My iPhone 5S recently broke and I still have $161.75 on my tab, could I pay off my tab and buy the iPhone 6 16GB for $360 on a new tab? Or is there some way of upgrading or something? Thanks in advance!
You definitely can! Only thing to note is that on that type of tab (Tab Plus) you will need to take a tab plus plan which are a little more costly, but actually a little more reasonable than before. Take a look at your options, if the plans don't meet your needs, you can put 360$ towards the tab and pay 500$ upfront plus your old tab and get any of the plan options. If not, you can go the tap plus route, and pay 360$ upfront plus your existing tab.
Also, remember that the tab will cost you 15$ or 21$ on top of your plan to pay off your tab within 2 years.
