After editing Huawei P 10 Plus information, the send button is gray and cannot be clicked.

If the recipient information is not added, the "Send" button will be grayed out and cannot be clicked.

When the SIM card is wrongly recognized, the "Send" button will be grayed out and cannot be clicked.

Solution:

Please add recipient information and try again.

Please restart your phone and try again.

If you are using card cutting, please change the standard SIM card in the business hall. Cutting the card may cause the information function not to be used normally.

If the above methods still can't solve the problem, please take the purchase invoice to the after-sales outlets for testing.
