Other Ways To Have 2 Phone Numbers On One Phone
There are several ways I’ve used to get two phone numbers on one device, each offering unique advantages. Here’s a breakdown of the methods that work best:
1. Dual SIM Phone
A dual-SIM phone allows me to use dual SIM cards in one device. A SIM card (Subscriber Identity Module) is a small chip that connects your phone to a mobile network, and dual SIM phones have two SIM slots.
For example, I can use one SIM for work calls and the other SIM for personal calls. It’s also great when I travel internationally, as I can keep my mobile number while using a different carrier for cheaper data and calls.
Most dual-SIM devices have two SIM card slots that let both lines stay active.
2. eSIM Technology
With eSIM, I can digitally activate a second phone number without the need for a physical SIM card. Many modern mobile phones support eSIM, so I can easily add a business number to my phone.
For example, I can use my main SIM card for personal calls and set an eSIM with a secondary number for client calls. This option is convenient because I do not need to manage many physical SIM cards or worry about SIM card slots.
- eSIM support varies by carrier, so make sure to verify with your provider before trying to activate a second number using this technology.
3. VoIP-Based Solutions
I have also used VoIP services like CallHippo to get a second line without the need for any physical SIM. This method allows me to call and receive calls on Wi-Fi or mobile data on my mobile device. In fact, businesses can save an average of 30% to 50% by switching to VoIP, and in some cases, the savings can reach 50% to 75%.
For example, I have used it to set up a business line, keeping my personal life separate, all within the same device. In addition, services like CallHippo let me choose from local or international numbers so that I can have a cell number anywhere in the world.

How Do I Know Which Number Callers Are Trying To Reach?
It is easy to manage two phone numbers on your cell phone when you can quickly identify which number is receiving incoming calls. Most dual SIM devices will allow you to label your line (work or personal). So there is a line of communication to distinguish between work and personal calls.
As an example, I use a professional ringtone for business calls and a casual ringtone for personal calls. You can also set a different voicemail greeting for each line. The number that is dialed, displayed in the caller ID, is differentiated. I can also switch between different lines while making an outgoing call from my mobile device.
