Can I make a phone call when traveling abroad and the mobile phone is not enabled for international roaming?

You can't make a phone call abroad without international roaming, because if you don't open international roaming service, your mobile phone will have no signal abroad. If someone calls you, it will prompt that the number is not in service area and the short message cannot be received normally. The specific steps for opening international roaming are as follows:

1. Open online business hall 10086. On the official website page, enter your mobile phone number and service password to log in.

2. Next, in the opened page, click the menu item "Doing Business-Enabling Roaming Function" at the top of the page.

3. Next, in the opened page, click the "Online Processing" menu button.

4. Finally, in the pop-up page, click the "Handle Now" button to open the international roaming function.
