[Q] Orange/t-mobile network sharing in the UK

Hi All,
Done a quick search on this and can't find anything relevent, but i apologise if a thread already exists.
Really a question for those in the UK on the t-mobile network. Have any of you attempted to sign up for the orange 2g roaming service yet? I signed up, recieved the confirmation text, replied to it, and received the final confirmation. However, I'm not sure it's working. The signal seems no stronger, and i still drop in my house.
Obviously i'm posting this in the android section because i'm running android myself and am wondering whether anyone in the same boat has managed to get roaming to work. Should the fact that we're on a non-official OS running off the sd card make a difference?
Oh and for completeness, i'm running shubcraft 1.5 rmnet.
Cheers fellas!

I'm quite happily flip flopping between Orange while at work and T-Mobile for everything else...
works like a charm for me though you do have to stick the phone into Airplane mode after selecting the different provider for the data to work ...

Many thanks for the reply Jezwick. So, just for clarity, you're manually selecting each provider as and when required? Because i can do that, i think. When i select orange though, whilst it registers with the network fine, i get a little "R" above the signal bar (any ideas what that means?) And the speed appears to be limited to Edge. Orange have a very strong signal round here, so i figure i should be getting GPRS really.
It's the auto-switching i'm not totally sure is working really. Is there any explicit indicator that it's flipping on it's own? Or do you just observe a generally better 2g signal, rather than say, a very weak 3g one? Round the house, my phone is still trying to make do with 1 or zero bars of 3g. I would have hoped it would flip over to orange more or less all the time under those circumstances. Nothing to stop me manually selecting it i guess though...

The R is indeed for roaming that's the way it works if your not on your 'own' network.. The 'flipped' service will currently only work at GRPS speeds at the moment but should be 3G by the new year
I have noticed mine flipping automatically but only once or twice in the last few weeks but only when I get NO signal from the current service.

Understood - thanks for the info Just done some reading and apparently EDGE is faster than basic GPRS. For some reason, i'd always assumed the reverse. Looks like the best option is just to have it always on orange whilst at home and use wifi for data (which i do anyway to compensate for the poor signal). Cheers!

Help, cell signal acting weird after ROM

Hi, I just put in Darky's rom onto my Bell Samsung galaxy but my cell signal seems to be weaker and sometimes just loses signals. This hasnt happened before and I'm wondering what the problem is. The bars would go up to 3 then 2 then nothing and then back up to 3. Thank You.
Edit: It appears im on GPRS network and I believe I was on GSM network before so does that make a difference? I'm on Rogers network btw.
I also have speedmod k12h on it as well.
It seems im on the GSM 1900 and I guess I lost GSM 850? Anyone wanna help me?
Dont have data plan as well

Darky's rom
You have changed the firmware including the modem .
I would ask Darky for solution its his rom .
jje

Wow, this is ridiculous and why is this happening?

Please help:
I'm on CM9 19 6 nightly. Using Semaphore kernel without any modifications to the scripts.
The problem: My signal keeps on going out at regular intervals.
I've used XXJVU, DDJV5, XXJVT, KF1(Nexus modem for ICS) and various more. I stay on the modems for a week and then change to another one. The latest one is DDJV5 which I have been using since the past 2 weeks.
Tried all of the modems I could lay my hands on. Nothing works.
But the moment I come to work, the signal keeps fluctuating over the day. Sometimes it would be out for 10-15 minutes. When it's back, it would get back to giving -65 .. -71 dBm. It would stay like that for a few minutes and then it would be gone again for another 10-15 minutes or so.
It has turned into an OCD where I keep checking my signal.
This does not happen when I'm back home and then I'm back to getting good signal.
Yes, this looks to you like a locational issue. I thought so too. BUT, how did I get so good signal till a week back at work?
Question: What could have made this mess to my signal reception? How can I solve this?
No, all my syncs are OFF. I keep my 3G turned off and only use it once an hour or so for a few minutes. I don't use any signal consuming apps.
Also, sometimes the 3G would work even without the signal.
Another thing, sometimes there's a (x) sign at the signal bar thing and sometimes there is no (x) without bars.
As a cure for the OCD, I've taken an off from work today just to get some rest from checking my signal every now and then. And maybe find a solution.
I'm on Vodafone India.
Indians, I am on Vodafone India in Pune, Hinjewadi Information Technology park. Maybe Pune guys can help me out too?

maybe the phone changes the network mode.. 2g 3g or i dont know , try to put in in 2g only mode , or gsm only mode.

When the signal bar shows with a "x" it means the network is not available...go to settings and change the Network mode to "GSM Only". It will solve the fluctuating issue but network speed will be limited to 2G only.

Thanks, let me try it out.
Where is the network changing option to GSM only in ICS?
Okay, I guess it's the 2G mode.

Is going to 2G mode my ONLY option?
How can I fix this and get back to using 3G?

Update:
Changing to 2G mode fixed the problem. BUT...
I have a few questions now:
I want to use 3G but at the same time I don't want the signal to fluctuate between 2G and 3G—want to get constant 3G connectivity without signal fluctuations. Is there any way I can fix that?
I remember reading somewhere that going to recovery and changing permission helps this.
Anyone knows how to change the permissions so the signal fluctuations stop?
I have done a lot of reading on XDA but I haven't noticed an issue like this.
CM9 guys, anything please...

I have the same issue mate...using 2G is the only option to get signal without any problem.
The problem doesnot lies on your phone but the problem is with the operator. The area where you live hardly 3G signal reaches there (same problem with me).
You got two options to fix this issue:
1. Change your Network Operator
Or
2. Settle to another location where 3G signal is fully available

Both the options look impossible for me at the moment.
I will start living with the hope that the operator brings us some decent 3G signal here.
Thanks a lot anyways. It was helpful. Hope others facing the issue can learn from this thread. :good:

Complain to your provider, very loud!

:gooditto the same problem occured to me on Vodafone (Chennai) tried all modems listed above nothing worked ...Used to lose signals all the time with 2g data on especially at my workplace intermittently for 3-4 months ever since I upgraded to ICS..Sometimes used to lose signal even if data was off..multiple reboots/restarts gave no solution ..issue persisted across all the 15+ roms i might have flashed over the past 6 months..
Finally fed up I ported the number to AIrtel..everything works like a charm on JV9 I must say now..can vouch it's a network issue at the location

I am getting constant 5 bars on the 2G network. 3G gives me 2 bars at max.
Asked Vodafone about the future of 3G in my location and they said "We are spreading, sir. We will keep you informed".

I've had this problem too when the phone was constantly switching between 2G and 3G/3.5G. Try adding "Toggle 2G/3G" to notification drawer, set the "Network modes" for it to 2G/3G Only or 2G/3G Only/3G+2G. Switching between modes can take 10-20 seconds, but you should be able to test if you can get good enough 3G only connectivity (in case it is just a network switching problem like for me).

If you want 3G only, Dial *#*#4636#*#* - Phone information - WCDMA only.

Bad Reception with this phone?

Hi,
Was wondering if anyone got bad reception with their phone. I tried 3 different carriers since I had my ideos, in neither of them I ever had very reliable reception and lately the problem is getting worse. I'm running aurora 4.1a and I loose reception all the time, and the battery drains so quick because it's always looking and looking. My sister, my mum and my dad all have good reception (2 of them with my old carrier and 1 with my current carrier).. I can put my dad's phone (same carrier) next to mine.. he will have full bars with 3g and I'll have no reception at all!!!!!! Then it connects and disconnects again, and so it goes... Anyone having such issues?
Thanks.

I'm having the same problem, I'm running Aurora ICS. I use to always have good reception everywhere, Then suddenly I've just been unable to. Any help would be great! If I do find out any fixes to the issue myself I will sure let you know.

Good to know that I'm not the only one! Thanks. Hope we find a fix soon.

I've fixed mine now, What I've done is I've gone into Settings > Wireless & Network > Mobile Networks, and scrolled all the way to the bottom, and simply re-registered on the network and selected Use only 2G Data. Mines now working fine with full connection everywhere. However I don't know if our problems are exactly the same, however this is what fixed mine. Sorry if this doesn't help.

I have the same issue. Mine connects to 3G and has good connection, but then it simply disconnects and moves to 2G or reconnects to 3G some time later. That happens pretty frequently and I thought it was an issue with the carrier, but now I am not sure anymore.

Blefish, that is EXACTLY what happens to me, and I tried 3 major carriers in Australia (the only 3 that have their own actual towers). Just after I posted this thread, I happened to do the same thing as IwAsBlack recommended and... so far it seems to work. I have generally better connection and I haven't seen that ugly no reception icon since! Of course, internet browsing will be generally a bit slower but then again, it's better than staring at the phone for 3 minutes until it reconnects just to open Google.

You haven't stated which model you have. I got rid of a Motorola Bravo for at U8800-51 and I have excellent performance over AT&T (US). Crystal clear even with only one bar and I have never had a dropped call.

Have the same issue on any ROM with any mobile network in Belarus. Can't use 2G as recommended above 'cos of a huge use of mobile internet for some net-radio.
Sorry for bad Eng.

Its a U8800 Q&A forum, I didn't think that I had to state the version since I have a U8800.
Yesterday I tested and kept an eye on for the whole day! The reception since changing to 2G only has been AWESOME! Only had a drop out when I was in the subway (of course!) but aisde from that, I had amazing reception not to mention.. that my phone lasted the whole day with still 15% left!! (3G on, it would have to charge it twice while I'm at work) So, it fixed my reception AND my battery problems.

FYI, Ideos X5 U8800 describes four different models.

I know it does. What I meant is that I have the Normal U8800 model, so I didn't feel like it was necessary for me to point any variant model number like PRO or 51 or H, because it's STANDARD U8800

So we can make a conclusion that U8800 does not operate well on 3G. I can't switch it myself because I want to use internet too. And I am pretty sure we can't do anything about it, no matter if the problem is in hardware or software.

Mate, if you switch to 2G you will still be able to browse the internet! It will only be a LITTLE bit slower, better than having constant disconnection!!! I constantly use the internet to sync my gmail, send free texts, browse the net and a bunch of other stuff.. works even better on 2G with constant reception, not to mention the benefit of the phone battery lasting a whole day (AND still have internet).. so switch to 2G and you will like it... still good internet only with better reception

Same issue
Having same issue when using GSM/WCDMA auto or preferred modes. works normal on GSM network only.
Even when I have no signal of 3g, gsm is working in the background.
problem arises when I have a call, 3g signal drops to minmimun, after the call phone tries to reconnect with the 3g signal but drops the GSM signal in the process.
Try this , as soon as you disconnect the call, try to call yourself from other at that instant only. Your phone will be shown unreachable because phone drops the GSM signals.
