Portability guide

Changing operators in Switzerland while keeping your number: portability explained

Number portability is a right in Switzerland. Here's how to transfer your +41 number to a cheaper plan, without interruption and without losing it.

The answer in one sentence

To keep your Swiss number when changing operators, do not cancel anything yourself: choose your new plan, and the portability request — offered free of charge by ATELCO MOBILE — automatically triggers the transfer and termination of the old contract.

Choose your new plan

Select the offer that suits your usage. Number portability is free at ATELCO MOBILE: no fees to keep your number.

A consultant prepares the transfer

We collect the necessary information (line holder, current operator) and initiate the portability request for you.

Do not cancel yourself

This is the classic mistake: if you cancel before the transfer, you could lose your number. Portability automatically triggers the cancellation of the old contract.

Your number switches over

On the agreed date, your +41 number will switch to the new network. You insert the new SIM or eSIM and remain reachable as before.

Frequently asked questions about portability in Switzerland

Can you keep your number when changing operators in Switzerland?+

Yes. Number portability is a right in Switzerland, regulated by OFCOM (regulations RS 784.101.113/1.10, version in force since 01.03.2024). Your new operator handles the transfer: you keep your +41 number without service interruption.

How much does it cost to port a Swiss number?+

At ATELCO MOBILE, portability is free: we charge no fees to transfer your number to one of our partner operators.

How long does the number transfer take?+

Typically, allow a few working days between the request and the actual switch. The consultant will give you a precise date, and you will remain reachable on your old line until the transfer.

What happens if I'm still under contract?+

If your current contract has an unexpired minimum term, your old operator may charge the remaining monthly fees. We check your situation before initiating portability to avoid any surprises.

Do I have to cancel my old subscription before portability?+

No, absolutely not. The portability request automatically triggers the cancellation of the old contract. If you cancel yourself beforehand, you risk permanently losing your number.

Can I transfer a prepaid number?+

Yes, a prepaid number can also be transferred to a subscription. However, the remaining balance on the prepaid card will not be transferred: use it before the switch.
