How do I dial an international number with +1?
On mobiles you can usually dial “+1” followed by the national number. On landlines you may need to dial your country’s exit code first, then 1, then the national number (often with any domestic trunk prefix removed).
Why can +1 be ambiguous?
Some calling codes are shared (for example, +1 is used across the North American Numbering Plan). If a calling code is shared, you need additional digits (area code/number ranges) to identify the exact destination.
