Why can't I send a short message on Red Rice note2? The signal is fine, just reset it.

I suggest you try to solve the problem in the following ways:

1. First, please check whether the SMS center number is correct (please consult the customer service of the operator of the network you are using for the correct SMS center number);

2. Turn on the option of always receiving MMS (System Settings-All Settings-Mobile Network-Always Receiving MMS);

3. Ask the operator whether to start the mobile Internet service. MMS can only be sent successfully if it has the function of "mobile internet service", but there is no traffic charge, and operators charge according to the number of messages;

4. Whether the selected attachment of the sent MMS is too large, operators generally have strict size restrictions on the pictures sent by MMS. Please consult the operator for details.

5. Replace the sim cards of different operators and try to send them;

6. Back up and empty all data, upgrade to the latest version, and then try to send;

7. If the above methods can't be solved, it is recommended that you take the machine to a nearby Xiaomi home or an authorized maintenance point for testing.
