## 购买

周期内的月度流量不会因套餐调整而产生变化\
购买任何不同于当前用户级别/系列的的套餐都视为 新购，会立即重新计算到期时间\
1、 当新旧套餐是同一系列时： 等级有效时长会自动叠加，流量会被重置。但流量重置日会变成每30天重置多次，即为您每次购买套餐的购买日，因此您不需要进行任何操作，这样的机制基本保证了双方没有损失\
2、 当新旧套餐不属于同一系列时： 等级时间会被重置，流量也会被重置，解决办法请参考：3\
3、补充:如需升级套餐(前后两次购买套餐不属于同一系列)请直接购买想要的套餐，然后建立工单我们会帮您将旧套餐的剩余价值折算到新套餐内(会有适当奖励)；

## 续费

购买和当前用户级别一致的套餐的将为 续费，会叠加到期时间

## 升级

如需升级套餐(前后两次购买套餐不属于同一系列)请直接购买想要的套餐，然后建立工单我们会帮您将旧套餐的剩余价值折算到新套餐内(会有适当奖励)；<br>
