How to open Sichuan Mobile's home coordinates through SMS?

I suggest using the Tianyi student package of Telecom. The specific fee is: 19 yuan monthly rent, and the local call on campus is only 0.08 yuan/minute (quite cheap), including 300 short messages and (40 minutes of free talk time and 30 meters of internet traffic), which are very attractive package fees! In addition, you can set up five home numbers (nationwide) to call for free. If you are a friend in love, this is the package you want to choose. You both use the Tianyi package, which is equivalent to buying a walkie-talkie for free. In addition, if you like students who surf the Internet, the activity you are organizing now is to deposit 60 yuan/month+Tianyi mobile phone to send calls to 60 yuan/month (equivalent to free broadband), which is very cost-effective ~, I hope my suggestion can help you.

In the real society, it is simple, practical and affordable!
