Can China Mobile change its card without changing its number? I'm using a M-Zone card now. I want to switch to 4G traffic king. Can I just change the card without changing the number?

Hello, you need to change your card, because the 4g card is different from what we used before. Detailed process, you need to go to the local mobile business hall to apply for a 4g card you want to change. You can change the card yourself. You need to send a text message to 10086. You can also ask him to change it for you in the business hall. In addition, 4g cards are divided into large and small cards. For example, if you used to use a big card, you need to change it to a big card or a small card. For example, Apple needs a small card for more than 5s. I hope it will help you, and finally remind you that you need to bring your ID card to change your card.
