Freshman, about to go to college in other provinces, I now use the mobile phone number bound to Alipay, online banking, QQ and so on. Can I go abroad without changing my number?
Yes, if you have a mobile card, you can change it to a GSM package or a 4G package, so you don't have to roam around the country, but people will call you long distance. Or you can open a family in two cities, 5 yuan a month. As for Unicom or telecom, I don't know much about it for the time being, but there should be a solution. You can consult the relevant business hall.
