IPhone sending duplicate text messages

[steelersgirl83]

My I Phone 4 is sending duplicate messages to a number of different contacts in my phone.  There is no record in my text messages that this is happening.  Please help!! Thank you!

That is very strange that your iPhone is sending duplicate messages. How long has this been happening? Have you sent yourself a message to yourself? Does it come in duplicate?  Are you using a 3^rd party app for messages? Have you had any other issues the device? Please answer these questions so I can resolve the messaging problem. Thanks.
