Im looking into upgrading as I understand all the phones you can get need a tab so I would have to pay more each month until my tab is payed off ? If this is right i don't want to pay extra monthly I'd rather just pay it off I was looking a pre owned do these pre owned phones have a warranty if so how long is it? Would it be the Same warranty if I where to buy a brand new phone or would it be a bit shorter ? I'm looking at the lg g4 I had the lg g3 I loved it but the screen fades to black so it doesn't work anymore and it has no warranty. One last question can I get a phone from a koodo booth/store or do I need to get it online ? Thanks.
