Virtual Cell Phone Numbers & Fax Numbers

eCall offers virtual mobile numbers and fax numbers for receiving, sending, and forwarding messages.

You can rent these two types of receiving numbers

Receiving numbers allow your recipients, such as customers and employees, to reply to messages. You can also use them to forward incoming messages as voice messages. To rent virtual mobile numbers, you need an eCall user account.

To do this, go to “Numbers” in the navigation menu of your eCall account to find the settings for renting virtual numbers. Open an account here for free and rent virtual numbers.

Rent virtual mobile numbers

Having your own virtual mobile number allows you to receive*, forward, and send SMS messages online. Furthermore, every received message can be forwarded to one or more recipients. This enables customers and employees, for example, to reply directly to text messages. Furthermore, forwarding can be done via voice message (TTS), email, SMS, fax, or HTTPS – even across multiple channels simultaneously (e.g., SMS and email).

Rent your own fax number

eCall allows you to receive, forward, and send faxes using your own virtual number. All received fax messages are visible in the logbook of your eCall account. From there, you can forward them as PDF files to any email address. If you wish to keep your existing fax number, you can redirect it using the Swisscom “Call Forwarding” service.

* Receiving access & activation codes from social media providers such as Google, Facebook, Microsoft, Apple, WhatsApp, and other providers via eCall virtual numbers:


Receiving activation, security, or access codes on eCall virtual mobile numbers is only available to customers with a Business account. For all other account types, this feature is blocked for security reasons. The sender “bet365” is blocked for all account types.

Please contact us if you have further questions. We’d be happy to assist you in opening a Business account.
