Excuse me, I want to travel to Japan, how can I buy a Japanese traffic package? Please advise.

There are three ways to purchase the Japan Mobile Traffic Package.

1. Call the operator directly, open international roaming service, and then buy international roaming traffic packages with different prices, so that you can surf the Internet with your mobile phone in Japan. The advantage of this method is that you don't need to buy a local calling card, but the disadvantage of this method is that it is expensive and the signal is not necessarily guaranteed. You can only surf the internet with your mobile phone. If you are an ipad or a mobile phone, you need to turn on the hotspot through your mobile phone.

2. You can buy local portable wifi through a treasure or a travel network. The price of different traffic is different, but it is much cheaper than roaming traffic package, and there is a signal. Generally, the goods can be delivered before departure, or they can be picked up at the designated Japanese airport. This is the way most people choose to travel to Japan because it is cheap and convenient.

3. If you feel that it is inconvenient to travel with mobile wifi, you can also choose to buy a local mobile phone calling card in Japan and directly replace the sim card of your mobile phone, so you can surf the Internet directly with your mobile phone. The charges are also based on the package charges of local mobile phone operators in Japan, and there will be no roaming charges. However, attention should be paid to keeping the original domestic calling card of the mobile phone, because it needs to be replaced when returning to China.

There are two roaming modes: automatic and manual.

1, automatic roaming

Mobile communication network automatically tracks mobile stations and provides services to mobile stations at any location. Its main functions are location registration and call forwarding.

The function of location registration is to track the mobile station and record the location information of the visiting mobile station as the basis of call connection. In order to track the mobile station, the service of the mobile communication network is usually divided into several location areas, and one location area may include several base station areas.

Each location area has a unique identification code, also called area identification code, which is continuously transmitted on the control channel of each base station in the location area. The mobile station can move freely in the location area without location registration. When the mobile station finds that the received area identification code has changed, indicating that it has entered a new location area, it automatically turns on the transmitter and sends out location update information.

The mobile telephone office sends the received information to the visitor location register that controls the location area, and tells the home location register the current location of the mobile station through the signaling system between the location registers, and the home location register updates the location information of the mobile station.

And sends back information such as the category and service items of the mobile station, and the access location register sends a location registration confirmation message to the mobile station according to the received user information, so that the mobile station can obtain its registered communication service in the new location area without changing the original telephone number.

The home location register also sends a message to the visitor location register in the original location area of the mobile station to delete the related information of the mobile station.

Through manual registration, the roaming number of the visited mobile telephone office is assigned to the roaming mobile station, so that the mobile station can obtain communication services in multiple areas. The mobile user applies for registration to the home office, and the home office selects a number from the mobile phone number area predetermined by the visited office, assigns it to the user's mobile station, and informs the visited office.

The visited office regards it as a short-term user and establishes the corresponding user data unit. When the mobile station roams to the visited office, it can get service. If the calling user knows the location of the mobile station, he can dial the slow-moving number assigned by the visited office and connect to the visited office through the automatic telephone network, or he can call the roaming mobile station.

How to use domestic roaming:

1. Confirm that you have started domestic roaming service.

2. When leaving the city where the number is located, dial the other party's number directly (if the other party is a fixed line or PHS, the long-distance area code must be added in front).

3. Or dial 1795 1 first and then the other party's number.

4. Users who turn off the long-distance function can also purchase 17950IP calling cards and make long-distance calls when roaming.

5. Call Taiwan, Hong Kong, Macao: direct dial: 00+ area code+city code+other party's number or 00+ area code+other party's mobile phone number. You can also call 1795 1 to make an IP call: 1795 1+0+.

How to use international roaming:

1. You can handle international roaming in the business hall. The specific procedures shall be subject to the local announcement.

2. When roaming in Korea or Japan, you need to rent a dedicated mobile phone in China Mobile Business Hall. Roaming in American countries such as the United States requires using a three-band or four-band mobile phone.

3. When using the international roaming service, the name or network code of the local mobile operator will be automatically displayed on the mobile phone. If you want to select a network, you can select the network manually.

4. Each operator's network dialing method is different. Generally, local calls dial the called number directly, and international calls add the international long-distance access code and the called country code before the called number.
