No 4G connection - Galaxy Note II Q&A, Help & Troubleshooting

Hi,
I bought my N7105 from france, I moved to Dubai later on. Carrier supports 4G (du) but my phone mostly connects to H+, rarely 3G but never 4G.
I'm running a rooted official firmware 4.1.2, I searched on xda for same with issue it was there on Vodafone/AT&T in US and most solutions were a change in qualcomm's something!
In dubai they have GT N7100 but N7105 is not sold anywhere in middle east for some reason.
Please spare me the "buy a GT N7100" comments!
Would be great if have any suggestions.
Thanks.

Supporting 4G doesn't mean you'll GET 4G. They have to use the same frequency bands as supported by your device or it won't work.

According to 4g-map.info uae supports 1800 anf 2600 mhz so there is no reason why the n7105 wouldnt be comptible. What baseband do you have? Im running h3g nedma1 and I can see all three currently active 4g networks in the uk. So maybe try flashing that baseband check out the n7105 flashable modem collection in n7105 android development

Also check with your carrier. You might need a special APN for 4G access, you might need your IMEI added to an approved list.
There's much more to it than just the handsets physical capabilities.

Yes.. You have to check whether you device support the network frequency or not.
I am from Malaysia. Study in US currently. I am using my N7100. And T-mobile network.
T-Mobile doesnt support 1900mhz frequency (except san jose, san francisco and certain area). When i go out of these area, i only get 2G in my international version note 2. So, do do some research and get a carrier than has your device frequency. You can get the answer from Wiki.

Ask from your operator what frequency they are using for 4G. I think Note II supports 800, 900,1800 and 2600mhz for 4G. If ur operator uses other frequency which is not supported by Note2, then u wont get 4G on your device. In my operator, they use 1800mhz for 4G, so I can use 4G on my device.

If you look at my previous post you will see I have already told him what frequencies they use in uae. Plus the fact that the n7105 supports these frequencies

[R&D] my T-Mobile Samsung Galaxy S II shows LTE bands

Hey guys i bought the Samsung Galaxy S II from T-Mobile thinking that has HSPA+ bands I, IV and V.. like the box and website says.
Here we use HSPA+ band V (850) so, i inserted my sim card but i only pick 3G bands ( HSDPA )
Checking the bands that the phone has using *#2263# i noticed that i have WCDMA, GSM but also i have LTE bands ...
I never heard that T-Mobile Galaxy S II has LTE bands..
Any ideas why it says LTE instead of HSPA+?
YES, I WAS RIGHT! Samsung was to lazy to change the modem between the skyrocket and the T-Mo SGSII, so if you flashed one of our modems, you'd technically have a functional LTE radio.
Wow, this is crazy!

You'd have to flash a Skyrocket radio, because when I was using a T-Mobile radio, it wouldn't connect to LTE.
But that means, if I'm right, the Skyrocket and T-Mo SGS II have support for 850, 900, 1700, 1900, and 2100 HSPA+.... that's a pentaband phone.
****. YES.
Go ahead and try it folks.

Your talking about the post merger agreement right? It just may... and those of us on T-Mobile may be able to hijack Lte once the agreements are in place lol.
Its cool how there are so many similarities between the two phones. They are almost identical which is great for developement.

Yeah, but I don't think AT&T would allow another carrier to roam on a very new LTE network, especially when they don't even have 10% of their own customers on the network.
And it's really cool, because they are the same phone. xD
Although, I don't know why our accelerometer is flipped.

Could be, but with the short amount of time between release of the 2 phones, Samsung must have developed 2 phones, same hardware, flipped the accelerometer in one, and branded one AT&T, and the other T-Mobile.
Gotta say, that's a great way to save with development.

maybe you are right. i just bought this phone so, its probably the new version.. however.. here in peru where i am at, we use HSPA+ 850 but i cant pick that signal .. only 3G ( HSDPA ).. so means, TMO SGS II is penta 3G band but only One band HSPA+ ?

No, try this.
Go to the skyrocket forums, find the radio thread, and flash one of those modems.
If I'm right, it should kick on the 850MHz portion of the radio

Even if u have hspa+ it will say 3g on this phone because ur carrier may only be supporting 21mbps and not 42. You probably are getting hspa+ speeds but ur phone just shows it as 3g

Theoretically it should work. Lol, an ode to the original vibrant, sometimes their laziness pays off! I've noticed the sensation has LTE mentioned also. Haven't dug if it but I wonder if it actuall does support LTE ? If I'm not mistaken LTE uses AWS protocol right?

Is the international GS3/quad core compatible with T-Mobile?

I assume the quad core gs3 is GSM? Will it work with T-Mobile 4G HSPA+? My friend is on T-Mobile and is planning to get the gs3 off contact. He wanted me to find out if T-Mobile 4G will work with the quad core version or should he just buy the T-Mobile version instead.

It will work but you will be stuck on Edge.
I'd check what frequencies it has. I'm using a T-Mobile version on at&t and get 4g data. If the international version has T-Mobile's frequencies then it should work.

Are you getting 4g lte or hspa? I don't think t-mobile s3 can do lte

Would this work?
Tmobile uses Band (frequency): 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band V (850)
Device Additional Information tab on that site says "Service 900, 1800, 1900, 850, 3g 2100"
But at the top of the page it says "Band:GSM 850/900/1800/1900"
T-Mobile UMTS/HSPA+ (3G/4G) mostly runs off 1700/2100 and the international model i9300 does not support the frequency we use. The quad band GSM/EDGE will work (and therefore voice/text and slow internets).
AT&T uses a more normal 850/1900 for everything but LTE, making them more "Normal" along with our Canadian neighbors.
T-Mobile is weird :-o.
If you've got access to any make of GSM based + unlocked iPhone, stick your T-Mobile SIM in it and see what speed you can get. An unlocked AT&T phone may work for testing also. We're supposed to be getting better coverage in this kinda frequency range for that but it will likely be a long time before we get sufficient coverage to enjoy a i9300.
Well put. It will be a long time before we see decent coverage for AT&T/UK phones.

[Q] 4G LTE 1800 mhz

Hey guys,
So I know this may be a noob question but I bought my Samsung Galaxy Note II N7100 yesterday in Italy. I know that Italy is getting 4G/LTE in 800/1800/2600 Frequencies. My N7100 accepts the 1800 mhz GSM frequency.
Does that mean I will be able to access the 4G?
If not, can I do something? Flash a radio?
If there is no solution with my current phone, ill need to get another phone and spend another 699 eur.
I know many say you need the Note II LTE but it will be on 700 and 2100, not the ones offered in Italy.
My friend has the same issue with his brand new SIII.
Ideas? Anyone help?
2G, 3G and 4G (LTE) can use various freqs in different regions. Sometimes they even share the same freq. A 1800Mhz 3G does not mean that 1800Mhz 4G will work. It's different a modem by hardware and software in the phone.

Your N7100 doesn't have an LTE radio, so it is never going to work on LTE.

That depends on the LTE bands that the device supports. You are looking for LTE band 3, which is 1800MHz.

The official LTE versions of the Note 2 and S3 from Hong Kong are tri-band LTE models. Running LTE bands 900mhz 1800mhz and 2600 mhz. So as long as your carrier has LTE in any of those bands it will work. The iphone 5 is only 1800mhz. I am currently using 4G on 1800 and 2600mhz as my carrier runs both bands.

Can N7105 use Canada LTE?

Hi All,
I am using a N7105 on Bell Canada network. Seem my phone only max. on HSPA+ not LTE. Base on I am reading some information from internet. Bell is using 1700/2100/2600 Mhz for LTE. My phone only able pick up LTE 800/1800/2600 Mhz. My question is shouldn't my phone work on Bell LTE network on 2600 Mhz?? Also does anyone out there use N7105 and able to use LTE on Rogers/Bell/Telus???
Thanks
PC
wow really no one use N7105 in Canada???
It will work but generally performance would be poor inside buildings or in areas of interference, due to having only one compatible band instead of two.

This is stupid they don't follow the other country
So which model name/number is the Canadian Bell one? I'm thinking of buying one in Calgary, but I wanted to monitor ROM development before I got one, so which forum should I follow for the Canadian one? I just guessed it was an N7105, but apparently it's not!
Edit: Nevermind, found it on Wikipedia. It's SGH-i317M and seems roughly same as AT&T, I guess I'll go to that forum!
Although I don't know anyone that has a N7105 on LTE in Canada, I've seen people use LTE with a I9305 (with the same LTE bands as the N7105) in Vancouver at least, so technically your phone should work. It may be that your area doesn't have the 2600Mhz spectrum.

Ah so i called Bell they told me they have 2600 Mhz but you never know. Cause Bell tech. support sucks
N7105 supports 2600 mhz radio frequency, but a respective modem file need to be flashed for it to work on LTE network.
I had Note LTE i717 which supported 1700mhz lte of Rogers, and yes it worked with wind and T-mobile network using 1700 mhz frequency only after flashing tmobile modem.

Yeah me too hate .....I was in long dilemma to buy N7105 , but when I found this then i just bought it outright from Rogers.
Also to let you know that even after flashing 2600mhz to work as lte radio, you will only get lte in 2600mhz lte available areas only, bcoz lte in NA fluctuates many frequencies from 700/1700/1900/2100/2600.

I just bought a N7105 international version from Hong Kong and yes it work on Rogers here in Vancouver. Make sure you get a LTE compatible SIM card. My old SIM card did not compatible with LTE so I only got H+ or 3G. Now I changed and I am on 4G.
The reception is only 2 bars most of the time though. Sometime I got 4 bars. I tried data speed using Speedtest.net and still got at max 52Mbps DOWN and 34Mbps UP even I am at 2 bars so I guess it isn't too bad.

Sorry, but it's not going to work with this phone.
Orange Dominicana uses the 900 band frequency for 3g (WCDMA). On this phone that band is locked for being used with 2g (GSM). That's why you're getting Edge.
Unfortunately, the T-Mobile version of this phone also locked the 900 band for GSM. That means the NV data hack won't work for you either.
Sorry. Hope that explains it, and I hope they at least launch LTE service on a compatible band for you.
