Popular Lumia 521 is still proving difficult for Nokia and T-Mobile to keep into stock. The prepaid version of the device has again sold out and is out of stock at T-Mobile. This will be 3rd or 4th time in row that this has happened. It raises very valid questions about demand planning of the device by Nokia and T-Mobile. Perhaps, they could have handle it better!!
Currently prepaid Lumia 521 is in stock only at HSN, which now labels it “customer pick“. Sadly both Walmart and Bestbuy with best price of $129 for Lumia 521 are sold out of the device.
