yes, they are retrievable...but at this point not from the phone, since
it will give you the sim rejected error when you put it in a phone. I
take care of this quite a bit for my customers. It generally requires
a SIM card reader or a piece of hardware (such as a Cellebrite) that
will transfer the phone numbers from the sim to another sim or phone.
There are a lot of stores (but definitely not all, as they are quite
expensive) that have these pieces of hardware. Just call a few of your
local stores. We do it free for customers that have purchased phones
from us...and we charge a small fee (generally 5 or 10 dollars) if they
are not our customer.
