In the latest Sprint Playbook we're seeing another plan change, this time to the mobile hotspot feature. Starting Oct. 2, current and future customers will have a 5GB limit when using the mobile hotspot add-on to their plan. Data used on the phone itself isn't being limited (other than the 300MB "roaming" data cap, it's still all you can eat), but both 3G and 4G data used via the hotspot feature will now be subject to a $0.05 per MB charge once the 5GB cap is reached. Before, 4G data was unlimited.
A similiar change is being made to mobile broadband devices like aircards, tablets, and portable hotspots that used to have unlimited 4G data. It could be worse, but we're pretty sure that even though most don't subscribe to the hotspot add-on and use other methods, there will still be plenty of wailing and gnashing of teeth. Can't stop changes folks.
