If you’ve been waiting to get your Samsung Galaxy S4 on T-Mobile, then today’s the day to place your order online. The carrier is offering the 16GB model for $149.99 upfront, then $20 per month for 24 months on its new “Uncarrier” Simple Choice plans.

AT&T and Sprint have been selling the HTC One in the United States for several days now, but both carriers have only had the silver model on offer. Those holding onto their cash until the black version is available will be pleased to know that it’s now being listed as “coming soon.”

If you’ve already placed your order for a new Samsung Galaxy S4 on AT&T, you’re probably impatiently awaiting its arrival on April 30. But if you’re lucky, you may get it several days early. The carrier has begun informing some customers that it is shipping the device earlier than originally expected, with delivery as early as Thursday, April 25.

Verizon Wireless has announced on Twitter that it will begin selling the new Samsung Galaxy S4 on its 4G LTE network in May. The carrier hasn’t provided us with a specific date, but it has promised that more details will be available soon.

AT&T opened preorders for the Samsung Galaxy S4 this morning. The 16GB model costs $200 with a two-year carrier contract, or off-contract for $639. The S4 is currently available in two colors: “Black Mist” and “White Frost.”

According to AT&T’s website, preorders will ship Tuesday, April 30th and arrive on Friday, May 3rd. Some users were reporting issues with AT&T processing orders earlier this morning, but hopefully the issues have been fixed since then. A 32GB model isn’t available for preorder yet, but don’t be surprised to see it appear soon.

US Cellular, a smaller U.S. carrier, also started accepting S4 preorders today.
