eSIM 在 5G 下无法使用——切换到 4G 解决方法

5G 问题——为什么切换到 4G 通常能解决 eSIM 连接问题

5G 网络在全球范围内仍在持续建设中。在许多国家，5G 覆盖仅集中在市中心，信号衰减较快。如果您的 eSIM 显示 5G 信号但无法加载网页，请尝试切换到 4G/LTE。

5G 可能导致问题的原因

覆盖不稳定：许多国家的 5G 覆盖参差不齐，在大城市以外尤为明显
网络切换失败：手机可能锁定在微弱的 5G 信号上，而非更强的 4G 信号
运营商兼容性：并非所有运营商协议都为漫游 eSIM 提供 5G 访问权限

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，而非"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），而非 5G/LTE/3G/2G

何时切换回 5G

当您身处有确认 5G 覆盖的大城市时，或返回国内后，可切换回 5G。4G/LTE 可提供 10–100 Mbps 的网速，完全满足流媒体播放、视频通话和日常浏览的需求。
