When you activate your Smart SIM, you'll notice it has a US +1 number assigned to it. This is completely normal and nothing to worry about.
Why does it have a US number?
When you activate your Smart SIM, it’s automatically set up with a US phone number. This is purely a part of the setup process and isn't usable.
Can I use it to make calls or send texts?
No, the number is not usable for calls or messages. It's there purely as a reference and won't interfere with your main SIM or your normal service in any way.
Does it affect how Smart SIM works?
Not at all. Your Smart SIM works exactly as intended: free roaming in 180+ countries and data on supported apps, regardless of the US number.
