How do I configure my mobile phone for mobile data use abroad?

To be able to use data services abroad, your mobile phone must be correctly configured.

So that we can offer you a perfect roaming experience, we work together with our roaming partner Proximus. For this reason, it may be the case when you are abroad that your mobile phone either displays the settings of our roaming partner (e.g. in the APN list) or asks you to select a mobile provider. In the second case, simply select our roaming partner Proximus. In all other cases, it should not be necessary to change any further settings so that you can use your mobile phone abroad.

For information on how to configure other mobile phones, please consult the manufacturer’s instruction manual. In doing so, use the parameters listed below to configure a so-called APN (Access Point Name). You will need this for roaming.

Parameters for data use abroad:


upcnet roaming


MCC (if required):


MNC (if required):


This APN setting is not visible while in Switzerland and therefore disappears when saved. Once you are abroad the APN setting will reappear, allowing you to manually activate it if necessary. If you have already configured an APN yourself in the past, you may need to do this again after 1 November 2015. Use the settings provided above for this.

Important: To be able to use data services abroad, the data roaming option in your mobile phone menu must be activated.

What do I need to do to use my mobile phone abroad (roaming)?

To use your mobile subscription abroad, you do not need to do anything. Your mobile subscription is available to you abroad as it would be in Switzerland. However, it might be worthwhile having a look at the question “How do I configure my mobile phone for mobile data use abroad?” for more information on using mobile data while being abroad.

It should be noted that the use of the international dialing code is required to make calls while being abroad, apart from calls to Switzerland. For example, while being abroad and calling the German number 0xxxx xxxxxx, you should use the international dialing code +49 without the leading zero of the number: +49 xxxx xxxxxx.

The costs to use your subscription abroad are generally much higher than the cost of using it in Switzerland. By default, you will be automatically informed via SMS about the costs once your mobile phone connects to a foreign mobile network.

So that we can offer you a perfect roaming experience, we work together with our roaming partner Proximus. For this reason, it may be the case when you are abroad that your mobile phone either displays the settings of our roaming partner (e.g. in the APN list) or asks you to select a mobile provider. In the second case, simply select our roaming partner Proximus. In all other cases, it should not be necessary to change any further settings so that you can use your mobile phone abroad.

Call number porting

How can I keep my mobile number?

If you wish to retain your current mobile number from your current mobile telephony provider, please indicate this when ordering the UPC mobile subscription. We will process your request free of charge. The number portability procedure depends on whether you have a post-paid or prepaid mobile subscription with your current mobile telephony provider.


  • - If you currently have a post-paid mobile subscription, you will receive a number portability form (POA). Please return the signed form to the address indicated on the form. Once your request has been approved, your mobile number will be transferred to UPC. Please observe the period of notice stipulated by your current provider to avoid any additional costs.


  • - If you currently have a prepaid mobile subscription, you can indicate your change of provider by sending an SMS with the word “Yes” (without quotation marks) to the shortcode 499. You will then receive a confirmation SMS.

  • - Please note that you may lose any prepaid credits still available as soon as your mobile number is transferred to UPC. We therefore advise you to use your prepaid credits still available before your mobile number is transferred.

If you already have a mobile subscription with UPC and did not indicate when ordering that you wanted to retain your previous mobile number from your current mobile telephony provider, you can nevertheless submit your request to us afterwards. To do so, please contact customer service.

As soon as your current provider has confirmed the porting of your current phone number, you will receive an SMS with the exact porting date. This SMS will be sent to you on your current mobile number with your current mobile telephony provider.

Should your request be refused, you will automatically be informed by letter and we will send you the necessary instructions to solve the problem.

Mobile network

Do I need to set up my phone again, e.g. mailbox?

No, all settings saved on your mobile phone will be kept.

Do I now need a new subscription?

No, your existing subscription from UPC Business including any options will remain valid on the same terms. You can continue to use your telephone as normal.

How can I see which network I am using?

You will not see any change. Since you are still a UPC Business customer, the network name displayed on your mobile phone is still “upc ch”.

What changes will there be for me?

There will be no impact for you, apart from the fact that you will be connected to the Swisscom network after the switchover.

What do I need to do if I can no longer make calls or browse the web?

Please contact our Support Team on +41 800 858 575.

What will happen on the 2nd of April 2019?

Since the 8th of January 2019 UPC Mobile customers had the opportunity to connect to both networks Swisscom and Salt (previous network), with Swisscom being the preferred network. Starting from the 2ndof April 2019, the Salt network will not be accessible anymore.

What does that mean?

The majority of UPC Mobile customers will not be affected by this operation since they are already using the Swisscom network. However, customers having selected the Salt network manually on their device will no longer have any mobile services from the 2ndof April 2019.

What shall I do?

  • * If your «network selection» is set on «automatic» on your mobile device, you don’t need to do anything.

  • * If your «network selection» is set on «manual», please follow below instructions while you are in Switzerland:

    • - Go to «manual network selection»

    • - Look at the list of possible networks

    • - If you see «Salt» and «upc ch», select «upc ch»

    • - If you see «Swisscom» and «upc ch», select Swisscom

This step assures that you are migrated successfully to the new network and that there is no loss of mobile services.

In case of questions please contact our customer service on the free number +41 800 858 575.

Will Wi-Fi Calling still be offered?
