No Network Available Z750a

We recently upgraded to the Z750a. Since then, our phones have been receiving text messages more than an hour late, and frequently show "No Network Available" on the display. Our previous phones (also Sony Ericsson) never had this problem. The only way I can get a connection is to turn it off and turn it on again.

Has anyone else reported this issue? Is there a solution? Thanks.

Re: No Network Available Z750a

What is ur old phone. It may not be the 3G phone? Z750a is a 3G phone. I think it could be because of 3G strength in your area. Check the 3G signal in your area from the website. Best think is switch off the 3G. Hope this helps you.

Our previous phones weren't 3G. Tried your solution a few hours ago and so far, so good!

Thank you. Smiley Happy

Re: No Network Available Z750a

Z750a is USA ATT firmware and Z750i is international (Sony Ericsson version). I tried the software and able to OFF 3G. This software works not only for Z750 but also for couple of other phones too. Once you dowload and install you will see a list of phones.
