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 switched to Voiply and could not be happier. The phone works great, easy to set up and great service. We did have one technical issue at first (Caller ID was not working), Voiply worked with us and got it fixed. Would highly recommend, and they are much cheaper than the cable service we were using.

I signed up for Voiply's Park Your Number service, as I no longer needed a home landline and found myself inundated with spam calls that were constantly disrupting me when I was working from home. I really wanted to keep my phone number as it I have had it for decades and there is no way I could remember all of the places that I have listed it as my main contact number, so this was a great solution to not severe that history but still provide me a break from these incessant solicitation calls... Now I am able to get email notifications when people leave messages so I can easily review them when it is convenient for me. I can also log in to my Voiply account and review a full log of calls, see which ones left or didn't leave messages. It is a joy to see the tally of calls (most of which were of no interest to me!) and to appreciate the amount of disruptions that have now been avoided. That alone is worth the very small price for the service. I only wish I had found out about this sooner. Bravo Voiply, bravo!

I had a little problem getting a transfer code from my previous phone company. Voiply was very patient with me. I received my equipment very quickly, and the transfer was processed smoothly. I have had no problems with my new plan.

I've been very happy with Voiply. I've had to use the service twice now and it has been very easy to start, stop, and then start again. The latest restart was very easy especially now that Voiply has added an AI layer to their chat and overall system. When I've needed an agent they have been available and very helpful. The porting process has been great and I feel safe and comfortable with Voiply holding a number for me.

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

Amazing customer service! I have to say, the communication from this company is stellar; they were very proactive; sending emails with order status updates, sending literature before I received the adapter, so that I could familiarize myself and be ready to install when it arrived. Unfortunately I don't have a compatible modem/router. (Most are compatible and can be tweaked, but I happened to have the one that wasn't.) Their tech support was brilliant, offering a couple of solutions, but I ended up returning the adapter. The customer service reps were very helpful with the return process as well. I will definitely reorder from Voiply when we're ready to get a compatible modem.

I recently signed up for Voiply and the setup and install was extremely easy and worked beautifully right out of the box. The calls are clear and sound very good. The Voiply web settings are also easy to navigate and there are lots of options to customize our phone settings.

I had a problem with the phone system. No messages and no dial tone. Got in touch with Voiply and they worked with me to get the system up and running. They worked with me to reset the box a couple of times and we had the system up and running shortly after that. The people that helped took their time and helped me to find how to adapter running again. Thanks for the help.
