Can I use my mobile phone normally abroad?

Before going abroad, you need to open international long-distance and international roaming services in the business hall of mobile phone operators, so that you can use your mobile phone to make calls or surf the Internet in other countries. It is also necessary to confirm whether the frequency band supported by the mobile phone matches the carrier network of the destination country.

In order to save costs, you can choose to buy a local SIM card after arriving in the destination country and use the phone number and data service of that country. The cost of international roaming is usually high, so when you are not using your mobile phone, you can turn off the data roaming function to save money. If your mobile phone supports dual card dual standby function, you can use a domestic SIM card and a local SIM card, so that you can keep in touch with China and enjoy local communication services.
