Activating Unlocked Droid Maxx

Hello,

So I have an unlocked Droid Maxx from Verizon that I'm trying to get functional on T-Mobile.

When I put the T-Mobile SIM in I get a message that "this SIM is from an unrecognized source."

I have created an APN profile with these settings: Taking An Unlocked Phone To T-Mobile? Here Are The Settings You Need For Data | ZAGGblog

I still cannot get any connectivity to the T-Mobile network.

For about 30 seconds I saw the T-Mobile data symbol and full cell bars, but the phone was still in emergency call only mode and then it just went dead again.

Please help.

Cheers.
