currently Costco is running promotion on S9 to save $100 and further $100 cash card from costco.
if we get S9 from this offer and activate in line of one account, can this phone be used in any line of any other account of tmobile? or i t can be used in the same account where device has been activated during purchase?
The safest bet is to use the device with the line in which you activated with to get the offer. I'm not seeing the specifics of this offer, so I can't tell if you'd be able to use this device with another line on another account. Do you know if their promo mentions anything about this?
Just wanted to check in on the question Mike asked above!
