Complaint / review text:
I switched from AT&T to Sprint because I lost my phone and was not due for an upgrade. When comparing plans, I determined that I would save almost $10/month by moving to Sprint. If I'd known the huge difference I would see in coverage, I would gladly have paid the additional $10 with AT&T.
I live in an urban area and I find my phone with one bar of 3G signal the majority of the time. That is not sufficient for making calls, sending texts and certainly not for using data. My phone will go from having 4 bars of LTE to zero bars when I haven't moved or done anything with my phone. I send iMessages that fail to be sent at least 30% of the time and have to be resent as text messages. I never once had that happen while I was on AT&T.
The other feature I didn't realize I would be losing was the ability to use data while making phone calls. I use my phone while traveling for business. I regularly need to be on a phone call and reviewing information in an email (on my phone). That is a feature I took for granted on AT&T is not possible on a CDMA network.
Sprint customer service is quick to suggest that it is the hardware. It isn't the hardware. I have friends on Sprint that report the same experiences.
I regret making the change to Sprint and advise others considering the switch to reconsider.
