I have a SCH-i605 on Straight Talk network using Verizon towers. It's rooted and running Bean's rom. For the past month or so, I cannot use internet with WiFi turned off or out of range. It's offline. In settings data is turned on. Airplane mode is not. Yet when I go to about phone/status/Mobile network state, it says disconnected whether WiFi is on or not. Straight Talk tech had me change APN settings which didn't help, then said it has to be the sim card. It's the same with the new sim card. Does anyone know what's causing this?

Anyone have issues roaming? I'm in Paris and can't connect to a local network at all. Won't even register. WiFi calling seems to work, but I can't get even an emergency call to connect unless on wifi

Did you add Roaming to your account before leaving to France? I would also make sure that:
1. Network mode is GSM/WCDMA/LTE Auto
2. If you search for Network Operators from your phone, does it find anything?
3. Ensure that Data Roaming is selected
Also, power off your device completely and wait for 5 min before switching on (NOT AIRPLANE MODE). These tips have worked for me in the past, not with this phone but with other GSM phones. Please let me know any resolution, I will be going to the EU very soon and I'm hoping to know the experience from another TMo user.
Hope it helps!
Good day y'all,
I have a problem with the mobile connection on my phone, which is a Samsung Galaxy S4 (i9505) with CM10.1.
The mobile connection only works for a couple of minutes when i reboot the phone. After that time, it says "Offline" or "No network connection". I can still do phone calls though, so the connection to the celltower is still established.
APN settings are correct.
Data enabled is ticked
Data roaming is ticked (I need this, because my provider is using the mobile network of another provider)
Turning aeroplane mode on/off will not solve it.
Re-enabling data/-roaming will not solve it.
Switching to 2G mode will not solve it.
Searching for network again will not solve again.
Only reboot solves it.
Any idea what is going here? It's quite annoying.
Thanks.
Just reflash your rom.
Doesnot help. I am flashing the ROM almost daily plus i erase all caches.
*bump*
Now i tried the following:
Using the SIM card of my wife (different provider) -> no problem
My SIM card in my wife's phone -> no problem
My SIM card in my phone -> only working for two minutes.
I tried to modify the spn-conf.xml file by adding
<spnOverride numeric=”23212? fake_home_on=”23201?/>
so that the network is not seen as roaming network.
Still not working.
Now i changed the MCC/MNC to 23201.
Also not working.
Any idea what else i can modify?
Here's the deal, I bought my Rezound in 2012 and flashed it to PagePlus Cellular using CDMA WS.
I've used it and it's been fine, running CM10 most of the time. I just bought a Evo 4G LTE and switched to that. So I RUU'd my Rezound, and it says a SIM card is required, etc.. but there are no signal bars.
I go into About Phone > Network >
and Operater name is "Unknown," signal strength is "0", service state is "out of service."
Now, the question is, is that normal? Does the phone need a sim card to connect to verizon towers?
I don't want to sell it while it's not working. I did call up Verizon and they said the ESN was clear for activation though.
So if I sell it and the new user puts in a SIM card, will it clear up all the signal issues? Or have I done the RUU incorrectly? [I did it a couple times because it didn't work the first time (the SD card method, then I did fastboot method)]
Thank you!
That is not normal behavior and you may need to do some more work before you sell it.
Make sure all related network settings are correct for Verizon instead of GSM under Settings > Mobile Network menu.
Try entering on the stock dialer *#*#4636#*#* to access the hidden testing menu as well for the phone radio and verify it is on CDMA. If that code doesn't work on the dialer try it via an app like "Hidden Menus" or even "Battery Monitor Widget" by 3C (click "Tests" icon > Phone information from main page of app.)
Background: I broke off of my Verizon contract six months in and used my phone as a WiFi-only device (VoIP and internet texting apps) for the longest time. While I typically hid my signal icon and ran the phone in Airplane mode with WiFi toggled back on, I would occasionally turn my radio on to resync time and date to the cellular network. With no SIM in it clearly was syncing off Verizon CDMA signal still; I simply wasn't fully activated on the network any longer.
I just made the StraightTalk AT&T SIM card plunge the past couple of weeks and did an NV edit in CDMA WS as well, all alright on GSM. I am on the stock global ICS ROM at the moment, one I know could sync time on CDMA before. However, I cannot get the phone to switch off of GSM even in the hidden testing menu, even without SIM in... Likely has to do with the NV edits I made, and perhaps that may be your case too.
You *could* repurpose the sale as a GSM enabled unit... If it was even set up and working well as such. But due to the current technical issues of getting GSM mobile data above 2G I'd suggest to get it fixed and working back on stock CDMA for the consumer's sake if you can. Again AFAIK It should pick up a CDMA signal even without active service or the Verizon LTE SIM in, did so for over a year lol.

in the mobile network, I have it set to "CDMA / LTE" but I tried "CDMA only" and "Global" but none worked.
*#*#4636#*#* didn't work in stock dialer, it just disappeared when I finished typing it.
then I downloaded Hidden Menu, found *#*#4636#*#* in the list, tapped it, and it did nothing. I did some other ones and they did do something. I found htc diag mode, the same one I used to program it originally. I clicked read, and the phone number and min were blank. so I went to the prl and tried flashing a verizon prl file, then rebooted, and still nothing.
I'm going to try to RUU again and hope that solves it.
Update
I RUU'ed again, but still no luck..
Can anyone confirm whether or not, say you got a Rezound out of the box never activated, would you need a SIM card to get the signal initiated? I'm thinking either that's the case and my phone just needs a sim card to jump start it, or my rezound is toast.
My venerable Samsung Galaxy S i9000 (rooted, Android 4.2.2 using CyanogenMod 10.1.2 ROM, on Virgin UK) has always served me very well when roaming abroad, and up to last year I had no problems with data connections. I'm just back from France, and could not get any data connection for the entire 2 weeks I was away (I bought a travel pass of course, and got confirmation of validity). This is totally unprecedented. I spent hours on the phone (calls and texts were OK) to Virgin, who variously said they needed to refresh my account settings at their end, then that there were known European network issues, and then that the problem was with the phone. I was told to turn on international roaming, but I don't have that option. The options at Settings>networks>mobile networks are:
Data enabled - ticked
Data roaming - ticked
National data roaming - ticked
Access point names
Use only 2G networks - unticked
Network operators
I don't have anything called international data roaming, and indeed have never seen this on any Android version I have ever had. I have seen images of other phones where `data roaming' is replaced by `international data roaming', and I'm sure there is no technical difference. Roaming is roaming surely?
I am very suspicious that there is actually nothing wrong with my phone, and that something odd is going on with Virgin. The reason is that last year I was running Android ICS using a different ROM, and mobile data kept turning off. This went on for over a week until Virgin found it was their fault and fixed it. At that time they never mentioned international roaming. I've done the usual searches and not turned up anything useful. There can't be anything wrong with the handset because data access turned straight back on when I got back to the UK. Can anyone shed any light?
Hmm. Calls and texts were working though, just not data? And it wasn't an APN setting? I'm assuming they had you check those. Did it show you were connected to data but there was no data transfer? In Settings > About Phone > Status - what would it say? Disconnected? You've used the phone on that other network before? It's possible that the other carrier's data frequencies aren't supported by the phone.

Yes they got me to check all settings and all were OK, except that according to Virgin there should be this `international data roaming' option which I don't have. The signal strength icon on the home screen showed a little R not a little H as normal. So I don't think there was any data connection. My key question though is whether there is any evidence at all that rooting affects roaming. I've been searching the web for over a week and found nothing about that. Frankly I don't believe it.
Hello,
I purchased a S9+ from Samsung for the ATT network. I just had my ATT account suspended due to a military move and had the phone unlocked. I just got TMobile service, the unlock worked fine, I still see the ATT stuff when it's booting and I know that's firmware related, but when I try to enable wifi calling, it let's me turn the slider to on, but as soon as I do, it closes the page and the calling option is still greyed out. Any suggestions, I am going to need this feature overseas.
I think wifi calling only works on the phone's network. If you change networks it stops working.
