Using a Virtual Phone System to Call the US From Korea

Though dialing a number in the United States from South Korea is simple, it is costly. Besides, people are always reluctant to pick an unknown international number. That’s the problem a virtual phone system can solve. 

A virtual phone system allows you to purchase local phone numbers that customers would pick and even take your business positively. Besides, your local (US) customers can contact you without incurring international charges. 

The best part about the US virtual phone numbers is that you don’t need to be physically present in the US to use local numbers. You can sit in South Korea and call your customers in the US as if you are in their city. 

Establishing a local presence also makes it easier to attract customers and build rapport with them

But that’s not it.

There are several other reasons to use a virtual phone system for your business. 

1- Reduce Calling Expenses

Since you will be making hundreds of calls (to attract customers), you are looking at a phone bill of thousands of dollars every month without a virtual phone system. 

But why spend international charges when you can pay less with local phone numbers. Calls to the United States from Korea with CallHippo business phone systems start from as low as $0.01.

2- Improve Your Advertising ROI

If your ads have a US virtual phone number with a local area code, more people are likely to call you than if you have an international number. You can even get featured in local directories and business listings. 

3- Work From Anywhere

A virtual phone system gives you the flexibility to work from anywhere in the world. Besides, you won’t have to stick to your desk to make or receive calls. For instance, with CallHippo mobile app, you can use your smartphone to manage business calls. This ensures you don’t miss an opportunity even if it comes outside your business hours (which is highly likely as the time zone in the US and Korea are different). 

4- Highly Scalable

As your business in the US grows, you will need more people to handle incoming and outgoing calls. However, with a traditional phone system, you will have to purchase hardware and install telephone lines in your office. 

On the other hand, a virtual phone system allows you to scale your sales and support team at little to no extra cost. All you will need to do is upgrade your premium or add a new user, which will cost you only a few dollars. 

5- Advanced Features

Entering a new market is never easy. However, a virtual phone system comes with a myriad of features, such as call recording and call center analytics, that can help you understand your potential customers better. 

You can then use the insights gathered using these features to better tailor your services and offerings to increase the chances of sales.

Wrapping Up

The United States is one of the best countries to expand your business. And when you do, follow the steps mentioned above to call your prospects in the US from Korea. Also, make sure to buy a US phone number to minimize your calling expenses and boost your advertising ROI.
