Why you need a second phone number

I have a second number on my phone. You should, too.

Your main number? Keep that locked down for the important stuff — your bank, doctor’s office and family. But when you’re ordering takeout, signing up for a one-time deal or making an online purchase, why give out your real number? 

That’s where a second number comes in. It keeps your personal line free from spam, telemarketers and who-knows-who selling your info.

Why have one?

🔹 For privacy – Meeting new people? Selling something online? A second number keeps strangers from having your real one. It’s especially useful for dating apps or marketplace transactions.

🔹 For work-life balance – Some people reserve an extra number just for business calls or VIP contacts. This way, when you turn it off, work stays at work.

How do you get a second number?

You don’t need a second phone to get a second number. Here are the easiest ways to set one up:

📱 App-based services – Virtual phone number apps are affordable, easy to manage and don’t require a separate SIM card.

📡 Carrier add-ons – Verizon, for example, lets you add an extra number to your existing plan for around $10/month. 

What do I use? Google Voice. 

No matter which option you choose, having a backup number is a simple way to protect your privacy and cut down on unwanted calls. Once you start using one, you’ll wonder how you ever managed without it!

😂 I’m really good at smartphone advice. You could say I’ve found my calling. (OK, let’s see you write better jokes for free!)
