Metro PCS is offering the ZTE Blade Z Max If you port in a non T-Mobile phone number, the instant rebate $100 in store takes the price down to FREE.
I was going to get LG K20 Plus. They has new $100 port-in credit promotion, any phone less $100 will be Free (like LG K20 Plus, ZTE ZMAX PRO, LG Stylo 2 etc ). So I select the $30 plan and ZTE Blade Z Max is Free. I paid $30 for the plan only, no Tax.
You can get Samsung Galaxy J7 Prime, LG stylo 3 Plus or iPhone SE 32GB for $49 + tax and Plan fee with $100 Port-In Credit .
The Store I went to don't accept Google Voice or VOIP port-in.
