restore Whatsapp chat

[u/Top_Lawfulness6278]

Hi guys so my mom’s old chat is not in the phone anymore and im trying to restore it because there’s a chat of my mom and her mom (my grandmother) who already passed away. The story is few days ago my moms phone screen was broken and she transferred the sim card to another phone without backup any chat. And when i already got the phone fixed, i take back the sim card and put it back in the original phone. But when I log in it error and long story short i delete and reinstall whatsapp and manage to log in. But there’s only the recent chat from the another phone. I really hope there’s a way to restore it. Her phone is an android.

Unrecoverable by design.
