据群友测试，在插入外置esim的安卓设备上，用a配置文件成功开启vowifi后，开启飞行模式，再切换到b配置文件可以绕过b卡的ip校验，继续维持vowifi状态
推测安卓有关vowifi启用条件鉴权是在本地完成，切换配置文件由于是同一张实体卡的缘故不会二次鉴权
a卡使用telekom，umobile，tello，xox，UltraMobile，b卡使用giffgaff，均可正常复现

Mr. Durov launched Telegram in late 2013 with his brother, Nikolai, just months before he was pushed out of VK, the Russian social-media platform he founded. Mr. Durov pitched his new app—funded with the proceeds from the VK sale—less as a business than as a way for people to send messages while avoiding government surveillance and censorship.
Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
