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.

Mobile Network Drop

Not sure if anyone else has had this problem but i randomly get mobile network drops once or twice a week. The phone works perfectly well but the mobile network just drops, you cannot scan for network at all. The only way i have found around it is to enable plane mode to drop all connections and then turn plane mode back off so the network starts up. This often takes between 5 - 10 mins for it to kick in.
Tried two roms but now back to stock but still happening.

Have you tried flashing the latest radio? They are listed in the dev section.

The recent OTA 1.21.405.2 update included a new radio I think. Did you put this on too?
Since then, I have also been having the network drop out. I am missing a lot of calls as a result. Prior to this update I had two months of problem-free operation on my stock 2.1 ROM.
From reading the google forums, this is a wide-spread issue. The light at the end of the tunnel seems to be that people updating to 2.2 froyo seem to see the problem stop. Two weeks to wait for us stock ROM boys according to the rumours then! Fingers crossed.
It's a bit embarrassing having this flashy toy when it struggles to be a phone at random intervals. At the weekend one of my less techy friends was waving his Nokia 6210i in my face saying, "At least I can make and recieve calls!". So I changed the language on his phone to Turkish when he left it lying about. The old ones are the best.
I am going to test the 1.21.405.2 theory by doing a factory reset later this week when I have time. Problem should persist if it is the new radio. Will post back with the results.

OK did a factory reset this morning. I left all my apps off, and did not set back up any google account business. I basically left it as a standard mobile phone.
Within 7 hours, guess what....yes it's lost the connection again. Strongly believe this is a radio problem. I'm too noob to know if I can flash the radio without rooting. Anyone?
I have since submitted my complaint with HTC CS. Will await their response, and post it here.
In the interim, turning airplane mode off and on again does regain the connection, and I have installed an app from the market place called "No Coverage Alert". It will now beep and buzz if I loose the connection so at least I will be aware every time it bombs out. Far from ideal but should do for now.
Watch this space.

Yes i have tried the two radios posted but i havent tried any international ones such as europe or asia. I still randomly get network drop and i need to turn radio off and back on again for it to pick up.
Maybe i should ask a chef if these drops are logged anywhere on the device so i can root in and look at the logs myself and diagnose what the network drop is on my phone.
Just to confirm, tried multiple radios and roms, i know exactly what i am doing all i would like is explaination of why it happens. It is not user error as i have tried with stock rom, no fancy apps etc to stop it from working or changing config.
its got something to do with the network radio libs that need a service restart. i am 100% sure if i rooted in and knew which service to restart it would work also

Erm.... this is a little embarrassing but I feel I need to own up to prevent misleading anyone. I have arranged with HTC customer support to send my Desire back for repair. They pick it up Monday.
I bought a cheap £10 phone to keep me going. It arrived this morning. After I had finished laughing at it, I put the SIM card in and powered up the phone.
"No SIM card instered" was the message it greeted me with. After numerous power-up and power downs, and some SIM card hoakee-coakee, it finally recognised the SIM card......then dropped the signal to Orange. EXACTLY what my HTC Desire did.
Doh.
I had tried the SIM card in another phone (my girlfriends Blackberry) when the problems first started and it had worked straight away. But the SIM card seems to be random in it's failures. Should have tested more rigorously.
Sorry guys but in my instance it seems I have simply a faulty SIM card. The first one I have ever had go wrong in 12 years, but there you go. I was too fast to blame Android/HTC.
A|ex, please try your SIM card in another handset. Do several power-ups to see if it goes wrong. Would explain why trying numerous radios/ROMs has not helped you.
Let me know?

I had the same issue. Talked all day and evening, then toyed around with the phone a little, flashed a new ROM, no connection. oO okay, that's weird. Tried 3 different ROMs, reset to factory settings. Went to Orange, the SIM was borked. Thankfully, getting a new one took all of 5 minutes and didn't cost me a dime.

Yep. Was the SIM card. The new one arrived from Orange this morning. Popped it in and it's working straight away. My 3G has even improved slightly I reckon.
Six hours of use and not one drop yet.
Thank god for that.

No more signal?

Hey guys,
I'm with Vodafone UK (notorious for their bad signal coverage) but this morning when I woke up, my HOX has had absolutely no signal.
I've tried everything I can think of to resolve the issues, standard restart, hard restart, removing the sim card etc. but to no avail.
I also wondered if it was maybe Vodafone having a bad day too and asked my friends who are also with them, if they had any signal. They all have full signal.
Then i checked the settings on my device, phone identity.
For some reason, the IMEI, IMEI SV, IMSI and phone number are now all unknown. I'm not really sure what this means, but I know they normally have something underneath them.
This has led me to believe its an issue with my sim card/contract whatever... maybe I haven't paid my contract so Vodafone cut me off, went online and checked. Everything has been paid for.
Got any suggestions as to whats wrong and how I can resolve this please?

Hi,
I had a similar problem (also on Vodafone, but it may just be coincidental). I had no signal for a couple of days and thought it was due to a screw up during my number porting from O2.
Anyway, after 2 days of calling customer services and having my SIM swapped twice I went into the store and they replaced my phone. It's fine now.

Funny enough I also woke up to phone having zero signal, but am with o2. After 1min or even less signal came back.

just got off the phone to the Vodafone people.
After trying my sim card in my friends Vodafone HOX (black), I got signal. This has led me to believe its a hardware issue, but despite this the phonerep still insisted it might be a software issue (I have the latest OTA update, same as my friend and his is fine? NB: his device doesnt have the flicker issue unlike mine).
Will have to visit the local store to have the shop monkey tell me the dreaded, "we'll have to send it away for repair" probably. If this is the case, the phonerep said I would probably have to pay for any repairs/new handset as I dont have insurance. Is that fair because I'm still well within warranty..?

Sounds about right, if you within your 28 days you can ask for a replacement. As per rules. Even HTC say to replace. Anything after 28 days needs to be sent to HTC for repair. You shouldn't have to pay for any repairs it should be covered under warranty. They can refuse or charge if you have tampered with it, as in did the HTC unlock and installed a custom rom.
See what the shop says, if HTC do charge then kick up a big fuss.
No issues with my vodafone sim in mine, however had terrible issues with GG, kept losing sim card I assumed it was a faulty sim card causing the issues.

Hey there, my girlfriend is on Vodafone with an iPhone 4S, she lost her signal yesterday morning and still hasn't had it back bar a five minute window this afternoon. she lives near a place called Devizes (its in Wiltshire) but her mum had it back from last night, I don't know anyone else on Vodafone so I don't know how far it has spread.
Edited to add: you can check for reported signal/mast issues here (http://forum.vodafone.co.uk/t5/Faults-Board/bd-p/69) the bit on the right of the first set of numbers in the thread title is the start of the postcode for the area the mast is based.

Think I'm a few days past the 28 days, just my luck! And I haven't done anything to the phone whatsoever, everything is stock.
More evidence that something's gone wrong... After leaving it on charge all night (as per), the battery has dropped from 100% to 14% in the space of 4 hours with just some casual wifi usage. It's also extremely quick to heat up now, and thats just from leaving it on charge.
If they make me pay for a blatant hardware issue I will kick up a massive fuss. Why should I pay to have the manufacturer fix a phone that has clearly been made to an unsatisfactory level?

No Sw. Dead radio - any way to diagnose?

My 2 month old One X seems to have developed a problem today, with it's GSM/UMTS radio. Was working fine this morning in Dublin. Caught a ferr y back to the UK and it was still fine but by the time I got to my office in Chester, it was showing no service. I just put it down to a local issue with the Vodafone network. But, on the 200 hundred mile drive back to London, despite rebooting and trying to force it to re-register as GSM, WCDMA in GSM/WCDMA modes, I've still not managed to get anything other than No Signal. Clearly not a general Vodafone network problem as the UK news and internet sites would be all over it.
I got back home and tried the other Vodafone SIM that I use in my Galaxy Tab (screwing up the SIM slot in the Tab, in the process) but exactly the same problem. I've spoken to Vodafone and despite me trying the other SIM, they've just said it looks like your SIM isn't registering with the network, so we'll send another out. All good except I'm off on holiday tomorrow.
I'm wondering if the radio "chip" itself has gone AWOL and wondered if there is any way to diagnose that on the handset itself? Any ideas if that's possible or anything else I can try to diagnose the issue?
Failing that, I guess it needs to go back to HTC for repair/replacement. Anybody know how warranty repairs work and how long it's likely to take to resolve and anything I should do with the phone beforehand?

You need to try your sim in another phone to eliminate the sim card
If its the same in another phone its the sim if it works fine its the phone

[Help] IMEI Issue ( I think)

So I've had my G3 for close to a year now, and just recently my phone's mobile network just stopped working. I thought it was because there was ****ty reception at my house, but the only places it doesn't have good reception was in my room. Anyways, I've had my phone up to now working flawlessly, but until a couple of days ago, like I said, mobile network wasn't working. I checked the apn, didn't have it so I added it even though it was working before. Reboot, and nothing. I tried reseating the sim card, no go. So from some info I gathered online, it was a good idea to check it's imei code. It's been reported lost/stolen and can't be activated, SUPPOSEDLY, even though I was using it fine until a couple of days ago. I thought it was because I hadn't recharged my sim (had a like 2 months without recharging it, and by recharging it I mean buy minutes.) Anyways, I had bought my phone in my home country, Dominican Republic, from an online website like craiglist so to speak. If the imei is reported stolen and can't be activated, is there nothing I can do? It used to be working a few weeks ago and I don't think I can possibly just lock me out like that. Any help would be greatly appreciated. Thanks!

if it's reported lost or stolen then the only option you have is to switch to another company. If it's not that then check your apn settings. If that doesn't work then try and get another Sim card. Sometimes they mess up and make your phone act weird
