Why doesn't my dual SIM setup work?

I've been using my BLU Studio 5.5 S for work, and instead of owning a separate work Phone I thought it would be good to use this phone because of it's dual SIM management. However, when I put the two SIM cards in, one from AT&T (my own provider) and one from Verizon (work provider). Only my SIM card is recognized and I can only receive calls from that service. Any idea what's going on here?

Answer this question I have this problem too

Is this a good question?

Hey Cody,

Consult the additional links page for information on dual sim setups. Also contact your work and get permission to call Verizon on that plan and make sure everything is working on their end.
