| | Re: Enabling UMA on sim free handset
I am trying to activate this on an AT&T (albeit unlocked) 9700 and am unable to complete this step:
Select the SEGW certificate named T-Mobile USA, inv. Engineering and Operations CA
I have a T-Mobile 9780 (also unlocked) and I have placed the T-Mobile SIM card in the 9700 but am unable to get the needed SEGW Certificate.
Is there a way I can use one of the utility programs to transfer the certificate as I've done with .cod files in the past? Has anyone found another option with an AT&T branded phone? Because the 3G frequencies are different on the networks this option would be a nice addition to using my AT&T phones with my T-Mobile SIM without being restricted to EDGE speeds.
