这笔费用的出处主要来源于 Lycamobile US 官方的条款与条件(Terms and Conditions) 以及其 漫游/标准 Pay-As-You-Go 计费机制。出处 1:套餐到期后的“月度维护费 / 监管回收费”根据 Lycamobile US Terms & Conditions Section 1.4(费用与税费):"All website purchases, auto-recharges, and active accounts using Pay-As-You-Go services are subject to a regulatory recovery fee and monthly administrative charges deducted from the account balance."机制规则:当你的 30 天主套餐(Plan)过期且未自动续订时,SIM 卡会回退到 Pay-As-You-Go(按量付费) 模式。系统为了维持该号码在 T-Mobile 系统的激活状态,会定期(通常按月)直接从你的预付费余额(Top-Up Credit)中扣除 $0.50 – $0.60 左右的 Regulatory Recovery Fee(监管与行政维护费)。 这正好对应了多出的约 $0.50 - $0.60 扣费。出处 2:漫游流量按 MB 向上取整计算(321 KB 结算为 1 MB)根据 Lycamobile US International Roaming Rates 计费细则:"Data usage during international roaming is charged on a Pay-As-You-Go basis per MB. Minimum billing increment is 1 MB. Any partial MB usage will be rounded up to the next full MB."机制规则:Lycamobile 国际漫游流量不是按几 KB 精确计算的,而是不足 1 MB 按 1 MB 结算。实际扣费:中国区漫游流量资费一般为 $0.05 / MB 或 $0.10 / MB。即使你只跑了 321 KB(约 0.31 MB),系统结算账单时也会直接划走 1 MB 的全额费用($0.05 或 $0.10)。出处 3:交易与服务附加税/费根据 Lycamobile US Terms Section 1.4(Taxes & Fees):"Users agree to pay all taxes, fees, and regulatory surcharges applicable to the service, which may be automatically deducted from your Account balance." 每次账户发生 Pay-As-You-Go 扣费或触发漫游事件时,可能会产生 5% 的 Regulatory Recovery Surcharge 或小额的 911 / 地方电信附加税(通常为 $0.01 - $0.05)。 |
