Hello and good afternoon,
Thank you for allowing me to assist you, my name is Joe and I will be happy to assist you with your concern today.
Is the contact list saved onto an sd card by chance?
being the type of phone this is your options are limited, smart phones have access to verizon contacts saved in the verizon cloud via backup, this is not a smartphone however and unlike other carriers with sim cards this phone does not have a sim card, this pretty much means once deleted they are gone.
If you have another phone such as old phone with all the contacts on it then you can transfer them:
Otherwise if none of the above then there is really no getting the contacts back unfortunately.
Please rate my answer when ready. Bonuses are appreciated.
