Hi are you able to help as I have had my number and account for 20 years and I have tried to make a call from my mobile and get a recording saying I have insufficient funds to make a call??
Welcome to the Community!
We'd like to check your account for better understanding of the situation.
Please send me a PM with your customer ID or mobile number to assist you accordingly.
Also, please make sure that you have sufficient funds or a prepaid balance if your plan doesn't come with an unlimited phone calls/SMS.
