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.

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 learned voiply from a chatbot recommendation when looking for a cheap solution to park my old number. the customer support team is very helpful! After port the number over, I originally have difficulty to setup the voicemail and the SMS to Email didn't work. The team followed up with my case responsively. They tried several times and eventually made both work, without me fiddling with the settings I can find on the website. so far everything works as I expected and the SMS to Email super fast once it works! it's like I still using the number on my phone now!

To top it off, the support is AMAZING! They are very prompt and handle all inquiries quickly. Even the AI chat bot is smarter than most I've used. Highly recommend their services!

I appreciate the time and attention that I received from the Voiply tech support agents when I was trying to resolve an issue with my adaptor. Mike walked me through a process to restore my service via the website chat and email. When neither of these methods was successful, Ana called me on my mobile phone and walked me through the process. Many thanks to their dedication in helping to resolve this issue.

We used Voiply service for many years with trouble free service. When it came time to cancel our service (just don’t use the land line anymore) they made this very simple to do. If we ever need a landline again we will definitely be back!

With our economy changing, I am trying to save anyway I can. I saw VOIPLY on line and decided to see what they had to offer, With their help, I am able to keep my landline for half the price I was paying through the "traditional cable bundle". It took a little extra help from my end with financing, but they were extremely kind and patient throughout the entire process. Highly recommend them.
