What is the concept of omniscience?

"Full Intelligence" is a new service developed on the basis of PHS, and its functions are basically the same as PHS. The main difference is that the deduction of monthly fee and telephone call is different from the payment form of telephone call. "Full Smart" can only make calls after purchasing the "Full Smart Prepaid Card", during which it can check the phone bill in real time. When the recharge balance on the recharge card is 0, the all-in-one machine can't talk, and can only dial the free service number (1 10, etc. ) and "all-in-one" service number, but can answer incoming calls. The "One Card" service is used through prepaid cards, and it is temporarily impossible to pay the phone bill through banks or cash.
