Among other things, call forwarding can be managed or phone numbers can be blocked. The Combox can be managed and SIM cards can be blocked. Access to the Swisscom Cockpit does not cause any data or roaming costs, even internationally. Detail for info and instructions Swisscom Cockpit.

SIM Card

Various SIM cards are available for terminal devices. The 3in1 SIM card is available as a physical SIM card. This means that a SIM card is sent which can be adapted to the end device by breaking it out accordingly. The 3in1 SIM cards correspond to the sizes Mini, Micro and Nano. As an electronic SIM card, there is also the so-called eSIM. This is read by a QR code in the corresponding terminal.

The cell phone and the corresponding SIM card must be protected by two different PIN codes. Subscription holders are responsible for setting up and protecting data.

Lock SIM card

If the SIM card or cell phone is lost, the SIM card must be blocked by the subscription holder as soon as possible. The blocking can be initiated independently via the Swisscom Cockpit. This is also possible in a Swisscom Shop or via ETH Zurich Fleet Management (

Replacement SIM card

A replacement SIM card or a change from physical 3in1 to electronic eSIM can be ordered by sending an email to (Be sure to specify mobile phone number)

Data packages for abroad

For data consumption abroad, it is strongly recommended to purchase data packages via Swisscom Cockpit. Data packages are released on a zone (association of different countries). This means that a released data package can not only be used in the country to which it was originally released, but can also be used in any other country that is located in the same zone. Example: If a data package was solved for Italy, this package can also be used for France since both countries are in the same zone. A data package is always valid for 365 days. Billing via the data package can only be done for business use. For private use of the data package, payment is made directly by private credit card. Information on how to buy a data package can be found in the Swisscom Cockpit manual.

Cost overview

Detailed connection statistics, as previously available in the CMN tool, will no longer be available in the future for data protection reasons. As before, the costs are automatically posted to the respective cost center/PSP-element. The SAP document contains the cost types (subscription, data pact, connections), so that the cost control can also take place in SAP as before. Upon request with justification (OTRS ticket), a detailed connection statement over a maximum of the last 6 months can be requested from ETH Zurich Fleet Management ( in exceptional cases.


The call list is available on the terminal to view the calls made or received.

Data costs

Costs for data usage can be viewed in Swisscom Cockpit.

Unlimited data volume (fair use policy), Reduction in speed from 60 GB / month

Various subscriptions include an "unlimited data volume" at maximum speed. Swisscom's "Fair Use Policy" applies to these subscriptions. This means that the provider assumes a "normal" data usage of up to 40 GB per month. The mobile connection is to be used primarily for business purposes. A "normal" private use is allowed, but the Mobile Telephony Service may not replace a private DSL Internet connection, for example. In case of excessive data usage, the provider may impose restrictions. ETH Zurich reserves the right to sporadically analyze data usage and to write to users with extremely high data usageAs of May 1, 2024, the speed will be throttled to 512 kB/s after data consumption of more than 60 GB per month. See also the provider's information letter. Users will be informed after using 48 GB and again at 54 GB and finally at 60 GB per month.
