I am having a problem. There are messages being sent to another users phone and when he replied to one the reply came to my phone as if I were the sender. I did not send the messages and the only Id is showed was 36425 (kinda like id from a IM). How can this be done and is there any way I can prove it wasn't me? Please help me if you can.

Welcome to Geekzone. You have to contact your mobile operator and explain the situation. The opeator will be able to help you (if they want to, some help desk services are just appaling!) by finding evidence that these messages came from other handset.

I thank you for your reply, but I have done that numerous times and they tell me it is impossible for me to receive a reply if I am not the sender. I am far from computer savy but I do know things are possible. I found a website where you can send a text message and enter the To cell# and a from#. I did that and entered my old cell# that I had disconnected on Sunday and it went through as if that # sent the message. It also had the 36245 ID#. The only problem is is on the message received it had the from# and the website address. These messages that have been sent did not? Oh and also how can a reply go to my phone if it was done as text/instant message (computer). I really need help. Thank you

It is very easy to spoof a sender address via several sites on the internet that do bulk SMS and the sender can be anything you want (ie numbers or letters).

You can have a reply go to where ever you want??? I know with instant message your reply will go to the computer, right and if you send one throug a computer how can the reply go to phone? I don't think I will be able to proof that this person has been doing this but I do want to prove it can be done. I just am a bit tired of sounding crazy to people, like I am grasping for straws. Thank you for your input. I really do appreciate it.

As I said, some help desk people are not there to help... Every time a SMS is sent the operator should be recording your handset identification, and other information. First because they need this for accountability.

If they can't prove you sent a message they can't charge. Easy, right? The operator will have the records to prove you sent it, or not.

If someone sends a message from a website, the operator will not have the sender records, only the receiver side.

Are you being charged for these messages? Does your operator have an online tool to check your usage?

What operator are you using?

I don't believe I have been charged. I did not see any record on my bill for a text message to that persons cell#. I have Cingular and I have been trying for about a month to figure out how this was done and no one would or could help me.
My bill does show data transfers but I do use my phone to pay my bill or check my e-mails. The bill only says data transfers it does not go into detail. I think the problem is Cingular does not see anything because it was not my phone that sent the messages.

Exactly...

I do understand that concept but how could a reply message from a computer generated text message come to my phone, is my dilemma.

I have heard of this, Someone sends a message to a recipient and it has a one-time reply path which goes to the users phone.. however it looks like the message ID went iffy this time.

I think the same thing may have happened to me. I received a few txt messages with a friends number displaying as the sender.
But my friend denies that it was her and we have had a big argument over it.

I was going to ask if it is possible for someone else to be using her number and it seems that it can be done. But what to do to stop it?
