t100 delivery reports

just bought a t100 for the mrs.. was on tmobile.... unlocked it with the san-tel proggy :) all fine open on all networks.... only prob is that i cant switch delivery reports on in the text msg settings... say's "not allowed service's". any ideas as she is used to having them on when tryin to contact our kids lol.. i also have a t100 and i can switch them on, my chip in her phone and nope i cant........... please help she's doing my head in

It depends on who was the original network...
Orange have the service T-Mobile dont etc...
The unlocking makes no difference it just allows you to use the sims not all the services.

I think you need to upgrade to a T108 I upgraded and now delivery reports work on orange
