T-Mobile is the first carrier in the U.S. to release the Android 5.1.1 Lollipop update for Galaxy S6 and Galaxy S6 Edge users. And now it is offering the 64 GB variants of both flagship phones at the price of the 32 GB versions for a limited period.

Users who are looking to purchase the Galaxy S6 and S6 Edge through T-Mobile may want to wait until Wednesday, because from then the carrier will be selling the 64 GB Galaxy S6 and S6 Edge at the cost of their 32 GB versions, reports TMO News. Furthermore, those who are interested in purchasing the 64 GB variant will be able to get the 128 GB model at that price.

The promotional offer will let users purchase the 64 GB without any down payment. Hence, buyers will be able to save $80 on this model. Likewise, those who purchase the 128 GB model will need only a down payment of $99. On this model, buyers will be able to take advantage of $100 savings, states Android Central.

Those who are interested in this offer can visit the T-Mobile website or its retail outlets. The offer will expire on Saturday.

After the poor sales of the Galaxy S5 in the previous year, Samsung rolled out the Galaxy S6 and Galaxy S6 flagships with a new glass and metal combo design.

The Galaxy S6 and the Galaxy S6 Edge are fitted with Quad HD screens of 5.1 inches, but the S6 Edge is flanked with a dual-edge curved display.

Both models are powered by the Exynos 7420 chipset with 3 GB of RAM. Both feature a 16 MP camera on the rear panel and a front-facing selfie shooter of 5 MP.

As mentioned above, the S6 and the S6 Edge come in three inbuilt storage variants of 32 GB, 64 GB and 128 GB. However, both the devices lack an external microSD storage slot. The S6 is powered by 2,550 mAh battery. The S6 Edge contains a bigger 2,600 mAh battery.
