Hi barbie! Welcome to Globe Community!
Your Prepaid SIM has already expired. You may purchase a new SIM at any Globe Store or authorized dealers. To keep your new SIM active, just regularly reload your account within the load validity period so you can enjoy Globe/TM services. Thank you!
Also, Globe Community is for non-account related concerns. For any account-related concerns like this, you can raise it to our Twitter Specialists at http://www.twitter.com/talk2GLOBE or any of our support channels listed at Contact Us so they can help you isolate the issue, and if there's a need to make any necessary load reversals.
