My prepaid account is expired 5 days. Today I want to renew my account and I found my balance became 0. (I have $8 balance before). Is that because my prepaid account expired so make my balance become 0?
The system likely saw the $8 and tried to apply it toward a baseplan. This is assuming that you signed up for automatic top up. Since the funds were not enough to cover the amount of the baseplan, you'll see a balance of $0. If for example, you apply funds for a $25 baseplan, you should see a credit of $8 on your account.
