Two people in different places, the amount of text messages is huge every day, which is too expensive. Is there any way to solve the problem of mobile card?

You can ask the local 10086 if there is a sweet talk package service. If so, I suggest you open that service. The sweet talk package fee is as follows: call 1795 1 any China mobile number (regardless of long distance or short distance, long distance) 1000 minutes, only charge 100.

If you want to send short messages, you can open Fetion. Fetion is free, and sending short messages is also free, but it will generate traffic charges. I suggest you set a monthly traffic of 10M for 5 yuan, and the monthly traffic can probably send about 1300 short messages!
