Can China Mobile's mobile phone card be used in Vietnam?

You can use domestic roaming in Mang Street, Vietnam, and the cell phone signal is better. Going to Vietnam 12 km, there is basically no signal in China, so if you want to use your mobile phone in Vietnam, you must open international roaming, and there is no problem in communicating signals in major cities in Vietnam.

Opening related international business in the business hall:

Pay a deposit of 2000 yuan to Mobile, and Mobile will help you open international telephone service, that is, you can make international long-distance (Vietnam) calls at home or in Vietnam. The mobile phone has a signal, so you can make phone calls and receive text messages.

2. Pay 1000 as deposit, but only for making international calls at home. (That's what I do)

There are many calling cards in Vietnam, so VIETTEL is generally chosen. It is cheaper to call China, about 1 RMB. There are several prices for cards, and the face value inside is different. Usually buy a recharge card to recharge. Ask clearly when you buy a recharge card. There are often company promotions, such as how much to buy for you. However, the best way to call China is to use the Internet. Internet cafes buy calling cards, just like using IP cards. Just enter the card number and password and you can use it. Just a few cents a minute, probably less than 1 minute.

International roaming means that users can also enjoy a series of services provided by telecom operators abroad, such as phone calls, short messages, multimedia messages, mobile Internet access and so on.
