Shortly after Samsung Canada’s announcement detailing the relief of the Galaxy Note 7’s wireless capabilities, there are signs that US units may see Wi-Fi, Bluetooth and cellular connectivity go — along with everything else.

In an SMS missive from US Cellular obtained by The Verge, Samsung has decided to initiate its firmest measure yet in getting Note 7 users to exchange their phones — by sending out an update that will prevent the device from charging.

“THE PHONE WILL NO LONGER WORK,” the message concludes.

Since US Cellular is placing the responsibility of this software modification squarely on Samsung, it is likely that the outstanding recalled phones on all other US carriers will get the same update. This goes beyond the pale of limiting the battery’s charge to 60 percent and is closer to what was thought to happen to French Note 7 units — a kill switch.

Samsung declined comment on the issue. US Cellular did not respond to a request for comment.
