Telecom version of Xiaomi 2s SMS cannot be sent.

Hello, dear users. It's my pleasure to serve you. According to the information you provided. The analysis is as follows:

1. Check whether the phone settings are correct and whether the surrounding signals are normal.

2. Pull out the card, reinsert it, and restart the phone to try.

Try to replace a normal telecom card. If the problem is solved, go to the telecom business hall and ask the staff to test your card and solve the problem.

4. If the card is changed, the problem still exists. Go to the mobile phone after sale and ask an engineer to help you solve the problem.

I hope my answer can bring you some help and be adopted by you. Thank you.

If you want to know more, please come to Zhihu platform of Anhui Telecom or online business hall of Anhui Telecom to ask questions, and there will be more professional customer service to answer your questions.
