One thought on “Follow Any of the 5 Ways to Check Balance in O2 Number!”

  1. I have just purchased a TK102B tracker for use in hiking etc.
    My o2 pay&go SIM requires checking periodically for remaining credit balance.
    As it is often remote and inside the tracker I need to call it.
    The appropriate SMS requires “carrier’s phone number and code”. I can’t find either in my searches. Can you help?
