To prevent your credits or packages from expiring, please load your account within nine (9) months of your last credit reload.
To check your Billing History to confirm the last reload on your account:
Go to the KnowRoaming App > Select More > Payment & Billing > Billing History > Select desired month
All prepaid credit and unused data packages will expire nine (9) months after the last prepaid credit purchase, unless otherwise stated. Any prepaid credit balance and unused data packages remaining in the account will expire if the customer does not make another prepaid credit purchase for a period of nine months. KnowRoaming allows a grace period of seven calendar days following the credit expiration date in order to purchase more credit and retain the prepaid balance and unused data packages.
