Try the new FW for SE VIVAZ U5i using Update Service from SE: R2CA026.

if this didn't work, try this:
go to
menu/ seting/connectivity/admin.setting/packet data

then choose "when required'

My sony ericsson vivaz is not sending text messages..my sim card is working..


Please try to check the SMS network configuration settings of your phone through your Service Provider. They need to reconfigure your account to activate this feature on the phone.
If this seems to be fine, then try the following:
1) Go to your outbox and cancel sending the message. It should have an X on it or something.
2) Take out your battery without turning it off first.
3) Remove your SIM card and put your battery back in.
4) Boot your phone back up without the SIM card.
5) After it boots all the way up, remove the battery again without turning your phone off.
6) Put your SIM card and battery back in and turn your phone back on.
7) Go to your outbox and delete your canceled message(dont try sending it again).
