Got an Android phone, a Citrine ZTE, and before I signed up for the 1year plan, I checked the IMEI, and verified that I had unlocked it.
Activated my SIM today, and my phone starts up with a 'no service' and 'this SIM is from an unknown source.'
Went into settings/mobile networks. Don't have control of 2Gvs4G, but I do have an Access Point Names selection.
Create the 'Ultra" APN and save. As long as I don't try and change the APN type, I can save, and pick. If I change the APN type, and click 'save', I exit to a blank list of APNs, and I have to recreate 'Ultra'.
Without changing the APN type to default,supl,mms, No matter how many times I restart, with or without my card, I still have no service.
I also have some more choices:
I have APN protocol, APN roaming protocol, APN enable/disable (all 3 are greyed out)
I have MVNO type (set to none, choices are none, SPN, IMSI, GID
I have MVNO value, greyed out currently.
Help, I really, really need a working phone.

Oh no, sorry to hear the device wasn't unlocked properly and you are correct - CDMA devices will not work on our network and should be GSM-network unlocked devices. Hope you'll be able to unlock the device if not, you can reference www.willmyphonework.net if purchasing a new device to double check. Once there, enter your phone’s brand and model, U.S. for country and, under “Carrier,” choose our partner company, Ultra Mobile.
