Unlocked Motorola phones may encounter problems when you try to send picture messages (also known as MMS) on your mobile provider's network. The unlocked phone does not have the proper settings that allow it to connect to your provider's messaging network. You can add these settings yourself to set picture messaging to work on the Motorola. The verbiage for screen selection varies slightly based on your Motorola model.
Instructions
1. Press the "Main Menu" key on the main screen of the Motorola.
2. Select "Messages" or "Messaging" and then select "Menu."
3. Select the option for "Message Setup" or "Inbox Setup."
4. Click the selection for "MMS Message Setup" and then select "Change."
5. Click the option for "Server Info" or "Service Info."
6. Clear out any entries that currently appear in the fields. To delete, select "Menu" and then "Delete."
7. Select "New Entry" and then "Service Name."
8. Enter the name for your mobile provider (such as Sprint).
9. Select "Server Name" and enter your provider's server name, such as "http://mmsc.cingular.com" for AT&T.
10. Select "Done" or "Save."
11. Select "Menu" and then select "Set Default" to finalize the MMS setup process.
