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 my ATT to Voiply home phone service 2 weeks ago, and am extremely happy with the decision. Voiply not only kept me informed of the progress of equipments shipment, porting updat, and provided step by step installation instructions, they also responded to my questions, by phone, email, and chat, promptly with clarity. I am able to enjoy all the services, including incoming and outgoing caller ID, fax services, etc. that I had with ATT before the switch. I waited for two weeks to make sure the services run smoothly before I posted my opinion about voiply and I can say that I am extremely happy with the results.

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.
