I have Dell Streak tablet phone was in the airplane mode and thus, could not make or receive calls. I  disabled the airplane mode and tried to make a call but it was switch to airplane mode again. I disabled it repeatedly but it will automatically be back to airplane mode again. Power off and on the phone, could not solve the problem.

I contacted Optus Technical support but coudn't resolved. They advised me to contact Dell technical support.

I then contacted Dell support (Australia), they told me they don't support Dell Streak and they advised me to contact Optus.

So I'm very fastrating that I have mobile and is not be able to make call or recieve call.

Can anyone got any suggestion to get the solution on this issue?
