Recently got a Phone as the titles says, Unlocked Docomo Samsung S4 SC-04E 14.1 lineage OS.
Installed my AT&T SIM from my troublesome OEM Samsung S4 i337 into the Lineage S4 and everything worked fine for about 10 days after setting it up and using it.
Then it suddenly stopped connecting to AT&T Mobile Data, so no email, no internet, but can still make/receive phone calls, and send/receive Text messages.
If connected to WiFi, everything is good with all functions.
When not connected to WiFi, the Mobile data Symbol is lit up and, it says AT&T, and every setting I look at, including dialing *#*#4636#*#* it shows AT&T as the network, but that's the one place it shows it is Not connected to data and the ping test fails.
Spent days and hours talking with AT&T Tech support and they couldn't get it to work, so they sent me a New SIM card, which did not help either.
I then went to an AT&T store and they could not fix it, so I tried numerous times using those "how to fix no Mobile data connection" with no results.
My thought is why was it working fine with Mobile data for so long, and then stop working.
Would this have something to do with the Lineage OS.
My other question/thought/last resort at this time, is how to clean reset the phone without losing the Original Lineage 14.1 settings, and start over by putting my SIM card in to see if it Connects to Mobile data on it's own like it did originally.
Any help is appreciated.
Regards, Frank

it started 2 days ago. my mobile data is not working, although my signal is OK (i can make calls or send sms, but I cannot open any website, whatsapp,... unless I am using WiFi).
I have reseted the phone, factory reset, hard reset. Switch it off and on several times. Remove and put again the sim card.
My Company is 3 UK, and it seems to work perfectly ok. Asking some friends with this company, it works for them.
Nothing happened to the phone these last days which made it to stop working. I don't really know when it started because I mostly use WiFi all time, but I realised definitive yesterday it was not working.
on status it says network 3, but then says mobile network type unknown, voice in service / data out of service, mobile network state unknown, my phone number unknown.
although as said, I can perfectly call and so.
the phone is not rooted, I am using everything as it came by default, updated to 4.4.4 it was a network free phone bought in Tesco
Hello everybody,
I have a Verizon HTC One M8 that I'm using with MetroPCS. I'm trying to figure out why I'm having connection issues. The first ROM I tried was Skydragon. It worked very well and I could get voice, MMS, and data to work. The issue was the phone randomly loosing it's connection. Sometimes it would be after a few minutes, sometimes hours, or close to a day. Rebooting the shell would usually be enough to get it to start working, but not always. I tried loading it for T-Mobile, International, and Verizon. The only difference between the three would be the unknown SIM error in the Verizon version. Yesterday I loaded the ViperONE ROM. It seems to reliably keep my voice and MMS functioning, but data has been difficult. I can set APN settings and it will have LTE service for a bit, and then it seems to forget everything and ask me to select my provider again. I get an Install SIM message at random times, and at other times I get a new SIM installed message and it ass me to choose a provider again. I'm going to try Android Revolution next, but I wonder if there is another issue, or if anyone knows what the best ROM is to get this thing working on MetroPCS.
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
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.
I recently bought a Note 20 ultra off eBay about 3 weeks ago. I have Page Plus and have had them for about 10 years. I called Page Plus and registered the phone or SIM and IMEI and I had no network data but Wi-Fi, SMS and phone (over Wi-Fi I guess) is working but if I turn the Wi-Fi off there is no internet. I contacted Page Plus several times but by the 10th phone call I was going nuts so I assumed it was a bad card & ordered a new SIM, however it is the same situation. I'll submit any info needed, I really need to get this straightened out quickly, my mom is in the hospital and even though most of my calls are coming through I need to make sure everything on the phone is working In case of an emergency. When I'm driving down the road I cannot get any phone calls or text messages.
Device settings...
No one?
Seems like Samsung screwed something up
I had a S20 PLUS (G986U / u1) which was working fine on android 12. Factory Reseted it, gave it to someone who updated phone via ota and now it has no data
But my case is different, I I can't even type out apn for mobile data, when I press the Access Point Name nothing happens, doesn't let me in the apn menu to add/change it
Hey! I'm having the same issue with my Note 20 Ultra, US edition! I can make calls, but mobile data is not active and I also can't change the APN! The menu is not opening at all and also, it's not greyed out!
P.s. - from India, with Airtel SIM.
Mine is Solved! I think it has something to do with the ICCID, SIM or ESIM situation. See attached photo. I called Page Plus for the fifth time and told them my network showed as disconnected. She reset my account & I went through a certain order of steps, I shut my phone off, removed my SIM card (gave her the number again, for the 5th time), restarted, reinserted my SIM, turned data on, roaming off & Wi-Fi off, restarted my phone, toggled between wifi off & on & Boom! The LTE sign popped on, now I'm able to use both, the LTE sign doesn't show when I'm signed into a Wi-Fi network but the mobile data is now definitely working. Hope that helps.
Glad it worked out for you!
My situation is a bit difficult as it's not an Indiam handset (Samsung released the Exynos mode here) and my current service provider (Airtel) has no idea about my situation.
Will keep looking, if someone can crack this!
