T-Mobile is so confident that you will be very satisfied with its cellular network that it will offer the new iPhones at a lower cost if you are willing to switch from a rival carrier soon.<br />And if you are not happy with the quality of the service, T-Mobile promises to give you your money back in the first month or unlock the smartphone, free of charge, after that.<br />This "special introductory pricing", as T-Mobile calls it, means Jump on Demand customers can get an iPhone 6s for as little as $20 per month, or an iPhone 6s Plus starting at $24 per month.<br />This is a launch deal, so "it won't last long".<br />For this offer, T-Mobile is relying on recent improvements it has made to its cellular network, specifically what it calls "Extended Range LTE".<br />It is Band 12 support, in the 700 MHz spectrum, which is designed to boost indoor coverage.
