1. If you don't want to change the number or add a card, consider changing the high-traffic package. Yes: log in to the operator's APP self-service. Call the operator's customer service phone and consult the manual customer service. Bring valid identity documents to the offline business hall.
2. If you don't want to change the number or add a card, you need to transfer to the network. You only need to bring your valid ID card to the offline business hall of the network transfer operator.
3. There is already a primary card, so you can consider adding a secondary card as a flow card. You can minimize the package fee of the main card and keep the number card. Then APPly for a new number card as a running card through the operator app, manual customer service, or offline business hall.
4. There is no number card, so you need to apply for a new card. Bring a valid ID card directly to the operator's offline business hall, and then insert the mobile phone to activate it.
What preparations need to be made before handling the number card:
1. Count how much traffic is needed every month.
2. Clear the regional scope of traffic use. Traffic cards can be divided into national traffic cards, provincial traffic cards and urban traffic cards. The wider the area, the higher the traffic fee.
3. Consult the use of the number cards of friends around you and compare the signal strength and stability of the number cards of the three major operators where you live.
4. If you consider handling a 5G traffic package, first consult the operator's customer service and ask if there is 5G signal coverage in your residence.
5. Make clear the consumption direction of your own traffic. If the traffic is relatively concentrated, you can find out whether there is a directional traffic card corresponding to the APP, because the directional traffic card is cheaper than the general traffic card.
6. Make it clear whether you need to apply for a new card or just change the package.
