Used Microcell Need Help

The MicroCell has to be deactivated by the original owner in order for it to verify your AT&T post-paid cellular account and location. Support has been able, at times, to deactivate the MicroCell but it takes time because of security reasons and privacy. There is no easy and quick fix unless you know who you bought it from and ask them to deactivate.

Thanks for the info.  Unfortunately that is of little help.  I can't get in touch with the original owner.  I got my unit online. 

I'm ok with it not being quick and easy, I just want service in my apartment. 

I figured someone at AT&T could track the serial # to see who was attached, then contact them or see that they aren't with ATT anymore or something. 

I will probably have to end up calling customer service when I get off work but am trying to avoid a potential evening spent on the phone, outside of my apartment because I don't have service inside of it...

I'm afraid that's what you'll have to do.

I don't like saying this to people who have already bought used Mcells but I'll repeat it for others who may wander by this forum and are thinking it is a way to get one and save money.

I personally would not buy a used Mcell, especially online.  Unless the seller will guarantee the Mcell and allow for a return within a certain time period if it doesn't work, then I would avoid it.  They would also have to guarantee that the Mcell has been deactivated and allow for a return if that is the case.

Regardless, there is no transferable warranty for a used Mcell.  That alone would stop me from buying one regardless of the money saved.  Given the Mcell's reliability history that I've seen from monitoring this forum, a warranty is mandatory IMO.

I agree with Avedis53. You could pm CustomerCare (link in my sig) and explain your issue giving them your AT&T account info and the best way for them to contact  you. It is possible that they may be able to deactivate the account so you can register but that is no guarantee.
