I was like id imagine you who is reading this review are right now- desperately seeking a resolution to a Blacklisted phone. I am a customer of IMEI Authority and I stand behind these words like id stand behind my family... "THIS SERVICE IS THE REAL DEAL". I was skeptical but I took a chance and Victor guided me through this process step by step. He had a LOT of patience with me and as of now, im calling and using mobile data on my Galaxy S20 Ultra which 30 minutes ago, was considered unusable and only good for parting out. This service is WORTH EVERY PENNY. Dont waste your time on the cheap ones. Get one who makes sure its done and done RIGHT! Thank you Victor x 1000!!!!
