You can cancel through your Lebara customer account or customer service. To keep your number, register the port with the new provider.
Price change at this provider: our report →Number portability is free in Switzerland and usually takes 1 to 3 working days. Important: do not cancel yourself if you want to keep your number. Register the port with the new provider, who handles the cancellation. Anyone who cancels first loses the number.
These providers run on the same network but cost less. Coverage and 5G are identical, and the order follows price alone.
