How to use mobile phones when traveling 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 it is no problem to communicate signals in major cities in Vietnam.

First of all, is your mobile phone mobile or Unicom? Then you go to the relevant business hall to handle it.

Take moving as an example:

Opening related international business in the business hall:

1. Pay a deposit of 2000 yuan to Mobile, and Mobile will help you to open international telephone service, that is, make international long-distance (Vietnam) calls in China or make calls in Vietnam. If the mobile phone has a signal, you can make calls and receive short messages.

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

However, I don't know why. When you go to Vietnam, your mobile phone also has a signal, so you can make a phone call or send a text message. My mobile friend doesn't know what's going on, saying that it will only happen if I pay 2000 yuan ~

Then after you return to China, the phone bill will be deducted according to your real-time phone bill, and then you can move with the original documents of the original business and refund the deposit.
