They are trying so hard to get customers to leave the more expensive AT&T and Verizon networks with things like "Cut your bill in half!" and "New phones delivered to your door!"
This is a foolish waste of money when they are not addressing WHY the customers are leaving in the first place. Customers are leaving by the thousands because of poor service AFTER they join. Yeah, your bill is cheaper, but when you have problems down the road, billing issues, tech support issues, etc. you will see Sprint's true colors come out.
I switched to Sprint to save money, and I definitely am saving money over Verizon, and I'm able to keep unlimited data and still upgrade phones. That is great!! But there is forum after forum online with Sprint customers' unanswered questions. For example, I am trying to help a friend enable WiFi calling on her LG G2 since in her house the Sprint signal is weak enough that she misses calls. We navigated to Sprint's own forum, and actually saw Sprint's customer care representatives answer that all tri-band LTE phones support WiFi calling. She proceeded to type instructions on how to enable it. Customers on the forum tried, but were unable to find any of the options listed in the instructions posted by the Sprint rep. FINALLY another rep responded that only the older Samsung phones were getting that support.
This is one small issue among a literal multitude of unanswered issues. Your phone is NOT going to be supported like it will be on the other larger carriers. You as a customer and a PERSON do not seem to matter to Sprint. I initially joined Sprint months ago, but because they jacked my rate up $35 higher a month than what was agreed upon and signed on a contract at the store, I cancelled my Sprint service, returned my wife's phone, and processed the return for my Note 4 - which was on pre-order and I hadn't even received yet.
Almost FOUR MONTHS LATER and after being sent to collections by SPRINT for a phone I never even received ... I finally got refunded the money I paid for the Note 4. After restocking fees other fees, and countless hours on the phone with countless Sprint reps my issues were finally mostly resolved.
If I wasn't FLAT BROKE I would not have switched to Sprint, ultimately. But I cannot afford to lose unlimited data, and I cannot afford to spend $600+ to pay for phones full price in order to keep Verizon's unlimited data, not to mention Verizon's higher monthly fees since it's an older plan.
Sprint HAS upgraded their network. My coverage in places where I spend 95% of my time is actually quite fantastic, but I don't expect Sprint to make their customer service fantastic. And that is a shame, and makes all this money and effort they're spending on their current marketing initiatives a cruel and stupid irony.
They're trying so hard to lure in new customers without doing anything to ensure that they keep the new customers long-term, not to mention caring for the customers they already have!
