Drei (also known as “3” or Hutchison Drei Austria) is one of Austria’s three major mobile operators, alongside A1 and Magenta. The network covers over 98% of the Austrian population and supports all standard GSM forwarding codes. Whether you’re on a Drei contract or a Drei Wertkarte (prepaid), call forwarding works the same way.
GSM Forwarding Codes for Drei
Drei uses the standard GSM codes that work across all mobile carriers. Open your phone’s dialer and enter the code, replacing [number] with the full destination number including the country code (e.g., +431234567890 for an Austrian 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: 5, 10, 15, 20, 25, or 30 seconds. 20 seconds gives you enough time to reach your phone without keeping the caller waiting too long.
Example: Forward unanswered calls after 20 seconds to +431234567890:
**61*+431234567890**20#

Setup via the Drei App (Mein Drei)
The Drei App, also called Mein Drei (available for iOS and Android), provides a visual way to manage your mobile services, including call forwarding.
- Open the Drei App (or Mein Drei) and log in with your Drei credentials
- Navigate to Services or Einstellungen (Settings)
- Find the Call forwarding or Rufumleitung section
- Select the forwarding type you want to configure
- Enter the destination number and save
The app shows your current forwarding configuration, so you can quickly check whether forwarding is active and where calls are being sent.
Setup via the Drei Kundenzone Portal
Drei’s web portal offers an alternative way to manage forwarding from a computer:
- Log in at drei.at with your Mein Drei account
- Navigate to your mobile service settings
- Find the call forwarding or services section
- Configure your forwarding rules and save
The Kundenzone is particularly handy if you manage multiple Drei numbers or prefer a larger screen for configuration.
Drei Customer Service
For phone support, dial 660 30 30 from your Drei mobile (free of charge) or 0660 30 30 from any Austrian landline. Drei’s support team can activate, modify, or troubleshoot forwarding for you.
Things to Watch Out For
- Forwarding costs: On Drei contract plans, forwarded calls typically use your included minutes. When you exceed your allowance, standard overage rates apply. On Drei Wertkarte (prepaid), each forwarded call is deducted from your credit at the normal per-minute rate.
- International forwarding: You can forward calls to numbers outside Austria. The forwarded call is billed as an international call based on your tariff. If your plan includes international minutes, those may apply.
- EU roaming: Within the EU, call forwarding works under the EU roaming regulation. Outside the EU, availability and costs depend on your specific tariff and the country you’re visiting.
- Drei voicemail: If you have Drei’s voicemail service active, setting custom forwarding rules for no-answer may override the voicemail destination. After setting up forwarding, dial
*#61#to verify the destination is correct. - Drei Business customers: Business tariffs from Drei also support GSM forwarding codes. The Kundenzone for business accounts has a separate login at business.drei.at.
Troubleshooting
- GSM code returns an error: Confirm the destination number includes the country code (e.g., +43 for Austria). Also check that your plan supports call forwarding, as some very basic prepaid plans may restrict it.
- Calls still go to Drei voicemail: The voicemail may have a shorter timeout than your forwarding delay. Contact Drei support at 660 30 30 to adjust the voicemail timeout, or set a shorter delay in your GSM code.
- Forwarding doesn’t work abroad: Some roaming destinations don’t support all GSM code types. Try setting up forwarding before traveling, or contact Drei support for help.
Using Safina with Drei
Safina works with Drei just like with any other Austrian carrier. Set up conditional forwarding so your phone rings first, and Safina steps in only when you’re unavailable:
**61*[your Safina number]**20#
**67*[your Safina number]#
**62*[your Safina number]#
After each call Safina handles, you receive a notification with a summary of what the caller wanted. Check the setup guide to get your Safina number.
