How to Disable Verizon's Wireless Tracking Supercookie

Back in January, Verizon Wireless customers discovered that the company was tracking their mobile Web browsing via a "supercookie" built into their smartphones, which did not disappear even after clearing one's browser cache. Although Verizon did not seem to put this information to any harmful (or even inconvenient) effect, many users still saw it as an invasion of privacy. Now users can get rid of the supercookie, but they'll have to be proactive and follow a few simple steps.

First, you should know that the supercookie is enabled by default. Unless you have already disabled it, it is still active on your phone, gathering your online habits and transmitting them back to Verizon in order to give advertisers a better profile of you. If such practices don't bother you, there's no need to deactivate the supercookie; indeed, you may get a relevant ad or two the next time you browse the Web on your phone.

Otherwise, you have three options for getting the supercookie off your system: Using the Verizon website, using the My Verizon app on your phone or calling Verizon directly.

On the Web

Here's how to disable the supercookie using an Internet browser:

1. Go to the Verizon Wireless website.

2. Sign into your account.

You will need both a mobile number and a password. If this is your first time logging in, you'll have to register. Just click the Register link, and the website will walk you through the process.

3. Click on View Profile, then Manage Privacy Settings.

You'll have to scroll all the way down; Privacy Settings are very well hidden.

4. Scroll down to Relevant Mobile Advertising.

Find your phone line and select "No, I don't want to participate in Relevant Mobile Advertising." Then click Save Changes. You're done!

My Verizon App

Here's how to disable the supercookie using the My Verizon app:

1. Open the My Verizon app.

2. Select the Profile tab.

3. Tap on Manage Privacy Settings.

You may have to reenter your password here if you have not used the app in a while.

4. Select Relevant Mobile Advertising.

You may see a screen explaining what Relevant Mobile Advertising is. If so, click Continue (and "Do not show this again" if you don't want to see it again).

5. Tap on No to opt-out the desired lines.

Then click Save, and you're good to go.

On the Phone

For those who prefer old-school measures, you can also call Verizon at 1-866-211-0874 and follow the pre-recorded instructions.
