Does Verizon automatically unlock phones, when their paid off?
I guess they unlock the phones after 3 months. Please check Verizon page for more details, However, Visible only ships unlocked phones.
Besides ZTE blade 3, all the phones sold by Visible are unlocked. However, Verizon may unlock the phones after 3 months of full payments.
I have never seen a paid off Verizon iPhone 8 not unlocked
