eBay

I recently acquired a cellphone that stated as "unlocked" in the description.I took my sim card out of my old device & inserted it in my new phone & it failed to even read it.Do i need to get it "unlocked" or is it a malfunction of the new phone?路

What's "Batch Processing" & why would i want it on or off?路

How exactly do i cancel a bid? someone bid on my item & then retracted it.How so?
