can someone help me please - signal keeps dropping - Android Q&A, Help & Troubleshooting

got a htc desire x and a S2 both on tmobile UK and the signal keeps going on both of them randomly in full signal areas and disconnects from the networks and i get 'emergency calls only'
today the htc lost signal but the s2 didnt - it comes back within 10 seconds. then later the s2 did but the htc didnt this happens wether on 2G or 3G in all areas.

Vondafone Netherlands

I just switched from Tmobile to Vodafone and before, the mobile network was always H and now on Vodafone, it goes between 3G and H. Does anyone else who has Vodafone experiencing this? It seems weird that it would be switching between the two. Maybe Tmobile just had better HSPA coverage....?
I'm on vodafone NL too. Indeed it switches between the H and the 3G. I noticed though that it only switches to H if you are actually using the connection, otherwise it just stays on 3G. Try updating the weather for instance, you'll see it switching.
That's what I noticed as well, I just thought it was strange. Good to know though.
What do you think of their coverage? I just switched, so maybe that might have something to do with it, but last night I couldn't get any service in my bedroom but with Tmobile, I had a full signal...
I live in noord-holland, and coverage is pretty good. Wherever I am I get at least 3G. Vodafone hasnt been very reliable though. There were two crashes on their network a few weeks ago that crippled the data network but they fixed those errors within a couple of hours, so nothing to really worry about. No problems since.
Same here in the UK with T-Mobile.
When I first had the phone I'd almost never see 3G, just H or G. Now, I regularly get 3G but as soon as I start to use the data connection it usually switches to H.
I thought at first it was a result of me upgrading the radio, but I'm not so certain now. However, data speeds seem good so I'm not concerned.

[Q] Not able to connect to Internet

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?

[Q] Atrix 4G NO SIGNAL

I‘ve got an Atrix 4G a few days ago. but have a serious problem now.
i have bought the unlock code and the code was accepted.
after i insert an GSM card,the signal status bar shows a big forbidden sign just like "NO PARKING".it works like a MP4 right now,cannot make any calls.
i have changed for more than 5 GSM cards.but still no signal.
anyone who knows what should i do now? thanks!
Have you tried manually searching for an operator and logging into its network under mobile network settings? (you can switch back to automatic afterwards).
There could be a frequency mismatch, but on the one hand this bad by is quadband gsm and triband 3g, and on the other hand that woul dbe something you checked before you bought.. right?
Where do you live?
I have a similar problem. My reception goes on and off a lot and sometimes a reboot works, sometimes it doesn't. I have real bad reception at places where my old phone (an x10mini) had very good reception. The wierd thing is that when I have reception it's 4-5 bars, and then it drops to 0, I live in Sweden and have Tele2 as my carrier.
Qatar - Same issue
Hi all,
I'm having the same issue with my phone... no radio signal at all. My friend has an HTC android phone that has the same hardware antenna wise and band frequencies as the Atrix and his works fine... and my friend has an Atrix here unlocked and it works too...
Any thoughts?
I'm having the same problem... It worked yesterday when i unlocked... Since today, It can't find my carrier network... I hope it's not broken!!!
i had the same probleme weeks ago i reset all and i stay always in automatic research

I performed a Hard Reset... Still no lucky...
I searched for Networks. Then I tried that carrier's SIM, and it worked...
Wonder why mine isn't working on edge nor gsm as yesterday...
Just figured out that my phone is not working with edge, gsm... only with 3G...
The phone is Quadband... So... Wasn't it supposed to work with all frequencies??

constantly dropping signal internaltionaly vodafone

Hi.
I was wondering if anyone can help me out.
Im currently in Albania using Vodafone sim card. My signal sucks most of the time I have no signal its comes once in a while for couple minutes maybe and then leaves again.
When I put the sim card in my cousins S3 (which his s3 is from here) it works fine, full bars 3G
So its leading me to believe its my notes fault.
My APN settings are good because when the signal comes for that short time my phones data and voice work as they should

No 3G connection anymore Steps down from LTE to EDGE

I'm having serious issues with AT&T LTE in central Mississippi. The LTE network in my college down has been here for at least 8 months, but after ATT did some network upgrades last month, I can no longer access the HSPA network. If I make a call, it kicks me straight down to the EDGE network after a 30+ second delay. Same thing when I receive a call. As a result of the delay, I frequently miss calls and the phone never rings. The issue just started this month. Tried the new APN settings as suggested on other threads, and that just results in EDGE only access. I called AT&T and they forced me to do a full wipe and have them do a network reset. That didn't really fix the issue.
I am on ViperXL 2.0.0 with the latest radio (have tried the older radio too, no fix). Still on HBOOT 1.32 (I think, If not, it's 1.35) I've researched the issue to no avail as to another solution. If I could just use the HSPA network things would be fine, but when there is no LTE I drop to EDGE and the signal strength on the EDGE network here is 2 bars tops when there is 5 bars LTE, so I frequently have no signal when I used to have 5 bars. AT&T, as always in their valiant effort to cover their own butts, says there is no network issue.
Input and solutions welcomed! Thanks guys!
Just tried a sim swap with a friend. He has the s4 active and it makes the step from LTE to HSPA+ with no issues. However, his SIM in my phone still refuses to acknowledge the hspa network. Any suggestions guys? I'm running out of solutions. Problem exists on elegancia and viperxl ROMs.
This wouldn't be an issue except that I live in an area where there is literally at most one bar of edge once it drops the LTE.
UPDATE: After the new sim didn't work, I went ahead and relocked the bootloader and flashed the official RUU. No luck. It seems as though my HSPA radio has actually gone out and will not work.
Weird. I went back home and it works perfectly. But it didn't work where I currently live or anywhere along the 75 miles of travel. Regardless, the replacement HoX+ will be in next week.
