Hi Kim, Contact your provider and ask them to send you there WAP and MMS settings, usually when you recieve theese you switch off your phone, power it back up and YOU need to send a picture to activate the MMS settings with your provider. Good Luck!

Profile name - Multimedia

GPRS Settings (open it)
IP Address -
Port - 8080
APN - wap.cingular (case sensitive)

Mms does not work, i am UNABLE to send pic msgs. plz help


I suppose you havenot got the MMs settings from your service provider.

Please call your service provider and ask for the settings. When they send it please save it to your phoneand make it as a default settings so that your phone uses this setting when you send MMS.

In settings there is an option called as ALLOW MMS RECEPTION, please put this to ON,

To go to Allow MMS RECEPTION option follow the steps

Menu----->message----->message settings----->MMS setting------>allow MMS reception

Now you can use MMS

Hi, and welcome to FixYa!

I've been doing some research on your problem of not being able to receive MMS messages (pictures) on your phone. There are a couple of reasons why you may not be able to. I'll list them in order:

1) Your cellular provider may not have MMS activated for your phone. Contact your provider and ask if MMS is enabled on your line.
a) If they tell you, no - it is not currently enabled, then ask them to enable it for you.
b) If they tell you, yes - it is currently enabled, ask to speak to someone in Tech Support. Inform Tech Support that you are not receiving MMS messages but instead, an 'Unknown Subscriber' message although you have MMS currently activated on your line. Most Tech Support Departments can send a 'packet' to your phone that you will simply click on when you receive it - and download it on your phone. That should solve the problem.

There is one more problem I discovered. If the picture you are sent is too large for your phone's screen to display you might also receive this, 'Unknown Subscriber' message.

Regardless, your first call should be to your cellular provider to ask assistance with your MMS settings.

I hope this information will help you.

Everytime i get sent a picture in a text, but when i try to open it, the phone says unknown subscriber and will not let me open any of the MMS texts i recieve.

Ring your network they will send you a code which you can save and it will allow you to recieve mms picture messages.

Hope it helps

When you receive the message with id and password, it usually means that either your phone is not multimedia messaging compatible or your account is not provisioned with the actual multimedia messaging feature itself.
If unable to send or receive a picture message (MMS), troubleshoot accordingly:
  1. Attempt to connect to MEdia Net on the device. Connectivity to MEdia Net confirms the device has enough signal strength and GPRS availability to send and receive MMS.
  2. Verify MMS is being sent to an AT&T subscriber. If MMS message is being sent to someone other then an AT&T wireless services subscriber, verify that the carrier is supported.
  3. Picture messaging settings are pre-configured on all devices purchased from AT&T. If the settings have been altered or if the device was not purchased from AT&T, validate picture message settings are properly configured.
  4. Attempt to send an MMS again.
  5. If further assistance is required, please contact Customer Care.

If problems occur, please perform the following troubleshooting steps:
  1. Verify device has signal strength.
  2. Check for a GPRS attach on the device.
  3. Verify the browser settings are correct.
  4. Clear the browser cache.
  5. Power cycle the device (turn off and back on).
  6. Attempt to access MEdia Net again.
  7. If unable to access a particular MEdia Net site, check to see if the site is supported by AT&T.
  8. If problem persists, please contact AT&T Customer Service for wireless customers.
