You often need to register a foreign platform at work and need a local mobile phone number, or you often need to use multiple numbers at work, how to add a second number to your mobile phone for business purposes and stop carrying two mobile phones? Some phones come with dual SIM or some with eSIM (embedded SIM), but most don’t. That’s why these apps (also known as eSIMs for electronic SIMs) enable you to have a free secondary virtual mobile number, also known as a “temporary disposable number”. They require an internet connection to function, and because they’re VoIP, they’re probably the best virtual phone system for small businesses because, unlike a PBX, you don’t need to buy any hardware.

       It helps you separate your personal life from work—just like business email does when creating a professional or separate identity. As a virtual office phone system line to your assigned business number, you have all the benefits of a professional phone line and you can easily use mobile or desktop applications on devices you already own, including your mobile phone, smart watch, tablet , PC and Mac. Compatible with Android 8.0 Oreo / Android 9.0 phones such as Samsung Galaxy, Huawei Mate, Oppo, Vivo, Xiaomi, Nokia, and Apple’s iOS iPhone X.

Forget about those dual sim adapters for iPhone, this virtual number app is a better solution. The advantage is that both numbers run continuously, while the adapter can only activate 1 sim card at a time. Another advantage is that these numbers are one-time use, once the old number gets too many spam calls, you only need to register a new number. Also great for prank calls.

1 – Google Voice |  US only

Google Voice provides one number for all your calls, voicemail as easy as email, free long-distance calls in the US, low rates for international calls, and lots of calls. This is a virtual phone number forwarding service. The virtual number is tied to your Google Hangout, which means calls and texts are made through the Hangout. To subscribe to a toll-free number, click the “Settings” button, then go to the “Phone” tab and integrate it with your existing phone number. That’s as good as an eSIM for international calls.

2 – Burner |  Pay with credit card
