Explore how a mobile extension brings your phone system to every smartphone using eSIM, enabling a secure number on mobile for remote, hybrid, and field teams.
In 2026, work rarely happens in one place. A call might come in while an employee is at home, on the road, or between meetings. When business phone systems are tied only to desks or apps, that flexibility quickly turns into friction for modern teams.
Recent global surveys show that about 22% of workers now operate remotely, 83% prefer hybrid arrangements, and 73% report higher productivity under these flexible setups. Business communications platforms must adapt to how work happens today, supporting remote employees, hybrid teams, and field staff on the mobile devices they rely on every day.
Hybrid work is here to stay. Omdia estimates that frontline workers represent about 60% of the total workforce, making reliable mobile connectivity essential.
That’s exactly the reality IPFoneGo! was designed for. It is not a separate mobile line, but a business mobile extension of your phone system, powered by eSIM for business. It puts your office number, features, and system-level policies directly on your team’s smartphones, keeping work and personal calls separate while maintaining a consistent business number.
What Is a Business Phone Extension?
A business phone extension is a number within your phone system that lets employees make and receive calls using the company’s caller ID and features.
With IPFoneGo!, that extension delivers enterprise-grade calling functionality (such as voicemail, call forwarding, and conferencing) through the same mobile network your team already trusts.
Why Does a Mobile Extension Matter Now?
A mobile extension connects your business phone system to every worker without adding disconnected mobile services or extra hardware. Your business number travels with employees, keeping call flows, voicemail, and features consistent wherever they work.
