eCall Dialin – Formerly SMS Single Account from Swisscom

Since 1 February 2013, Dolphin Systems AG (since 1.10.2019 F24 Schweiz AG) has been operating Swisscom’s former “SMS Single Account” service.

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 as of 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 to learn more about SMS, fax and business messaging.

However, access to this service will continue to be guaranteed via the existing number 0900 900 941 (CHF 0.39/minute). You can find out more under “Switching from 079 to 0900”.

Do you want to send an SMS message without a data connection and inform about the status of a device, for example?

Simply send an SMS directly from your application or from your sensor/device via modem.

Important to know about eCall dialin:

  • The dial-in number 079 xxx xx xx will no longer work by the end of 2015

  • Circulation Swisscom: To prevent misuse, the SMS sender is the same as the number of your telephone connection.
  • Only one SMS can be sent per connection setup.

Change from 079 499 XX XX to 0900 900 941

Swisscom has discontinued the service

In 2015, Swisscom discontinued 079 access. Not affected by this is the number 0900 900 941, which we have also taken over from Swisscom.

Example

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

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

Areas of application

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

Further application examples for eCall dialin

Build redundancy

Despite a failed internet connection in case of a server or technical breakdown, it is easy to be alerted by SMS via the redundancy. A technician can be called out for the repair and thus the breakdown can be repaired promptly.

Cost-effective transmission of device status

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

Sending SMS without data connection

What if remote areas lack mobile phone or data connections such as ADSL? Most of the time there is a landline. A status or alarm message can be sent 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 temporarily stored for 24 hours
  • Swisscom’s version: To prevent misuse, the SMS sender is the same as the number of your telephone connection

Response times

Normally the response time of dialin is between 2 to 5 seconds; in the worst case 10 seconds. If there is no positive answer from dialin within the time predefined in the sending device, the call is repeated. This leads to multiple SMS messages being sent.

This must be taken into account when configuring the system on site. However, the response time cannot be adjusted at the sending device we can parameterise this in dialin for a specific number. However, this assumes that no acknowledgement of receipt from the SMS-C centre is required. If this is desired, please call us so that we can adjust the configuration in dailin for you.
