cost of phone vs. service
Bota, how does the cost of your phone compare to the monthly cost of cellular service? In the US, the 3rd and 4th place cell companies have recently been pushing subsidized promotional leases where the iPhone 6s costs $0 to $15/month for 18 months (with a final residual value/purchase cost of about $150), depending on your trade-in. However, the promotional monthly lease rate only continues while the phone remains in service with the specific cell company.
