The just announced Lumia 650 smartphone will indeed be sold in the U.S. via AT&T's no-contract subsidiary Cricket Wireless. Microsoft's own support page for the Windows 10 Mobile phone has a link to a PDF user guide for the phone with "Cricket" in its title.
The support page confirms our previous report that the Lumia 650 will be available via Cricket Wireless. We expect the phone to go on sale from the carrier sometime in April. Pre-orders for the Lumia 650 are already live in parts of Europe for a launch on Feb. 18 for prices around £160/€230. There's no word yet on how much Cricket will charge for the Lumia 650 but Microsoft suggested it might be sold for under $200 in today's announcement.
