Randomly, earlier today my Galaxy S7 went from having signal fine to being unable to successfully connect to a network.
The problem is not the SIM, as I tried my SIM in another phone (fine) and a working SIM in mine (no luck). I even tried a different network but no luck.
The problem survives a reboot, and I tried resetting the network settings. I also tried clearing the cache partition. I haven't yet tried a full factory restore.
I'm on the latest S7 firmware - I'm a beta user for the Android 7 firmware.
Anyone had this issue and know a fix? It could be hardware but I'd find that a bit odd... I suspect something software is going on, as it detects the SIM fine, and shows a signal that fluctuates, it just seems unable to connect properly...
Thanks!
Resolved... turns out the phone I got 2 months ago (from CEX) had since been blacklisted - and it kicked in yesterday. I took it back to them, they're raging but I got a replacement!

I've been having this problem with my Samsung focus for like 4 days now. It refuses to connect to my network provider. I've tried everything; hard reset, reflashing stock At&t rom, different sim cards. My network indicator keeps saying there is no signal, but sometimes I get edge connection randomly but it leaves almost immediately. I've looked all over for a way to fix this problem but no one has ever been able to fix this problem. What can I do?
So, I have a problem with XT926. Almost every 5 minutes I get message "Restricted access changed", and phone loses GSM signal. Then it reconnects to the network. And there is no HSDPA mode anymore.
For 1.5 months everything was fine, but after I went to a trip and used phone in roaming mode, this problem appeared. I am using safestrap and two roms, stock and FlyingJelly, the problem occurs on both. Just flashed new modem(using RazrHD-Toolkit-4.0) the problem still here.
Google says, it is rather common problem, but no reasonable solution. I used sim in another MAXX HD running CM10 and it works fine.
Please, help.
Hi!
My girlfriend (who is forever having problems with phones) just bought a Nexus 5 after her Galaxy S2 spontaneously gave up on life, but despite showing a full signal it seems to be unable to connect to a network (it's supposed to be on the UK's Orange network). When it first started up she said it had a screen saying something like 'activate data services', but that after 10 minutes or sitting on that screen and apparently stuck, she skipped it. The phone is showing a full strength signal, but no calls/texts or data works.
We've been unable to get back to that screen, even after doing a factory reset with/without the SIM inserted.
Anyway, I figured it was an APN issue, so I've tried setting it up for her, but whenever I create a new APN and try to save it, it just disappears and loses all of my settings. I've had a look around XDA and it seems a few others have been having the same issue, but nobody I've seen has posted a fix. Does anyone have any suggestions?

Tried it with my SIM in her phone and it works fine, so I guess it's a SIM issue. Sorry about that. She can call the phone company tomorrow.
As stated I'm using the LG G5 H830 T-Mobile variant. I am getting 4G LTE data connection and everything runs well (Not in any WiFi range) Yet for SMS and calling as well as mobile hotspot I get "No USIM card' error. This happened after wiping the system and formatting data. Rebooted recovery (as per instructions on forum) then installed the stock firmware & Patch with systemless root and xposed. After this I did factor reset when just pulling the sim didn't help. Still nothing. I reflashed just the stock firmware with TWRP and SuperSU and issue is still happening. I've disabled rebooted and enabled the phone radio. SIM is in good condition and tray as well everything is SECURE and should be good to go.
I'm assuming a new SIM might be a solution. But I'm not counting on it and with Labor Day tomorrow for me I wouldn't be able to pick one up for 2 days. So here I am...hoping someone might have a fix. I know I don't have many posts on here. But I am an experienced user....just not with the more basic of problems I guess
Thanks!!
Has anyone else experienced this yet? I'm just curious...I had it fixed for a couple days. I've formatted data and done complete system wipe. Tried it resetting phone with the COMPLETE zip and TOT using LGUP. I'm receiving texts. Not calls. Not able to send either. I've activated new sim, didn't help. LG support just told me to look into warranty. T-Mobile needless to say just wanted. Sim card does show stock tmobile short code contacts but phone number shows as unknown. Hotspot won't work. I've tried setting the phone number to the sim. Nothing.
Anyways. I don't think I messed with anything, even so I've done everything to start the phone from scratch. Going to replace it, just more or less curious at this point and maybe others have had the same issue.
I believe I had the same issue as you and it was driving me crazy. I was constantly wiping data, system, etc but my phone kept giving the message "roaming indicator off" where it should show the name of the carrier. This resulted in me having LTE data and that's it- no 3g, no phone calls, etc. I couldn't even access the mobile network menu.
What ended up causing the issue was the network mode setting under wireless networks. Keep in mind at this point I'm running a patched rom which now gives more options in the network mode menu than the phone came factory with. I have an area at work where I have to switch to 3g, GSM/wcdma preferred network setting, because although I have full LTE signal, my connection goes dead. When switching back from 3g I chose the setting lte/CDMA thinking this would force my phone to stay in lte mode due to another area on an upper floor where the phone will constantly drop lte.
Anyways this resulted in my phone saying roaming indicator unavailable, the inability to make or receive phone calls, and either the mobile networks or network mode menus being grayed out. When stuck in this mode there is no way to put the phone back into the standard "GSM/wcdma/lte" mode. Even a complete reflash won't fix it. I even used lgup, which worked for maybe a day until it force closed the phone app and went back to roaming indicator unavail. I wiped every partition and even reflashed radio firmware. Nothing worked.
What ended up fixing it was using an app called v10 hidden settings which allowed me to access the network mode menu directly and re-choose the lte/wcdma/GSM setting. Incidentally on first access to this menu through the app there are only two network settings available. Once you choose a GSM setting, the rest appear.
I'm not sure if this was your issue but I hoped this helped because this took me about a week to workout.
Hi everyone.
I hope someone can help me please. I have an old Moto G3 phone I want to give to someone so I’ve uninstalled everything personal off the phone and then done a factory reset.
Now for some reason I cannot get it back on to my home wifi to finish setting up the phone. Initially, I selected my network and then input the password but all it returned was ‘Authentication Problem’. It then stopped even being able to find my SSID on the available networks but eventually it showed up again but still doesn’t connect. I originally bought the phone second hand from ebay a few years ago and it had been factory reset by the seller. It isn’t rooted or locked to a network. I’ve never had an issue connecting it to my network before tonight.
However, the phone has been turned off in a drawer for several months. About 7 weeks ago I had to install a new Virgin Media Hub-3 modem as the previous modem was dying of old age so tonight was my first time attempting to connect this phone to the new modem. I normally have 11 different devices connected to my wifi at any one time and all of them work perfectly.
I’ve tried absolutely everything I can think of. My other devices all see and are connected to the network completely fine. I’m literally sitting within 2 feet of the modem and it’s showing a very strong signal.
I have tried the WPS button, WPS Pin, rebooting the phone, rebooting the modem, resetting the network settings, rerunning the factory reset, making sure the modem is set to broadcast the network name, inputting the SSID and password manually. I even tried disabling the modem firewall in case that was blocking the phone and I must have manually typed in the wifi password over a dozen times which I keep noted down and I know is correct. Basically I’ve run out of ideas. As the phone isn’t locked I also tried my the sim from my current phone to test it. Although it can make calls no problem, I still can’t get on to my home wifi.
I’ve tried turning off the wifi and shutting down a couple of my other devices and then turning them back on and they reconnected to the wifi straight away without a problem. I can’t believe the problem is with the modem as it’s only 7 weeks old and everything else is working perfectly on it.
I’ve also tried googling the problem but still no luck so far.
The phone is on Android 6.0.1, it’s a Motorola Moto G3 with a 16GB microSD card but has no sim card installed.
