Phone repaired, now can't connect to 3g

Hey guys,
So i broke my Xperia Z (C6603) screen 2 weeks ago and just got it back from my insurance company a few days ago.
They somehow unlocked my unlockable bootloader and also sim unlocked the phone. I was not disappointed with this
But, i can't connect to any 3G networks since getting my phone. And since my provider only supplies 3G and not 2G, i'm screwed.
I've factory reset, flashed various stock roms, 244, 423 and also flashed CM10.1 and CM10.2. No luck! I figured one would have a baseband that worked properly?
Everything else works fine, wifi, calls, nfc etc. But when i go into *#*#4636#*#* and try to set the preferred network type, i can't select LTE etc, it just defaults back to WCDMA. Also i have no option for LTE in the mobile settings network type (i did previously). Only WCDMA only, GSM only or WCDMA (preferred)/GSM. The last one should work, but still can't connect to 3G networks. Every time i try, it tells me "could not connect to the selected network, check your sim, blah blah". But it connects to the 2G variant of that network just fine.
My APN settings are fine, as i copied them from my HTC One on the same network. And the imei isn't blocked according to my provider.
I have tried another sim and this sim in another phone, so there is nothing wrong with my sim cards. And i doubt there's anything wrong with the sim card slot, since 2G wouldn't even work then. I'm on Three UK and have phoned them for help, but they were useless and fobbed me off to my insurance company.
Any ideas? I'm pretty much out of them

The fact that they unlocked a locked bootloader and SIM unlocked the phone sounds a bit dodgy to me.
You could try downloading the APN settings, go to Settings>Xperia>Internet settings.

Yeah i was thinking that myself, and have read reports of them sending people replacement phones with blocked imei's etc (stolen phones).
Think i'll be sending it back to them. The internet settings didn't work, but thanks for the suggestion

Yeah probably a good idea, get them to explain why they had to unlock the bl and SIM lock in order to replace the screen!

How do you find your signal? Obviously having no 2G network is, in some cases, a disadvantage.
I only ask as on my HTC One S my signal was fine all the time, now with my Z I find my signal patchy and it takes a while to find any.
Oh and I wonder, does your My3 app work? Mines not working anymore, it always thinks I'm on wifi so won't open any payment pages.

My signal on the Z was always great when it worked. On my HTC One it's not so good. The three app won't work on my Z, since i obviously have no data connection at the minute. But i never had any issues with it.

[Q] Help...10.4.B.0.569 (Swiss) will not connect to 4g

Hello guys im pretty new to this fourm so if theres any rules i violated in this post please excuse me.
My problem occured when i flashed my sony Xperia z T-Mobile branded phone. It had 4.2.2 t-mobile firmware on it so i flashed to 10.4.B.0.569 (swiss) ch ftf and everything was running fine until i noticed that it wasn't connecting to 4g...Only 3g but on the t-mobile firmware it connects to 4g just fine (i reflashed it just to make sure) andi reflashed back to 10.4.B.0.569 and it still said 3g i tryed *#*#4636#*#* and messed with the newwork settings a bit like some other treads recommended and none of then changed it to 4g i even changed the APN because it was set to egc.Tmobile.com (which is 3g service and below) so i set it to fast.tmobile.com (the 4g/lte service) i changed it to everything the tmobile firmware apn said and it still didnt go to 4g it just says at 3g i rebooted my phone and still...no luck it just says 3g. Please i need help to get my 4g back i really like the UI in 4.3

Yea i tried that but i'm still getting 3G like i would get 4G with the T-mobile firmware...Could my phone be reading the 4g connection as 3G?

I am not sure. I flashed the 4.3 (generic firmware) on my xperia z too. it was originally on 4.2.2 and didnt have the 4.3 update ready yet from Telstra (Australia). I didn't have the LTE so I flashed basebands from Xperia ZL from Rogers and i got the LTE. I tried flashing the Bell xperia Z basebands that didnt work at all. so I dont know. sorry

Here are the APN's that I use, and everything works as it should - http://forum.xda-developers.com/showthread.php?t=2236735. I've never flashed anything other then what the ROM(s) instructions say - and as always it's best to start clean. Enter as it appears on that thread, select it, and reboot. Not trying to state the obvious or insult you, but also make sure you select "LTE (preferred)/WCDMA/GSM" for network mode in settings.
What I've learned browsing other threads about 4G (or HSPA+) is that it only kicks on when there is data to transfer, so if you are not uploading/downloading then it will most likely show as 3G or maybe nothing at all in you status bar, but should change once you launch an app/service that uses data. It will remain 3G if only using voice.
I will try and confirm this, but where I live it switches to LTE rather quickly. I have noticed a time or two where my friends 4G only phone has it and mine does as well. Noticed yesterday where H+ kicked in when loading a podcast, and when it was done the H+ disappeared.
Hope this helps.

Yes. I talked with a t-mobile rep yesterday and though I didn't have 100% confidence in his explanation, what he said basically lines up with everything else I've read. Check this if you're still curious - http://www.androidauthority.com/hspa-vs-lte-which-one-is-better-78120/

Are you talking about under Mobile Networks » Service Providers? This is what I see, and it actually had the 2G one selected, this is the first time I've actually ever opened that option.

Camera quality for me is just fine. I've taken a lot of pictures since switching to 4.3, and they all look fine to me with the exception of those in low light, but that's pretty much any phone.

If your provider enables lte for you and your device supports it, you're ready to go.

Settings > Wireless & networks > More > Mobile Networks > Network Mode
Mines on 3 UK, but it's unbranded and unlocked.
3 have said that they will send out an ota update to enable 4G on their handsets.
There are a few cities already enabled, so if you can get somewhere that's already on, you might be able to test your handset.

SM-N950W : Mobile Data not working.

Hello,
My note 8 cannot connect to mobile data. Whenever I activate it, nothing happens I don't get any mobile data signal what so ever. I also checked the APN's configuration with my Mobile carrier and they were unable to solve it.
It should be noted that my note 8 has a stock Canadian firmware and I am using in Morocco with a Moroccan sim card

did you check with your morocco sim does include data from your plan? Also which carrier are you using in Moroccan? it could be either your plan doesn't include data plan or the carrier doesn't have the UMT/LTE band for your note 8

Yes, I still have around 1gig of data available and My plan includes data.
My service provider is INWI and they do have LTE band since The same sim card worked on my previous J5 2016 normally.
I forgot to mention that, After activating mobile data and roaming, I checked the sim status in the setting where I found that Mobile network state is DISCONNECTED and Roaming is not running.

Can you test if you can make call or text? if so, i will suggest double check the apn. I checked your carrier in Morocco , you should be able to get HSPA data connection in Canadian Version Note 8(N950W) unless you select (LTE ONLY).

I can confirm that I can make phone calls and send texts without a problem.
I checked all options and none worked .
As for the apn, the configuration message was sent to me by my service provider itself.
I performed a factory reset that didn't help too.

Since you can make the call, I don't think it is something wrong with the phone. I checked there's only 1 hspa band and none for lte available for note 8 from your carrier. I guess either double check with the carrier for the apn or maybe the phone just can't pick the b1 hspa signal from your location.

I won't mind HSPA since there's not much difference between LTE and HSPA in Morocco. I doubled checked with my carrier today and they told me that I have to wait for 48H for them to look into the issue.
The weird thing is when I used an app called LTE Discovery I found that I do have a signal for LTE band 3 yet I have no internet.
It is mostly the service provider's fault, I think.

They might be similar to AT &T where they need to recognize the device IMEI number before allowing full data access onto their Network.

I checked with my service provider. Unfortunately, they don't need to recognize the IMEI number.
They tried to shift the blame to my phone saying that I might have a faulty device. It doesn't make any sense.

First thing I'd do is research and see if it's true what your service provider told you. It might not be. Second use another sim from another network in your device. Third borrow someone else's IMWI sim and use it in the note 8. Also check APN again.
Did the phone receive 4G or LTE prior to coming to Morocco with the same device?
I also don't fully understand on your earlier post about the phone status not being roaming. It shouldn't be roaming status if using a local sim card.

I still haven't tried another INWI nor another Moroccan sim card.
I have no idea whether or not it received 4G Before coming to Morocco since I won the phone from a Dbrand's giveaway. I think it's brand new.
Shouldn't roaming be active when you activate it in menu ?
I turned on mobile data roaming and nothing happens. Check the picture for details.

I turned off my Data Roaming and the Mobile network state remained the same - connected. I'd think " Mobile network state " has anything to do with roaming being on or off unless one is roaming out of their Network onto another network.

I turn them on and off yet their status remain disconnected. I understand why.
I really don't understand how to get mobile data working on my phone.

Hopefully someone else will try and assist.
In the meantime
On the phone dialer enter *#0011# and *#2263#
Also, the mobile network state will be disconnected if you are connected to WiFi.
Should get the following screen.
Also make sure that the correct APN is entered and active / selected.
Then try and go to the connections menu and toggle lte/3g/2g... to 2 or 3 g and back to to 4g to see what happens.
Also make sure Mobile Data is turned ON.
Go-to settings then search for Mobile Data.

That's weird as when I checked Frequency check website with device sm-n950W and your service provider INWI , it lists it as fully compatible. The other Moroccan networks were not though.
This would be the second instant whereby Frequency check has got it wrong. First being Samsung device I used to own.

I checked the frequency myself and I came to the same conclusion.
I was only told today by an INWI agent that devices from Canada and USA always face the same issue.
I triend orange which didn't work too. Gladly, IAM worked as it is the largest and oldest network in Morocco.
From now on, I won't believe what websites say till I see for myself.

O2 is the only provider in the UK to offer WifiCalling. I'm on Vodafone and they are hardly cutting edge with their rollout of new technology. Searching on their forums there's no mention of it, so I don't think you'll be making the most of it any time soon.

The Vodafone forums mention missing WifiCalling button and the resolution is that it has to be pushed to your phone as an update by someone on the Vodafone tech support team.
More support calls to the worst support call provider.
