Xiaomi 2S can't receive short messages after changing the telecom 4G card.

Hello, first of all, thank you for your support to China Telecom. I hope the following answers can help you. Xiaomi 2s mobile phone is the 3g mobile phone of China Telecom, and it does not support the 4g network standard of China Telecom, so it cannot use the 4g mobile phone card. Please cooperate with the 3g mobile phone card of Telecom.
