[automerge]1569142085[/automerge]iPhone Upgrade Program. The iPhone Upgrade Program is available to qualified end-user customers who finance and activate an eligible iPhone with an AppleCare+ Plan, as set forth below.
...
Wireless Service Activation. The Financed iPhone requires wireless service activation on a new or existing wireless service plan with an eligible carrier under the carrier’s terms, and may be subject to an additional fee charged by your carrier.
The part numbers does not clearly differential GSM/CDMA. If you were to break each letter of the part number down, it basically specify the device such as retail unit/replacement unit, carrier, iPhone name, capacity, color and region. As stated in Apple LTE support page, GSM/CDMA differentiating models starts with A like A2161. If you go on your iPhone and go to Settings>General>About>Model Number>Tap the model number to get the AXXXX that will specify LTE models. If you go into Verizon/Sprint and AT&T/T-Mobile store, it should match what I said below:

You're just stating irrelevant facts that aren't under dispute at all. You aren't connecting the fact that when you activate your iPhone, a server at Apple looks at your serial number, decides whether you got a CDMA or GSM configuration, and locks out CDMA as appropriate.
Nothing you say is wrong here. I'm not disputing the fact that the A model numbers are identical. I'm not disputing the fact that the hardware is identical.
I'm saying there is a software CDMA lockout based on the carrier the phone was intended for. It's delivered to the phone the same way the SIM locks are delivered.
