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.

I switched carriers but wanted to keep a "stand-alone" phone. Voiply sent me the hardware, and as soon as I plugged it in my "landline" phone started working. I didn't even have to call my old carrier and get a Transfer PIN. Voiply was so easy to install and set up.

Yes, we still have a landline telephone. Voiply has been an excellent provider for years. The system works smoothly, including voicemail. If I ever have a question they respond very quickly. I always feel that I am chatting with a real person, not some AI-generated bot. The price is very reasonable and I recommend them highly.

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'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.

All I can say is it was SEAMLESS! I had no idea this service even existed until my son shared it with me. I’ve had my number for 45 years and didn’t want to lose it but had to ask if it was cost effective. This made my answer easy…NO it wasn’t until I parked it with VOIPLY. Thank you for the service and for making the switch so easy.

If you’re a freelancer or solopreneur looking for a reliable phone system, Voiply is definitely worth checking out. The call quality is super clear, even on their starter plan—which also includes built-in CNAM (a nice bonus you usually pay extra for elsewhere). Right now, they’re offering 50% off, which makes it a no-brainer if you’re just getting set up or want to upgrade your setup without breaking the bank. What really impressed me, though, was their support team. They're available 24/7, quick to respond, and they actually know what they’re doing. That kind of service is rare. Also, their KYC (Know Your Customer) process adds a layer of professionalism that shows they take security and compliance seriously—great if you’re working with sensitive client info. Overall, Voiply just gets what solo professionals need: clarity, support, and a system that works. Big fan.
