LOCAL NUMBERS

Why Does Area Code Matter?

A local phone number provides several significant benefits to a small business. Firstly, it enhances the company's presence in the local community and makes it appear more accessible to customers.

This local presence further establishes trust and credibility, as customers generally feel more comfortable dealing with businesses they perceive as local. From a practical standpoint, a local number is also more convenient and often cheaper for customers to call compared to long-distance or toll-free numbers.

Additionally, a local number serves as an effective marketing tool, reinforcing the association of your business with the local community. Lastly, having a separate business number helps maintain the privacy of your personal number, creating a clear boundary between professional and personal communications.

How to Spot a Spam Call or Text

Beware of unknown senders, urgent action requests, and too-good-to-be-true offers. Check for spelling errors and unfamiliar URLs. When in doubt, don't click or reply. Always verify from official sources.

Check for unknown numbers

Check for Unknown, Unfamiliar Numbers

A common sign of a spam call or text message is that it comes from an unknown or unfamiliar number.

Sometimes, these numbers may even appear to be from another country. If you don't recognize the number, be cautious.

Don't answer calls or reply to texts from numbers you don't know, especially if they aren't leaving messages.

Beware of too good offers

Beware of Too Good To Be True Offers

Spam messages often contain offers that seem too good to be true.

These could be promises of free vacations, big discounts, or large monetary rewards. As a rule of thumb, if something seems too good to be true, it probably is.

Always verify such offers from a reliable source before responding.

Look out for personal information requests

Look Out for Urgent Requests for Personal Information

Spam callers or texters often try to create a sense of urgency to get you to provide personal information.

They might pretend to be from your bank or a government agency, claiming there's a problem with your account or that you owe money. Never provide personal information in response to an unsolicited call or text message. When in doubt, hang up and contact the entity directly using a number you trust.

What Real People Say About Us?

Experience why Voiply has become the top-rated home phone provider, trusted by over 50,000 satisfied customers.

I love the ease of purchase, the online dashboard is transparent about services and features, the customer service has always been topnotch, and you can't beat the price! I have the landline phone for my kids too young for cell phones and it's an added safety feature should I need to call 911 as the number is tied to my physical address. Worth every penny!

Voiply people and even their BOT have been very helpful. I've had the phone equipment since March 2025 but I hadn't tried to set it up until tonight. I had to wait to get a call back, but once the call came through, a wonderful agent named Blest helped me understand how to complete the process. Thank you!

We have cut the cord with Xfinity’s ever raising prices for over 6 months now by using Voiply phone system. It was VERY easy to set up and works fine. We had an issue with not showing caller ID after 6 months and it was resolved within a day. I will definitely continue to extend our membership beyond the 1 year that we initially signed up.

I changed internet providers to T-MOBILE and was sent a 5G Gateway router. I read that there were issues because it has to be configured to Voiply.On two occasions I could not receive or call out with Voiply and had to use my cell phone. I contacted customer service and they fixed the issue and told me what to do if it happens again on my end and if that doesn't work call customer support. They were easy to work with for someone that's a senior and not computer savvy.

I'm ecstatic to have found Voiply for my business phone service. I tried a couple of other services and was so dissatisfied I cancelled and started my search anew. I followed the trail of positive reviews straight to Voiply! Account creation and setup was a breeze, and I was ready to start taking calls in less than 20 minutes. I'll be sharing my experience with other business owners!

Voiply provides excellent service with customer service that wowed me from the start. I had to move my phone away from landline and Voiply was the only service that had clear instructions and reasonable costs. Then I needed to clarify some questions, so I called and I was able to speak to a real person who understood what was going on, saved me money on the plan, and was friendly and knowledgeable. When it came time to port the number, I had clear updates and I had a date. On the morning of the date, the number switched and I was live. It was so smooth, it was like nothing even changed. I'm so thrilled that I found Voiply, I highly recommend this service and this business.
