Certain phone calls says balance too low

Most likely the numbers are non US and require a per minute charge.  

Same issue here. The problem number is a NY area code and I'm calling from a NY area code. I've seen a lot of people with the same issue, but no solution.

I'm not sure you read my post. My balance isn't the issue. 

We appreciate your response @fzfrank

To gather a better understanding of the specific NY area code you're trying to call, we'd like to know more:

• Is the particular number associated with the contact list on your cellphone?
• If not, is it a 1800 number or a number to a business or company?
• Are you able to make calls to other numbers besides the main number you're having problems with?

Provide us more specific details to help determine the cause. 

Thank you.
