One plus SMS display date

If you add a mobile phone, there is a possibility and solution if the short message function does not display the date. 1. The number of SMS service center may be lost due to misoperation. Please contact the operator, that is, the customer service of China Mobile or China Unicom, for the correct service center number, then change the number in SMS-Settings-Service Center, and then restart your mobile phone to send SMS.

2. If you still can't solve the problem, you need to put your mobile phone card in another mobile phone. If all the cards in the mobile phone can't send short messages, please back up the information, download the firmware package and upgrade or refresh the mobile phone in official website.

3. None of the above methods are effective. You need to go to the customer service center to test your mobile phone.
