[Q] can you help with loss of signal - Samsung Epic 4G Touch

hello...i bought my sprint sg2 and had it activatde on verizon. i didnt feel comfortable doing it myself so i paid a guy on ebay to do it remotely. shortly after i noticed i would lose the signal. I would have the 4 bars with a triangle then it would go to the circle with the line through it. i rooted it using a method i found here that wasnt suppose to change anything other than rooting the phone. i contacted the seller and he did something to it; said it was fixed and blamed it on me rooting the phone.
the phone is still rooted but i havent done anything else and im still having the same problem. my gf called me several times and the phone never rang, i was sending her a texts around the same time so im not sure if thats a problem with verizon or not.
yesterday i couldnt keep a signal. i would have to call her back and would experience the same problem with my signal. this has occurred in places where i normally get a signal.
im not sure what to do...and help would be appreciated. do i need to change a prl or something?

Try different modem, if you have rooted your phone why don't you try custom Roms. They are far faster n all bloat free.

Thanks for your reply. To be honest Im scared. I had a captivate and had no problem doing it but the thing with bricking the phone seems to be more prevelant. also i was under the belief that if i installed a custom rom that i would need to reflash it to verizon....and i dont really want to pay the guy again

Cannot receive SMS from AT&T after root

Hello all!
I've had this issue since I rooted my phone (with NAND unlock using Toast's method) back in the beginning of June. I noticed this issue IMMEDIATELY after rooting since my girlfriend is on AT&T. Recipients on AT&T can receive my SMS just fine, but I cannot receive theirs (I have tested multiple phones on their network)! Other carriers seem to work just fine as I have tested most of the popular ones although haven't tried T-mobile, could it be a "my phone versus GSM" issue?
I have wiped and factory reset my phone numerous times, used multiple roms including the rooted stock 1.32-1.47, OMJ's 1.4-1.7, and currently am on Baked Snack 9.6. Out of an act of desperation, I accepted the 1.47 OTA update before root with no avail. After all of this I have noticed one thing staying the same... The PRI Version 1.34. I know there is no current way to update this back to the stock 1.40, and too be honest am not really sure if this could even be the underlying cause of this issue because what does roaming have to do with receiving SMS on my home network? I've had multiple people tell me that they have had no such issues, and searching the boards shows me that this is definitely an isolated issue.
If anyone has any advice, information, or even has this issue as well please let me know! Any help will be greatly appreciated!
Call Sprint, sounds like a network issue, not a phone one.

Well, after several phone calls and tickets later, I have now found out that the AT&T messages aren't even hitting Sprint's gateway (the front door of data). It's odd because the tech rep is able to see my messages out, but not able to see the ones sent back. This leads me to believe that it is in fact a network issue, and has absolutely nothing to do with my phone. He clarified that even if my phone was broken he would still be able to see the messages at the gateway, but they aren't even getting there. There is nothing more that Sprint can do because they can't reference something that doesn't show in their systems; so I'm being forced to call AT&T... I have already gotten the run around from both sides stating, "well it's definitely an issue on their network".
I'm not really sure what else to do, it just seems so strange that the very same day I rooted my phone, I stopped being able to receive their messages. The only thing left for me to do is try and get a replacement phone? and if I do that, do I root my phone again and risk being burdened by this issue again? I know one thing's for sure, after having a rooted phone for almost a month and a half, there's no way I'm staying stock!
Getting a new phone won't help you, it's definitely AT&T's network, or whoever owns the bandwidth connecting their (AT&T's and Sprint's) networks. Simple as that.

Thank you drmacinyasha on your quick replies!
I'm hoping to get my girlfriend's account information soon so AT&T will actually help me; I'm just worried that they will say the same thing Sprint has told me. I know it's as "simple as that" to state where the problem obviously lies, but I'm not sure how simple it will be to get a hold of someone who will actually be able to fix it.
My girlfriend is able to send SMS to other people on Sprint just fine, so I'm confused by the fact that this has only happened to my number.

Sim Card Removed - Restart/Reboot Phone

Hi there
i own a galaxy S3 TMobile version for 2 months now.
I recently update on last rom and since then i am getting the following error.
Sim card removed. Replace the sim with a valid sim and restart/reboot the phone.
I am not really sure if i wrote the message exactly as it appears but thats the meaning of it.
I have unlocked the phone to use it on Greece.
I have the same sim on it, since the beggining.
I didnt had the problem before the update. And for sure the problem poped up some days after the update.
When i see that msg the most of the times (if not always) data is enabled.
I should also say that when i see that msg the phone is just sitting untouched. Phone has never dropped or anything like that.
For sure its annoying.
When i restart phone sim is working perfectly...... ..
Has anyone heared about it? Anyone who faces the same prolem and found a solution?
I tried to google it ut i came up with no answers...
Any help is welcome.
Thank you in advance
have u tried a different SIM yet?

I had the same kind of issue on my previous phone. However, there is no data on my phone that I had to reboot my phone a few times to establish data connection. Secondly, sometime I missed called. Replacing SIM card may not help either. A few people had reported the same kind of issue on T-Mobile Support site.

I tthought I was the only one plagued by this issue..
I have this same issue. It usually happens whenever I lose network coverage......it happens repeatedly.. This issue started happening after I updated to jelly bean...ICS had no problems..
I have changed my sim 3 times, installed several touch wiz custom ROMs, changed my base bands and kernel...The issue remains prevalent after all these..
The only way I have been able to resolve this issue is by switching to an AOSP ROM like cm10 or paranoid android rom
I hope a fix for this issue is found soon cos i am tired of restarting my phone everytime i lose network coverage
I have attached a screenshot showing this
replacement sim ractified the problem

I had the same problem the other day when I was driving home from work. I think it happened when I went from 4G to 2G coverage. And also, when I'm in 2G coverage, signal fades out completely and comes back on 10 secs or so later. I went to Tmobile and replaced my sim with a new one and I had no problem of such ever since. .. at least so far so good.

Believe me I have Odin end back to stock n the issue still persists.....changing sim cards is only a temporary solution....
The problem always comes back especially if you always in an area with no network signal
Warranty exchange! Samsung should replace it. Say won't read sim card. Or tmobile

It seems that it happens when the data signal is bad.
Yesterday i had to reboot more than 3 times inside in a 4h period.
Wth........
First & foremost,
How did you "unlock" your phone? Did you mess with the NV data??
Or were you a good boy & had T-Mobile do it for you?
It sort of sounds like T-Mobile may have disabled your SIM card altogether....which may happen if you screwed around with the NV data.
If it was properly unlocked by T-Mobile you should be able to stick whatever SIM card in there now. Easy to test, go down the street to your nearest Greek mobile telecom store & ask if you can test a prepaid SIM card in your phone. Assuming the GSM networks are to some degree similar to the US T-Mobile networks, you should even be completely in good shape using local GSM service.
*IF* you get the same issues with the local SIM card....well screw it then. Go protest in the streets about the austerity measures in effect at the moment. Or just be a lazy Greek bastard & demand 14 months salary paid, require retirement at age 50 and lastly *NEVER* pay property tax on anything.

Besides, you're in a marvelous country full of great food, drinks, parties and oh yeah nice women too. No Yiayia's tho.

Well i have unlock the phone through internet. I had no issues for the past 2 months at all and yes i am using a local sim card from the beginning. The problem came up with the last upgrade!
Besides that i have a backup of the nv data but i am pretty sure that isnt the problem.

LOL? What is that? Everyone around the world is talking about the Greek people and have no clue of what it really happens. I work 12-14 hours per day including weekends.... i pay more than 600 Euros on taxes per month and i ll never get those money back since retirement is at 70 yo!!! Most of the people are like this. Foking politicians and goverments who have been stealing money for so many years. That was the problem and not the people!
I wish i knew why you mention all these!
sim card removed
I'm having the same issue with my s3
I tried to unlock it using this method
http://forum.xda-developers.com/showthread.php?t=2014982
I'm not sure if it worked, but perhaps messing with NV data screwed something up??
I upgraded to jelly bean 4.1.1
I tried cleaning the contacts on the sim
I replaced the sim at WIND
I even tried a factory reset
Nothing worked so far.
Has anyone figured out why it's doing this? Is it hardware related? software related?

In the same boat as you...I thought i was the only one..
on wind's sgh-t999v Galaxy SIII ... unlocked it like you did, and I'm getting a no sim card, restart required error, get it about every 8 hours or so..
i ported my number over too, but it says under "my phone number" in settings.. has a completely different number than what I'm currently using.. not sure if that has any effect..
tried restoring to factory settings too.. nothing seems to work...
if anyone has any info that would be much appreciated...
From the cold boot and after the error message goes away, does your phone has data connection?
I got the same error message on my previous phone. However, it would not establish the data connection.
Watch this video to see if your phone behaves the same way --> http://www.youtube.com/watch?v=GRB-cPD-JlE

mine doesn't do that, I have a data connection almost instantly where I have a signal
the error goes away after a reboot, but the error stalks you, and you never know when it's going to strike..
sometimes when it's in my pocket waiting for a call, while i'm driving with a headset on, at night while i'm asleep
for me, it isn't consistent, but it eventually happens..
I intend on taking it to the repair center for wind next week once I get back home (with the family for the holidays)
I don't think this issue has anything to do with if the NV data was messed with because my husband and I have the same phone purchased the same day 6 months ago. We both get the same error message and it's does not always happen at the same time so I am not sure it has anything to do with the network either. When it happens to him, he tells me it's happening but it does not happen to me. I googled the error because it is annoying. I will guess now that this issue has to do with the Gallaxy s3 and the update to the firmware. I can't wait for a better update.

Hi again
Since I know that there are a lot of people facing the same problem I thought it would be nice to give the solution on this kind of problem.
It seems that when you update via kies (of course on stock roms) something goes wrong. Recently I install the latest rom using odin and except that I found so many new things that I couldn't see before I also had no sim problem again.
So I am pretty sure that this kind of problem appears due to the kies updates. And from what I saw there where more.
If anyone else try the same please let me us know if it worked.
Good luck to u 2.
Btw yes I had that problem when the data signal was almost 0... Maybe 0.... Only then!

First of all I want to ensure you that has nothing to do with the way I unlocked the phone.
Second nv data is untouched.
3rd the problem came on after an update.
As I said after a clear fresh install without ba kups etc, starting from 0 the phone works great again and also there are options settings etc that I couldn't see before. Crazy but real. If anyone else do the same thing and make a fresh install with the latest rom he will agree with that.
So... As you said we make good parties and have nice womens... But how you will caption those moments those special (girls) moments without a nice camera (phone) ?
Have a good day hehe.

For those on the SGH-t999v version of the phone... the reason you are getting this "no sim error" is because of the firmware update to 4.1.1. I've sent my phone in for repairs and the best answer they could give to me was that there's an issue with the current jellybean.. not sure about the SGH-t999 standard versions though...
Unfortunately, I've had to revert back to ice cream ....and guess I have to wait till Lime Pie (OS 5) comes out...
The issue is not the NV data as I have used that method to unlock my phone as well.
Thank you for your replies. I'm relieved to know that it is not the nvdata menu that caused this problem.
I sent my phone in twice now and I've recieved it back for the second time today.
The first time resulted in further Sim card error messages. I'm keeping my fingers crossed in hopes that it does not appear again.
If op would be so kind to lead me to the right direction as to how to use Odin, I'd greatly appreciate it.

[Q] Missed texts and calls for 2 days.. how can I determine cause?

Like the title says people called and texted me the past 2 days and I didn't realize until 5 minutes ago when I received several texts at once. My question is how can I tell what caused it? AT&T, hardware, or software (custom rom, tweaks, etc?)
EDIT: I texted people during this time and they received them but I did not receive their replies until just now
My old galaxy Note used to do the same thing. I talked to ATT but they said everything was OK and I flashed multiple ROMs to seek a solution with no avail... Even did it with stock roms... Flashed different modems and nothing... So it might be a phone hardware (antenna or something of the sort) I got rid of the Note and got my SG3 ...if its still under warranty get it swapped...
Its the only advice since it happened to me as well and hasn't happened in my S3 at all
Sent from my SGH-I747 using xda app-developers app
Anyone else have any ideas/feedback?
Happening to me too!
I have the same issue. The only way I know it has happened is when my family email's me and asks why I am not responding to their texts or calls. I have spoken to AT&T twice now. So far they had me go get a new sim card and claim they have sent things to my phone that *should* cure the problem. The last call was yesterday and I am waiting to see if it is fixed but I would bet against it. My phone is still under warranty and it if happens again, I will swap it out. They also wanted to get me to upgrade to Jelly Bean which I already have done hoping for a fix.
I have never had to swap out a defective phone. Will they send out a replacement and allow me to keep this phone until the replacement arrives or must I send mine in first? With this phone using a mini sim card, I do not have another phone I can use during the shipping time.

[Q] No Service.. anywhere.

So my wifes phone no longer likes to be bothered with phone calls or text messages. Her phone has been running flawlessly since we got it and about a month ago she dropped it and cracked the screen. It was too the point where the touch screen wouldn't respond to anything and we had to have it fixed. She took it to one of those places in the mall and they said they could have it back to us in a week or so. Once she got it back, she has had constant issues with not being able to connect to the Sprint Network (only for phone calls, data and wifi still work fine). She often roams but still with very little signal strength. She tried a factory reset, as per the Sprint Customer Service suggestion, and it did nothing. She had remained Unrooted up until this point and I finally convinced her to come to the dark side. I did the root, installed TWRP, and flashed her with Optimus DE. I got no change. I reflashed her Radio. Still nothing. I am at Wits end on this one and ask for some guidance. It would be much appreciated
(ps. She doesn't have insurance on her phone.)

It sounds like the antenna may not have been reconnected upon completion of the screen replacement. At this point though I would attempt a PRL and profile update for the phone. If that still doesn't work I would take it back to the repair shop and request they check the antenna since it was working before the repair.
This ^^^^ And also, Optimus DE can have weaker signal. Try a Stock ish ROM. You can also try going to Settings>About>More>Mobile Networks and check CDMA. It can help too.

Thanks for the suggestions, I will let her know about the antenna issue, that sounds like it possibly could be the case. I tried Stocktimus as well as Optimus DE, I just forgot to mention it. I chose the most basic (closest to Stock option) it had.
Also, I tried the PRL and Profile update and it had no change in signal.
Thanks for the replies.
