T-Mobile today announced that the pre-orders for the Samsung Galaxy S6 and the HTC One M9 in only 10 days have been through the roof.

The Galaxy S6 and Galaxy S6 edge went on pre-order on T-Mobile on March 27, and in 10 only days, the total pre-orders of the device are already nearly double of that of the Galaxy S5.

The carrier also mentioned that the pre-orders for the HTC One M9 — which has largely received negative reviews — has also surpassed that of the HTC One M8 in 10 days. The One M9 also went on pre-order on T-Mobile on March 27.

Since T-Mobile began shipping—and selling—the Galaxy S 6 and Galaxy S 6 edge on March 27, customer response has been through the roof.  In just the first 10 days, sales of the new Galaxy S 6 series at T-Mobile are already nearly double those of the Galaxy S 5 – previously the most popular Galaxy phone ever at T-Mobile.  Likewise, in the first 10 days of HTC One M9 sales, the flagship phone has already surpassed sales of the HTC One M8 during the same time period.

Both handsets will be available from April 10 across T-Mobile’s retail stores in the United States.
