What's with the overseas phone call?

With the development of globalization, more and more people go abroad to travel, work and study, so overseas telephone calls are becoming more and more common. However, some people may encounter the situation that their mobile phones always have overseas calls. What happened?

Global roaming

If your mobile phone is enabled for international roaming, when you are abroad, your mobile phone will automatically connect to the local mobile network, so that you can make calls, send and receive short messages, etc. However, this will lead to high roaming charges, so it is recommended to turn off the international roaming function before leaving the country.

Phone Fraud

Some overseas calls may be telephone fraud, and fraudsters will pretend to be banks, public security, express delivery and other institutions to defraud your personal information and property for various reasons. If you receive such a call, you must keep calm, don't believe the other party's words, and call the police in time.

Dial the wrong phone number

Some overseas calls may be dialed wrong, or the other party dialed the wrong number. In this case, you can hang up the phone directly, or tell the other person that you can't speak the language he uses and let the other person hang up.

There may be many reasons for frequent overseas calls by mobile phones, and different measures need to be taken according to the specific situation.
