Whats the correct way to swap an iphone 6/6plus for another iphone 6/6plus? Ive heard you should switch sims, you shouldnt and can just switch phones and take care of the swap on myverizon or in store. Whats the best/safest way? Is there any possible issues i could run into by doing a phone swap with someone ? I bought my phone outright on new 2 year contract. Any swapping horror stories?
