Your Mini Mega Plan may have expired if you have not added another Plan value on or within the 30-day expiry period. Unfortunately you may lose access to your current number, and will need to get a new SIM.
Note: Minimum amount to keep using the Mini Mega Plan is $24.90 for 30-days access. Lebara recharge values ($9.90/$19.90) can only be used to top up or add credit amounts.
