Hello,
in Uk a brought a Galaxy-S (T-mobile) and unlocked it. Now I'm back in Italy and I put my old SIM card. The Phone works, except for 3g, edge or any mobile connectivity. I think there is two options:
- The phone is still locked.
- My sim is very old (from 1999), may be no more compatible with 3g.
How do I find out which is the case and how I solve that?
Thanks guys (girls too).
No network
Hi m8
Could you please check your imei number, I did exactly the same.
I bought my sgs on firmware 2.1 & unlocked it via free unlock tool, I then messed with some new firmwares. Recently tried to sell my phone as unlocked but when buyer put their sim in, It shows a signal but no data network connection.
After messing around with different sims i did a check & noticed my firmware is some stupid 04999????
Regards
Mark
What does that mean?? Is it related to IMEI somehow?? What should I check about it? How do I fix that? I've 2.2 by the way
Hello modders,
I am considering buying the Xperia Z because I really like the device and software.
However after my first hands-on experience, I have discovered that the c6603 model, sold by our carrier (T-Mobile CZ), seems to have LTE disabled. Although the service menu does show all the supported LTE bands, when I go to Settings-Mobile networks and try to change the enabled networks, only the following options are available:
- WCDMA only
- GSM only
- WCDMA/GSM mode
The question remains, how this is controlled and what can be done to enable the search and support for LTE networks.
Is this stored somewhere in some carrier settings file? Is it carrier specific, so that with some operators, this is enabled automatically, for others it's disabled? Can we change it somehow?
I am not feeling quite well about these options being disabled per-carrier.
Thanks.
I think flashing unbranded firmware will work for you.

I found in the UK, the option was missing on my UK Phones 4U firmware (350).
I thought it was some mods initially, but after applying the Greece FTF unbranded update (434), i got it back, even whilst running the same mods.
I flashed the UK 434 FTF update, and it's missing again, with the same mods.
These are only stock mods, status bar menu icons, reboot mod.
I will re flash the Greece Unbranded FTF and confirm if it's still missing, if it is not missing, for some reason, the UK unbranded FTF's (350 and 434) have it missing.
I flashed the .434 Nordic ftf and the LTE option is there. It wasn't on the original 3 rom.
I can't notice any difference at all that its a Nordic ftf and not a uk one, so I'll stick with this.
if LTE option is missing, it's only the option concealed but LTE is still there.
the culprit may be /vendor/overlay/com.android.phone-res.apk. try delete it after rooting.
otherwise, just ignore it and dial *#*#4636#*#* to enter what mode and you can see LTE options there.

This is controlled by your vendor's customisation of the ROM, I am guessing if they have removed LTE, then they do not support it. Therefore not sure why you would want to add it back, because you will not be able to use it. Because once your vendor supports LTE, I am certain they will send you out an update.
My phone has LTE, my provider has LTE. But I had no LTE on my phone, until I changed the plan I was on. And I couldn't force that on, because the vendor blocked that.
In addition as stated here any generic ROM should give you the phone/ROM in all it's glory, provided your vendor has LTE
Did you choose the correct setting in mobile network

I bought a Phones4U unbranded XZ a few days ago, with a T-Mob contract, and it DOES have the option, it had on when I was on 350 and it still has it now on 434. Perhaps it's related to the APN settings that the carrier sends you OTA? Obviously T-Mob is part of EE which has 4G so that could have done something.
I don't understand why your XZ doesn't have the settings though.
Are you sure you have the Z supporting LTE? There is a LTE and non LTE version on sale.

This was my next question, is it possible that the UK firmware reads the SIM card first and then 'knows' wether your current network is able to run LTE / 4G, if it's not, it only allows you to select the most appropriate setting, in my case GSM / WCDMA
Im on o2, not 4G, but the option was still selectable on my old Xperia V, and the Greece Unbranded Xperia Z FTF.
Have you tried a non 4G SIM / network in your phone to see if you get the option or not? Or could you...just to rule this out? If it is most likely APN related, then am not fussed, as soon as O2 has 4G, i should be able to utilize it
Cheers

Again only if your provider has locked this part out of the sim card, pretty crap if they did because this can be easily be controlled from within the network. Because when you scan it should show all networks around even ones you can't connect to, if not they have locked certain bands on the sim
HI, GUYS,
so I just got this unlocked HTC ONE from HTC shop
and I am currently using T-mobile, but I have issues with 3g
i used to have HTC desire z and 3g works fine,
and I went to shop, change my sim card to micro sim card so that i can use it in HTC ONE
BUT, everything works perfect excepted 3g
mobile network only can find T-mobile 2g network and at&t 2g/3g/4g network when i search the network operators
and i am not going to do roaming.
I tried to change VPN but it doesn't work
I also tried tweakker, but for some reason, it kept saying my wifi didn't connect to internet but it did connect to internet..
so could somebody help me
i didn't root my phone yet, and the rom is official rom
Software number 1.29.1540.16
thanks
You're not going to like this answer, but the unlocked HTC one lacks the 1700 band needed for T-Mobile 3G. The good news is T-Mobile is in the process of reforming their network so your phone should get 3G by quarter 3 2013. Until then you could try an AT&T mvno or return it and buy one from T-Mobile that has the required bands.

Hi I bought an unlocked, Verizon branded Moto X Developer Edition which I intended to use on Koodo in Canada, which runs on the Telus network. When I put my sim card in it has trouble connecting to the network. It connects for a couple of minutes, and then loses the signal for a couple minutes, then picks it up again and so on. It's like it is connecting to cell towers other than Koodo/Telus and cant use them.
I have tested the sim card in another phone and it is fine. I have spent a significant amount of time with Koodo customer support and it has become obvious the problem is with the phone. It doesn't matter if I have it set to global or LTE/GSM and connect to Koodo that way, both have the same result.
Has anybody run into a similar problem? I absolutely love the phone and would hate to find out that I can't use it. I live in London, Ontario and shouldn't have any issues with coverage.
Thanks
I have The exact same problem with a moto X from ATT trying it on Koodo. Maybe flashing the Telus rom or dev rom on it could work. Mine is in 4.4.4 with ATT so I can't unlock the boot loader to do that but maybe you can...

Have you tried manually entering the APN settings?
The Verizon XT1060 (Dev Edition, or non-Dev Edition) is SIM unlocked out of the box. So forcing to GSM mode should work, as long as the APN settings are right.
As a side note, to use a T-Mobile USA Sim, I've had to manually enter the APN settings on my Dev Ed VZW X.
I bought a D6603 unlocked online few months ago and was able to get on Tmobile LTE without issue till recently, where the LTE connection keeps on dropping and I have to download the internet setting everytime in order for me to get onto the network.
I have checked the APN setting and also obtained a new SIM card from Tmobile but the issue remains. Based on the Tmobile store associate Tmobile is currently making updates to their network and international devices might not be able to get on their network. Does anyone know if there's anyway around it in order to keep my device on their LTE network? Or force the phone to use only a certain band on the phone?

The same thing happens to me. I have switched to HSPA. It all started after 5.1.1 update
