How to recover from deleting SMS by mistake on smart phone?

1, cell phone call records and text messages cannot be restored if they are not backed up, accidentally deleted or restored after leaving the factory. If you are a Unicom user, you can log in to Unicom APP with the service password and verification code to check the call details. At present, it can only be queried for nearly six months. After logging in to China Unicom APP, you can click Service > Inquiry > Basic Business Inquiry > Call Details on the homepage to inquire about the call details within six months, including the call time and duration.

2. Unicom has no right to inquire because the content of the short message involves personal privacy. If you need to inquire about the details of SMS and MMS, you can log in to China Unicom APP, and click Service > Inquiry > Telephone Fee Business Inquiry > SMS and MMS Details on the homepage to inquire about the details of SMS and MMS within 6 months (SMS and MMS details only provide the records of the last 6 months).
