I have a problem where my Charge thinks I am always roaming. One other person in posted in this forum with this problem but had no responses and he is a one post wonder. Has anyone else seen this problem. I have sent this device to Samsung twice and it has not been fixed. They will not replace it. Verizon did some stuff overt the phone that was of no help. This does not happen if I put my sim in a Thunderbolt and it does happen if I put another Sim into this device. It has to be the device. Any ideas?
i think that I ran into this problem just the other day have you figured out how to fix it.
I thought that the sim was supposed to automatically update roaming.
I have tried flashing Roms over top using odin cwm and nothing has helped, i don't know what else to do.
What are you running on it (roms, radios, etc) and what have YOU done to try fixing it?

I was on Gummy charge fe 1.9.1 and a few days ago it put me into roaming mode. all the areas where i would have perfect 4g or 3g reception say i am roaming. I tried reflashing the gummy rom in odin and in cwm then i tried getting the new leak to see if the newest modems would fix it. Niether of those worked so i tried flashing the EE4 stock rom and that didn't work either. I didn't want to keep flashing after that because i didn't want to end up ruining my phone any mor. I flashed each of them a few times to make sure it wasn't just an error.
I wiped all data did factory restore wiped cache dalvik and even battery(i know that didn't really do anything useful but thought i would try it).
I didn't know what else to do so i figured i would leave it on stock unrooted and see if anyone could help me here before i called up verizon.
I also tried taking the battery out and sim for about half an hour to see if that would do anything but it didn't help either.
Is "data network mode" on your power menu activated? May seem like a stupid question....Also, can you make calls?

Yes i can make and recieve calls also i can send and recieve text messages. I did find out that when i go into a 4g area that it will connect so i was wrong about that part. Earlier i just assumed the 4g would act the same I just wasn't in a 4g area for a couple days because I had off of work. But as soon as I leave the 4g area it says that I am roaming.
This info may help solve the problem and sorry about saying the 4g didn't work. you know what they say when you assume you just make an ass out of u and me.
I am thinking that it is just the 3g antenna going bad or something because I saw that was happening to some people but I am not sure if it is the same predicament.
Thank you for the help so far though.
Oh yeah and also the mobile network is on If that was the problem I would probably be really upset with myself that i didn't notice. Although I have seen it happen when i went to verizon to get a new sim card after something happened to mine I ended up waiting there for half an hour for them to get my phone working only to find out the reason they couldn't get the new sim working right was because they had the mobile data turned off.
Multiple Roms, stock and custom, gingerbread and froyo. kernels radios, you name it. No problem with voice. Shows data roaming all the time and will not get data unless I enable data roaming in the settings. If I pull my sim out and put it in my Thunderbolt there are no problems. I also tried a different sim and the problem was still there. I have already sent it to Samsung for this as well as talked to Verizon.
Ever since I flashed GB I have not been able to get signal in my work (3 bars on stock froyo).
I used the stock modem in Valhalla.
Then I tried KF2....
Each time I go to mobile networks, it wont even recognize T-Mobile, only shows AT&T.
I went outside at work, searched again, and was able to register fine. I do not think it is an IMEI or hardware issue because of this.
I searched, but did not find much.... is this odd or common?
Anyone have suggestions for this?
Thanks.
I've had the AT&T thing happen before with some GB modems, but only if I am in an area with really really week signal (like inside my condo). I flashed the KD1 modem, and it does work a bit better.
With KD1, I can get 1, sometimes 2 bars if I put the phone in a certain spot on my dresser, and it won't jump to AT&T.
Nice, will try that one now. Coincidence that I had t-mo swap my sim card yesterday. I am on the phone with them now to see what they can do, if anything.
I'll give it a whirl soon.
Well, called T-Mo... they tried some things... no luck. Flashed a few modems... no luck.
Now, it is working. Maybe just an outage here.
Okay so I flashed a 920I stock image on my SM-920I and now my phone says it's roaming. It's working fine mind you, calls and all, but there is the R symbol.
If I turn roaming off, it says I can't use data. I'm confused.
So any suggestions? Tried flashing over a rom. No change...
You say you flashed a 920I stock image, did you flash the correct one for your country?

Perhaps the phone is telling you something about your course in life; that you are roaming when you have a destination you should be working towards.
Metaphysics aside, try re-starting the phone. If that doesn't work, try letting the battery die all the way, and then allow it to charge. These two practices have solved many of the strange problems that i've had with telephones over the years. If the problem is not yet solved, take it to the gentlemen behind the counter. They will alleviate your concerns with some belittling solipsistic response, but they usually will fix your issues for a small fee.
I think i saw this issue the other day. My phone is completely stock. I can't remember how i fixed it though - either it fixed itself or i just went into airplane mode then out again. Either way it hasn't reoccured and it was only brief..

Yeah I flashed the one for my country. Then I tried others. The thing is the phone seems to be working normally.
I don't think it is truly roaming, but the little R is bugging the heck outta me.
I wish you could remember how it was resolved. Driving me nuts
Just thought I'd post my solution here.
Kept flashing until I got a ROM from a different country (!) that worked.
Had an older bootloader etc but hey, no more stupid roaming.
So the phone updated itself and it's back to roaming lol
Again solved my own problem by extracting and flashing the older modem...
I believe the last t-mobile OTA update broke my 4G/LTE, was working fine before but now nothing at all. Only Wifi works. -- I took it in store and we did a new sim, some resets, nothing worked there, was going to warranty RMA the device but there's a small crack at the top of the back glass which voided the possibility of doing that.
I'm very experienced with Root, I've done the Note 3, 4, and 5 before so I'm comfortable doing that. I think a root and flashing... pretty much anything else might fix it. Am I being stupid? What do you guys think, any thoughts would be appreciated.
Sorry if this a easy known issue with an easy fix, that'd be great and I don't think so, but I wouldn't exactly say I'm in the loop as far as the S7 goes.
Thanks, hope to hear from anyone soon!

Do you get 2G "Edge" service? or nothing at all?
You're not crazy after updating I lost all cell service. since downgrade isn't possible i had to flash 930U firmware, fixed that issue and performs much better...there's a thread on here with more info...hope that helps
Sorry for the slow response guys, thanks.

Oh wow ok, this is actually good news for me. Can you go into a little more detail on what you did. Maybe link me to the thread about it and/or the download to the firmware. Thanks!
This happened to my dad's S7 as well. Was working fine after update and then suddenly nothing except wifi.
The Nov TMO update has great battery optimizations.

I am also having the same issue with my wife's S7. In fact, exactly the same as the OP, including the warranty void due to a small crack on the back cover. Performed the OTA and everything seemed ok for few hours afterwards. Woke up the next morning and discovered no network, no signal but yet WiFi functions fine. I went through all the initial checks and resets and nothing worked. Swapped Sim cards, uninstalled some apps and yet nothing until the last app uninstalled. Mobile network became available as soon as Milk Radio finished uninstalling. I know that this is by coincidence but hooray.... And of course a few hours later, Error Registering On Network. Factory resets, hard resets and nothing. I'm out of ideas and luck. And you gotta have a lot of luck with T-Mobile insurance. Any ideas or help with this issue would be greatly appreciated.
What can T-Mobile S7 flash? Anything?

Most of the Info is here also the firmware and tools needed, there is also a guide.... I had to sim unlock my phone before proceeding
Well, I updated to the most recent PK1 and I'm still getting network errors. Status, radio off, network not registered, signal is dead 113dbm. Looks like I'm going to pay the $175 insurance deductible and hope for the best. Best of luck for the OP. Hope you figure it out.
On my S7edge the new update drastically hurt my signal for 4g.. I ended up flashing the U firmware and am using the previous tmobile cp file (PIA) on my phone and got back the signal that I had lost.. This could be a possibility for yall too... Install the 930 U firmware and replace the U cp file with the tmobile PIA cp file for your device and you should gain back your network signal.. I plan on trying this on my sons S7 over the next day or 2 once I get all the files downloaded...
I need some help here, weird Verizon signal issue. So I got my U11 on Thursday the 22nd of June. I tested out the stock rom, all working fine, signal working fine too. Then I unlocked the bootloader, put twrp on in system RO mode, put magisk on, then put viperU 1.0.0 on. Viper/magisk and everything was working perfectly, I still had signal, could make and receive calls, send and get texts, wifi was all good, everything was good until Friday afternoon. I think it had to do with me trying to install the ota 1.1.0 viperU, but my signal dropped, still had 4g but that was touch n go. I tried to reinstall the ota because as far as my settings said and knew, I was still on 1.0.0 and when it checked for updates it found 1.1.0 again. After that 4g would work for a moment at boot then die, and there was no signal for calls/texts, that has the signal bars full with a slash through them. I tried fresh installing viperU 1.0.0, no change. I tried every combo in the test/advanced settings, changing the preferred network mode and ims settings, turn the radio off and back on and it would see verizon and try to connect, sometimes seemingly getting signal and changing the signal bars and getting 4g, then losing both. The status msgs on the advanced settings page would go back and forth as far as registered on the network, so I went to verizon and tried to get a new sim, the new sim didn't change anything, BUT a weird thing that happened is when the vzw rep went to the back to get me a new sim and activate it my U11 got signal, both 4g and call/text and I even got a msg, then it died again a moment later. So next I tried completely restoring and relocked my bootloader and installed the 1.11.617.4 RUU for my OCNWHL using htc_fastboot which it did perfectly fine, but still no signal. The bootloader says relocked(L) and software status: modified. Shouldn't it say official again since I flashed the RUU? I have tried reseating the sim and rebooting multiple times too. Oh and one more thing I noticed, my WiFi is touch and go now too, it'll say connected but websites fail to load, apps fail to download, etc until I turn off and back on my phone WiFi. Any ideas guys/gals on how to get my phone connected again? I just want to be able to use my new U11! Thanks in advanced!

All I can say is a lot of people are having problems with Verizon, me being one of them. I've had the phone almost 2 weeks and still can't get it working. I've talked to HTC and Verizon so many times and they say it's being worked on.
same here. Spent a couple days with near constant contact with Verizon trying to figure out out. Got in touch with HTC and it seems it may be a firmware issue. I can verify with no doubt that it's not the sim though. I've put mine back in my old phone, it worked. I put my daughters in my new phone, it failed to work. I even got a new sim for mine, but no luck. Multiple ROMs, multiple RUUs, and multiple factory resets, and wipes. All we can do is waiter, and pester the hell out of HTC to get them to hurry up.

It's so stupid that they don't even do testing before putting it on the market.
If either Verizon or HTC would come up with a simple software update to enable CDMA and all LTE bands, that would solve everything. The problem seems to be that Neither is putting much priority on it.
BTW: Since the U11 works with Sprint, it has the CDMA and LTE bands built in. They're just not set up to fully work with Verizon yet.
Exact same problem.
My unit is going back for refund tomorrow. 4 hours of work trying to get it going and I'm done. HTC blames VZW, VZW says it's hardware. $650.00 paperweight. No thank you.
I'll reorder if this get straightened out. There are hundreds working just fine on VZW.
Seems to be just a few of these that wont stay connected.

I was starting to lean towards firmware today because of the wifi going in and out. Seems like to get an app to download from play I have to search it, start the download, turn off wifi, turn it back on and then it'll download, yet updates download just fine. Fandango app won't load movies or anything. Etc. So I'm wondering if it's the system or radio...
stock U11 no issues on VZW
I took my sim out of my VZW line to test it out on my U11. I did some speed tests before I took it out. I inserted the VZW sim into the U11 and it booted up with no issues. Received LTE and ran speed tests and they were similar to the other device. There was VoLTE available and it was stable but I didn't make any calls with it. So just sharing my experience with my stock, Unlocked U11. I put the Tmo sim back in but it's good to know it'll work. It seems like some are having issues from the get go and some are having issues after modifying?

That's what's so screwy about it. On mine, I get WiFi flawlessly, and I even get mobile data, in 4g even. I just can't talk, or text. Before that, I could text, but no data, and couldn't talk. It's got to do with the way it's using the radios being screwy. The hardware functions, I've had full connection before, it lasted about 2 hours, and sounded amazing even.

Short answer: Yes. I noticed mine stopped after installing a ROM on it, but it was not the first one (test driving to see which I liked on it best). Others have the issue even with it locked still. I think the ROM flashing was more a circumstance than the cause in cases like mine. I even RUU'd back to stock, did factory resets, and tried other SIMs. It also seems to be only Verizon, unless someone on another network wants to set me straight.

I remember an issue on Verizon and the M9 that after flashing a custom rom, you stood the chance of loosing VoLTE. It did not happen to everyone and did not happen all of the time. I flashed custom rom for months and then one day, boom, VoLTE gone. The only way to get it back was to get the phone replaced. RUU did not work to get it back. Sounds similar to what is going on now. So my question is has this problem affected anyone that has not unlocked the bootloader yet?
I just checked the M9 Verizon section and looks like they did find a fix without replacing the phone. But I think you need to be s-off. Interested if this could resolve any of these issues here.

I will be trying this later today. Good ol' @dottat
If we get s-off we can probably safely flash roms without magisk n still have volte n even a more stable radio/system firmware, if dev's make it happen of course. Or am I wrong, I don't mind having magisk, I just want to be able to root n customize my phone with it still working as a phone n not a fancy calculator or wifi only device haha. I'm debating getting a replacement from HTC until the firmware stabilizes at least, then I'll mod some more. Cause mine was working perfectly fine until I tried to put viperu 1.1.0 Ota on it.
I just noticed that when I drag down and get the quick settings into view there's a note in the top left that says "the sim card is missing or not readable. Insert a sim card" and that doesn't go away even when the occasional notification that says "sim card inserted click here to finish setup" pops up.
Was fine for a couple days - now suddenly today only getting "roaming" service. Manually trying to connect to VZW fails and says my SIM isn't allowed access.

The full story is in the op of this thread, but it started about a day after I got the phone, started with only voice/text going out, then lte dropped too so now my phone is wifi only. R u on stock or have u unlocked ur bootloader?

Ah sorry, didnt notice you were OP. I have unlocked but was running stock OS with Magisk (no other mods, I just wanted root). Noticed that turning of VoLTE in phone settings killed connection, so I was able to toggle that off and on (+airplane mode in between) to usually resurrect connection. Now nothing is working. Going to do a full wipe now to see if it comes back.

No worries haha. My signal today is intermittent, I'll get bars but can't call because when I try 4g turns off. In the HTC test settings, when I have bars it sees Verizon network but not my phone number, where as when I don't have bars (bars with slash through them) it sees my number but not Verizon network. For u to see this menu type *#*#4636#*#* in the dialer. My VoLTE is activated in settings tho.
Factory wipe didn't help either. Doing RUU now. This is so ridiculous. Also I accidentally deleted my backup, oops. Le sigh. This thing will probably be going back. Sad. I was loving the phone.

Bruh - go in menu -> Phone Info -> Turn Off Radio
Select "LTE Only" Select "WCDMA/LTE"
Turn radio back on.
Fixed problem instantly!!! Thank you SO SO MUCH!
edit: MMS doesn't work, but SMS seems possibly ok? not sure.
edit 2: WCDMA/LTE is the magical answer. All seems working now.
