Sounds like Bryan Singer's H+ series.
H+: The Digital Series takes viewers on a journey into an apocalyptic future where technology has begun to spiral out of control, a future where 33% of the world's population has retired its cell phones and laptops in favor of a stunning new device – an implanted computer system called H+.
This tiny tool allows the user's own mind and nervous system to be connected to the Internet 24 hours a day. But something else is coming… something dark and vicious… and within seconds, billions of people will be dead… opening the door to radical changes in the political and social landscape of the planet - prompting survivors to make sense of what went wrong.
The trailer is found here and the rest of the series is here.
