Not sure if this is the correct forum but I want to be able to turn of roaming completely. I have a US G1 on the three UK network with the US RC33 installed and root. I have disabled data roaming. Here in the UK we're too small a country to want to roam! Coverage is usually good enough from a single network. However, I occasionally get the little 'R' symbol on the single strength icon and an annoying prompt saying I need to turn data roaming on because I lost connectivity. I have to go into the settings and manually select the "3" network again.
What I want is to either be connected to three UK or not connected to anything at all. Is there a config file I can edit to allow this? Would the UK RC8 firmware do this for me?
Thanks in advance for any help.
Doesn't a 3-UK SIM try to roam onto O2 though?
You could set the phone WCDMA only and NOT roam onto a GSM network.
Use AnyCut to shorcut Activity: Phone Info
From there under preferred Network Type; set to "WCDMA Only"
HELP!! Roaming signal won't go away
I have an unlocked G1, JF1.41 v 1.1 and i just updated to the RC33...but this also happened when i had RC30 , v 1.0...
I put in my canadian Fido sim card and everything works fine but i have that little "R" on top of my signal strength bar...
I think this means its data roaming? if this is the case...it should be okay (even though its going to bother me) because my service provider says my EDGE/Data is disabled (i do not have a data plan, NOR do i wish to incur any data charges.. i'm fine with my free WIFI ) .
However, if this means im roaming on another network, i dont want to be incuring any long distance charges on my phone EVEN when im using my own FIDO network..
I went to settings - about phone - status, and here are my specs (some of them):
Network: Fido
Network Type: EDGE
Service state: In service
Roaming: Roaming
Data Access: Disconnected
i'm pretty much just concerned about the ROAMING part of it... my other friends with G1's are with rogers, don't have that little R..
how do i get rid of that?? please and thanks!
Try manually changing the network in Settings>Wireless controls>Mobile networks>Operator selection
G1, like all GSM phones, will roam onto networks specified on the SIM if it can get a better signal. As long as the relevant operator has a roaming agreement in place, there's nothing to be concerned about, other than the R symbol in the status bar.
Mod: move this over to General discussion please.
I did change it and selected my Fido network (it's the only network available).
Thanks. I've set it to WCDMA only so I'll see how it goes.
Please help??? i still have that little R on top!
After I got home I found my phone had lost its connection. It didn't seem to be searching for the network. I had to go into settings, search for networks and then select three again. Is there any way to control if the phone does a search for networks automatically?
Looks like it reconnects to three on its own after a while. I still get the annoying popup about turning on data roaming though

As has been previously mentioned, Three will "roam" onto another network if it goes out of Three's own 3G network coverage because Three does not run its own 2G network.
However, it isn't O2 anymore, it is Orange as of late 2006/2007. I *believe* that you won't be charged any more if you use data whilst "roaming" on Orange, so whilst you are in the UK it is quite safe to allow data roaming, but I would be inclined to check this with Three.

Hi Everyone,
I'm usually just a reader on XDA, but I have found a problem that appears not to have been solved and wondered if anyone had any insight.
Problem Summary
When in an area (or network) with only HSPA and UMTS (strong HSPA/UMTS signal, but with no LTE or 2G available), the phone will drop from H+ to 3G erratically, always dropping the data connection. Traditional phone calls are not affected.
Detailed Description
I have a OnePlus Two and have 2 SIM cards. My first SIM Card is with Bell Canada (Virgin), and the second SIM Card is with WIND Mobile Canada.
Neither Bell nor WIND operate a 2G network, so the lowest the service can fall to is UMTS/3G.
Initially, I didn't notice the problem because Bell also operates an LTE network, and there is no problem with dropping the data connections when on LTE.
When I switched to the WIND SIM card (which only operates HSPA and UMTS), I noticed a problem where the phone would initially connect to H+, begin downloading whatever is needed (say, streaming music), but then part way through the download, the connection would switch to 3G, and the data would effectively stop. Within a minute, the service would jump back to H+ and download some more, but this cycle would continue (H+ --> 3G --> H+ --> 3G... ), with no way of knowing 1) how long the H+ connection would last before dropping to 3G (usually less than 30 seconds), and 2) after dropping to 3G, how long before going back to H+. This problem makes the phone almost useless when there is no LTE.
The most obvious troubleshooting I did was move to locations of better signal but I quickly ruled that out, as nothing seems to remove this problem. Other things I tried was to: move locations in the city, reboot phone, hard reset phone, flash most updated version of Oxygen, unlock bootloader, root, try the HSPA Keepalive app, swap SIM1 to SIM2, and many other things.
I originally thought this was a network issue, but I put this WIND SIM in another phone and there was no problem in any way that resembled this problem.
I also ruled out this being a network-specific problem, as I have taken a trip with the Bell SIM to an area where Bell does not have any LTE coverage (only HSPA and UMTS) and the same problem occurs on Bell as with the WIND SIM.
I have found people who had this problem on the OnePlus One tend to recommend using 2G to stabilize the connection, but this is not possible on Bell or WIND. That solution also would not provide adequate data speeds.
Remember this problem only affects data connectivity, as 3G traditional phone calls have no problems.
Question
Does anyone know if there is a way to adjust the conditions when the OnePlus Two will choose to switch from H+ to 3G?
Does anyone have any easier suggestions?
Thank you all in advance, because this rendering this phone almost useless when there is no LTE coverage.
I believe your problem is that phone it's dualsim standby, that means only one modem that alternates signal for both sims, I think normal would be alternating from faster network to slower network on sim without data.
Having to change to g3 between sims theres something stoped in the modem and data connection is also stopped.
You have no problem with voice calls because other sim is automatically turned off and unreachable.
There's nothing you can do if you're forced to only 3g on both sims
By 3g I mean 3g or h+ which to my knowledge are the same
Hope I was helpful and not wrong or more confusing

Thanks, I will try disabling the second SIM to see if there is a bug with the dual-sim...
What it currently does with the second SIM is it either shows "R" for roaming or just emergency only, but perhaps there is a software issue so I'll see if disabling the second SIM makes a difference.

Though strange, this workaround fixes the issue. Thank you to fburgos for the suggestion!
So just in case anyone ever finds this issue creeps up on them, the solution is to DISABLE the SIM you are not using. It's not the most convenient workaround to swap SIMs, but the other SIM will be in Emergency Mode, so it really makes no functional difference.
On the technical side, it does appear that there is actually a bug in Android for a very uncommon network configuration. It will only appear in this exact configuration:
SIM1: Network has HSPA/3G only, no LTE or 2G to move to
SIM2: Network also only has HSPA/3G with no LTE or 2G
The non-data SIM does NOT connect to a roaming network (connects with "Emergency Only") - if it connects to a roaming 2G network, this problem does not happen.
The data SIM connects to HSPA/3G
Both SIMs are active
I'm not sure if this will happen anywhere else in the world other than having a WIND Mobile Canada SIM and Bell or TELUS Canada SIM
If anyone has insight on how to report this to Google, or someone else who can confirm my theory, that would be great!
Try this:
1. You need to make sure you have the correct LTE APN selected in mobile networks and LTE as preferred type.
2. Go to dialer and type in this: *#*#4636#*#*
3. Phone Information
4. Set Preferred Network Type to: LTE/GSM (PRL) - you an play with which one you wanna use but the one I said works for sure. on other roms I have" TD-SCDMA, GSM/WCDMA and LTE"
5. Now click TURN OFF RADIO and wait WAIT few secs. will that button turns to Turn Radio ON
6. Now TURN ON RADIO and wait
7. when u see the triangle for the signal is back, at least black , go down and lick SMSC REFRESH then UPDATE.
8. now just go back to APN settings and go into your LTE APN
9. Change Bearer to LTE

I have the same problem. Do you already have solved it?
I use only one SIM card so it is not a problem two cards.
really you do not have this problem? if no one knows the solution?
compared with my htc butterfly 2 and another low-end android, one plus 2 running latest Oxygen OS has serious connectivity issues. I compared the signals strength using same sim card in same location (including being connected to the same tower) and One Plus 2 keeps dropping the connection and has really poor signal strength. I have tried the *#*#4636#*#* and tried different network modes, but none of them are helping. Its a real disappointment that the basic feature of this phone is screwed up.
I have tried with CM13 as well. Any ideas if this is a modem version issue?

Did It.. But it seems like it didn't solve my problem..
Just posting this in case somebody has some ideas. I've had a MetroPCS LG Leon LTE (MS345) for over a year without problems, but now it started losing its mobile connection sporadically, for a few minutes or a few hours, as if there was no SIM in the phone.
Symptoms:
The 4G indicator disappears from the notification bar (signal strength indicator shows good signal).
The lock screen says "Searchng..."
Calls fail with the "Emergency Calls Only" message
SMS won't send
I get a "Service Unavailable" error when I choose Settings/Call/Additional Settings
WiFi is unaffected (and WiFi calling seems to work, though it has always been hit or miss)
Things I've already tried:
Checked relevant settings, APNs, etc
Checked the contacts on the SIM socket, all looks good.
Reset Phone to factory defaults
Replaced SIM (MetroPCS did this for free)
New phones are relatively cheap, but I don't have a burning desire to upgrade, so I'm hoping for another option.
I'm having this same problem. I left for an area with no service and came back to an area with service to find that my phone will constantly state Emergency Calls Only and no service. Does anyone have any suggestions?
Hi all.
I’m experiencing a problem with my dataconnection which renders my data connection almost unusable.
Hope someone can point me in the right direction!
The situation, I am using a Oneplus 6T with 2 sim-cards. One for calls one for data. The sim I use for data loses the connection multiple times while commuting to work (train).
It happens on the same locations so I assume it has to do with switching between towers. The connections completly drops to no signal (the other card still has a signal).
After the connection drop one of the following happens:
- Reconnect to 4G after a few secons to minute(s)
- Reconnects to H+ and stays connected to H+ until I switch aiplane mode on and off). Even when getting of the train and waiting on the same spot it hangs on H+ until I use airplane mode.
What did I already try.
- New SIM card from provider (Tele2)
- Complete profile reset by provider and check of APN settings
- Tried both SIM slots
- Tried the SIM card in another telephone (connection does not completely drop)
- Use another provider (T-Mobile) with this phone. The data connections seems to work fine on T-Mobile.
So it looks like a combination between Tele2 and the Oneplus.
(By the way Tele2 falls back to h+ and 3g from T-mobile if they can't provide 4G)
Thanks for reading and all tips and tricks.
I bought a brand new factory unlocked Galaxy S10+. I popped in my Tmobile sim card but my calls goes to voice mail and I can't make any calls in following conditions.
I also tried Verizon sim and it acts the same way so not sure if network is the culprit.
1) When the wifi is on, my phone identifies network as I see 'Tmobile' in screen, signal strength is '-113 dBm 0 asu' but no actual incoming/outgoing call.
2) When the wifi is off, but screen is locked for 3-4 min, I still see 'T-mobile' but no incoming/outgoing call. Also, the service state changes 'In service' to 'Out of service' intermittently where I have to toggle aeroplane mode.
So, I have to toggle aeroplane mode on/off to get the network back while wifi is off, signal strength is '-81 dBm 59 asu' then everything works normally until I lock the screen as in step 2 or use wifi as in step 1.
This is my second replacement phone and it is behaving the same way as the first one. So, I am not sure if I am having bad luck with Samsung phones or if something is funky with my network. I also have a S9+ which has no issues at all with same sim cards and network coverage is excellent in my area.
Any idea or suggestion would be really helpful. Not sure if I should just change the firmware from U1 to Tmobile or something.
I would check your APN settings to verify that they are correct. I am on T-Mobile network with U1 firmware and have no issues with calls (I'm on MintSim which uses the T-Mobile network) but when I popped in my SIM no T-Mobile APN settings autopopulated--I had to enter the APN settings manually.
You should also make sure Volte is enabled in the network settings and WiFi Calling is enabled in the dialer settings.

Thank you for your response. My T-mobile APN settings auto populated and looks fine as I have LTE connection. The issue is that the connections keeps dropping and all my calls goes to voicemail in above two scenarios.
If the LTE didn't work at all or if my calls went to voicemail all the time, I would understand that some settings are not setup properly. But it works intermittently. Since, this is the second Galaxy S10+ with same exact issue, I am not sure if there is a issue with device or carrier.
