How should I send SMS to Russia? How much do you charge?

For example, the mobile phone number in Russia is 89 * * * * * * *, so when sending a text message, enter+79 * * * * * * * in the receiver's place. China Mobile can't send short messages to all Russian mobile phones, but Unicom can. It seems that China Mobile can only be sent to Russians. Delivery fee 1 yuan. Receiving is free. For example, the Russian address to China is+8613 * * * * * * *. /kloc-the one at the beginning of 0/5 has not been used, and it is unclear.
