DIALING RULES
Follow these rules to ensure your call connects successfully and charges correctly.
Switzerland requires the 00 prefix for all international calls. Do not use + or any other format when dialing from a Swiss landline or traditional phone.
Portuguese local numbers are always 9 digits long. Do not drop the leading digit or area code when calling internationally.
When you see a Portuguese number written with a leading 0, drop it. The leading 0 is only used for domestic calls within Portugal. For international calls, use the 9-digit number without the leading 0.
Calls to Portuguese mobiles (91–99 prefixes) may be charged at the mobile rate. Confirm your call type before dialing to understand the expected charge.
BEST TIMES TO CALL
Maximize connection quality and respect business hours with these timing guidelines.

TROUBLESHOOTING
Resolve common calling issues and understand any limitations when calling Portugal from Switzerland.
If the line cuts out, try calling again using the same number. Check your internet or phone signal if using a data-based service. Network congestion during peak hours (17:00–20:00 Switzerland time) may occasionally affect call quality.
Verify you've entered exactly 9 digits for the Portuguese number, with no leading 0. If you copied a Portuguese number from a website or directory and it shows a leading 0, remove it before dialing.
Some special numbers (emergency services, toll-free, or premium numbers) may not connect from abroad or may incur additional charges. Stick to regular landlines and mobile numbers for standard calling.
Always double-check the number before dialing. Portuguese phone books and official directories (e.g., CTT postal service) can help verify numbers. If you reach a wrong number, politely disconnect and re-verify the digits.
