Is it true that only telecom mobile phones can receive and send successful reminders?

You can receive a receipt, but because it is a cross-carrier network, the status report can only inform the user that the short message has been sent, and can't provide a real status report. SMS receipt refers to the business that customers receive the receipt message immediately after sending the message with China Telecom's mobile phone. The contents of the receipt include the status information and additional information of whether the receiver successfully received it. The length of additional information is limited to 44 characters (including punctuation marks), and the content involves cultural entertainment, life health, practical knowledge, hot events and other fields. Anyone who is a mobile phone user of China Telecom Tianyi can apply. This business can be handled through SMS, Huan go website and handheld business hall.
