Pros: Freedompop sells excellent pre-owned phones. This is my 2nd Samsung phone from them and both seemed almost fresh out of the retail box! The screen was immaculate and the edges weren't scuffed or scratched. Battery and rear plate also seem brand-new. Charging port was tight and port cover was perfect.

If you know anything about the Galaxy S5, it is an older phone, but it still holds up after all this time. The specs are just incredible for this price($140). And mine just updated to Android 6.0.1 (marshmallow) on 08Apr.
The phone is amazing quality, and I love to use it daily now.

Cons: Freedompop software and activation is pre-installed on each of their phones. I never liked FP service as Ringplus is far superior.
Even though I never wanted FP service, I had to create a FP account (each phone requires a separate account and email address for some reason) then activate it on their website. Next I had to call customer service to cancel and free up the ESN.
Once the ESN was clear, I was free to activate it on my Ringplus.net account.
After getting it on Ringplus, I used ODIN software to install stock firmware to remove the remaining FP stuff and everything was AWESOME.

Other Thoughts: It seems like a lot of hoops to jump thru, but you just have to do it once. And then you get an amazing phone for $140 in great condition. I recommend this phone, but not the FP service.

Pros: The phone itself is great. The freedom pop app is preinstalled and setting up an account and getting up and running is easy. The myfreedompop app is very useful letting you monitor your voice, text, and data usage along with changing and upgrading your plan. The camera is very good and the phone feels very fast in general. If calling over wifi the voice quality is fine.

Cons: The fingerprint scanner hardly works for me and I have turned it off. If you're not on wifi the voice quality is noticeably worse and there is quite a bit of lag. I recommend porting your old number to google voice and calling with that as google's voip quality is better, even when not on wifi. This also allows you to send any missed calls or texts to your email in case freedompops service doesn't allow it to get through. This hasn't happened to me but other users have reported it happening to them.

Pros: The phone is great. I love the fingerprint scan and all the features.

Cons: FreedomPop's service often drops and their information is somewhat misleading at times. However, it works for me. I don't use my phone too often.
