[Q] Lookingto move to the Note 2 and after clarification

Hi All. Long time since I’ve posted but looking at getting a note 2 tomorrow.
Now I live in Australia and on the Optus network but using a cheap provider that at the moment only uses their 3G network.
At the moment I have a sim card setupfor the 3G network.,
At the moment Vaya don’t have access to the Optus 4G network (1800MHz frequency) but it is gonna happen.
Can I buy a LTE version and use my current sim and run on the 3G (H+ even) using my existing sim card and the 4G note 2?
Then when Vaya release their 4G plans I can grab a 4G sim (or is 4G just account and phone dependant??) and away I go?
I believe it shouldn’t be a problem as the phone still operates on the 3G network as if I bought a N7100 if 4G is not enabled. But it will use more power just having that chip sitting in there.

yes, it will work.
it will only work in 4g if a 4g network is supported from your carrier. otherwise it will revert to the fastest network from your carrier that is supported by the device, which in most cases is hsdpa.

Thanks for your reply.
Now I've been searching everywhere for good analysis on the 3G and 4G battery comparison but there isn't much out there but personal thoughts. Well there is more on the S3 so maybe that is a good guideline.
So the 4G version with LTE turned on can only achieve half the screen on time of the 3G version. Wow that terrible. With LTE off it last about 7-8 hours screen time rather than closer to 10 hours to the 3 version.
Has anyone got some good links that compare the battery life between the two models? I can live with turning 4G off most of the time if it doesn't drain too much but I don't need the speed if it has a big toll on the battery life even with LTE turned off.

LG G4 VS986 on T-Mobile LTE problem

Issue:
Phone will not stay locked on LTE in Global or LTE/UMTS/GSM mode. When in Global or LTE/UMTS/GSM mode and LTE does connect, it's momentarily and when trying to run a speed test or open a webpage, it quickly disconnects and connects to HSDPA. If switched to LTE/CDMA signal locks in great and data speeds are great however voice services are not available. Any thoughts or advice is welcomed. Thanks ahead of time!
Facts:
Phone: VS986
Android Version: 5.1
Build: LMY47D
Soft Version: VS98611A
APN: T-Mobile Fast apn (fast.t-mobile.com)
Strong LTE area
*#*#4636#*#* Not available on LG G4
Radio Swither Not available on LG G4
Rooted
Xposed installed
Gravity Box installed (no change when using smart radio features)
G3 Tweakbox installed but module will not register with Xposed Framework (I know it was along shot)

What band LTE are you connecting to? I found that here on band 2, I will connect at first, but then it switches back to edge. Seems fine in a band 4 LTE area though.

I'm in the Raleigh NC area. According to LTE Discovery i'm using Band 4. and I also experience the same. A brief connection while in global or LTE/UMTS/GSM mode then it falls back to HSPA.

I haven't found LTE Discovery to report the band correctly, at least in my case. It would say I'm on band 4 on my Moto X, but when using a band 4 only device I would only get Edge, but when I go in a confirmed band 4 area it works fine. From what I've found, most 2G > LTE sites were converted to band 2 LTE. Although since you get HSPA the chances of it actually being on band 4 are higher.

I'm fairly certain this is a Band 4 area. The latest T-Mobile maps are pretty good about pointing out Band 2 areas. I've since sold the phone and acquired a iPhone 6 Plus which I'm looking to sell to replace it with an international G4 or T-Mobile G4. I was pretty impressed with that phone. If I had to rank my favorites, it's number 2. Nexus 5 is still king of the hill for me. There wasn't a better phone out when it was release for a better price.

did you ever figure this out? samething is happening to me

Unfortunately I didn't. I sold it and bought one for T-Mobile...... Which I just sold about 3 hours ago.

So I tested it out again, and in a band 2 area when I boot up my phone with a T-Mobile SIM, I get LTE for several seconds then it cuts back over to 2G.
Now that there is a new software update for the G4, I wonder if this is anymore reliable. Anyone who took the OTA update in the past few days, can you let us know if it's any better?

Been there, done that...wanted to switch over to T-Mobile, but unfortunately, the VS986 only works with two of their three LTE bands, as you know, and it seems everywhere I went, they were using the one the phone doesn't receive (I'm in southern California, for what it's worth, but tested it on a freeway run up the I-5 to the central part of the state - only got 4G-LTE in a few places). Wound up going back to Verizon

I'm getting the exact same results in Burlington, VT (T-Mobile band 2 market). I first have to manually select T-Mobile (defaults to roaming on AT&T HSPA+) then LTE works for less than a minute (LTE Discovery says band 4) and then I lose signal when I get signal again, I only have edge. It does this constantly and is really annoying.

Aww, bummer. I was thinking about switching to T-Mobile, but looks like that is not a viable option? So no one has been able to successfully use the phone on T-Mobile, even after enabling bands 2 and 4 only?
This whole plethora of LTE bands, where each provider does its own crap is such a mess, is just serves to lock in customers, since switching phones is expensive. Government should mandate that all phones can work on all US LTE bands, the technology exists.

I am on the same boat. Everything works on my VS986 on t-mobile network. but I cannot get the LTE to work properly. LTE discovery shows band 4 (not sure if correct though)

My VRZ LG G4 shows that it has Band 2, 4, 5, and 13. I tried enabling 2 & 4 only, 4 only, 2 only, 2&4&13 only but with no success.
What is interesting is I am coming from VRZ LG G3 and LTE was just fine and never had an issue.
I looked at the VRZ LG G3 LTE bands and I see Band 3,4, and 13 enabled. It did not even have band 2.

More testing:
When I switched the Network Mode to LTE/CDMA I get constant 4G-LTE & internet is working but my phone cannot place and receive phone calls.
with LTE/CDMA I see 4G at 100dBm and 1X at 120dBm

Interesting, almost sounds like a bug in the LTE/GSM mode.
I assume when you switch to global mode, voice works but only HSPA, right?

I think since someone reported before that this used to work the G3, it sounds like a bug to me. I guess we can hope and pray that this will work in future releases, but there is no guarantee of course. Not sure what complaining to Verizon will do, since they are probably not very interested in you using T-Mobile. Of course, you can always wrap the complaint into something like you are using the phone in a different country on vacation and it doesn't work. Maybe a complaint to the FTC could work too, since it sounds like Verizon is required to have their phones unlocked for use on other networks based on some settlement.

I am tempted to try the guide in here to add more LTE bands:

While some testers said the LTE bands are limited by hardware others reported some success modifying the software. Any thoughts?

LTE everywhere EXCEPT New York City; Verizon says Buy a new phone. What?

I'm using a Toro Nexus that was recently given to me by a coworker and it works great everywhere except where I live and work. It simply refuses to connect to LTE within NYC, where it stays on 3G. As soon as I get outside of the city it has great LTE connectivity which allows me to make use of my unlimited data plan.
I started out stock, then flashed to 4.4, 5.1 and even tried the latest experimental ROMs without any change. Verizon did whatever testing they do on their end and said that, because of the buildings in NYC, the phone is incapable of receiving LTE. That sounded like a crock of crap to me so, using a few of my remaining grey cells, I put my sim card into my wife's Galaxy Note 3 and, voila! no more LTE.
So I'm getting ready to make an angry call to Verizon when I think, why not try the wife's sim in my Toro. Result: 3G only. Pop it back into the Note: LTE.
Dang! Can anyone offer some insight as to what is going on?
Thanks for any help.

When you go to Settings, what is the signal strength reported?
I have a ex-VZW GNex (toro) that I have moved to Tracfone; I have every reason to believe that Tracfone uses (mostly) T-Mobile towers in my area, and I have ALWAYS had signal-strength issues via T-M towers. (Tracfone has towers assigned to it on a zip-code basis, and it's not always T-Mobile; in some zip codes, Tracfone uses VZW towers.) It could well BE tower-siting issues plaguing VZW in the Apple - which is, amazingly, smack dab in VZW's turf.
I wish there was a way to determine exactly WHICH tower that a phone aims at while on the move - so you can find "bum towers".

LTE on T-Mobile not working AT&T working

So I got my pixel xl from Google today. It works but I am on T-Mobile and it will not connect to LTE band 4 or 12 which are in my area. I have an ATT SIM for my work which I popped in and it works fine. That said without driving around Atlanta to try to find B2 I cannot tell if it is T-Mobile or the phone. Is anyone else on T-Mobile getting LTE connection at all?
So news today I can connect to LTE. Yesterday when I got the SIM in using *#*#4636#*#* I would get zero reception forcing LTE only. The phone would only connect to UMTS/HSPAP. Today after several restarts and calling T-Mobile and Google support it is now working. Here is what I did.
First Google is saying the update is supposed to affect LTE connecting issues.
Second make sure your SIM is properly registered with your provider. They should elevate the issue to higher tech support to have them look into it. This takes up to 24 hours.
Third go to your dialer do the *#*4636#*#*, go to phone info and change the preferred network type to LTE/UMTS or LTE/WCDMA (I haven't seen a difference between them). (This info is in other threads) Then restart your phone.
The problem seems to be how the phone determines what bands the network provider uses. It defaults to CDMA as the voice connection. For me this meant the phone was always connecting to UMTS only. It seems the firmware has some kind of default setting when it senses an error out the gate. The APN settings and preferred network settings needed to be updated and the phone restarted for it all to work. I now connect to band 4 LTE in my area. I hope this helps others.

I am also getting slow data speeds on my pixel XL connected to t mobile

My XL seems to get pretty consistent LTE service and good speed on T-Mobile.

Google "Pixel LTE band 4 issue"

Weird. I'm getting pretty awesome Band 4 coverage in So. Cal. I also get Band 12 here, but Band 4 is what my phone tends to be connected to, which is fine since it tends to be significantly faster.

I'm in Oklahoma on t mobile getting slow connection compared to my friends. They each have a galaxy s6 edge and get between 70-80 MBs down sitting right next to me. I'm getting 14 MBs down. I just left sprint today for slow connection. Hoping to find a way to get this resolved ASAP.

I only experience the issue in downtown Toronto area and I contacted my carrier, Telus, in Canada. They confirmed that network signal in such area is mainly LTE band 4...

Just an FYI for those with the same issue. Google has asked for my shipping address after contacting them about the issue.

Thanks. I changed mine to LTE/WCDMA. Will know how it goes next week.

All seems to be working on my end.

I was having delays in mms being sent. I was using the default APN. About a week ago I changed the APN to the one recommended by T-Mobile. Mms sends instantly now just about. I don't think it's effected much on LTE but I didn't have problems before. Make sure your on the proper APN

I sure hope there isnt a recall..My XL hasnt even shipped yet and im on Tmo

I spoke with a t-mobile rep yesterday who helped me get my issue resolved. My main apn was set up incorrectly. Now I am connected to LTE and not just hspa+. I get generally good speeds most everywhere and I have tower right by my house that must go fairly unused.

Question Cannot Connect to 3G/WCDMA

My 6 Pro (unlocked, rooted, January update) is unable to connect to my carrier's 3G network. My carrier is Xfinity Mobile (uses Verizon's network) and selecting 3G in settings or dialing *#*#4636#*#* and choosing WCDMA only, GSM/WCDMA preferred, etc results in my mobile connection being dropped. I can make and receive calls/texts just fine, and no problems connecting to their LTE or 5G networks. I am using the physical SIM from my old Pixel 3 XL, which had no problems connecting to their 3G network. Are there any fellow Pixel 6 Pro owners out there using Xfinity Mobile or Verizon as their carrier, and if so can you connect to 3G?

I just can tell you what happened in Germany, Operators disabled 3g networks. Maybe the same happens for you now

Aren't they in the process of killing off 3G, especially cdma? Very old tech.

I sure hope that's not what's happening, at least not until LTE coverage is on the same level as 3G. It just seems odd that 3G would be working fine one moment on my 3 XL (I only used 3G on it), then suddenly quit a few minutes later after transferring my SIM to my 6 Pro and getting it set up.

Where are you where LTE coverage isn't good? LTE is starting to be replaced by 5G and LTE is at least 7 or 8 years old by now. Do you live in a rural area?
The 3G Network Shutdown May Disable Your Phone (and More)
Mobile carriers are shutting down their 3G wireless networks to make room for new technology, but this change can have a big impact for anyone on older devices. Starting in 2022, companies like Verizon, AT&T and T-Mobile will phase out the older wireless network to accommodate expansion of 5G...

3G CDMA Network Shut off date set for December 31, 2022
We will turn off the last of the 3G CDMA network on December 31, 2022. Customers who still have a 3G device will continue to be strongly encouraged to make a change now.

I found both of those articles. And according to the second, Verizon is shutting down it's cdma network effective December 31, 2022.

The small ski resorts on the east coast that I go to aren't too far from civilization. My 3 XL had no problems picking up 3G at these places.

Do you know if those towers are still doing 3g or they switched them to another frequency? I haven't been on 3g except when traveling in Europe.

Xfinity Mobile's 3G is not GSM/WCDMA but CDMA/EvDo because they're using the Verizon network. That's probably why it's not working. Try using that setting.

I still need to contact my carrier and ask if/where they've started disabling 3G. I would not be shocked if they've started shutting it down near my house, but I would be surprised if the towers near the ski resorts were not still doing 3G. Driving through the small rural towns on the way to the resort is like going back in time 50-100 years. These areas seem like they're last on the list to get any form of infrastructure updates.

Still no luck. I suspect Verizon has started disabling their 3G network in my area, or uses a frequency not supported by this device.

Yeah it should definitely be supported by the modem from the specs I've seen but it's probably being activated as CDMAless now that I think about it because there was an issue early on where chat functions didn't work right unless it was activated that way. There was a whole big uproar on reddit about it with the 5a and then it happened again with the 6/6 Pro.
