My sister gave me her old Sprint Zing.
It passes your IMEI test.
Since this was on Sprint, it should be a CDMA device. But when I start to go thru the activation, the GSM sim card I bought a while back (got it on your sale as a future replacement) shows up as a selection when entering SIM card number. I assume I should enter SIM card number that's in device ?????
Does activating (before 12-31-2016) a Netgear Zing count as 'adding a new line to my existing account' (since it is assigned a phone number) to get the $50 ting credit ????
