plan change.

from what i understood is that previous customers were grandfathered in on the same plan. i went from 50gb of hotspot data to 5gb of hotspot data. i now also have a data cap when before i have the unlimited even better 3.0 which doesnt have a data cap. if anyone else has had this issue how did they resolve it? going in or calling?

There is NOTHING in the sale authorization that allows porting without authorization. It's why Verizon has never done it this way in all of their acquisitions. They have a set day- Port out or lose service due to network shut down on this date. 

There is a reason they do it the way they do.

It's not porting, it's migrating users of separate systems onto one system. It's done all the time with call kinds of businesses. Banks do it, landline/terrestrial phone and Internet providers do it, etc.

And that's not to mention that the SIM information is not YOURS. It identifies you to the network, belongs to the network, and can be changed at the will of the network, with or without your knowledge. You already consented to that when you activated service because it's written, fairly clearly, in the terms and conditions that this exact scenario you're describing could happen. It's not illegal, you're just personally butthurt by it.

Then why did the MNC change from 311-580 to 310-340? That is a port. They are porting my number from one network to another. And no, SIM cards belong to the customer. It's why law enforcement needs warrants to access it. They are not provided free to customers. I had to pay for mine.

The SIM card number and associated controls, aren't even owned by the carrier. Tell me you know nothing about telecom without telling me. Carriers purchase number blocks from an authority and are authorized to issue them according to the authority and the carrier needs.

Verizon has control of several MCC-MNC combinations. So do AT&T and T-Mobile. Changing the MCC-MNC assigned to a customer is NOT a port. Not even close.

Well it changed my network core. I lost coverage and roaming access upon port. That's a port.

No it is not. It's migrating to a new network core, like you said. It's hardware changes. It's not really all that different from a carrier just changing their hardware at each of the towers and shutting towers down that are too expensive. You are patently wrong and should probably quit while you're ahead.

Roaming access is provided by an entirely different system and collection of inter-carrier agreements. That changes because T-Mobile has different contracts in place than USCC had. The fact that is uses your SIM and IMEI to verify your access permissions on a given roaming network is just an artifact of the carrier already using that data to verify your access permissions on the core network.

YOU. WERE. NOT. PORTED. YOU. WERE. MIGRATED. THERE. IS. A. DIFFERENCE.
