The newly activated telecom card can't make phone calls, send text messages, and call to say that this service has not been opened, but you can consult experts online.

Call 10000 with other telecom mobile phones to report an error, and check whether the number status is normal. If it is a post-paid number, it will be activated when it is accepted. If it is a prepaid number, after the real-name information is registered successfully, insert the smart card into the mobile phone to make a charge deduction call (which must be connected and generate a charge), send a charging short message or use the mobile phone to surf the Internet to generate an online charge record for activation. If the words "Enter PIN" are displayed after the smart card is inserted into the mobile phone, please enter your PIN code (initial code is 1234), and the mobile phone will automatically find and enter the China telecom network.
