Sunrise is Switzerland’s second-largest mobile operator, serving millions of customers across the country. In 2025, Sunrise became a standalone company after separating from UPC, and it continues to operate one of Switzerland’s strongest mobile networks. Call forwarding is included as a standard feature on all Sunrise mobile plans, from basic prepaid SIMs to the top-tier Sunrise Up subscriptions.
GSM Forwarding Codes for Sunrise
Sunrise supports the standard GSM forwarding codes used worldwide. Open your phone’s dialer and enter the code, replacing [number] with the full destination number including the country code (e.g., +41791234567 for a Swiss number).
| Forwarding Type | Activate | Deactivate | Check |
|---|---|---|---|
| All calls | **21*[number]# | ##21# | *#21# |
| No answer | **61*[number]**[seconds]# | ##61# | *#61# |
| Busy | **67*[number]# | ##67# | *#67# |
| Unreachable | **62*[number]# | ##62# | *#62# |
| Cancel all | ##002# |
Replace [seconds] with the ring time before forwarding kicks in: 5, 10, 15, 20, 25, or 30 seconds. 20 seconds is a solid default.
Example: Forward unanswered calls after 20 seconds to +41791234567:
**61*+41791234567**20#Our interactive forwarding tool generates the correct code for your specific setup.
Setup via the My Sunrise App
The My Sunrise app (available for iOS and Android) gives you a visual interface for managing your Sunrise subscription, including call forwarding.
- Open the My Sunrise app and log in with your Sunrise account
- Select your mobile subscription
- Navigate to Services or Call settings
- Find Call forwarding (Rufumleitung / Renvoi d’appels)
- Choose the forwarding type (all calls, no answer, busy, unreachable)
- Enter the destination number and save
The app updates your forwarding settings right away and shows the current configuration so you can confirm everything is correct.
Setup via the Sunrise Online Portal
Sunrise’s web-based customer portal provides the same management options:
- Log in at sunrise.ch with your My Sunrise account
- Select your mobile subscription
- Navigate to call services or forwarding settings
- Configure your rules and confirm
The online portal works well if you’re setting things up from a computer or managing multiple Sunrise subscriptions.
Sunrise Customer Service
Call 0800 707 707 from any Swiss phone (free) or +41 58 777 07 07 from abroad. Sunrise’s support team can help you set up, modify, or troubleshoot call forwarding over the phone.
Sunrise Plan Details
Sunrise offers several plan families. Here’s how forwarding fits into each:
- Sunrise Up S/M/L/XL: These contract plans include unlimited domestic calls. Forwarded calls within Switzerland are covered by your plan. Forwarding to international numbers costs extra.
- Sunrise Prepaid: All GSM forwarding codes work on prepaid. Each forwarded call is charged at the standard per-minute rate from your credit balance.
- Sunrise We plans (multi-line): Each line in a Sunrise We family plan has its own forwarding configuration. Set up forwarding separately for each number.
- Sunrise Business: Business plans support the same GSM codes and offer additional management through the Sunrise Business portal.
Things to Watch Out For
- Switzerland and the EU: Switzerland is not an EU member, so EU roaming regulations don’t apply by default. If you’re traveling to an EU country, check your Sunrise plan’s roaming terms. Forwarding while roaming outside Switzerland may incur extra costs.
- International forwarding costs: Forwarding calls to a number outside Switzerland (e.g., Germany, Austria) counts as an international call from your Sunrise number. Check your plan’s international rates.
- Combox voicemail: Sunrise’s voicemail service is called Combox. Setting up no-answer forwarding overrides the Combox configuration. If you want Combox back, you’ll need to remove your custom forwarding and reactivate Combox through the My Sunrise app.
- Multilingual interface: Sunrise serves customers in German, French, Italian, and English. Menu labels in the app and portal will match your language preference.
Troubleshooting
- GSM code returns an error: Double-check the destination number format. Include the country code (+41 for Switzerland). Also verify that your Sunrise plan supports forwarding.
- Calls go to Combox instead of your forwarding destination: Combox may have a shorter timeout. Deactivate Combox through the My Sunrise app, or contact Sunrise support to adjust the voicemail delay.
- Forwarding doesn’t work after setting it up: Dial
*#61#(for no-answer),*#67#(for busy), or*#62#(for unreachable) to check whether the correct destination is configured. If it shows nothing, re-enter the GSM code. - Ring time seems wrong: The seconds value you set in the GSM code is approximate. Network processing can add a second or two to the actual ring time.

**62*[your Safina number]#Safina answers the call, talks to the caller, and sends you a notification with a summary of the conversation. Visit the setup guide to get your Safina number, or use the interactive tool to generate the codes.
