一.账户问题
1、我的账号可以更改账号信息吗？
可以，在设置界面，您可以修改自己的个人信息。
如果您的手机号或者邮箱出现变更，请及时修改个人信息。
2、如何修改我的登陆密码？
在设置界面，您可以修改自己的登陆密码。
在登录页面，您可以通过邮箱验证来重置登陆密码。
4、系统默认时区是多少？我可以自由切换时区吗？
系统默认时区是UTC0时区，在设置页面，您可以自由更改时区，刷新生效。修改后交易数据会跟随您的时区变动。
4、如果出现异常登录，我会收到通知吗？我可以在哪看异常登录？
如果出现异常ip登陆，我们会为您发送邮件通知您。在设置界面，您可以查看登陆时间和登陆ip历史记录。
二.充值问题
1、正常U提现到账的一般是多久时间？从充值到提现，正常情况下15分钟内即可完成全过程。
2、是否有特殊时间到账缓慢？例如早上9点以前，晚上6点以后？
充值U提现USD至钱包是7*24小时处理，不受时间段限制。但如果是付款到境外银行账户，工作日9:00-17:00发起的将当天出款，此时间段以外发起的则延后一个工作日处理出款。
3、周末，节假日是否能够正常时效到账（香港账户)？如不能一般是什么规则？
充值U提现USD至钱包不受节假日、周末影响，全天候处理。但付款到境外银行账户会受工作日影响，非工作日发起的交易将在下一个工作日处理。
4、目前的账户是否支持美金换人民币并进行FB消费？
目前涉及U承兑过来的美金都不支持兑换成人民币。此类资金无法直接用于需要人民币结算的FB消费。
三.支付问题
1、什么我使用gopay卡支付时没有显示成功？
您可点击交易明细>原因了解到更多交易讯息，失败的交易中能查看到失败的原因。
常见支付失败原因为：
1) 余额和手续费不足： 当前余额不足以完成扣款，请及时转入资金；
2) 有效期有误或安全码（CVV）有误： 信息输入错误，请确认之后重试；
3) 卡无效：卡冻结或已注销，请换卡支付；
4) 支付超时：网络延迟等，可稍后重试；
5) 限额不足：共享卡设置了单笔/日/月/总限制，限制不足时消费失败，可根据提示重新调整共享卡限额；
6) 商品类目不支持：消费的商品属于高风险品类，渠道暂不支持，例如黄、赌、毒等
