If the mobile phone is seized by the police, will it have an impact? Will WeChat and calls be monitored?

It doesn't matter, WeChat and calls will not be monitored. Collecting mobile phone cards at the police station is the need of the public security organs to collect in accordance with the relevant provisions of the standard information collection, and will not affect the future work and life of the collected people.

Under normal circumstances, when the police perform official duties, they can take people who do not carry their ID cards and cannot produce them to the police office for identity verification. According to the relevant regulations of information collection, normal police work needs to take photos to collect DNA.
