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.

Joined Voiply because I want to be able to use the app when traveling Internationally. The service was easy to use . Just dial the number in the app and you had a very clear connection to person you were calling. Since I am not traveling i did not need this connection. Their customer service is much better than 95% off other companies.

Due to my absence for 5 months, I had discontinued my internet service with another provider. To my surprise, voicemail was still working during this time and I was immediately notified via email whenever a call came in. The messages that were left showed up in detail which I appreciated. Upon reactivation of the modem for internet with that other provider, I had an issue with the phone connection. I contacted Voiply which fixed the problem within a relatively short time. I am very satisfied with the service that I received.

This was the easiest transition of a phone service ever! Everything transferred right on time, received the voiply box within days, plugged it in and done! No more monthly bill from a phone company. I wish I would have known about this service years ago.

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.

I have had Voiply for the past 3 years and their service is amazing. The quality of the calls are clear. The customer service reps are so helpful. Their annual plan averages to about $13 a month(after taxes and fees) which also includes free international calls on about 50 countries. Nobody can beat that price! I've looked at other companies and many have bad reviews from the BBB. Their protection plan costs $1.00 a month. VOIPLY is rated A+ from the BBB. I highly recommend them!
