Even abroad you are always reachable under your mobile number. You can call, send SMS and surf the Internet as usual.
If you are abroad, you can make phone calls, send SMS and go online as usual. If you want to use data roaming (e. g. for surfing the Internet), check your smartphone settings if data roaming is switched on.
You can also use your prepaid mobile phone to make calls, send SMS messages and surf the Internet in most countries. Rates vary by country. We recommend that you check them before you leave for your trip:
With the inOne mobile basic, go and premium subscriptions for private and business customers, there are no limits on your communication while travelling.
Unlimited Internet, telephony and SMS/MMS are included in the EU/Western Europe, USA and Canada. Once you have exceeded the 100 GB surfing allowance, speed is reduced to 128 kbit/s.
In countries within the World 1 zone, the surfing allowance is 10 GB per month. Unlimited telephony and SMS/MMS are included.
In all other countries, the monthly allowance is 1 GB surfing, 30 minutes’ telephony and 1,000 SMS. When you have used up your data allowance, we recommend purchasing a data package.
If you regularly make calls from Switzerland to other countries, it is worth adding the International Calls option, unless you have inOne mobile premium, which already includes calls from Switzerland to the EU/Western Europe and the USA/Canada. If you regularly make calls from Switzerland to other countries, it is worth adding the International Calls option.
Residential customers with inOne mobile XS-XL or NATEL infinity 2.0 subscriptions and SME customers with inOne SME mobile XS-XL or NATEL® infinity 2.0 business subscriptions have a certain number of days included in their mobile subscription. During those days they can use the Internet, make phone calls and send SMS messages in the EU/Western Europe at no additional cost.
If you have an inOne (SME) mobile M subscription, you can write SMS, make phone calls and surf for 6GB during 60 days in the EU/Western Europe at no extra cost. If you use your roaming days and 6GB data allowance at different speeds, one of the following can happen:
The roaming days cannot be used outside the EU/Western Europe. If you have an inOne (SME) mobile XS - L subscription, you have 1000 SMS/MMS per month and 100MB per year included in your subscription. If you want to use the internet or make phone calls outside Europe, we recommend that you buy a data package and/or use the Travel Voice Option for cheaper phone calls.
Close to the Swiss border, your mobile phone may automatically connect to the mobile phone network from a neighbouring country – for example the German “Deutsche Telekom” or Austrian “A1”.
Unnoticed, this automatic carrier switch can generate unnecessary roaming charges.
Therefore, we recommend that you switch off the automatic network selection in the Swiss border area.
You can check your current usage for surfing abroad at any time via the Swisscom Cockpit. The current usage for phone calls and messages are shown in the Customer Center with a delay.
COMBOX® message within Europe is always free for inOne mobile customers.
Listening to the COMBOX (+86) within the roaming days is free of charge. After this, listening to the messages will be charged according to the standard tariffs. Prepaid and inOne mobile light customers will be charged in any event.
If you use your COMBOX® outside of Europe, increased costs may be incurred or roaming days may be charged: If you do not accept a call and the COMBOX® switches on, an incoming connection and an outgoing connection (for accepting the call through COMBOX®) will be charged.
That is why we recommend switching off call forwarding on your COMBOX® while travelling:
Roaming means that you use another provider's network when you are abroad - for example, you are a Swisscom customer and use Orange's network during your holiday in France.
The foreign telecoms providers charge Swisscom for calls made, SMS messages sent and kilobytes surfed on their networks. This is a service that Swisscom has to buy and for which there are currently over 600 contracts.
If you don't (or can no longer) access the Internet abroad, try the following:
If the Internet still does not work, please do the following:
The base rate should be deactivated by default, as surfing with the base rate can quickly lead to higher costs.
You can enjoy the lowest-cost surfing by switching to an inOne (SME) mobile subscription. With the inOne (SME) mobile go and premium subscriptions, you can enjoy unlimited surfing within the EU/Western Europe.
You can enjoy the lowest call costs by switching to an inOne (SME) mobile subscription. With the inOne (SME) mobile basic, go and premium subscriptions, you can enjoy unlimited calls and SMS within EU/Western Europe.
Outside Europe, we recommend the Travel Voice Option (for private and SME clients), which pays off if you don't make many phone calls.
With the Travel Voice 30 days option for SME clients you can call and send messages cheaper for 30 days worldwide.
The inOne (SME) mobile basic, go and pro subscriptions include unlimited SMS within the EU/Western Europe. During the roaming days, customers with an inOne (SME) mobile XS-XL and NATEL® infinity (business) subscription can send unlimited free SMS messages within Europe.
Outside of Europe, customers with an inOne (SME) mobile XS subscription (or higher) enjoy 1000 SMS per month included.
Note that SMS are charged per 160 characters. For example, if an SMS has of 200 characters it is charged as two SMS. By using special characters and other alphabets, the number of characters calculated may differ from the number of characters displayed on the phone. When sending smileys, images, GIFs, stickers etc., the SMS turns into an MMS.
Charges for MMS by price plan. To the tariff query.
If you are near the border, it is possible that your mobile phone may connect to a foreign mobile network – for example if there is poor or no reception on the Swisscom network. This can also happen if foreign networks are available further away from the border, for example in the Lake Geneva region and the mountains close to the border (Jura, Alpstein, Graubünden or Valais Alps, etc.).
Since much lower radiation limits apply in Switzerland than in the EU, foreign networks reach much further into Switzerland than vice versa.
To avoid roaming charges we recommend that you switch off the automatic network selection.
