I have handled 500 SMS packages in 30 yuan in the M-Zone. If I send a text message to Unicom users, how can I calculate the tariff?

One: At present, the monthly M-Zone package in most areas includes off-network, that is, sending short messages to Unicom and PHS;

Two: roaming fee is 6 cents per minute+long distance fee is 7 cents every 6 seconds;

Third, the landlord can also call the local China Mobile Customer Service Phone 10086 for further consultation and confirmation! The landlord can change hands and move the station according to the voice prompt!

Please accept my answer! Happy new year!
