A confusing problem with my phone's cellular network service. - General Questions and Answers

Hey guys. I have an unusual problem with my phone.
I was using my phone one night while in bed, playing a game that requires online connection when suddenly, my phone slipped from my hands. I managed to save it from falling to the floor, but it hit the wooden frame of the bed in the process. I checked the phone out and noticed no problem with it. The screen was fine, nothing broken on the exterior. So I tried to go back to my game, but it complained that there was no internet connection. That was when I noticed the signal had disappeared and the phone displayed "No service". I tried turning airplane mode on and off........nothing, restarted the phone.........no change. I turned off the phone and went to sleep.
In the late hours of the morning, I switched it on, and was greeted with the "emergency calls only" warning. I tried removing and re-inserting the sim card, restarting the phone and when I tried everything I could think of, I did a factory reset on the phone. Still, nothing changed. So, to rule out the possibility that the service was at fault, I removed the sim and inserted it into my brother's phone. It worked as it should! I inserted my brother's sim into my phone, same thing. At times, I get "No service", at times, "Emergency calls only", even some times, I get "No sim card", when there's actually a working sim card in the phone. These led me to believe the phone isn't detecting sim cards, but sometimes, the phone recognizes my sim card and the signal shows up, but I'm unable to use mobile data connection, make or receive calls or texts, or even dial a code to check my airtime balance.
So I decided it was definitely the hardware that had developed a fault. But then, one day, I went to visit a friend quite far away from where I lived, and I took my phone with me. To my surprise, my phone worked flawlessly there. I was able to use data connection and was getting good speeds. I was able to call and text. I removed the sim and put in another sim and it was the same.........worked flawlessly. Now, I don't know what to think anymore because as soon as I got back home, I was again getting the No service/Emergency calls only warnings, and the same sims work in my brother's phone - my brother lives with me.
** I know (or think) it's not a software problem because it would have been resolved after I hard reset it. Plus, it all started when it hit the bed.
** I know it's not the service in my area because the sim works in my brother's phone and my brother stays with me.
** I can't decide if it's an hardware problem because sometimes it works, sometimes it doesn't.
Some facts about the phone (if it helps)
** The phone is rooted
** It uses a sim tray. The type that allows two micro-sims or one micro-sim and one sd-card.
** The phone gets hot when I use it extensively.
I'd appreciate any help. Thanks guys.

[Q] Activation Issue

Hey there,
I recently bought a Charge from swappa.com. I have 6 months left on my contract from when I bought my Incredible, but that thing barely works anymore. The Charge came without a SIM (unsurprisingly), so I took it into the Verizon Wireless store and they gave me a SIM. The phone sat on the Setup Wizard with a dialogue box saying "please wait..." with a spinner, for about 20 minutes, then got to a screen with a "Phone Activation" header that says "There is a problem with activating your phone. Please restart and try again, or contact customer service." I click restart, and that doesn't solve the issue (it just does the same thing).
I've been wrestling with this thing for two days now. The guy at the VZW store called support, and they went through five different people who didn't know what to do, and finally they put in a request for support that apparently will be resolved indeterminately. The ESN checked out fine, and the SIM card is fine (we even tried a second SIM card). It can reach the servers fine (if I hold down the search button I can do a voice search and it browses the web as if nothing were wrong). Unfortunately, my phone number is in the air (it's been pulled from my old phone and won't hit this phone).
I was wondering if anyone had some insight on this problem.
Thanks!
Same thing is happening to me. I have to flash back to stock in case I have to go back to the store and figure this out. Crap. I tried different sim cards and she couldnt get either to work. Ok I flashed back to stock so when I take it in I dont have a problem but I cant get through the process because of no signal and it shows a date and time as december. Is that because the ee4 file I flashed was from december?
LOL data network issue supposedly. Network down.
I just bought a used droid charge and ran into this exact same issue. After a few hours of reboots and battery pulls, I held down the power key to turn off the phone and noticed an option to activate data networks. after turning on 4g, i was able to activate my device perfectly. Hope this helps someone.

i know someone who had an issue like that for some reason, he came to me for help, for some reason all we did was swap sims once activated, we swapped back and everything worked like normal after that

[Q] Sim Card Problem

I'm having a SIM card issue, but I'm not sure it's specific to the SIM or my phone. Here are the symptoms: my phone randomly loses all it's cell phone bars and 4g, and eventually says no SIM is seated in the device. It sometimes turns into emergency mode, but usually just shows no signal. If I restart the phone, everything comes back just fine for an indeterminate amount of time.
Assuming it was a bad SIM, I went to VZ and got a new one, but the exact same behavior continues to occur.
Any clue what this could be? I'm on 4.1.2.

No signal

Good day, today I dropped my phone don't know if it lost signal after this didn't notice until I tried to make a phone call but now there no signal, can't make or receive calls, I notice that at the bottom of the screen it shows my service provider name and next to it says no service so don't know it its hardware related or sim, do you think that if I reset the phone it might work again? Thanks. Right now can't test because I'm at work, but in general information on service it says disconnected

Flash stock with fastboot, if it's the same, it's hardware I'm afraid.
Thanks a lot did already, tried everything seems hardware related, noticed that it also lost nfc connection wondering rich part should I replace to fix it, if only has to do with antenna or the whole mainboard
The NFC radio and antenna are connected to the back cover. Try popping your back cover off and on again.

Thanks already did and nothing, could it be related to some other piece?
go to your dialer app and type in #*06*# and see if a number pops up (your imei number) (dont post the number here)
Did too, also the *#*#4636#*#* and checked if signal was turned on, tried sim in other phones works without problems, I noticed that nfc is not working too, guess it has to do with a piece of hardware as far as I know both antennas are in the back of the phone. Took it to service and they told me it has no problem physically, this is driving me crazy
Also checked that it has no reports of being stolen, imei seems correct and legit checked it also on a site to see if it's valid and its working, it starts with a 32.
My phone wouldn't connect to any network after being in airplane mode on vacation for a week, acted like no signal - empty triangle instead of bars. I called my cell provider (T-Mobile) and after a new SIM and a factory reset they did something on their end because my phone was trying to connect to a tower that didn't exist. I'm a little fuzzy on what they actually did, but it worked. I actually had to do it twice over a couple weeks before it stopped giving me trouble.

Hello
Hello guys, I am on the same boat as Valholy described.
My phone fell on the ground from my hands. When I took the phone from the ground... it was still working(it wasn't shutdown nor restart), I only noticed that there was no more signal. Tried to restart/shutdown, factory reset, different sim card but no luck at all... As Valholy described it shows provider's name on the bottom of the screen, but there is no signal yet.. It seems like hardware issue. Any recommendation to fix this issue?
Did you fix your phone yet, Valholy?
Thank you
bump...
any help please.
thank you

SIM not detected after dropping phone

Hello! I've had the ONO (A0001) for about 3 years and it has been more than adequate for my needs. It has had a few drops along the way, but nothing terrible. Was always kept in a Diztronic case with screen protector. Been running the Resurrection
Remix ROM (Android 7.1.1) very stable since the start of the year.
However, after its latest fall (it actually landed screen first!), I've noticed that my ONO has stopped recognizing the SIM altogether. I've tried reinserting the SIM card, network reset, rebooting, cleared the 'Phone' and 'SIM Toolkit' app caches, wiped cache in TWRP, but to no success. Interestingly, WiFi still works. Attempting to access 'Cellular Networks' from 'Wireless & Networks' to change 2G-3G-LTE returns "com.android.phone has stopped" at every attempt.
Has anyone every experienced this before and knows how to fix it? I have a sick feeling that this may be a hardware problem.

Hi @xFalcon1986 I had a similar issue for about one year. This may or may not help but for what it's worth, here is my experience:
Only my home network sim card would reliably work. Recently, I was traveling and once again my roaming worked for a few minutes before the phone gave me the notification: sim not found. I decided that enough was enough - I needed to figure this out or get a new phone. When I removed the problematic sim and compared i to my old home network sim, I noticed that there was tiny bit of curvature on the card. Excited about the potential, I bent the sim that would go unrecognized within a few minutes. Turns out, the first time I bent it, the side I made concave was the wrong one. After the first failed attempt, I pulled the card out again and then bent it the other way. It didn't work either and hope was fading. Just to be sure, I bent the sim one more time - this time further than I thought healthy for the sim. Turns out those cards are quite flexible! Once I inserted the sim, the network connection returned and remained for at least 20 minutes. It then went unrecognized and so I bent it once again and everything continued working.
It turns out that I need to bend the sim card once per week but besides that, my phone once again recognizes the sim.
I have no idea if you went to another phone by now but give this bendy trick a shot. The metal contacts might just have been bent a bit too much one way or the other while the phone impacted the ground. Give it a try and let us know how it worked for you. Cheers!

I have a similar problem. I wanted to activate the SIM. I didn't have access to the SIM card number for activation. So I removed it to read the number. When I put it back in I started getting "not found messages". Turns out something happened to the SIM card tray, and the card slid off the tray and was stuck inside the phone! I finally got it out by bumping the phone against my hand.
I went through e-Bay and located a replacement as the original appears damaged.

Hi! Sorry for the late reply but yes the solution is working great. Because of it, I'm still making use of my OnePlus One! I found that after the second week of bending, the sim card held the shape for about three months before I needed to bend it again.
Funny thing is that I initially also had my sim stuck inside the phone for some reason and getting it out was a real pain. However, with the bendy trick the sim had been working and I've had no trouble removing it when necessary. Hope you were able to figure something out. ?

Samsung SIM Card not working

Hello!
A while back I dropped my Samsung A71 in water and when I started it after drying it everything appeared to be fine. But after 2 weeks or so a problem with the SIM card appeared. The card gets recognized, and I need to enter my PIN, however, I do not have any mobile data, which obviously is a pretty severe issue since I cannot make or receive calls and texts.
The odd thing is that after 20-50 restarts, it suddenly starts working normally again. This makes me wonder, is this a hardware or software related issue and would it help to install a custom ROM. My phone is rooted since before so maybe there are some mods that could be handy to search for a solution.
I'm very grateful for any help!
Few months ago, I dropped my Galaxy S7 in the water, too. It had some very weird restarts so I teared it down, cleaned it up, then tied it up.
There were two cables I did not tie, thought it wasn't necessary, so when the phone booted, it was just fine, except the network, it was showing "Emergency Calls Only", sometimes shows "No SIM Card".
At first, I thought it was EFS issue, so I tried a lot of recovery methods, none did work, however LTE only mode could receive signal sometimes.
It took me a month to figure out that it was the cables I did not implement.
It's definitely a hardware problem, and it seems like it's just water stuck somewhere between these cables, or near the SIM tray.
