Mine is a motorcycle V3i mobile phone. There was an undelivered multimedia message in that mailbox recently, which could not be deleted. Please help me.

Hello, unsent messages are saved in the Outbox. You can delete them in the Outbox. If it can't be deleted, it may be caused by your misoperation. I suggest that you take your mobile phone to the customer service and ask the staff there to check your mobile phone. Your problem will be solved in a few minutes.

The above is my answer to you. I hope my answer can help you.

Or use the data cable to operate on the computer.
