The short answer is yes! Your ONSIM service is fully capable of receiving calls from anywhere in the world. Whether it’s a business partner in New York or a family member in Tokyo, your number remains globally reachable.
To help you understand how this works—and how it affects your billing—here is a quick breakdown:
1. Global Reachability
There are no geographic restrictions on incoming calls. As long as the person calling you has the ability to dial a UK number, they can reach you.
2. Is it Free to Receive?
For the vast majority of users, receiving an international call is completely free.
If you are in the UK: You do not pay to receive international calls.
If you are Roaming: Depending on your specific plan, receiving a call while physically located abroad may incur roaming charges. Always check your roaming "Zone" before traveling.
3. Outbound vs. Inbound
It is important to distinguish between receiving and making calls:
Receiving: Open to all international numbers.
Making: Outbound international calling is restricted by default to prevent accidental charges. If you need to make International calls, see our guide here.
