Why can't I find the SMS of Unicom 1 yuan 1.5g traffic package?

if you are referring to the 1.5G intra-provincial traffic semi-annual package in 1 yuan during the preferential period, you can try to send YL to 11 to inquire about the remaining traffic of the intra-provincial traffic semi-annual package. You can also log in to the online business hall/click on the phone bill query > usage query

> the remaining half-year traffic package, and you can query the usage and validity period of the half-year traffic package.
