If you have an older Amazon Kindle with 3G internet, take note that you may not be able to wirelessly access and download new content anymore starting in December. As The Verge reports, Amazon has sent out emails to owners with old Kindles, telling them that previous-generation devices will lose internet access after mobile operators transition from 2G and 3G networks to 4G and 5G.
The e-commerce giant listed the particular devices that will be affected by the switch in its FAQ page. It noted that the first- and second-generation Kindles, as well as the Kindle DX, won’t be able to connect to the internet at all since they don’t have WiFi connectivity to fall back on. The other devices in the list are the Kindle Keyboard (3rd Generation), Kindle Touch (4th Generation), Kindle Paperwhite (5th, 6th and 7th Generation), Kindle Voyage (7th Generation) and Kindle Oasis (8th Generation), all of which have WiFi connection.
You’ll still be able to access your books on an older device and can do wired transfers if you want, though. And if you have a newer 4G or WiFi-only Kindle, you won’t be affected at all. In its email, Amazon included a code customers can use to get $50 off a new Kindle Paperwhite or Oasis, along with $15 in eBook credits. You may want to check your inbox to see if you got the company’s notice in case you’ve been looking to upgrade anyway.
