Samsung announced that the Galaxy S4 will be available from seven US carriers and seven retailers beginning this month. Both Sprint and T-Mobile today announced plans to sell Samsung's flagship for $150 in 16GB form.

T-Mobile's plan includes its now-standard device payment installments, while Sprint is discounting the phone from its normal $250 price through a $100 instant credit if you switch from another carrier.

Sprint will offer pre-orders starting on April 18th, with an actual launch on April 27th. T-Mobile isn't giving customers the same opportunity to buy in advance, although they will get to take the Galaxy S 4 home a few days earlier, on April 24th.

Verizon, AT&T, US Cellular, Cricket, and C Spire haven't yet announced dates and pricing, but they should all have it available before the end of April. You will also be able to pick it up at various retailers such as Best Buy and Best Buy Mobile, Costco, Radio Shack, Sam's Club, Staples, Target and Wal-Mart.
