Your Pay As You Go SIM plan will last for 30 days or until you’ve used up all your allowances. You can always check how many days are remaining or how much data you have left by visiting the iD Mobile appor My Account online.

Hi ​@nannyhilda 

This is just the length of time that the bundles last (or until allowances are exhausted), once a bundle has expired or exhausted, you’ll want to consider a new one.

Thanks for the help here ​@MZone.
