Weekly point: Many iPhones have battery drain errors, Pi Network prices hit bottom


(Dan Tri) - Outstanding technology information last week included 13 million subscribers at risk of being revoked, Pi Network's record price drop, OpenAI launching its first hardware device.
Deadline for 13 million subscribers whose information has not been standardized

This is the result of the campaign to standardize subscriber information according to Circular 08 to clean up the database and manage mobile SIMs more strictly. To date, telecommunications enterprises have transferred data of more than 114 million subscribers to the national population database, of which more than 96 million numbers have been successfully confirmed.
Resolutely reviewing the owner's SIM is considered a necessary step to build a safe and transparent telecommunications environment. According to the Department of Telecommunications, mobile SIM is currently one of the most commonly abused tools to spread spam calls and spam messages. Standardization will help limit this situation and protect users' rights.
Pi Network has a record price cut
According to data from the Bitget exchange, Pi Network price has dropped to 0.0704 USD in recent days. This is a record low since Pi Network coin was listed on exchanges.

In groups about Pi Network on Facebook, the community is no longer as active as before. Posts with content about collecting Pi or buying Pi in bulk also no longer appear.
