Apple recently rolled out a carrier update for Verizon iPhone 5s which fixes a bug that many users were previously complaining about, Wi-Fi issues. In some cases, the iPhone 5 was using cellular data even while connected to a Wi-Fi network, eating away at data allowances for many. Apple created a new support page regarding the fix, providing step-by-step instructions for users on what to do to resolve the issue. The installation guide states the following:
- Tap Settings > General > About.
- Wait for the following alert to appear:
- Tap OK to install the update.
- Hold the Sleep/Wake button down until you see "slide to power off".
- Slide to power off.
- After the device powers off, hold the Sleep/Wake button to turn your phone back on.
Note: To finish the installation of the update, your iPhone 5 must be turned off and then on again.
After your iPhone restarts, tap Settings > General > About, then scroll down to Carrier and verify that "Verizon 13.1" is displayed.
Although this update is for Verizon Wireless customers only, some posts in the thread mentioned that they had similar issues with AT&T as well, although the validity of their statements has not been confirmed. Different threads are also pointing to owners of older iPhones, such as the iPhone 4 and 4S, also complaining about a rather large amount of data being used after installing iOS 6.
The issue doesn’t appear to be tied to any specific carrier and recent posts point to data usage peaking during overnight hours. It’s also unclear whether Verizon will refund users who were affected by the unintentional data usage and Apple hasn’t made any announcements regarding what caused the issue. At least Verizon customers who were affected by the issue can resolve it and not have to worry about it going forward.
