7 at $27.91 for 24 months, Galaxy S7 Edge at $32.50.
