As the title states, I have trouble activating the metro card on Alipay particularly for Nanjing. There is always an error stating "Please fill in your mobile no. correctly" no matter how I input my Singapore number. I had no trouble activating the metro card for Beijing on Alipay though. Is it due to the Nanjing one needing a local China phone number? Or what is the correct format of the phone number I should input?
Alipay’s metro card feature in different Chinese cities sometimes has different requirements for activating a card. The error you’re seeing for Nanjing, “Please fill in your mobile no. correctly,” is common for users trying to use a foreign phone number.
Reason:
Unlike Beijing’s metro system, Nanjing’s metro card linked via Alipay currently requires a local China mobile number for verification. This is because the system uses SMS verification codes that can only be delivered to Chinese numbers.
Correct Format:
Options for Foreign Travelers:
In summary, the error is due to Nanjing metro requiring a local Chinese number, unlike Beijing. If you plan to stay in Nanjing for a short time, the easiest solution is to buy a physical metro card at the station.
