The FCC rules the following:
e)Handset locking prohibited. No licensee may disable features on handsets it provides to customers, to the extent such features are compliant with the licensee’s standards pursuant to paragraph (b)of this section, nor configure handsets it provides to prohibit use of such handsets on other providers’ networks.
Verizon as always with it's greediness.
This rule won’t be applied since the FCC chairman is Ajit Pai, who was a lobbyist for Verizon in the past.
