Help -problems with 3G sim card -keeps losing signal and resetting.

Hello,
Sorry if this question has been answered elsewhere but I am a noob to this site. I have looked -promise!
Basically I have had an XDA Orbit on O2 UK which I have had for over a year with no problems. Recently I changed contracts but kept the same phone and O2 sent me a new 3G sim card.
Now when using the device for a long time (such as wi-fi, reading a book in Microsoft Reader, making a call) the phone will lose the phone signal and slow down. If left it will sometimes recover and get a signal again, or sometimes it keeps searching for a signal for a few minutes and then resets itself.
Sometimes when it is searching for a signal the top area of the phone gets warm.
I have tried a hard reset but this has not solved the problem. Is this to do with the 3G sim card? Should I try upgrading the ROM of the radio stack? Or would an entirely new ROM help?
The version details at startup are:
IPL 3.04.0001
SPL 3.04.0000
GSM 02.67.90
OS 3.4.0.0
Please help. Thank you.

Try to upgrade your Radio ROM. That can be a good solution.
Cheers

Thanks -I will try that tonight.

Ok I have updated the radio ROM and I still get the same problem. It will be fine for a bit but then the phone will lose signal, keep searching, and eventually reset itself.
Would using an entirely new ROM help or is the fact that this was not fixed by updating the radio ROM indicate that is this more of a hardware problem?
The details at startup now look like this:
IPL 3.04.0001
SPL 1.11.0000
GSM 03.21.90
OS 3.4.0.0
Thank you.

Yes... That looks like a hardware problem to me, since you upgrade your Radio ROM.
But for a last test you can flash a WM6.1 ROM and see if the problem is the same.
If it maintains then is surelly a hardware problem.
Cheers

I don't usually post on these forums but have been a reader for some time!
There are some things you need to know about 3G before you use this handset with this sim!
it's against your terms and conditions to use a none 3G handset with your sim 3 can and will cut your number off (ive seen it happen)
secondly 3 only have 3G netowrks they use orange's masts for when customers drop out of signal range to 2g. Hence your using orange masts which take it from me are rubbish! they have some of the worst reception in the country and ive only recently stopped selling mobile phones i doubt they changed much in 6 months!
to cut it short you need a 3G phone to go with your 3G sim im afraid this handset is not capable of 3G .

Hi thanks, for your comments.
I am not using a 3 sim card, it is an O2 3G sim card. I have tried today to reflash the O2 UK ROM image with the original settings to see if this helps but it still spends a long time without a signal and resets itself when it cannot get a signal for a while.
Is anyone else using a 3G sim card in this phone?
It worked well enough for me today to ring O2 and ask them if I could be "downgraded" to a 2G sim card. They said that they don't even do 2G sim cards anymore, but they said if I go to O2 store they may have a 2G pay as you go sim, and instead of activating it they could transfer my account details over to it. Anyone heard of that before?
When I went to the shop they said they didn't have any 2G sims and to reset the phone and try to get the settings sent to the phone from O2 online. Which I have done but surprise surprise no luck -not that I really believed the guy in the shop anyway but thought it was worth a try.
Any comments or suggestions?
Thanks.

Just to update, I have tried so many different things to get this fixed but it seems as though the 3G sim card is not the problem, as all fixed now by buying a replacement battery.
Now the phone works fine all of the time -it does not lose signal or anything. The old battery must have been faulty.
I do not know the exact fault but my guess is that when I turned the phone on at startup it was ok, but then as soon as I did anything it was drawing more current/amps from the battery it generated a fault which then made the phone lose signal and eventually reset.
I'm not sure on the science of it all exactly but it buying a new battery on ebay for £7 has certainly fixed the problem.
The Orbit/Artemis works fine with a 3G USIM -they are backwards compatible with a 2G SIM card and this obviously was not the problem.

Hi.
I have a similar problem... my o2 xda orbit for the last few days keeps hanging and reseting. It takes some time for me to be able to turn it on again.
even if i take out the battery and put it back in again...
Is this similar to what happened to you?

I think that I had the same problem but with a normal 2g sim. After an
intensive use over 1,5 years my Artemis p3300 had low signal and frquently resetting. I resolve all these problems changing the battery with a new one. It's important advise all Artemis owners that a lot of problems can be due to an old battery!

Yes that's basically exactly what happened to me. It would lose signal, keep searching then eventually reset. When I turned it back on it would still not have a signal and would take lots of times of turning it on and off before it would settle down again.
I bought a new battery from ebay for £4.95 (+£2.95 p&p) and now everything is working fine and has been for over a couple of weeks.
I had tried changing the ROM and still had the same problem. I would advise you to get a new battery and try that.

Hi, I am from CZ... - P3300 by Vodafone CZ
When I connect to wifi I sometimes lose the signal for phone.. One time I lose signal during the phoning and sometimes I lose signal when I use GPS...
Phone is 1,6 years old...
It is the same problem, isn't it?
It's a pity :-(
Can you give me an advice where I can buy the best battery? Should I buy a battery in CZ (home) or in abroad I can find cheaper and better??
(sorry about my english)

Yes that sounds like the same problem to me, I got a new battery from ebay because I thought it would probably be cheapest.
Try Vodafone first as they will be able to sell you a new battery and it may not be too expensive.

Artemis no service

Hello everybody now switched from Wizard to Artemis, missing qwerty ehh.
Snipped it one ebay, lucky me didn't read the listing carefully, device was sold damaged, gsm signal weak or no at all, unable to make a call at all times.
Antenna seems to be in a good shape, device unlocked.
Digged forum inside out, no solution found so far:
Tried different roms, radio roms.
Tried original o2 (since mine is xda o2 arte200)
Changed to new battery,
Even got gsm signal booster,
No luck so far, Hardware?.

tried all softs and radios on xda no luck:/

Did you saw if the Antena Pins are making good contact with the motherboard?

yes and I double checked it now, tried to call afterwards. Even when the signal indicator is full, I'm not able to make a call.

The same problem with m650
Hi,
Unfortunatelly, I have the same problem with my m650 ;(. Since 4 days, I got the GSM signal problem. Especially inside closed spaces (flat), even if the GSM signal seems to be full I can't make any call (telephone ends it). On the fresh air it's better.
I'm curious, if You had find any solution to this problem out. I'd be very greatful for Your help.
Best,
Dzeus.

No Service?!

Hi guys, i have a weird problem that i cannot fix. (i have been searching last 2 weeks, and i've decided to post a new thread.)
I am using new 3vo rom for my dash with T-Mobile service, suddenly my phone stoped making calls, receiving calls, texting and everything related with my service. I thought there could be a problem with antenna, i opened my phone, cleaned the antenna in case of oxidation. Didn't help...
I have 5 bars all the time on the screen. sometimes is disappears. I try to chose network manually. mostly it gives me errors, i cant even see names "t mobile, at&t" etc...
I reinstalled 3vo but didn't help. I installed the original rom from t-mobile's website. it didnt help either. I called t-mobile, they said there is no problem with your number and your IMEI number.
What should i do? Do i have a hardware problem? I have no warranty anymore. Should i buy a new one or take it to tmobile to get it fixed?
Thanks a lot for your help...

Maybe your sim card has gone currorpt, see if t-mobile or even one of your friends sim cards.
Gotta Love GSM.

i tried that too, with 2 different simcards, one was t mobile, the other was at&t... i m losing my hope

sorry didn't understand, it also didn't work with another sim card?
I had the same problem with my dash a couple of days ago. In my case was the antenna because the signal was turning off randomly. I cleaned it, but also noticed there was a weak contact between the antenna and the phone so I bended it a little bit to fix it. Now it's working fine. It will probably sound stupid but have you try it with another battery? (sorry for my bad english)

"I thought there could be a problem with antenna, i opened my phone, cleaned the antenna in case of oxidation. Didn't help..."
I have 2 original batteries, one is brand new... i cannot understand. i started looking a used one on ebay already.
thanks for the answer guys. you are the best.

last update... solution...
ok, , i have found people who had this problem on internet... they couldnt find a solution like antenna cleaning, flashing again and again, apps, unbricking... so the problem was hardware. i changed the board. i got a broken dash on ebay. i replaced the board. voila.

Major problems with dropping calls!

First off, let me say that having been a WinMob guy for the past 4 years, this phone has been a revelation in good design. I love it.
The ONLY thing that is impacting my experience with this handset is its CONSTANT habit of dropping calls! This usually happens completely at random, sometimes 1 minute into a call, sometimes 10 minutes into one - happens with both poor service and full bar service.
Could it have anything to do with HSDPA being active during voice calls?? Haven't had this issue with any other phones before and I certainly don't want to have to return it for a fix.
Any help with this would be very greatly appreciated!!

I've experience it a few times, put it down to poor T-Mobile coverage so far.

Happens every call with me, really can't figure out what I can do to fix it. Just hope it's not a hardware fault.

Has any one had any similar experiences with their handsets? Or alternatively, any ideas on how to fix the issue?
Thanks, just want to know so I can decide whether to take it back or not...

Guys, any help with this?

Well, I've never had this problem until today when I dropped a call twice. Had full bars. Hmmm. (T-mobile in case it's a network prob btw)

Have you had a look on the T-Mo Android forum ?
http://support.t-mobile.co.uk/discussions/index?page=forums&forum=80103656d92cf90123e15db75a006088
I've not looked there for sometime now.

I've been using it in Switzerland for a week, and have had no dropped calls whatsoever, so i'm assuming it's something to do with T Mobile UK

(Just for the benefit of any one else who will read this, I'm on O2.)
Hey guys, might have found a fix for this -
1. Turn phone off
2. Remove SIM + battery
3. Put battery back in without SIM, turn handset on and leave for 3 or so mins.
4. Turn off, + put SIM back in w/ battery as well
5. Change Network data setting to receive WCDMA only
Seems to have worked, but haven't tested extensively.
Btw, thanks for the t-mobile forums link, did help.

ive also had the same issue. had the same problem on my hero on 3 before I got my desire which is now on Orange and still the dame problem. also g1 on 3 had same problem. must be a problem on Android or with data and voice at same time.

I thinks it's more the phone since I'm AT&T with a Telus Desire.
This happens to me too with 2-4 bars. I thought it was my cheek hitting the End Call but it happens with BT too.
Maybe I've just been spoiled with Nokia and Motorola's reception...

It happened in Taiwan before. It's sim card's fault. We replaced our cards with new ones and problems are solved.

SIM card not detected - then detected again

My phone is constantly failing to detect the sim card, usually if I restart the phone or leave it for enough hours it will "find" it again.
Short of reflashing it I'm not sure if there's any way to determine if this is a software or hardware issue. The phone itself is a refurbished one (thanks to the phones insurance replacing it a few months ago), however it is now out of warranty. If it was a hardware fault, how much would it probably cost?
Thanks, Shaun.

The first thing I'd try is a different SIM card or a different SIM card insert (bit of plastic that the SIM sits in).
Has this always happened since you've had the phone?
or
Has it happened since you flashed the phone?
As for the price of repair I haven't a clue (i do all repairs myself), but my guess is in excess of £150
You may want to provide more information before other, more experienced people, come to your aid.

It's slowly gotten worse over the last few months (the first couple of times I just thought it was a once off bug or something, which is why it's very difficult for me to give you an exact when it happened).
The fact that its gotten worse in itself is leading me to guess its a hardware fault - I could have knocked or dropped it and not remember or something.
I don't have any other SIMs but I'll give flashing it to a different ROM or stock a shot first.

I feel as if that is your best best before you go throwing money at it.
Good luck!

Does the phone say no sim card (with icon) or do you lose service?

It has done both, the latter's slightly more common though. Probably more often than both it will momentarily drop out, then come up with a "Preparing SIM card..." message.
Still happening after flashing it with a different ROM. Looks like it's probably hardware :/

Might be coxicial cable that connects the pcb with antenea board they do come off from time to time

Hi there,
i have a similar problem with my device:
network disconnects sometimes (for some reasons ok, as example when i sit in the underground or other places without gsm network) - but then the services doesnt comes back - i'm complete offline. next behavior: i'm just talking with full gsm bandwidth, and for really no reason i get disconnected -> no network anymore, no service anymore.
can it be a hardware fault or should i try to flash the modem (when possible) ? I'm on the latest HTC firmware, device isnt rooted or flashed... it is as i got it from the market.
thanks for a hint what i can try

See above could be that, what network you on?

I'm on GSM (in Germany the O2 network)

maybe the network fault can be solved:
just have read in the vodafone forum in uk and found a hint from a user, who was taping the back side of the SIM card with 2 stripes of plastic.
Have tried this and report tomorrow here if it solves the issue

Tested with taped SIM card and i can say: it works like a charme
