Wondering if you can help me.
In my office my colleuge and I have an hd2 on UK o2 pay monthly. Untill about a month a go we were getting HSPDA internet access. Now we are only getting EDGE. I contacted o2 and they stated that the area is a very high coverage area and we should be getting HSPDA.
What makes matters more interesting is two other colleuges in my department in the same building, one has an iphone 3 and the other has an iphone 4, both guys are on uk 02 pay monthly and are getting full 3g access. I am getting 3g and hspda in other areas.
Does anybody know why we are getting edge instead of at least 3g?
thanks.
I had a very simillar issue, so perhaps the solution I found will work for you. A co-worker of mine bought an HD2 (immediately after seeing mine). In many areas at work the reception was terrible. I also noticed that at home, when I first had the phone I got 3G often, but after a few weeks I was suddenly stuck on the EDGE network (If I got any reception at all). Since messing around with the Android port I was forced to flash a new Radio ROM and it seems that was my problem all along. At home I now get constant full bars HSPDA. At work I get reception in places that I never did before. My coworker (still using stock radio) is having the same reception issues I used to have.
So my advice is try a few different radios and see if that helps.

Yea we did try that the other night thinking it might be a radio issue we went from 2.5 up to 2.12. What rom / radio did you use if you dont mind me asking?
Does anybody else have any ideas? This is happening with two ok uk hd2's in the office! My colleuge and I have tried multiple rom and radio upgrades but nothing is working but my other colleuge on iphone can get 3g sitting beside me
ive had this issue too, never knew how to fix it :/
AGHHHHHHHHHHHH Going to call o2 tomorrow and tell them I want to swap for a new phone, I am not getting the service I should be!!!
Ive tried just about everything I can think of. Ive tried updating the ROM, Radio, rilphone.dll - also tried going back to stock rom, yet my colleuge sits on his iphone right beside me on 3g its madness!
have you tryed puting your phone into flight mode then .ack on again let thephone pick the strongest hsdpa mast signal up. welcome to tbd way o2 works lol we get it all the time in york and leeds
That is a very interesting idea. I will try and report back thanks man!
I am really getting no ware with this. Phoned O2 and they tested phone in my network said that I should be ok I should have full hspda access, my colleuge is sitting on iphone with ull 3g and has a o2 dongle which has hspda access. I am getting fulll signal strength, changed the sim card and tried multiple radio and dll file combos and this is driving me nuts. Any help would be appreciated.
I have been doing some further testing and found something interesting. When I am at home and can connect to HSPDA. I went into the base band and changed it to WMCDA got full access. I then changed it to GSM band and got Edge. I then went into work to test it and tried to force it to WMDCDA but it wouldn't even connect at all no coverage.
I tried it back on GSM and full coverage but only edge support. Any ideas?
I just got off the phone with a Verizon rep and they confirmed that there are no network outages in LA. So I guess there's something wrong with my phone. I'm currently running the debloated OTA rom with the radio that comes with it. I can intermittently connect to 4G, but only the upstream seems to work. It randomly cuts out, bumping my internet off or dropping me to 3G and 1X. Does anyone have any insight into this?

Well I think you were lied to,they have been messing with the network in several market over the last few days,if flashing different radios doesnt fix your problem it has to be the network, in sioux city iowa the same thing had been going on ask day, they are getting ready to switch the 4g on, it happened in three twin cities yesterday when they expanded the coverage, can't always believe what the reps tell you

The rep seemed like an honest dude, but I guess there could be sneaky network changes and upgrades. It might also be hardware damage. Does anyone about the 4G antennas on the back cover of the Thunderbolt? Does anyone know where I can get a replacement? A ticket has been opened for some techs to check out the network in my area. I'll keep you all updated.
You're sure your network mode is on CMDA / EvDo + LTE?
Positive. I can't think of anything else except network issues or hardware damage. :\
I am still in sioux city and the network is flippin out,give it a day befor you go buying hardware

Good call on that one. 4G is up and running when I leave the apartment. The strange thing is I have basically full 4G reception outside of the apartment, but inside: no 4G, but full 3G. Such is life, I guess.
I have an SGSII on Telstra running darkyrom XXLPQ with KH3 modem. I've got an issue where data works fine on H+, but whenever the phone drops back to 3G I get absolutely nothing. I've tried disabling fast dormancy etc, but that just seems to reduce how often it falls back. Is there a modem I can use or a tweak that will let it get data on 3G as well as h+?

I think you are better off on T-model modem, like DVKF2 by telstra as that will work on your I9100T model best.
I have the same problem on stock 2.3.4, xeu. But it just about never drops back to 3g in Melbourne. So haven't bothered with telstra modem yet.

I have a feeling you don't understand this very well and if I'm wrong I'm truly sorry. Either move to an area that you know does not have hspa coverage (otherwise known as 3g+ or 3.5g or h+ or 4G in North America depending on the phone model,manufacturer and provider) but rather only 3g and test there and come back to us or disable hspa in hidden settings (phone control/nas control/hspa control/choose r99 hspa off),which should disable hspa/hsdpa and hsupa and test and come back to us. That should give you data while 3g symbol is lit at reduced speed of course.
Right now all you seem to notice that when you engage data it is h+ and when it falls back to 3g, the symbol is only for voice over 3g therefore no data arrows.
Yeah, I'm talking about when I'm I'm an area that has poor hspa coverage and it drops back to 3g. Btw, my old xperia had no problem getting hspa in these same areas, so my radio performance is generally pretty bad with the sgs2.
Try all the I9100T modems until you find one that works well for you; they do generally work better with the I9100T than I9100 modems. And if that doesn't work, then you might as well try all the I9100 modems.
I've got an I9100T & found there's 2 or 3 I9100T specific modems that I get great signal strength/data speeds with (and granted 1 I9100 modem), and the rest are ordinary for me.
There is no simple fix for this. It's a trial and error thing. Unless you want to spend hours on the phone to your telco for probably zero result ?

Threw me off, because of mentioning 'fast dormancy'.
Good that I apologized in advance then.
I would still recommend testing it the second way I suggested just to see whether it works at all. I also sometime end up in an area that while seeming to have full strong signal, due to a congestion at a peak and other factors, has no or very little data throughoutput (this being in canada).
As suggested by others, testing other modems may help as well.
Don't even get me started with sgs2 and nokia's regarding radio.
Hi All,
I am having a strange problem with my S2 since last few months. I am from Mumbai, India and using Airtel network. There is a spot in my apartment which has very poor network reception of Airtel and I face issues whenever my cell is in that spot for a while. It happens that whenever I take my cell in that area, it starts losing signal bars till no bars are highlighted on the status bar at the top. It keeps showing zero bars but does not show "no signal" icon. Then, after keeping my cell in that spot for a while when I bring it in a better connectivity spot, signal bars start increasing and it appears that my cell has better reception again. However, if anyone tries to call me or I try to call anyone, they get "Out of coverage area" message or I get "Network registration failed" message respectively. I am having this problem since the day I started using Airtel and have tried a lot of remedies but only thing that works is rebooting my cell. I have tried using OpenSignal app to reset my connection whenever my cell comes back from the spot but even that fails to revive it and ultimately I have to reboot.
Has anyone faced such an issue and any ideas about a fix? Does it look like an issue with my cell or could it be an issue with my network provider? I would prefer not to root my S2 since I have 3 years warranty on it but if you think that it's the only way out of this, please let me know your opinion.
Thanks.
Sounds like a carrier issue to me. You pretty much said exactly that yourself when you said 'There is a spot in my apartment which has very poor network reception of Airtel and I face issues whenever my cell is in that spot for a while'.
That's normal in many buildings. Particularly if the network coverage in your area is borderline or poor. I have a similar issue in my house, in a few rooms I get no bars & sometimes coverage drops out completely, whereas in my loungeroom/dining/kitchen at the back of the house I get good coverage (for me, anyways).
You could try different modems, which might improve things. You don't have to be rooted to flash these, you can flash them using Odin. Tho it is easier to flash them with CWM if you're rooted.
I use to had the same issue with my 3 carrier at my desk in the office, and still on 2g services. I but since last month they already improved to hsdpa network added more bts and now my blank spot became H.
Yes you may try to change other service providers

Thanks for your suggestions guys. Yes, it might be only related to the carrier. But, I think that if signal goes down to zero and then when my cell is back in better coverage zone, shouldn't the modem take care of network registration by itself? My problem is that it doesn't. I have to reboot my cell every time after I come to know that my cell is showing signal bars but is not actually registered on the network. If I reboot my cell, everything becomes normal and so if it was just an issue with the carrier, shouldn't it continue like that even after reboot? If I think about it logically, I think following should help me out:
1. Try out a different cell for a few days and see if I face this issue or not.
2. If answer to 1 is no, then try out different modems on my S2 and see if that helps.
Actually, I just wanted to check if anyone else has faced this issue and figured out that something is not right with S2 drivers or something? That would help me with quick resolution of my problem.

Yep, your logic is sound ;-)
One thing tho. With regard to trying your sim out in another phone, you have to keep in mind the radio hardware is obviously different in different phones. And what that means is (and this is something I've observed on XDA), chances are you'll find the sim works perfectly in the other phone & you have no issues at all. This might be due to the actual equipment your carrier is using in the cell tower(s) you're close to, also the frequencies that gear is using might also be playing a part in your problems.
So definitely try it out in another phone & see what happens, but you could do worse than try out a bunch of modems in the S2 & see if that improves things.

Those are carrier issues, and maybe even the material of the constructions, in my house there are rooms where there's almost no signal at all, and in the living room it's ok, you should try to see in which tower you are connected maybe thats the problem
I have also had these problems on various networks here in Australia. If you don't need the data network, you could try using 2G only option. But that's not really a fix, is it? I suggest you try a pre-paid SIM from another network provider, to test them out first, before re-contracting.
Good luck. :fingers-crossed:

Yes, I was also thinking about it. It could be the combo of cell tower and S2 that are not liking each other that well.. And, if that's the case, I really hope that the issue can be resolved by switching modem drivers. I will have to do some what-ifings to nail this down now.
I like the other suggestion by HotrodHarry on trying out 2G only option - not the best way out but will help me in zeroing down on the cause.
So almost after 3 weeks of getting the TS I decided to put in my AT&T SIM. I was reluctant to use that tiny bastard screw driver but I did it anyways. I have noticed that the network signal strength of my watch is almost non-existant. It will get cellphone signal at only certain place. With the same sim card on my phone (Nexus 5), I get good cell reception.
How are others doing in this department? How's the cellphone signal? Is there anything I can do to improve the mobile network signal. Currently I am on stock with Loki's security patch.
I am not sure if this is a hardware issue or software issue. I remember someone opening the TS and checking the antenna. Any suggestions would be highly appreciated.
Some information on my TS -
North American 1/8
Stock ROM with Loki's patch.
Ok here is my observation:
I could not get signal inside my office, home and costco
I did get signal once I get out of my office - full signal bars with H+. I made a short trip from office to costco and home and back to office. It was able to get signals when I was driving but in some areas where I used to get 2-3 bars in my phone, TS did not pick at any signal at all. So mobile network signal is working but it is pretty weak compared to my phone.
May be it needs some tune up
i have the same problem,the signal is low and TS really has a hard time to find one,if its lost
can we do something about this ?
I opened mine just to have a look and found one of the connectors lose, took a bit of fiddling to get it back on but my network signal seems as good as my note3.
I don't know why, but after installing this app.https://play.google.com/store/apps/details?id=com.misonicon.signalbooster3g4g
The signal works perfectly, I didn't believe in this apps but now I don't know what to say
At least it works
Mobile frequency fluctuates on my end too, made sure APN settings are listed exactly like they say here on the forums, maybe I should change to another GSM 3G SIM card?
