The Calls You're Losing Right Now

Are your mobile teams using personal phone numbers for business?

From the company’s perspective, it never happened.

What’s the impact?

Calls aren’t recorded or logged in your CRM
Promises can’t be verified or audited
Customer knowledge leaves with employees
Personal privacy is put at risk
Sales performance can’t be measured or improved

Without visibility, managers can’t coach, compliance teams can’t audit and AI can’t improve what it can’t see.

Wildix eSIM fixes this

Every call is automatically tracked, recorded and synced to your CRM, giving you the same professional oversight as a desk phone with the full mobility of a smartphone.

The Visibility Gap: Why Apps and Hardware Fall Short

End app fatigue

While apps are excellent for collaboration, busy employees often default to their phone native dialer because it’s faster. Wildix eSIM works inside that regular dialer to capture 100% of activity. This ensures you never lose valuable data without forcing your team to change their habits or learn new software.

Replace the hardware headache

Desk phones and DECT systems are great for fixed locations, but they require shipping, wiring and maintenance. Wildix eSIM provides the same professional features, like transfers and AI recording, through a purely digital setup. It allows you to scale your team instantly with no plastic on the desk.

From Invisible Calls to Actionable Intelligence

Every call made with Wildix business eSIM becomes part of your company’s communication intelligence

Calls are automatically recorded, transcribed and summarized by AI

Wildix eSIM FAQs

What is an eSIM for business?

An eSIM for business (also called a corporate eSIM), is a virtual SIM card that lets your business phone number work in your phone’s regular dialer. You don’t need to open an app, and business calls work exactly like personal calls, just with a different number.

Who should use the Wildix eSIM?

It’s perfect for people who work outside the office, including sales teams, technicians, real estate agents or anyone who needs to keep their business and personal numbers separate without carrying two phones.

It’s also great for companies that want to stop buying separate work phones.

What do I need to start using it?

You need a Wildix system with CLASSOUND phone service and a CLASSOUND phone number (you can transfer your current number or get a new one). Each business eSIM includes data, and you activate it by scanning a QR code.

How is this different from the Collaboration 7 or x-bees apps?

Our apps are great for messaging and video calls, but the Wildix eSIM works in your phone’s built-in dialer. So, you don’t open any app, you just dial normally.

It’s for people who mainly make phone calls and want the simplest experience.

Can I have numbers from different countries?

Yes! You can get eSIMs from different countries, so you can call customers using a local number from their country, even if you’re somewhere else. This helps people trust you more and answer your calls more often.

Is the Wildix eSIM secure?

Yes. All calls go through your company’s secure phone system. Every call can be logged, recorded and tracked, so you meet company rules and legal requirements.

What happens to my recordings and data?

Everything (recordings, transcripts and AI summaries) automatically saves to your existing systems like Salesforce, and can be accessed inside the app in call history and analytics. Nothing gets lost, and everything stays organized for compliance, training or customer service.
