I have a Unicom mobile phone. Why do I always get roaming messages abroad?

As you said, SMS will be sent automatically, which does not rule out that it is caused by mobile phone poisoning or installing third-party software. In the case of mobile phone poisoning, it is recommended to disinfect the mobile phone as soon as possible; If the installation of third-party software is caused by improper settings, it is recommended to reset or uninstall the software. Specifically, you can also contact Unicom customer service to verify the relevant deduction.

You can log in to the online business hall/click on the phone bill query > bill query > detailed list query > detailed list of SMS and MMS, and you can query the detailed list of SMS and MMS in the last six months (including the current month).
