Hi, using an HTC Mozart at the moment, and it's detecting my SIM and mobile network (MTN, South Africa), but constantly switches between full signal and no service, and when at full signal, the phone refuses to make or receive calls and messages. Does anyone know what might be causing this? Is it a phone or carrier issue?
I recently did a factory reset, and the software is fully updated (according to Zune).
Thanks in advance

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 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
Hello All,
I have this phone for about a week, i have one major issue with Mate 9.
Whenever I send or receive MMS messages, my cellular data connections would stop entirely. My remedy to this issue is switch on and off the flight mode, then everything would resume to normal (but i can't do this all the time). I have tried to reset APN and got a new SIM from my wireless carrier, but no success. Has anyone experienced same issue as mine? How do i resolve this issue? please help!!
same here, phone from Dubai, I am on T-MO
Hello,
I'm having trouble using my phone in roaming. My home mobile provider is Vip net., in Croatia. I'm currently in England, and my phone is currently connected to Vodafone network, which a partner of Vip.
I'm unable to get mobile data connection unless I'm connected to Vodafone 4G network. When I do a manual scan of networks, I can see (most of the time) three instances of each network (4G/WCDMA/GSM). Whenever my phone decides to switch from 4G to WCDMA or GSM, I lose the mobile connection.
APN is of course set correctly since otherwise I wouldn't be able to connect to the network on 4G (I've even had my provider send me the APN configuration message to make sure that's correct - I also tried various modifications to settings of the same).
I've talked with my providers technical support and they haven't been able to provide me with a solution, so I'm wondering if anyone here might have a clue about what is happening?
I've tried doing some basic diagnostic with adb, but haven't been able to gather much from modem logs, which I've attached here, and I would be grateful if anyone would take a look.
Here is the log, please note that it starts with me turning on mobile data and ends with me turning it off:

The phone in question is LG G5, Android 7.0 Nougat, Stock rom. (I had the same issue on 6.0)
Thanks guys!
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.
