Hey Everyone,
So I just purchased a second hand S6 Edge international unlocked phone. I am in Ireland and on the Three network.
What I have noticed is that the phone see's 3 different networks for three but none of them are 3G or 4G
If I search for a network on my S5 it will again see 3 networks but they are distinguished by a 3G or 4G after it.
My phone will not connect unless I drop it down to 2G only and I also noticed that under network mode I have the option of LTE/3G/2G (Auto connect) or 3G, 2G
Same menu on the S5 give me LTE/wcdma/GSM ect..
Is there an issue with this phone and it not been compatible on the Irish network?
Hope someone says no
Try install stock firmware via Odin: http://www.sammobile.com/firmwares/database/SM-G925I/
Assuming you have G925i, international means it should work on all available networks world wide, not sure why your having this issue, try install the marshmallow update if 5.1.1 is still having issues. Also check your mobile network APN setting make sure they are correct.
Updated to Marshmallow and still the same. APN seems to be all good.
My model number is SM-G925F is this not the international version?
I thought G925i Was the international.... might be wrong then. Check what frequency ranges your s6 model can use and see if it matches your countries carrier frequency. If not see if someone would swap you
925F can be used in Ireland.
If you set your mobile network, what icon do you get with mobile data enabled? G, E, H, H+, ...?
Maybe you are to far away from a tower or your tower is not equiped with 3G/4G antennas.
Info;
LTE = 4G
WCDMA, HSPDA, etc= 3G
Dropped it into my local Samsung repair center and they replaced a component.. Got a new sim and just waiting on it to activate. Hopefully fully resolved..
Thanks for the input and I'll let yous know
Ok so I'm in a really really peculiar position,
Phone is unlocked and if I put an 02 or Vodafone sim in it connects to the network and connects automatically on all bands including 4g
My sim is a three sim and if the phone will only register on the network if I manually drop it down to a 2G only connection, obviously ok for calls but not for data.
If I set it to 3G only it won't even register on the network.
Set it to auto Lte/3G/2G and again it does not even connect to the network.
SIM card has been changed and checked on another phone and the phone has been into Samsung repair center, loaded with latest firmware and tested to manufacturer requirements.
Just can't figure it out!!
Any help is appreciated
The same SIM will work on 4G on the other phone?
Is the correct APN added?
Yep sim in another phone seems to be ok.
Can't understand but I'm wondering if I contact Samsung would they replace the phone for me??
In the previous post you said Samsung already replaced a component? The best thing to do is go to your service provider first before you take it to Samsung to be sure nothing is wrong on their side.
Have been on to my service provider and they have tested two sims in the phone and both didn't work while set to Auto/Lte/3G/2G
Tested sim in another phone and it seems to be ok
Get it back to Samsung.

Don't forget to ask them to test it with a Three SIM card.

Are try to force it through the hidden menu.
*#*#4636*#*#
Should I ring Samsung ireland? Also the hidden menu is not accessible
Hidden menu didn't show up when I typed it but when I pressed the call button after it it showed a message connection problem or invalid MMI code
Samsung won't do anything as they say the phone is working perfect. My provider three won't do anything because they say the sum is good and it's not a three phone so they won't support it.
Rock and hard place come to mind.
No, not the rock. In fact, your provider is "providing their service". Believe me, I work at one. Could you reboot in Download mode and make a screenshot? Did you make the official upgrade? Seems to me the LTE/3G bands of Three and O2/Vodafone are different. Maybe wrong baseband?

How do I reboot in download mode to make a screenshot? Your idea sounds like a plan ?
https://www.youtube.com/watch?v=bii27UQYAoc
Screenshot should be attached. As for the upgrade I accepted the over the air update to marshmallow and then when I dropped the phone in to the Samsung service center they would of loaded the latest firmware ect
If this is a Baseband issue would it affect my warranty if I change it? Also would this not of been something that the Samsung service centre should of noticed?

Hi all,
First time poster, long time follower!!
I'm hoping someone can help me here because i have a real headache with my galaxy s2.
When i got it at Christmas everything was perfect. But two weeks later i suddenly lost my 3g. Phone works fine on 2g (except for the slow speed), but i contacted my carrier 3Ireland and they said everything is fine on their end. My APN is perfect, i've tried toggling airplane mode, entering codes, data package checks. You name it and i've tried it.
When i force my phone to select 3g it looses all signal and i have to restart my phone and quickly go back into settings to choose 2g or i will loose signal again.
This is the following on my phone.
Android version 2.3.5
Baseband version I9100XXKI4
Kernel Version [email protected] #2
Build number GINGERBREAD.XWKI8
I've being reading about modem/radios lately, is that just the baseband? Could that be my problem. I'm a noob at this kinda thing.I just want my 3g to come back.
All help is greatly appreciated. Look forward to hearing from you all.
Thanks.

It would be interesting to know your SGS2 is white version as well as mine.
I have to say that I have another SGS2 but old black version which is perfectly functional on the same 3 network. After playing a very long times with both phones settings, I have a feeling that the core of the problem lies in the "APN type" setting. Changing it's content affects how it connects to network. I have no deep understanding of what is happening behind the scene while changing this option, but there is a possibility that the portion of file system responsible for it somehow been damaged.
It would be great if the developers could tell us if this part of the Android file system is changed while flashing different firmware/radio, or it is persistent?

Dial *#*#4636#*#*, go to phone information and see the settings for the radio. It should be at the bottom. Google the settings for the GSM, WCDMA. Mine is currently 'GSM auto PRL'. 'WCDMA Preferred'is also a better option for 3G network.

Thank you. I fiddled with GSM, WCDMA settings as you said, but no luck.
What is even more interesting is if the network mode is set to "WCDMA only", then I'm not even able to register on 3 network. After an attempt to manually connect to 3 via "Network Operators" menu, it says "Unable to connect. Try later".
Also after connecting via WCDMA, and then reverting back to GSM, the GSM dies as well. The only solution is to restart the phone.
If it is a software bug, then I do not understand why this problem did not go away after flashing different Rom with radio.

Same problem for me in Spain...
WTF happens with this Galaxy S2.First USB voltage problem and now no 3G/HSPA connection.
Any solution, plz??
Samsung: never again
guys....carriers can't sell a device that is advertised as a 3g capable phone. Call them and spit "misleading advertising" mixing "give me a phone that I can actually use" words. You could also add "Release me from my contract, I'm moving to other 3g WORKING carrier".
They'll just freak out.

T-Mobile USA?
If yes, you're probably in a market that they have not yet re-farmed the 1900mhz frequency for HSPA+ yet. The i9100 doesn't get 1700mhz, and the majority of T-Mobile USA's network uses the AWS band, which requires both 1700 and 2100mhz to work for 3g/"4g".
Hi guys, noob here, just got my first android phone (been with blackberry till now).
I got a chinese X12 dual sim phone because i really needed only 1 phone (had to carry around 2 of them).
Phone works great, only problem is with the mobile networks. It can connect to GSM networks but it won't connect to a 3G network. The phone has 3G capabilities, 3G is enabled for the required sim, it finds the 3G network but it will not connect to it.
Sim works fine, had it in a Samsung i900 on 3G (WCDMA) - i live in Europe.
The thing that surprises me most is that the phone came with android 4.0 instead of the 2.3.6 it was advertised, could this be the problem?
Data Enabled ?! have access points ?!

yes, data is enabled on it, as for the access points it has them too (althought i am only trying to connect to the voice network, not the data network)
Tried one more thing which is wierd: the phone works ok with another 3G sim from another provider, but with the other sim it doesn't connect (but it finds the actual network). And the sim that won't connect works on my old phone (the samsung i900)
The first sim that works on 3G on my new phone is from Vodafone (and they have both GSM and WCDMA in my country), while the other sim that doesn't work is from a provider that only has 3G (for both voice and data).
Quick update:
i found out i also get an "error" : invalid IMEI for both sims - it was this way when i first got the phone...
really strange thing with this phone, in settings > about > it says android version 4.0 but when it starts it has the honeycomb logo...
would appreciate any help, if it's from the missing imei's that would be good (or bad, depending on how hard is that to fix).
You can call ##778# to get into those settings. But be careful, those can really screw up your phone if your not careful.
The only reason i can think of, is if your phone only supports certain UMTS bands, while your operator is using different ones. Check out this article: http://en.wikipedia.org/wiki/UMTS_frequency_bands.
For example, my previous phone HTS Nexus One came in two versions - one for ATT(UMTS 850/1900/2100) and another for T-Mobile(UMTS AWS/900/2100). Both were GSM, both had 3G, but 3G would not work on another operator.

phone has only WCDMA 3G network - i tried it on different carriers (on 3G and not GSM) and it works fine, connects to 3G, it just won't connect to this specific network (although it finds the network there, so i guess it has the hardware to connect to it).
could this be from the lack of the IMEI ?
FIXED !!!!
Got it fixed, the problem was with the missing IMEI codes, put them back in, works like a charm.

I recently got a New Quad-core Phone from China. it is a Dual Sim and comes with high profile specifications.
But it does not get network signal on any Sim card. it claims to be unlocked. when I introduce a Sim it find my contacts, the phone recognizes it, but no network at all is found.
have any one been here before??
none if the Sim Slots gives signal (a micro and a normal Sim slot)
I double checked and my band is supported by the phone...
please help!!:crying:
I if you do a forum search under Star S5 you'll find a number of people with the same problem. I think you're referring to the same phone. Mine works very well in Holland. One of the guys with the reception problems is from Canada.
It is a Star S5 in the documetation but Google lists it as a Z2.
Needrom.com has a couple of roms you could try. I have the latest custom one and it works great.
Miz z2 - star s5
Same phone - does not work in california usa.
Something is wrong if it works in holland but won't work in usa.
Can any one out there help?
My Carrier network is GSM 1900 and I see the phone supports GSM mode PCS1900, is that the same???

Hello,
For those with the LTE version of the Ultra iwth AT&T, how did you get LTE to work on there? I tried to use my Note 3 IMEI number but the LTE data plan won't appear on my account to choose from. The operator said that I would need to get a new SIM card that is provisioned for LTE.

The operator could be right if you are trying to use an LTE plan for the first time. The way it works is you need to put the sim card in an ATT branded LTE phone to get LTE running for the first time. You can switch phones anytime afterwards, LTE should work on any phone as long as the phone supports it. Swing by an ATT store, they will take care of it.
If you had an ATT LTE plan before, you're not supposed to do anything beside popping in the sim card. That's all I had to get LTE running on my c6806.
---------- Post added at 08:47 PM ---------- Previous post was at 08:45 PM ----------
By the way, also make sure you haven't accidentally disabled LTE on XZU. There is a toggle for LTE you can add to your notification bar shortcuts.
I just threw my sim card in and had no issues with lte. A new sim card might be needed for you.

Try doing this settings then setup guide the it will download your carrier Settings and it will automatically Change your apn.... My issue was I was being throttled down so I thought I was screwed.
Im on tmo, c6833. LTE works fine. But i have set it up by going to settings-more..-mobile networks-mobile data traffic clicked-data roaming clicked-network mode LTE preffered. After that the phone resets and lte kicked in. Hope att is the same setup. Best of luck.
I bought the handset in UK and everything works fine except I cannot get the mobile data to work. I have a good reception, the handset shows 3G but no arrows to the side of it. I have changed the APN settings to my network (Talkmobile), switched on mobile data etc. but still no mobile data, please help.
when my phone dropped to 3g the internet didn't work either here in Ireland on 3 mobile.
4g would rarely stick, just putting the phone in my pocket sent it back to 3g.
this is most likely a hardware problem not software.

Thanks, but I've never got mobile data to work at all, the APN settings are all correct and the 3G symbol appears on the screen, just no arrows next to it.
A fair few people are having the same problem, myself included.
It works better if you switch to 3g only, but sometimes that doesn't help either.
Let's all hope elephone get there act together on this, it's all very well having a great screen, CPU etc, but with no network data (& sometimes calls) it counts for nothing.

Thanks for this. In the APN settings I just changed the APN type from 'net' and 'MMS' to 'default' and this worked.
It's weird, is there some sort of learning process with this phone & network settings?
When I first got the phone it was rubbish, but as i used it more & more it got better. But then I rooted it & did a factory reset & same again. This morning I put the darksense rom on & it was still rubbish. But as the day's gone on its got a lot better - 4g & everything is working fine.
But thanks, I'll bear the APN change in mind
There are lots of APN settings to edit, I don't want to mess with what I don't know, although sometimes that's the only way. Does anyone have knowledge in this department?

This code just gives me info, can't change anything.
Do you mean *#*#3646633#*#*?
& then where to select usa?
Have a try at this:
Settings>data usage>mobile networks>network operators (will search, might take a minute)>select your operator in the list, in my case 3(4g).
For me it's been solid since, 4g a lot too.
oddly enough changing the band to USA is keeping the phone on 4g for me yet im in Ireland on 3 mobile.
had it set to Europe or Automatic before that.
lets see does it stand the test of time.

I'm definitely beginning to think this whole issue is a wrong network setting, what I did worked for me (solid all day) - post #10, & I've seen a few do this & it's worked too
after a full day it definitely fixed the issue, 4g signal is strong
cant believe they mixed up something like this.
the average novice wont have a clue what to do.
i was on the brink of flogging the phone.

Update major issue if you change the band to USA via *#*#4636#*#*.
The 4g data will work great but you can't receive or make calls unless you change it back to Europe.
How do i change the band?

Press the three dots top right at phone information
(*#*#4636#*#* -> phone information)
As far as I know Talkmobile doesn't have 4G they only offer 3G for now so no matter what you do with the APN you'll never get 4G, also with most MVNO services you will alway need to setup the APN manualy as they use someones elses network in the case of Talkmobile they use Vodafone.
