I am going to study abroad soon, and I don't want to stop using my domestic mobile phone number for several years. What should I do?

You don't have to stop if you want this SIM card in the future. In the past, everyone had only two choices, either to turn off the phone number and reopen it after returning home, and to use a little basic monthly fee. Another option is to change your original package to the one with the least monthly rent. For example, you used to be in the dynamic zone, and you had to deduct ten to dozens of monthly rents every month.

If you want to save money when you go abroad, I suggest you download the worry-free APP. As long as you register an account in the APP with your mobile phone number, you can host the domestic mobile phone number. You can also receive domestic short messages when you go abroad, or you can use the APP to make overseas internet calls to your family. My brother has been abroad for a year, and we often communicate and chat.
