MTN eSIM有足够余额，但是订购KMN一直提示“Activation of Keep My Number three years failed due to insufficient balance.”

给号码充值2000NGN后，App 显示金额已经到账，但在拨打 *365*3# 订购 KMN 服务时却一直收到以下提示：
Activation of Keep My Number three years failed due to insufficient balance. Click https://mtnapp.page.link/myMTNNGApp to recharge, dial *671# to buy airtime from MoMo wallet, *904# to recharge from your bank account or *303# to borrow airtime & pay later.

经过两小时的反复尝试，我终于想到了解决办法：

打开并关闭飞行模式

秒成功！

啥解决办法？我充值成功好像给退款了
