The boarding pass link in China Eastern Airlines SMS can't be opened.

There may be many reasons why the boarding pass link cannot be opened in China Eastern Airlines SMS. Here are some possible reasons and solutions:

1. Invalid link: The link may be expired or invalid. You can try to contact the customer service of China Eastern Airlines, provide relevant information and re-apply for boarding pass.

2. Network problem: If your mobile phone is in an unstable network or weak signal environment, the link may not load normally. It is recommended that you try to connect to a more stable network or move to an open area, and then try to open the link again.

3. Mobile phone settings: Some mobile phones may impose security restrictions on the links in the SMS, which makes it impossible to open them. You can check your phone's security settings or browser settings, and try to adjust the relevant options to allow the link to open.

You can try to open the link with another device or browser, or try to update your phone or operating system to the latest version. If the above methods still can't solve the problem, I suggest you contact the customer service of China Eastern Airlines directly, provide detailed information and seek their help and guidance. They will be able to provide you with more accurate and professional solutions.
