eSIM在5G上不工作 — 切换到4G

5G问题——为什么切换到4G通常能解决eSIM问题

5G网络仍在全球范围内建设中。在许多国家，5G覆盖主要存在于市中心，但在其他地区信号会迅速减弱。如果您的eSIM显示5G信号但网页无法加载，请尝试切换到4G/LTE。

为什么5G可能导致问题

覆盖不稳定：在许多国家，5G覆盖不够稳定，特别是在主要城市以外的地区
网络切换失败：您的手机可能会锁定在弱5G信号上，而不是强4G信号
运营商兼容性：并非所有运营商协议都包含漫游eSIM的5G接入

如何切换到4G/LTE

iPhone

前往设置 → 蜂窝网络
点击您的Bcengi eSIM线路
点击语音与数据
选择LTE而不是5G自动或5G开启

Android

前往设置 → 网络和互联网 → SIM卡
选择您的Bcengi eSIM
点击首选网络类型
选择4G/LTE

Samsung

前往设置 → 连接 → 移动网络
点击网络模式
选择LTE/3G/2G（自动连接）而不是5G/LTE/3G/2G

何时切换回5G

当您在已确认有5G覆盖的主要城市时，或者回到家中时，可以切换回5G。4G/LTE提供10-100 Mbps的速度，对于流媒体、视频通话和浏览网页来说已经绰绰有余。
