How to successfully send a text message in low signal?

[Guest BoyBawang]

Guys I need another advice again.

When I try to send a text message during low signal, my i780 just try it once and when it fails, it immediately report a failure to send without automatically trying again. I want it to work like my Nokia and SE phones where they try to continue sending (more than once) before giving up during low signals. Is there a way to make it persist sending after unsuccessful try?

thanks in advance
