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.

We recently switched our business landline to Voiply and had some issues after the porting process was complete. I contacted customer service, and they were able to resolve the issue quickly and get us up and running. The additional features provided by Voiply over a traditional landline phone are wonderful.

Voiply is the best phone service available. We changed to Voiply because of the length of time it took for our previous carrier to respond to us. Voiply, from the beginning, responded immediately, without delay to any request we made. Their representatives are so kind and understanding. I encourage all that read this to make the switch without delay

i decided to replace my land line and purchased a VoIP system from Voiply. I paid for one year and received two months free. This saved me 165.00 over my old plan. I received everything needed in a few days and the installation was simple. I have been using the system for a few weeks now with no issues.Glad i made the change.

One could not ask for a better voip then Voiply. I have been a customer for many years and never experienced any issues at all, until this this year between Christmas and New Years. I was not receiving incoming calls and called for assistance. One would think, and most likely expect that during this time of the season help would not be forth coming. WRONG. The tech help desk solved the issue on the call back on a day between Christmas and New Years. Solved the issue, called in on the line, left a message and life was good again. Voiply takes problems seriously and solves them as soon as possible. One GREAT company with customer service in mind. And as a bonus their plans are very affordable and reasonable.

I am using the app-based service which is more than sufficient for my sole proprietorship. It is a better price fit for me than Oomla, Grasshopper, and RingCentral. Works well with my Android and my wife's iPhone (she's my secretary). I highly recommend this service for your business line needs.

Voiply does have an A+ BBB rating. Just set it all up, was some issues with getting started, but contacted them. Initial communication was easily done through what seemed to be AI generated. Info was sent to a technician who fixed all my issues within the hour. I did not have to stay on the phone while the tech was doing their fix. Once everything was working, the tech sent me an email of his work and asked if all was good. I was able to reply, which is usually not an option to other businesses. Voiply seems to work great. Many features to learn along the way. I hope this will be a long friendship for us. I 100% would recommend this to everyone. The price is right. Just be patient for the initial set up, they are there to help, even with transferring your phone number for free, which many businesses are charging you for.

We realized our house phone was not working and I e-mailed Voiply. They replied promptly, created a ticket # for us and began work on their end. Seems our adapter was off line so they gave me instructions on what to do. I followed their directions and we were back in service. Nice and easy--thank you.
