How do I configure my device for a static IP?

Question

One of my lines has a static IP.  I'd like to use that SIM in an iPhone 6s.  When I insert the SIM, it says "Could not activate cellular data network".  How can I change the APN to one of Verizon's static (i.e. mw01.vzwstatic or we01.vzwstatic).  I'm not seeing anywhere in the settings to configure.  When I was using an android phone, it was easy.

I had the something on static on 9.1. you can not change it unless you use some hack website and create a apn profile. Verizon had to change me back to dynamic ip until the problem is fixed. as soon as they turned static on my air2 said i was out of data. there is no place to change in 9.1 Verizon please get a fixed soon I need static on my ipads.
