Internet and MMS settings
To send multimedia messages, or to access the Internet when there is no available Wi-
Fi® network, you must have a working mobile data connection with the correct Internet
and MMS (Multimedia Messaging Service) settings. Here are some tips:
•
For most mobile networks and operators, Internet and MMS settings come pre-installed
on your device. You can then start using the Internet and send multimedia messages
right away.
•
In some cases, you get the option to download Internet and MMS settings the first time
you turn on your device when a SIM card is inserted. It is also possible to download
these settings later from the Settings menu.
•
You can manually add, change or delete Internet and MMS settings on your device at
any time. If you change or delete an Internet or MMS setting by mistake, download the
Internet and MMS settings again.
•
If you cannot access the Internet over a mobile network or if multimedia messaging is not
working, even though the Internet and MMS settings have been downloaded
successfully to your device, refer to the troubleshooting tips for your device at
www.sonymobile.com/support/
for network coverage, mobile data, and MMS issues.
If STAMINA mode is activated to save power, all mobile data traffic gets paused when the
screen is off. If this causes connection problems, try excluding some applications and services
from being paused, or deactivate STAMINA mode temporarily. For more information, see
STAMINA mode feature overview
on page 115 .
