A smart way to identify yourself
Having multiple numbers on your SIM could be confusing; Smart Caller ID (CLI) means it never is.
When you make a call, the person you are calling sees the incoming call as being from the best number for them to call you back on.
For example a US person would see your US number, and a UK person would see your UK number.

It doesn't matter how many numbers you have on your SIM. Tru will seamlessly identify the most appropriate one to display based on the number you are calling.
