I recently purchased an unlocked HTC HD7 from Ebay.Its At&T phone. My area is covered by 3G services but only "E" is shown beside the network bars on the phone. I have tried ##3282## and switched on 3G only. When i do this, it automatically switches to Emergency calls i.e. It does not support 3G at all. i cannot make any calls after i switch to 3G only. I have tried manually updated the OS from 7.5 to 7.8 from instructions provided by xda developers but it still does not seem to work. Under Settings, cellular, there is no option for 3G. Please Help

Hi everyone,
I bought a Samsung Galaxy S GT-I9000 (16gb) in Singapore and was using it fine on Singtel's network (signed a contract with them). Now I have moved back to Canada and brought my phone with me assuming that all would be ok to use it with the network here. However I'm having big problems with this one network I just signed up with (Virgin Mobile).
85% of the time I cannot connect to it: voice calls and SMSing won't work nor will the data work on it, the only thing it says is "Emergency calls only". Then at other times everything will seem to connect and work fine - I can make calls and use data.
Virgin Mobile will not support me much because they're thinking it's the phone's problem, if I use the phone they gave me (a lower-end model) it works fine.
Here are some details of my phone:
Firmware version
2 2
Baseband version
I9000DXJPA
Kernel version
2 6 32 9
root (at) SE-S604 #1
Build number
FROYO DXJPA
If I check out the status, it usually says this:
Network
Unknown (switches to VIRGIN when it does work)
Mobile network type
UMTS (switches between that and HSDPA and GPRS)
Service state
Out of service
Mobile network state
Disconnected (switches to connected when working, and even when it's not working sometimes)
I have Network mode set to auto mode (GSM/WCDMA). I've tried to switch it to GSM only but that didn't seem to change anything.
I'm wondering if there's some kind of configuration settings I still need to do with the phone? I'm also wondering if it is the network I'm with right now? Virgin Mobile isn't one of the bigger telcom companies here and I'm thinking that if I switch to one of the bigger telcoms, will it work better?
Something else to add - before I signed up with Virgin I was using my phone with a pre-paid service (called Chatr) for voice only and it was working fine.
I'm sure this phone can support the GSM frequencies here.. can't it?
I also still have the Singtel customizations on the phone. Will it help if I remove it?
Any help would be greatly appreciated!
Thanks a lot!

sorry, wrong category..
I am new to the forums, so please go easy on me.
A quick back story....where I live, I have to use a Verizon Network Extender to make and receive calls & texts from home. VZW's Extender only works with 3G. Since the upgrade to 4.1.1, the mobile network menu only has choices of Global, LTE/CDMA and GSM.
Until yesterday, I have been using an app called Phone Info to manually set my mobile network to CDMA Auto (PRL) when I got home and it worked perfectly. Since the update, the Phone Info app no longer works and I cannot find an app that will allow me the same access to set my mobile network. I receive just enough of a 4G signal where I live that my phone will not auto switch to 3G. So now I have an expensive paperweight at home.
Can anyone point me to an app or tweak that could help me with this problem?
Thanks in advance.
Hello,
I know there is a thread for this in Galaxy Note section, but i feel i need to share this for OPO community.
I'm using OPO v33 rom. I live in Mumbai and have a 3G vodafone postpaid corporate connection.
Recently i have been to my native mysore on few occasions, and everytime i have seen the 3G data getting disabled even when the data connection settings are enable on roaming.
I never faced this issue on my nokia lumia 920 which perfectly latched onto roaming and 3G data was available.
On roaming, with OPO, the data gets disabled and i dont get a specific "E" or "H" sign with + noticafion.
I only have the signal bars with small R icon on top of the bar.
Please let me know if there is a workaround for this.
I have also seen this issue on v25 rom aswell.
Note: i have tried setting connectivity to automatic in mobile networks.. and also tried to select the specific Vodafone network. both didnt solve this issue.
Another interesting thing while on roaming: my nokia 920 recognised 2 networks for vodafone.. one with 2G, 3G and another with only 2G. and i could select the first one .. and 3G was getting enabled without any issues.
i think that E and H as well as H+ is only something you can geti n your own country. When roaming, it's always the default for that service prodiver in the country that you will get.
Hi all,
Currently using Xperia Z2 with KitKat. My carrier is DST (Brunei). My carrier uses three separate operators - LTE DST, 3G DST, 2G DST, all viewable in the network operators search page.
Quite often my phone decides to drop down to 2G DST operator as the preferred, without desiring to change back up, even with switching on flight mode. If I manually search, I can see all 3 available, and if selecting either 3G or LTE, they operate smoothly for a while - 20mins or until I lock my screen.
I have noticed this with previous phones on this carrier too.
Is there anything that can be done to either lock out the 2G one, or make the phone understand that is only a last resort?
Thanks
Hi.
I have HTC U11, Dual Sim, the International version that I bought from China.
After that, I have changed the CID for it on the Taiwan version.
Currently, it is:
HTC_U-3u
Android 9
Software number 3.22.709.2
Rooted, not custom rom.
I have been used it with several MVNOs (Mint, Hello mobile) that are working on T-Mobile network for the last 1.5 years. Currently, I use Hello mobile.
All worked fine (4g, voice, text, data) until last week.
From the last week, Mobile data is not working anymore. It always shows as "Disabled" when I try to enable it, and no icon in the status bar. Meanwhile, voice and text are working fine.
I didn't do any system updates or new soft installation on my phone.
I tried to reset network data, reboot, checked with support (no issues with my number), checked APN with t-mobile recommended, changed mode on 3g, 2g, and without success, mobile data is not working.
I tried to put my sim card in another phone that I bought here in the US and the mobile data is working fine there, I see the LTE icon, and so on.
Also, I checked my phone with a sim card from ATT, and the same issue, voice, and text are ok and no mobile data.
The Signal Spy app shows me that the phone connected to Band 4 (1700). I checked T-Mobile and ATT websites and see that this Band in the list of supported 4g bands.
Also, I checked the compatibility by IMEI on websites and it showed me that only WiFI-Calling and VolTa will not work on my phone, but common 4g data is supported.
So seems all should be work fine but it is not. I found some posts on Reddit that T-Mobile wanted to change some Bands from 4g to 5g, but I don't know if it is the root of my issue.
Does anyone have this issue with this phone in the US on T-Mobile?
I don't know what it was but today Mobile Data started to work, the whole past week I had no mobile data connection.
