1. Notice of Enterprise Name Approval
2. Copy of legal representative's ID card
3. Invoice for payment of telephone bills under the legal representative's name
By submitting the above documents and filling out the account opening form, you can activate the 400 hotline. After the information is reviewed and approved, you can activate it within 1-3 working days.
