Sichuan Tianfu Health Link failed to get a mobile phone.

Network signal difference. According to the related information of Health Link, Sichuan Tianfu Health Link can't get a mobile phone because the network signal is not good. The reason why the health code can't be received is that the mobile phone number is in arrears, or the network signal is poor, so I changed the network and paid the fee. You can't get the verification code when you apply for a health code, but the signal was not good at that time, or there were many people applying for a health code. You can exit the page of applying for health code first and try again later. A few operations are sure to apply for success.
