Sim card not allowing connections? [Help]

Flashed a few roms on my phone and never bricked it whats so ever. It shows the IMEI, how ever it doesnt match the IMEI it have on on the back of the phone. The phone came with 2.2.1 Froyo and i upgraded it with ODIN using KJ6 2.3.6 GB rom. I can connect to wifi and such. It's not the sim card cause it works with all my friends tmobile phones. I get bars on the phone with the sim card in it. But when i attempt to make a call it says "Not registered to Network" i went to Settings>Wireless and network>Mobile Networks>Access Point Names, i went there to do the APN Manually i tried setting it to Default and it didnt help either.
Anyone know's how to fix this?

Disconnect (remove) battery, leave for ten minutes, reinsert battery and sim.

Thanks for the quick reply, Does it have to be exactly 10mins? Not to sound like an idiot.

I'd say at least 10 minutes, going longer won't hurt.

Alright , Im giving it 20mins. Hopefully it works. It's been too long and i'm starting to give up on this phone.

Still having a problem, You know any other solutions? I don't wanna have to pay for a new phone lol. If you do can you have it in FULL DETAILS. Cause i want to make sure i have have every thing correct.

I got all day to try to fix this. I don't want to try reflashing things cause i don't know if i can mess it up or cause more problems.

So.... you have flashed a few ROMs..... meaning you have at least ONE nandroid back up from when the phone worked?
If you do... you are good to go. If you don't..... good luck to you. You have what sounds like a generic IMEI.

Well i don't, didn't know i have to. So in other words it's impossible to get this phone back on?

I had the same issue with my phone, it just wouldn't stay on Network, and the SIM would go back and forth from being recognized or not. I flashed back to stock and it still didn't work. The ten minute battery pull was suggested in another thread and a few people swear it works. Mine played up before this was suggested so I never tried it.
I had the same thing happen with my wifes phone and all I could link it to was the Kj6 modem...see link below. I reflashed the whole ROM and it came back.
With my phone I just called T-Mo and told them that since I upgraded to 2.3.6 via Kies that my phone wasn't working properly (Technically true, but a little stretch). I flashed Bhundvens 1click to stock, factory reset, etc...etc... then paid $20 and got a replacement phone via UPS in about 4 days.
I not saying you are having the same problem as I did, but it sounds very similar.
As a side note, the replacement SGS4G (refurb) they sent me absolutely blows my original handset out of the water when it comes to signal strength. I get solid 4G speeds of 5MB+ in my house, where before I only got patchy edge. I was amazed at the huge difference in performance between two supposedly identical handsets.
I hope you can get this remedied without an exchange, but you should be able to get a new one for $20 as a last resort.

Back ups are suggested all over this forum. Now you know. It is not impossible... google 'generic imei' and look at the dozens of ways people have had success and failure trying to remedy it. There are a ton of threads in the SGS 4G forum alone.
And whether you fix it or get a new phone... make a back up of your efs folder FIRST thing along with a nandroid back up. It will save your ass if this ever happens again.

Maybe download GPS aids from the market. It has a "hard reset" option. Not sure it will help but worth a try

Cannot Connect to AT&T Network (Neither Voice Nor Data)

For some reason I cannot connect to AT&T's network for voice/data. I had been running MIUI for about 3 months and all was good. I came back from a trip Thursday and the phone wouldn't find a network after turning off airplane mode, but rebooting seemed to fix it. However, today I cannot get it to connect at all.
I have tried:
Wiping cache/davlik cache
Fixing permissions
Tried searching for a network operator through settings->mobile network->network operators, got nothing
Wiping user data and switching to ZEUS Build 6
Tried searching for a network operator again
Went back to 100% stock with GTG's Ultimate Unbrick
Still nothing for network operator under "Available networks" (Default setup is greyed out)
I'm going to guess either my SIM or 3G chip burned out? I was using the phone heavily the past few days with a ton of GPS stuff to get around Atlanta and it did get pretty hot on the car dash. I'll try taking it to an AT&T store tomorrow (ugh) but am open to any suggestions before I do so .

There are a few options I would consider:
1. Go to the apn and set up a new apn and save it. Select it and then reboot. There are a few floating around. Check my how to thread in the q/a. I posted one there. Make sure you create one and then save it.
2. Try flashing a different modem.
3. Take out the external micro sd. Back up your stuff from the internal sdcard. Factory reset from in the ROM. Warning: a factory reset from within the ROM will erase EVERYTHING, including pictures. Make sure you save everything first. Reboot. And if that doesn't work, odin with a re partition pit file or use one of the heimdall 1-click and then do a reset again.
4. Possibly remove the Sim and clean it. I've heard the Sim socket is very fragile and breaks easily. Use caution. You can always have the att guys do it and let them break it.
Gl

he said he did try flashing another rom and odining back to stock. if that doesnt work, nothing will. hopefully you still have a warranty.

Already restored to stock (and again from within the stock rom)... Forgot about my pictures :crying:
Tried I997UCKL2 and I997UCLB3 modems, with and without custom APNs.
Tried cleaning the SIM
Funnily enough I do get service bars (4/5) after the phone has been on for about a minute, but no HSPA+ icon and still can't make calls/MMS/internet (calls are about 5s of silence followed by an abbreviated dialing tone, then "Call Ended"). Yup, I think it's borked... Guess it's time for an S3! Thanks for the help though.

Imei messed up?

Haha yep... I just dug out my old old phone (LG CU500 iirc). Found the charger and made a call. Seriously old school but at least I'm sort of connected until I can get my Infuse sorted!

Sorry to hear about your pictures. I tried to warn you.
The last thing i can think of is to leave your battery out overnight. And then put it back tomorrow.
It sounds like it's hardware related though.
(Different ROM like miui and zeus have their own custom build.prop ril settings and apn. These potentially can mess with your phone connection if the partition messes up.
I wanted to make sure it was not a partition screw up. A double flash in heimdall uckj4 or uclb3 with boot loader checked or one of the Odin un-brick using a pit file would have clear this. Sounded like you did this already. Another user have reported clearing their efs in odin. I would only try this if you have backed up your efs position, either in root explorer or zen tool kit.)
Again, sounds like hw...

Well when I transferred my sim to my old dumb phone I left my Infuse off (about 3 hours). I just tried it again for kicks and miraculously it works perfectly now! Now I get to reinstall everything again (yay...), but I'm wondering if my sim slot is on its way out or something... Not sure why it would suddenly start working again.
Oh well, time to try out Zeus (MIUI was a little too buggy for me).
Thanks again all... hopefully it doesn't die on me again!

Good to hear.
If it starts to act wonky again, try a different battery. It is possible the heat you described may have damage the lithium cell. Idk..
Ebay has them for about $4 free shipping. Look for a usa shipper...2-4 days

For some reason this happens to me sometimes. I'm unsure myself. What I do to fix it is turn data on and off and then reboot. I do that a few times and then it starts working.

So after three different roms, several factory wipes, and all sorts of voodoo magic, it was a bad sim card.
Shame... I kinda wanted an S3 .

Calls and texts not coming in at times.

I'm using the International version of the flat S7 on T-Mobile. I've been having this problem for about 2 months now although now it's happening much more frequently. I contacted T-Mobile about my problem, they went over some stuff in the sim card. Such as updating something, checking my area for interruptions, running a diagnostics on my phone. They said everything was fine. Although the problem kept continuing. They sent me a new sim card free of charge in hope of fixing my device. Even then that didn't help, my calls and texts still randomly do not come through. There are times it does and times it doesn't at all. Now I'm wondering if I have a faulty device? Is there any more options I could do to fix this problem?

Tried a factory reset?

Hi, I have tried S7 dialer app (SecContactsProvider.apk & SecContacts_M.apk - deodexed) for my samsung device (J2 2016), It worked fine but suddenly it stopped posting missed call notifications in call log and elsewhere. It becomes very difficult to track who called since there are no traces of caller. Really looking for fix for this.
Thanks.

MMS Not receiving unless using HTC message app

So for the past week I have been using gboard and android messages to be able to send gifs, bitmoji, etc. All of a sudden for no reason I can't receive any MMS at all using any other message app than HTC messages. Has anyone else seen this? I have tried textra, verizon message+, etc. Once I uninstall the other apps i can get the messages again, but only with the HTC app.

Known problem with android.
https://textra.uservoice.com/knowle...-mms-timeouts-no-mobile-data-mms-send-failing

Again..
So the link above is for android 7.0... I have fixed the 7.0 problem in the past and did the whole new Sim activated on a newer vzw phone and had HD voice ect added and restarted my u11 with factor my reset. Fixed my mms issue for 6months until recently. Textra and any other app that isn't htc, fails to recieve mms. I have another u11 on 7.0 and it's not being used (long story) and put my sim in it and tested. Still no mms.
I did change my plan around the time the problem has started to occur again. Today I'm takin both u11s in and seeing if I can get mms to work by activating a new Sim. I'm frustrated cause I dont like htc sms app.
Anyone else having problems? Maybe the Sim card is just a bandaid?

Do you have a stock rom back up ? If so back up your current rom and data then restore the stock rom back up then boot it and let it update apps then reboot to recovery and save your updated stock rom to a new back up then restore your back up that you were originally using and it should text fine. I said to update apps and do another stock back up so you have a new updated back up for future fixes. I have had to do this a couple times but its usually after flashing things like I did through magisk I did the viper4android and it broke texting and data but doing this always seems to be a fix for me and others. Its not permanent fix but it will get your texts and data working again until you flash something again.

That is kind of odd as usually people on stock rom do not have these problems its usually just the people unlocked and on custom roms and flash any mod and the problem rears its ugly head but doing the fix I listed is usually a fix or RUU worse case and your fixed.

Ya, it happened randomly. I haven't done any mods to this Phone cause it works fine for me the way it is. It'll it was a vzw branded phone then I would put a custom ROM... Hate bloatware. If anything, I might tinker to get bands 2&4...Maybe.
But I'll try a factory reset tomorrow after work... So assuming I should remove sim before hand?

I actually have the same problem with my HTC U11 that's on Verizon services. I posted a new thread about before I seen this one. My problems started a week or so ago. I was using Android Messages at the time this stopped working. I have put my SIM card in 3 other phones with the same result. I then put my wife's SIM card in my HTC and was able to receive picture messages on the HTC using her number. So that said to me it's not a phone issue but my SIM card. I got a new one today and activated it using my G5. I was able to get picture messages on the G5 put the new card in my HTC and it was a no go. It's weird that her card would receive mms messages on my phone but my old card or new one won't. And now that I've put the new one in my HTC I can no longer get picture messages on my G5. I also noticed that on the G5 settings i was no longer able to turn on video calling. It said that service was not turned on and needed to be enabled on my plan. My wife still uses her G5 and it will let her turn on video calling. It's almost as if this problem is attached to my phone number and something fishy is going on with Verizon. Seems weird my new card worked in my G5 then lost that ability after putting my card in the HTC.

Screen on/off uncontrolled when SIM card inserted

Hey guys
My screen is uncontrollably on/off flickering when the sim card is in. As soon as I push the sim card out, phone is usable as usually. Has anyone ever heard of that? Cant find anything in Google.
Thanks :good:
Edit: Factory reset fixed it - no idea how that happened. Phone was stock, not rooted, nothing special been done yet. Weird.

i have the same issue but my screen doesn´t work even without the sim card. how did you fix it?

Hey,
In this case I would try to flash the stock rom again.
with this tool http://api.en.miui.com/url/MiFlashTool
here is an instruction https://www.technobuzz.net/flash-miui-fastboot-rom/
I had to do it for another issue afterwards. I chose the fastboot ROM, worked fine
