Just like all other financial services, it's important to have at least one bank account linked with line at all times. You can fund your lucky tickets and also track your budgets, and transactions.
A. Non-subscribed users
If you've not yet subscribed for a line and you have linked only one account, then you can only remove it after adding another bank account. This way you will not face any service interruption.
B. Subscribed users
If you've already qualified for a line and have subscribed, you can not remove the account you had used for your line qualification.
However, if this account is no longer in use or you wish to pay your dues from a different account/card, you can do easily do that. You can log in to the app and clear your remaining dues.
Alternatively, you'll receive reminder emails 3 days before the due date to pay your dues. You can pay via any method such as debit card, credit card, apple pay, google pay, etc.
