eCall Dialin – Former SMS Single Account from Swisscom

Since 1 February 2013 Dolphin Systems AG (since 1.10.2019 F24 Schweiz AG) operates eCall dialin the former service “SMS Single Account” from Swisscom.

Service takeover from Swisscom

F24 Schweiz AG operates Swisscom’s former “SMS Single Account” service. The takeover was completed seamlessly. However, Swisscom has decided that by the end of 2015, dial-up via 079 xxx xx xx will no longer be possible. We also operate the Swiss SMS Gateway eCall.

Also visit our eCall Blog and learn more about SMS, fax and business messaging.

However, access to this service is still guaranteed via the existing number 0900 900 941 (CHF 0.39/minute). You can find out more under “Change 079 to 0900”.

Change from 079 499 XX XX to 0900 900 941

Swisscom has discontinued the service

In 2015, Swisscom will discontinue 079 access. Not affected by this, the number 0900 900 941, which we also took over from Swisscom.

An example

This is how the application could work:
Your company has a modem connected to a telephone line. On the second page of the letter, this telephone number is listed as a “dial-in number”. The modem uses this connection to dial the number 079 499 XX XX to send an SMS to a mobile phone.

To illustrate one of the countless applications:
The control of a heating system detects a fault. Via a modem and the telephone connection, the controller automatically sends an SMS and thus transmits the error message to the on-call service.

Areas of application

In a company, a modem is used which is connected to a telephone line. Via this connection the modem dials 0900 900 941 to send an SMS to a mobile phone.

Building redundancy

In spite of a failed internet connection in the event of a server or technical breakdown, an alarm can be sent simply by SMS via the redundancy. A technician can be called in for repair and thus the breakdown can be repaired promptly.

Transmit device status at low cost

A pay station in a car park no longer has 10 notes. Via a simple modem and the telephone connection, the machine sends an SMS and informs about the status. Neither an Internet connection nor additional devices and means of communication are necessary.

SMS sending without data connection

What if remote areas lack mobile phone or data connections such as ADSL? Most of the time there is a fixed telephone line. This can be used to send a status or alarm message via SMS from such locations.

eCall dialin Technology

  • Your application/device with modem supports Universal Computer Protocol (UCP)
  • Only one SMS can be sent per connection setup
  • If a message cannot be sent, it is stored temporarily for 24 hours
  • Swisscom requirement: To prevent misuse, the SMS sender is the same as your telephone number

Response times

Normally, the response time of dialin is between 2 and 5 seconds; in the worst case, 10 seconds. If there is no positive answer from dialin within the time defined in the sending device before, the call is repeated.

This leads to multiple sending of SMS messages.
This must be taken into account during on-site configuration. However, it is not possible to adjust the response time at the sending device,
