Is there any way to Network (Sim) unlock?

Couldnt find any threads on this so posting here.

Major problem with Network System Provider

I froze Network System Provider in "Titanium Backup" because I literally would have the message "NetworkSystemProvider has Stopped" popup 2 seconds after I would press OKAY on the message. Please if anyone knows how to fix this issue I would greatly appreciate being walked through the process."
Also, in Google Play Store I can only download 1 app at a time, then once that app has downloaded it takes a while to actually install. Other apps that I download while another app is downloading or installing will give the message "DOWNLOAD PENDING". Is this problem related to the NETWORK SYSTEM PROVIDER or completely different. Can someone help me figure out how to fix this issue also.
Thank You,

Network unlocking j7 t-mobile via root

Hey Guys! Recently I purchased a samsung galaxy j7 model number j700t (t-mobile variant) .The device is okay but the device unlock app isnt working . I want to be able to use it with other networks. I saw in a youtube video(am a new user so am not allowed to post any external links) guys who call themselves the vietnam gsm team demonstrate how it can be unlocked using an external adb shell app and a phone app called the phone tool which uses root access.They have not posted the links to the apps nor the procedure. Is there anyone out there who knows how I can unlock my rooted device using a playstore app called the phone tool and a somewhat unknown adb shell app?? Thanks alot

T Mobile M8 could not be activated on Network

Greetings. I have bought a T-mobile M8. I unlocked it and also twrp custom recovery done. Bootloader 3.19. S-ON. My problem is I am trying to use it in Europe but it is not working.. only offline mode. I am a happy h/k Sprint M8 user since 2014 and I have bought this for present, but I can't make it working. Do these unlock codes ( I have found for 9$) would do the trick? If sunshine works, what should I do after that to make it working?

Thank you very much!

My p8 lite won't connect to WIFI , it says refused access to network

Issues with network & GPS

I just bought an unlocked version from HTC. Out of the box I noticed that the network stops working after restarting or randomly, prompting another restart to fix it.

Also, the GPS seems to have problems locating properly. Navigation kept rerouting over and over on any given day.

Factory reset seems to have helped a little but I had an issue with the network this morning, which was fixed after restarting. GPS has issues in Pokemon GO now, which could be app specific but no navigation issues now.

Is this common for a brand new phone? Kinda disappointed.

Galaxy S6 - NO NETWORK, No IMEI no baseband NO EFS Backup

On my Samsung Galaxy S6 which was Vodafone before, on 6.0.1 I flashed twrp everything was working perfect fine apart from this time I forgot to backup my efs so now i have an unknown baseband and also an unknown IMEI, on the notification bar there is a prohibited symbol, like a constant silent mode, I was wondering is there any way either somebody can send me there backup, or any way I can get my phone back in to working order?

Cellular network not available - But mobile data is working

When I try to call or text someone the message or the call fails to work. The 4g connection seems to be working fine though. Running a Moto X Pure on Verizon. I have rooted the phone but have traveled back to a stock rom and still no success. Is there any solution to this problem?

I have tried to factory reset the phone but that does not work. :(

problem in network

Mobile network signal

I'm not sure it's a problem, but is anyone also facing a similar situation. I'm on Orion OS(also happens on krexus-caf) if I go to battery settings and click on the graph, my Mobile Network signal is almost fully orange. However my signal bars in status bar are almost always full, and an app(Mobile Signal) shows a good dBm, around -70. So I checked by typing *#*#4636#*#* in phone dialer then -> phone info and it shows around -70dBm but after a few seconds it drops to -113dBm(which is lowest possible), then back up to -70 then down to -113 again. Is anyone facing a similar issue?

Thankks

Network Signal Drop after installing Facebook hello Caller id

Hi, i don't know if it is the right thread but i'm facing an annoying issue on my LG D855 (Fulmics 5.3 custom ROM), after i install Facebook Hello Dialer App (Caller ID & Block) i have a constant network signal drops, like every 2 secondes, and every time i try to place a call with or without the app.

The app itself works fine to identify and fetch peoples data (over wifi of course). I can't figure out the problem, i tried switching between network modes (2g/3g/4g/auto), disabled/enabled sync optimisation, but nothing resolved.

The app was sideloaded since it is unvailable here in Algeria, maybe be because of network bands in my country (slightly different from US ones, despite i don't see relevance here), but i installed it on a bunch of other smartphones and all went ok (1st gen Samsung Galaxy A3, LG L Bello, and even a chiness clone of the Hisense u970) (all on stock roms).

If someone can help me it would be nice.
Thank you.

Any update on the 'Network Error" during installation?

Searched around everywhere and the issue seems to be relatively widespread. During the Gear VR installation process, the install button becomes greyed out, stating "Network error occurred. Try again later."

Im using a Galaxy S7 Edge (G935F) stock ROM rooted +xposed.

I've tried editing the CSC file at /system/csc/sales_code.dat but this hasn't done anything!

I'd prefer not to wipe my phone and go through the hassle but if it that works (I've heard it doesn't) then I'll give it a shot.

Any help would be greatly appreciated, thanks!

Verizon Galaxy S5 video calling and some other network stuff on T-Mobile network

I have a Verizon G900V S5 that I am currently using with a T-Mobile sim card on the T-Mobile network, I can get voice calls text/data etc, but I cant find a way to activate the video calling because its linked to Verizon its currently on android 5.0 and I cant manually update it from the phone either because it says im not on the network, is there any tweaks or roms to fix these? Also whats the best network mode I should be on to get the fastest data right now im just leaving it on "Global" and using T-Mobiles APN and it seems alright

cellular network not available, but data works?!

Hi guys, now it's time for me to ask a question. In all my years with android I haven't felt so powerless :p

I'm experiencing a strange behavior with my N5X: I regularly get an error "cellular network not available" when trying to call someone. During that time I'm not able to make calls, receive calls and receive or send sms messages. The strange thing: LTE, H+, H, E or G connections are working during that time.
A reboot fixes the issue for some time, but after some time (minutes or hours) the issue is back. As I said, my whatsapp service and internet connection is available via LTE or similar (depends on the quality of connection), but all GSM services won't work.

I haven't changed the SIM card.
I flashed several different ROMs an kernels.

Thanks

Not connecting to 3g network but 2g works fine in my mi3w.

MANY HAVE THIS PROBLEM AS I CAME ACROSS MANY COMPLAINTS SIMILAR TO MINE DURING MY BROWSING. SOMEONE PLEASE ANSWER.
My xiaomi mi3w suddenly quit connecting to 3g network even when it is available. I tried switching to wcdma mode from settings as well as by forced method. The sim card works fine with other phones. I tried factory reset, booting back to stock version, updating, etc. During the time glitch started I was using global developer ROM miui7 . I didn't do anything unusual. I can see my imei no: from settings.. what to do? It's serious..:confused:
