HTC One Mini No Mobile Data - HTC One Mini

Hey, my HTC One Mini keeps saying that I'm always 'Disconnected' whenever I turn on Mobile Data.
I have tried APNs of all sorts from my service provider (Virgin Mobile Australia) and none of them have worked.
(The APN Deselects itself, but I have set it and restarted on the same screen, which fixed the deselection error, but it didn't fix the above problem.)
P.S It is AT&T Unlocked.

HTC Cavalier is struck in roaming mode

HTC Cavalier is struck in roaming mode
--------------------------------------------------------------------------------
Hello,
I am new to this forum but would appreciate any assistance or ideas. I brought the HTC Cavalier two days ago. I have tweaked the phone to the point where the asian oriented programs have been removed and I am satified with the phone.
There was a network wizard that popped up everytime that the phone was rebooted and frequently during the operation of the phone. Because the phone was the HTC C730 asian model. The phone was set up primarily for that market.
I was able to get a cab file that stopped the network wizard called a netwiz.dat file. But, after using the cab file my phone was struck roaming. I have hard reset the phone twice and the network wizard returns. So in order to keep from roaming I must keep the network wizard. Luckily, roaming doesn't cost me anything but I would like to get this network wizard problem resolved.
Thanks in advance for your assistance.

Check to see which carrier the phone's linked to. If it's your home carrier, it's not really roaming. Be sure you've unlocked the phone as well and are uisng a SIM card form your home carrier.
The phone is linked to my home carrier Tmobile. I called them and they stated that my phone isn't showing as roaming. The phone came unlocked but I have CID unlocked the phone. But the roaming indicator is irritating. Is there any tweking I can do to remove the roaming indicator.
Thanks

[Q] Cannot data roam

On a recent trip to Germany I discovered that I cannot data roam.
My handset is a dev unlocked (upto date) HTC Pro 7 with a T-Mobile UK SIM.
On a arriving in Germany I rebooted my phone, selected the T_Mobile DE network and turned on data roaming.
Once connected I fired up internet explorer, it tried to redirect me to the t-mobile portal, where you are supposed to be presented with the option to purchase international access.
After a while it just timed out with a message saying that it could not connect and suggesting that i turn on data roaming.
I double checked the settings and rebooted, still no access. This time however it wasn't even trying to auto redirect. Selecting the url from history still resulted in the same error page.
Thinking that it might be a cache problem, I deleted the cache. Still nothing. Selecting other networks didn't help either.
I rang T_mobile, they checked for network issues but could not recommend anything other than wiping the handset. I was not willing to do this given that i could not be assured that I would have the necessary internet access to restore my data...
Has anyone else had problems roaming with T_mobile on WP7.5?
Tnx

Mobile Network Not Available

Hi folks,
This is my first post on here. I'm having a problem with my phone which I think is quite unique and I hope someone on here can help me fix it before I buy a new device.
I have a galaxy nexus (maguro) running cyaogenmod.
Previously I was running CM11 (cm-11-20141115-SNAPSHOT-M12-maguro) from the CM website and updated it to CM12.1 cm-12.1-20160719-SNAPSHOT-YOG7DAO8DL-maguro) a few weeks ago.
When I rebooted my phone it was running very slow (and getting very warm) so I did a factory reset and re-installed CM12.1.
It started working ok but I noticed that my phone was displaying 'emergency calls only' even though the network reception in the status bar was full, displaying 'H' (3g) and allowing me to connect to the internet using 3G.
Whenever I make a call it states 'Mobile network not available' and I cannot send text messages.
I tried phoning O2 and they gave me a new sim but the problem was still happening. I then tried putting my girlfriend's EE sim into the phone and I could make calls/send messages. I also went to France on holiday and could use my phone to phone/text using my O2 sim abroad. Whenever I put my O2 sim into another phone I can make calls and text.
So basically it is only when my O2 sim is specifically in the Galaxy Nexus that I cannot make calls/send texts but can still use 3g.
Oh yeah when I go to Settings>Mobile Network Settings>Network Operators the following available networks are shown:
O2-UK
T-Mobile UK
3 UK
vodafone UK
Orange
When I select O2-UK is states 'cannot connect at this time. Please try again later'
I've tried re-installing the older version of CM11 and today I tried wiping the entire phone (internal sd card etc) and it is still happening. Can anyone help? Is there something else I can wipe, or setting I can change?
Thanks in advance

Settings still showing old network

I recently changed from O2 to Three and the new sim is working fine with no issues. Annoyingly in settings, connections it still shows O2 as network provider even though I’m connected to the Three network. I’ve tried re-connecting to the network both manually and automatically and still it shows O2 as network provider. I also tried resetting network settings and no difference. This has no bearing on use and I'm definitely connected to Three, I just find it irritating seeing O2 incorrectly showing. Is this a bug or is there any way to fix this?

HTC U11, Dual Sim, unlocked, Mobile data is not working in T-Mobile, ATT networks.

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.
