[Galaxy Note 3 General] allessence:
I haven't seen any real comparisons that actually made sense to me.. So I am posting this information up to help others that might be thinking the same thing I was..

WOW and unlocked Samsung Note 3 The advert says 4G LTE... Well, that is not the case.. AT least with about 30hrs of searching I haven't found a way to make a 9005 LTE compliant since most LTE is 700 band 4, or 1700 Band 7?.. Anyhow here's my run down or take away..

Both of the following phones are Kitkat 4.4.2 One unlocked Model ATL (Spain Vodafone) 9005 and one ATT 900.

So I Bought an unlocked Samsung Note 3 9005 (SM-N9005ZKEATL).. This was before I did the research on LTE.. I've spent numerous hours pouring over info looking for LTE and the phones antenna just don't jive with ATT's or Tmobiles LTE service.. Of course this was after I bought the phone and used if for a couple of days only to find no ATT LTE

Now I can tell you on the 9005 that with ATT's sim I was getting a consistent HSPA+ signal and the UP/down times were decent but only 3G though the phone if used in Europe would be 4GLTE from what I have read..

Since I wanted to have an informed opinion I also bought a SM-N900 from ATT to see if there really is a difference between the 2 models with LTE and such..

The 900 when in active 4G LTE if all the stars align will offer speeds of up to 35mbps or even 50mbps but this is rare since I live out in the country. (I get a 4G signal 99% of the time) And in some cases like on the highway or such downloading music it would be handy.. But for Waze, internet searches, it's over kill since you don't need the bandwidth but if you are all ready paying for it.. It's nice to have..

The best I could get with the local area on the 900 is right around 5mbps to 7mbps.. The 900 4G LTE not offering any better signal or speeds vs the 9005 on HSPA+.

I did go to Tmobile in Worcester MA and had them install a sim to see what kind of network signal would be happening in case I switched to Tmobile.. It was very sad, after sim installed the APN information was setup: (the 9005 found the network just about right away after the sim was inserted) and then all the settings were verified. The best it would do is E.. This was in the Tmobile store.. I switched back over to my ATT sim and had instant HSPA+ back in the store..

As a side note.. The Samsung Note i717 ATT model always screamed at me for a Mobile Data toggle. Since I turn the function on/off often to conserve battery life while out Cycling. What a pleasant surprise it was to find the 9005 had a toggle with all the other ones as well as a few others the 900 doesn't have so back to the 3 button scroll functions just to turn it off.. vs the 1 on the 9005.

The other nice feature I like about the 9005 is when you hit the power button it brings up Device options for: Power off, Data network mode, Airplane mode, and Restart mode.. The 900 only has Power off, airplane mode and restart mode..

Battery life on the 9005 is much better than the 900.. 5 hr trip with Waze on, Data on, and a Triplog GPS mileage tracker app on and when I got back still had 87% battery life.. Very Impressive.

Today on the 900 2.5hrs with Waze on and the battery was at 75%.

Okay onto apps: 9005 no bloatware other than the standard Google apps and factory installed Samsung apps.

900 All ATT's bloatware and then some why they continue to put this stuff on the their phones if beyond me..

ON the Note 3's you can deactivate most apps now and even some of the google apps you can lock away.. Yeah...

Other thing is Samsung Kies 3 won't read the 9005 easily vs the 900 which backed up all the info that was in the phone when I tried it.. The 9005 when connected will only backup contacts and then times out..

As for Warranty info and registering the 9005 vs the 900:

I have a user account with Samsung and it recognized I had a 9005 and listed model # and serial number but offers no information.. It does offer some tags/links for manual, software and such but when I click it I am brought to a page that just says error with no working content..

As soon as I connected the 900, Samsung site recognized it and added it to my list of registered products and also had the correct info with Warranty, downloads, Updates and the usual stuff.. When I clicked the links I was immediately brought to the proper page with working content..

I'm not one to be able to offer any insights as to performance or screen info as I'm not schooled in these things.. But performance wise they seem about the same with Beach buggy blitz the 9005 seems to move faster as I crash more vs the 900 but it simply could be a placebo effect.
