assuming you have TEP. Hardware defects are always free repairs OR exchanges if need be. Sprint Nor Insurance will ever switch models during an exchange unless you've had 3 lemons in a 6mo period, and even that is pulling teeth. If you want a different phone, you have to go a different route to get it.
PS, w/ TEP, the only time you pay the deductible is if you Physically Damage the phone.
Just to clear up prior to him going in and expecting a phone to be exchanged....not every store has the capacity to send you out the door with a new phone same day. Most of us have to AE (Advance Exchange, basically we have to order it from a warehouse) devices.
Also keep in mind that the technician is required to try and fix the problem prior to ordering it - we have AE budgets to maintain, and if the technician can't duplicate the problem, he can't troubleshoot the problem to fix, and or declare the issue something that justifies replacement.
and finally in so far as TEP/ESRP that covers the cost of repairs and AE's, ESP is basically mail in insurance, and ONLY covers you having insurance enough to be able to file a claim with Asurion.
If you don't have insurance, or if you're running with ESP it is a flat fee of 35.00 plus tax, all parts have 30 day warranty on them etc etc.
The 100.00 deductible is, as theblizzard stated, for physically damaged phones (charging port is broken off the board, or more than two cracks larger than an inch etc) or liquid damage - and keep in mind LD doesn't mean you dropped your phone in the toilet, you can get it from taking your phone in the bathroom while you take a shower, getting caught in the rain etc. Once you have either of those two things there is NOTHING we can do outside of helping you file a claim.
switching carriers doesn't help either as Asurion seems to have a monopoly on cell phone insurance with the major carriers.
