Sorry to hear you have the cricket att variant.
I never I repeat NEVER buy Verizon, ATT , or any subsidiaries of them due to in the usa they LOCK BOOTLOADERS ....
I use Metro TMobile or I buy from Best Buy to purchase all my phones ,noticed only Motorola, One Plus and Pixel devices not on Verizon or ATT, have unlock bootloader processes for us android enthusiasts.
PS. I have a cricket sim card..
I activated it online for 30 dollars..cheapest cricket plan,
Then went to metro corporate store and ported the number to my metro account and got this phone on metro for 19.99
If cricket would play ball on bootloader access I would switch but MetroPCS keeps me bootloader unlocked and rooted....lol
