S6 Edge not finding 4G/LTE networks - Galaxy S6 Edge Q&A, Help & Troubleshooting

S6 Edge on Three in UK not switching to 4G/LTE.
Network search fails to find any 4G networks despite all four networks being found by another phone.
S6 Edge Network mode is set to LTE/WCDMA/GSM (auto connect).
Any suggestions?

I can confirm my S6 Edge definitely finds Three 4G. Do you definitely have service? Which model and CSC?

Thank you.
Yes definitely had service. Tested it yesterday at multiple locations, with another phone alongside it. S6 Edge could connect to data at H & H+ rates but no 4G/LTE. A network scan revealed that it was not finding any 4G networks, yet same scan on other phone alongside it revealed 4G from Three, O2, Vodafone and EE.
It is set in the correct mode (LTE/WCDMA/GSM) but it seems that the phone is unaware of its LTE capability.
Does anyone know if there is a status screen or service screen that will show if the 4G/LTE bands are enabled?

SOLVED:
A quick wipe of the cache and the phone is now finding 4G/LTE networks.

Just tried it and it is working thanks!

Please could you list the steps how you have wipe the cache?
I facing same issues

SOLVED - FYI I just reset network settings by going - apps/settings/backup&reset/reset network settings and restored these to default. 4g came back instantly. Hope this helps

With 2G only checked - no data

With Use "2G Only" checked I get NO data. I've been googling and testing for 4 hours.
When I uncheck "2G Only" it switches to 3g and I get data. If the 3g signal is bad it will switch to E and I will get data and if I move near the window and the signal gets better it will switch back to H. So I know Edge works fine and is in this area.
At the same location, if I check 2G Only, I get no data. Voice is fine.
I went into *#*#4636 Info and when GSM Only is selected, I press Menu, and it shows Enable Data connection but when I select it, it does nothing. The menu disappears but it acts like nothing happened.
When I boot Windows Mobile 6.5 Edge and 3G work fine.
I have to get 2G only working because the 3g is random in my condo.
FYI, I can't get MMS sending to work either. I tried port 8080, I tried with username and without, with and without passwords, with APN type and without too.
I've had the same problem on builds that have a 3g only choice (wcdma). When selecting, I get no signal, otherwise it was fine. I wonder what that is messing with.

I have the same issue too
What network are you on? TMobile I assume since you talk about Edge and GSM.
Edge is 2.75G in essence. TMobile does not have a distinct 2G signal, at least not that I am aware of. It goes G (no data), E (Edge 2.75G), 3G, and H.
So by choosing 2G only, you eliminate even E...therefore no Data.

I'm on AT&T with a Telstra phone that has 850Mhz data.
If 2.75G is Edge and HAS data, how do I select it from the *#*#4636 or from some other menu?
On Windows Mobile 6.5, when I select GSM only I still get EDGE for data. So I can have a reliable voice call and when I'm not talking I can have Edge data.

Stupid question regarding mobile network type for those on 3UK...

In settings, about phone, status what does it say for you guys on three uk under mobile network type.
Mine would say HSPDA regardless of being on 3g or H, now though it constantly displays UMTS
Is that normal? Is it because I've flashed a custom rom?
And also I've noticed my data connection changes often from 3g to H.
Lastly in network mode do you guys have it on auto or WCDMA only.
Thanks
Well it will switch to 3g(umts) when there isn't anybdata being sent/received. When you need data it switches to h(hspa) so you get the fastest speeds.
This is to save battery life, so when you check in settings your probably not pulling data.
Try downloading something then looking.
Sent from Samsung Galaxy S2 on TELUS.
Thanks for the helpful reply.
Another thing though, would it benefit me switching to wcdma only instead of auto,?

When i do a network search I only get the 2G networks. If i select 3G the signal drops.
It seems i cant enable UMTS. I m always on EDGE / 2g network.
If I use the sim in another mobile it connects normally to 3G/UMTS.
Any help how to enable it on the RAZR?
It was working 2 days ago and suddenly it stopped.
Any idea how to switch between radio bands? from the phone info i can only see USA band and nothing about Europe or other bands?
This is causing my disabled 3G, I cant connect to any 3G network (voice and data).
Help is needed please
Fix the problem? Same thing happens to me yesterday. All the same. I would appreciate help.
Sorry for my English, I am using the google translator from Spanish.
Same problem here. Anyone find a fix?
Yesterday I wrote email to Motorola, I have asked several questions ... but still have not given me solution.
I returned the device to the store after trying everything. I even changed the GSM/SIM operator and the problem wasn't solved, i can only use EDGE/2G, whenever i switch to 3G the signal dies.

For mine, the testing menu is *#*#4636#*#*
No luck yet with what you suggested, but I'm trying different combos of APNs and messing with the testing menu to see if I can get UMTS.

I've fixed my particular issue. I did an upgrade to the iPhone 4S (US AT&T), and am selling the iPhone to pay for my xt910. Apparently, when they did the upgrade, they inadvertently removed my data plan. They fixed the issue and I'm now getting full UMTS on wap.cingular.
Hopefully that will help some of you other guys having the issue. I thought it was the phone itself, but it turned out to be my plan.

US Cellular S6 Edge on Cricket

Has anyone confirmed that I would be able to use a US Cellular S6 Edge on Cricket. I have read quite a bit of info on the subject and it looks like all the CDMA versions of the phone have the appropriate band support, although I may have to root it and enable them in the service menu. Does this sound correct? Thanks for the help!!
I just bought one from eBay 2 days ago. It's a US celluar s6 edge and it's working on cricket for me. The only problem I have is that sometimes it won't let me send text messages. I have to switch airplane mode on then off and it will work. When I try to add the apn it will save but after about an hour it gets erased.
The only problem I had was not being able to text when it was on 4glte. I rooted it and set my network to wcdma preferred and now I don't have any issues. Texts, calling and data all work great

Galaxy S6 Edge SM-G925F on T-Mobile USA and LTE/Data problems

Hello. I have an SM-G925F which I bought from Telekom Macedonia and I am still using my number from there also but I am currently in the US and would like to use it on T-Mobile USA.
I know that the device supports all the same bands as the SM-G925T model.
The problem I am having is that when my phone is set to LTE/WCDMA/GSM in the Network Mode settings, I do not have any data connection at all, only when I make a call, I start to get a data connection but only 3G/H+. If I switch my setting to WCDMA/GSM, then I get a data connection at all times like normal but it still is only 3G/H+. I have tried two different APNs and different settings in the APN but I still cannot get a data connection at all times on the LTE/WCDMA/GSM setting and I cannot get LTE/4G at all.
After contacting T-Mobile, all they came up with is to try to have the same software reinstalled on my phone. Does anyone have any experience with this and can anyone help me?
Anyone?
Call Tmobile and have them input your phone's IMEI in their system. Ask for the APN settings as well. I am on the same boat and one call to ATT got me from H to 4G. Your phone will just show 4G, not LTE but you will get LTE speeds regardless.
I tried doing that too. I called T-Mobile a few times and they confirmed my IMEI number being on the account but still no luck. It's really weird..sometimes I get 3G/H+ on the "LTE/WCDMA/GSM (auto connect)" network mode setting on the phone but most of the time, I get NO DATA connection at all..only the signal bars.
Any Update
Did you finally figure it out? Is LTE working now?
