The error is topup failed. For simba postpaid topup through qoo10, is it a must to topup on the exact day on which the plan is renewed or we need to topup 2-3 days before expiry date and then do a manual plan renew in the app.
Postpaid top up goes to a wallet. Each month, they will deduct the subscription from the wallet if there is sufficient balance, if not will charge to the linked credit card. SIMBA actually charges 5 days before the cycle date, so you need to top up at least 6 days before.
