Telemarketing is especially annoying when it reaches your mobile phone, costing you money to hear a sales pitch. Be cautious in giving your mobile number to companies, and especially be aware of opting in or out of a company sharing or selling that information.
If you do give out a mobile number, be sure to tell companies that it’s mobile. If someone calls with a pitch, ask them to take you off their list, and also mention that they have called a mobile number. It’s illegal for telemarketers to use autodialers to reach mobile numbers, so they’ll likely respond quickly if you let them know.
The National Do Not Call Registry can add another layer of protection, with caveats. The list is a database of numbers that telemarketers can’t call, but loopholes allow calls from political groups, surveys, and companies with which you’ve established a business relationship. Nearly the same restrictions on sales calls apply to mobile phones already; however, if you’ve begun to receive sales calls on your cell phone, adding your number to the Do Not Call Registry (www.donotcall.gov)can be the easiest way to stop them.
If, after registering your number with the Do Not Call Registry, you continue to receive sales calls on your cell phone, don’t just hang up in exasperation. Instead, gather as much info about the caller as you can, and file a complaint using the online form at donotcall.gov
