Hi Charlie.
Thank you so much for the quick response and for taking the time to help me out! I did as you instructed. Embarrassingly enough, I bugged a friend living across the country on the coast to help make the call to China Telecom. Apparently, they did a “reset” and connection seems decent for now. Fingers crossed, no more issues from here on.
Thanks again a bunch! Happy new year!

P.S. For newcomers facing similar issues, China Telecom’s hotline for customer service is 10000. Unfortunately, for non-Mandarin speakers, the instructions are in Mandarin.
