Did you bring your own phone to Verizon Wireless when you started your service or did you purchase a new phone from Verizon Wireless? A new phone purchased from Verizon Wireless should have come with a new SIM card. Granted that SIM card could have been bad, but in my experience that is a rare occurrence.
I can't speak to your experience at a store, but I find it help to be as calm and polite as possible even if you are frustrated with not getting your issue resolved.
The call centers are generally understaffed and underpaid while handling a high volume of calls. The prepaid customer service call center can be worse than the postpaid customer service call center. As I understand it, prepaid has the phone menus because the menus are supposed to handle the majority of the reasons one would call about their prepaid service.
If you added the mobile hotspot feature to your prepaid plan, did you verify you added funds to cover the additional costs of the hotspot feature if it wasn't included in the initial price of the plan?
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
