Mobile Telephony - General information
Introduction
Mobile Telephony is an additional service of ETH Zurich for mobile telephony and is based on the Swisscom Mobile Network. Administration is handled exclusively by the ID Infrastructure Section.

Subscriptions
The Mobile Telephony Service offers various types of subscriptions. A basic distinction is made between voice (voice and data) and data-only subscriptions. The individual subscriptions are described in the “Rate Overview” document (requires an ETH Zurich login). The costs incurred for the Mobile Telephony subscription are borne by the respective units. For central administrative bodies, a cost limit of CHF 30.– per month applies. Higher costs may be passed on to employees. Budget managers are responsible for financing and cost monitoring. Please note that no device subsidies are offered, and therefore no discounted devices can be obtained through the subscription. Subscriptions cannot be ordered or canceled on behalf of other individuals.

New Phone Number
When ordering a subscription with a new phone number, Swisscom automatically assigns a random phone number. This number cannot be changed later.
Transferring a Personal Phone Number to ETH Zurich
Only personal phone numbers under contract with Swisscom can be transferred via the IT Shop.
Personal phone numbers under contract with a third-party provider must first be ported to Swisscom by the subscriber themselves. To port a phone number from a third-party provider to Swisscom, use the Swisscom Authorization Form for Mobile Number Porting (DE). This form can be used to initiate the porting process at a Swisscom store.

Phone Number Assignment (Transfer of Phone Numbers to Employees)
A mobile phone number can be assigned by ETH Zurich for personal or business use. The assignment of a phone number must be initiated by ETH Zurich. Porting the number to a third-party provider (Sunrise, Salt, Wingo, M-Budget, etc.) is only possible after the number has been assigned to Swisscom. Business assignments must always be initiated by emailing cmn@id.ethz.ch.
ETH Zurich affiliates can request a personal number assignment via the IT-Shop (requires an ETH Zurich login). Organizations affiliated with ETH Zurich (ETH Board, ASVZ) do not have access to the IT-Shop and must therefore request a personal number assignment by emailing cmn@id.ethz.ch.
The following information is required for this process.

Takeover confirmation
As confirmation, Swisscom sends an email or text message directly to the person who initiated the request. The transfer must be confirmed by the subscription holder. The subscriber must then verify their identity. If the phone number transfer is not confirmed within 3 days of the cancellation date, the subscription will be automatically suspended and deactivated, and can no longer be used. Responsibility for the initiated phone number transfer lies with the employee. Reactivation is not possible if the transfer is not confirmed.
Online identification
Swisscom provides detailed instructions for transferring a phone number and for online identification. The document “Swisscom Instructions for Transferring a Phone Number to a Private Line” describes the process step by step. Please note that screen mirroring is turned off on the mobile camera.
Cancellation
ETHZ members can request the cancellation of a mobile phone subscription through the IT Shop. These requests are processed immediately. Members of ETHZ-affiliated organizations (ETH Board, ASVZ) do not have access to the IT Shop and must submit their cancellation request via email to cmn@id.ethz.ch. The following information is required for this purpose.
Continuation of the call number:

- Swisscom prepaid or all third-party providers: When changing to prepaid or to an other provider, the identification must always be done in a Swisscom Shop. Porting to a provider can then be initiated.
- In case of takeover by the future employer, the phone number will be released by ETH Zurich for takeover. The company that takes over the number can then initiate the direct takeover. In addition, the future employer must specify the company ETH Zurich at the time of the takeover so that the takeover works.

A suspended subscription can be reactivated. If necessary, an APN (data subscription) must then be reactivated via ETH Zurich fleet management. After 365 days a suspended subscription will automatically be reactivated. Short suspensions (2-3 months) are often not worthwhile. Tip: Leave the subscription activated or cancel it and reorder it if necessary.
Cost center
The monthly costs incurred per subscription are transferred internally via SAP posting either to a cost center or a PSP-element. The correct and current specification of the cost center is the responsibility of the subscription user. The cost center can be adjusted personally at any time via the IT Shop (requires ETH Zurich login). The billing will be made to the cost center or PSP-element stored at the end of the month.
Multi Device
A Multi Device SIM card is an additional SIM card, for example a tablet, smart watch, router, etc. and can be ordered as an option to an existing Voice Mobile Telephony subscription. Additional multi-device cards cannot be ordered for data subscriptions. The Multi Device SIM card is available as an eSIM or as a physical 3in1 SIM card. An additional Multi Device SIM card can be ordered by sending a ticket by mail to cmn@id.ethz.ch. (Please indicate alwaxs your mobile phone number on any Ticket)
Upgrade subscription
An upgrade of a subscription requires the approval of the cost center manager. The order can be entered in the IT Shop and must then be approved in ethis by the cost center manager.

A new activation code for already existing subscriptions (no new subscription orders) can be requested via the IT Shop (requires ETH Zurich login). An e-mail will be sent with the order, with which a QR code can be called up. The link on the mail is valid for 120 hours. After calling the link for the first time, the QR code is valid for another 60 minutes.
Settings
Swisscom Cockpit
Swisscom's end-user self-service portal for mobile devices is called Swisscom Cockpit.
It is possible to manage settings for roaming, data packages, cost limits, etc.. But also various information about the subscription, the devices or the costs can be viewed. 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 (cmn@id.ethz.ch).
Replacement SIM card
A replacement SIM card or a change from physical 3in1 to electronic eSIM can be ordered by sending an email to cmn@id.ethz.ch. (Be sure to specify mobile phone number)
Shipping
Physical SIM cards are shipped directly from Swisscom to the official office address.
Calling in and to other countries
Calling in and to other countries
The standard subscription at ETH Zurich is the Natel go Swiss Premium and includes calls in Switzerland (free of charge). Calls to foreign countries are charged. Calls from foreign countries to Switzerland and even further abroad are charged.
With an international subscription such as Neighbour or Europe etc., calls to the relevant zone are included. Calls from this zone to Switzerland or to another country within this zone are also included (free of charge). Calls from outside this zone or calls to another zone are charged.
International data packages
For data traffic in other countries, we strongly recommend purchasing data packages via Swisscom Cockpit. Data packages are purchased for a zone (network of different countries). This means that a purchased data package can be used in all countries in the same zone. Example: If a data package has been purchased for Italy, this package can also be used for France because both countries are in the same zone.
An international data package is valid for 365 days. However, a data package for Switzerland is valid for 1 month.
Billing via the ETHZ subscription is only possible for business use. For private use of the data packages, payment is made directly by private credit card. Information on purchasing a data package can be found in the Swisscom Cockpit instructions.
International zones
Swisscom distinguishes between different tariff zones.
| Zone | Abo Typ |
|---|---|
| Schweiz, FL | Swiss |
| Europe, UK | Neighbours, oder Europe |
| Welt 1 | Global |
| Welt 2 | - |
| Rest der Welt | - |
*Global does not automatically mean worldwide data or telephony included. Global means countries which are assigned to the World 1 zone. There are also countries which are assigned to World 2, Rest of the World or no zone at all.
Tip: In the Swisscom Cockpit, you can click on the plus sign under Packages and select the relevant country. The corresponding zone and tariffs are then displayed automatically.
More information can be found on the corresponding Swisscom page.
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 (cmn@id.ethz.ch) in exceptional cases.
Conversations
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. As of May 1, 2024, the speed will be throttled to 1 Mb/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.
Support
The Service Desk or the Smart Desk are generally available for support.
In addition, ETH Zurich Fleet Management can be contacted at cmn@id.ethz.ch.
