As the largest operator in terms of user base and revenue, China Mobile ought to set the benchmark for user service excellence. However, lately, the company has been inundated with user complaints, accusing it of various service shortcomings. Especially concerning the elderly, user feedback suggests that China Mobile's services are not sufficiently user-friendly. Given the elderly's lack of familiarity with smartphone operations and carrier charging rules, they frequently exceed their data usage limits. Unfortunately, China Mobile has failed to provide adequate attention and timely reminders regarding this issue, leading to some elderly individuals receiving exorbitant data bills.
