Im trying to activate a S6 on my prepaid account. It takes the device serial number fine but when i try to put in the sim number it keeps telling me to call customer service. I've tried multiple sim cards from multiple sources with the same result. I know the phone is good in every respect cause I've used it before on the same account. I get bored with phones and tend to change alot. Last time i activated this phone i had to go to a verizon store and it ended up costing me $50. I'd like to save the $50 this time around and activate it myself. Any help would be appreciated.
