How can I receive MMS picture messages on my Unlocked iphone 3g running on 3.1.3 Firmware?

Hi, try this:

1. Reset Network Settings. Go to Settings > General > [scroll down] Reset > Rest Network Settings

2. Reset All Settings. Go to Settings > General > [scroll down] Reset > Rest All Settings

3. Check if MMS is turned on in Settings > Messages

4. Restore your iPhone using iTunes, and set it up as a new iPhone instead of restoring the back up.

5. Check if you have new carrier settings available. Go to Settings > General > About to check.

6. Find the MMS settings for your Carrier on Google, and set them up in Settings > General > Network > Cellular Data Network > MMS

Hope this helps : )

some all of us is so unwell cautioned!! All you may desire to do is replace the settings on your telephone, to try this purely call shopper centers and that they're going to deliver them to you. Now for the particular clarification. whilst somebody sends you an MMS (photograph message), the community sends a kind 0 SMS to your telephone which includes an handle to your telephone to get carry of the message. Your telephone is configured to touch O2 with that handle that's why you get the unknown subscriber message as you're an Orange shopper. as quickly as your telephone is configured to communicate to the Orange MMSC (Multimedia Messaging provider Centre) that is going to paintings completely.
