What do you need to pay attention to when activating international roaming?

(2) When the user handles the opening of international roaming business, the sales staff shall confirm the type of mobile phone terminal and mobile phone card with the customer, and strictly implement the principle of matching the machine card of 3G mobile phone inserted into 3G mobile phone and 4G mobile phone inserted into 4G card. If the UIM card does not match the terminal, you need to go to the physical business hall of China Telecom to replace the card.

You don't have to go to a business office to activate international roaming before you leave the country, depending on your mobile phone plan and service provider's regulations.

Take China Unicom international roaming as an example.

After China Unicom users activate the Hong Kong, Macao and Taiwan roaming permissions and international roaming permissions, they need to pay attention to the following:

1. Before leaving China, please know that China Unicom has roaming services in Taiwan, Hong Kong, Macau and countries or regions where international roaming services and operators operate, and will continue to expand the scope of roaming services in Taiwan, Hong Kong, Macau and international roaming services.

2. Due to the different frequencies of Taiwan, Hong Kong, Macau and overseas operators. If the user's mobile phone frequency does not support the frequency of the country or region where the user is located, the user will not be able to use the mobile phone to communicate in Taiwan, Hong Kong, Macau, and overseas. Before going abroad, users need to confirm whether the mobile phone they are using supports the frequency of the country or region they are going to.

3. Users in Taiwan, Hong Kong, Macau and overseas can choose to log in to the roaming operator's network by manually selecting the network (please click the link to enter the manual network selection method) to obtain the same high-speed service as Chinese mainland.

4. Due to the problem of cross-coverage of the operator's network in the border area, users are not allowed to be in Taiwan, Hong Kong, Macao and overseas, but due to the strong network operator's signal in Taiwan, Hong Kong and Macau, and overseas users' mobile phones can log in to the network operator in Taiwan, Hong Kong and Macau.

For example, near the border between Shenzhen and Hong Kong, users are in Shenzhen, but their phones are logged into the network of a Hong Kong operator. When a user dials ** at this time, the user's credit will be calculated based on the Hong Kong roaming charge. In order to avoid this, in border areas, pay attention to the carrier network name or ** displayed on your mobile phone, and if necessary, use the manual network selection method to select the Unicom network.

For international roaming by mobile phone, the precautions before leaving the country are as follows:

1. The mobile phone needs to enable international roaming functions in Hong Kong, Macao and Taiwan

When opening an account with a mobile phone number, the roaming function in international and Hong Kong, Macao and Taiwan is turned off by default, and if you need to visit, you need to open the roaming function in time for international and Hong Kong, Macao and Taiwan, and there are two permissions to choose from

1) Activate voice, SMS and data roaming permissions in international and Hong Kong, Macao and Taiwan regions at the same time;

2) Only enable voice and SMS roaming permissions in international and Hong Kong, Macao and Taiwan regions, but not data roaming permissions in international and Hong Kong, Macao and Taiwan regions.

There's nothing to pay attention to.,The last time I opened Telecom's overseas roaming, I opened it easily with real-name authentication.,It's very convenient.。

After China Unicom users activate Hong Kong, Macao, Taiwan roaming and international roaming permissions, precautions for outbound (visiting) roaming:

1) Before leaving the country, please check whether China Unicom has opened Taiwan, Hong Kong, Macao roaming and international roaming services with the operators of the countries or regions to which the user goes, and will continue to expand the scope of Taiwan, Hong Kong and Macao roaming and international roaming.

2) Due to the different frequencies of network use of Taiwan, Hong Kong, Macao and overseas operators. When the user's mobile phone frequency does not support the frequency of the country or region to which the user is visiting, the user will not be able to use the mobile phone communication in Taiwan, Hong Kong, Macao and overseas. Before leaving the country, users need to confirm whether the mobile phone they are using supports the frequency of the country or region they are going to.

3) Users can choose to log in to the network of the roaming operator in Taiwan, Hong Kong, Macao and overseas through manual network selection (please click the link to enter the manual network selection operation method) to obtain the same high-speed service as in Chinese mainland.

4) Due to the problem of cross-coverage of the operator's network in the border area, the user may not roam in Taiwan, Hong Kong, Macao and overseas, but the user's mobile phone logs in to the network of Taiwan, Hong Kong, Macao and overseas operators due to the strong network signal of Taiwan, Hong Kong, Macao and overseas operators. For example, near the border between Shenzhen and Hong Kong, the user is in Shenzhen, but the user's mobile phone is logged into the network of the Hong Kong carrier. In this case, when a user calls **, the user's call fee will be calculated based on the Hong Kong roaming charge.

In order to avoid this situation, please pay attention to the operator network name or ** displayed on the mobile phone when in the border area, and if necessary, please select the China Unicom network by manually selecting the network.

5) Before leaving the country, please charge the mobile phone battery and bring the charger that matches the battery to prevent the mobile phone from being unusable and inconvenient to the user.

6) The power plug in some countries is different from the power plug standard and voltage in China, the user can ask the hotel where the user stays to provide the conversion plug, and the user who often leaves the country had better prepare a multi-functional power conversion plug to meet the needs of the power socket of different standards and voltages.
