erratic behaviour GSM reception

Guys,
Bought an australian O2 MINI from a friend of mine. BAck in Holland, one moment I do have a GSM signal....the other moment I don't.
My other phone, with the dutch VODAFONE has a 80% reception.
It's very hard to regain the QTEK GSM signal. Sometimes turning on and off the flightmode works, sometimes not. Even putting the newest QTEK S100 ROM doesn't.
When I do have a signal I ,fast as hack, mark the VODAFONE provider thingy and unmark all the asian pacific providers. I even permanently store my settings. A few minutes later, the reception is gone, Just when lying on my desk or driving in Amsterdam, the Vodafone Preferred network is gone and even the unmarked networks are marked again..but NO vodafone signal.
Is it beacause of a hardware problem ? Or when it looses the Dutch Vodafone signal, it only looks for the Pre-defined networks or what....
When I do know how to work with SMD...is it possible for me to repair ?
Hope someone can help

Problem with the quality of UMTS reception (signal weakness)

Hi all,
I have got mine since last Friday and I am wiondering if you get the same problem as I do...
The UMTS reception is very hasardous once you are inside a house or behind a single window. Opening the window, I get three bars and once closed, no reception anymore. Did anyone experience the same kind of problem ?
Is it a general signal weakness problem ?
Do you know if HCT is awre of the problem and if this could be corrected using software ?
Thx for your help !

what about different 3G phones? are you able to get good reception inside the house with them? it may not necessary be Hermes/TyTN fault..

Thx for your reply...
As soon as I get outside, I get full power for the 3G network.
I tried it at another place and get the same results... I also found other complaints here:
http://forum.mypdacafe.com/viewtopic.php?t=10308&start=15
"It has been reported that the UMTS (3G) reception of the MDA Vario II (HTC Hermes) is not strong enough. As reported in the German CONNECT magazine, they had problems connecting to UMTS networks, especially in areas where the signal was weak.
Let's hope that this problem can be fixed with a simple software update, otherwise this could spell trouble for HTC. The problem should be the same across the board for the other brand names of the Hermes.
I hope Dopod is aware of this issue and get it solved before launching their model in Malaysia or anywhere else. "
What about your reception inside a building ???
I am concerned because the signal is nothing but weak in my area !

I live in London (zone 3) and I'm getting the same thing. Inside my flat reception alternates between no UTMS or 1 bar - even though standard GSM signal is full strength.

I found an explanation. The building where my office is located has special protection... Sadly, it blocks only UMTS signal, GPRS and GSM are not affected. Maybe someone can help us to understand why UMTS seems to be so sensitive to this protection ??
You may try another building and see if the problem occures. For me at least, it doesn't
Hope this helps.

Lio

This could be a typical situation as UMTS generally runs at 1900MHZ and above in Europe/Asia. The higher the frequency, the worse the building penetration. The only fix is very high density tower distribution. I had a lot of issues with GSM 1900MHZ in USA too. Once Cingular lit up the 850mhz band my building problems went away.
I was wondering if this would be a UMTS issue....

yah.. it does seem that UMTS signals are definite weaker in general.. but i guess it is still developing/rolling out in most countries so let's give it a little time eh?.. really hope it gets fixed soon tho!

hi People! i have the same problem with UMTS with my Hermes: im my flat my nokia phone can discover all the italian network (tim, vodafone, H3G and Wind) but my pda can only discover vodafone and tim. i changed radio roms but the problem remain. if i go outside, the signal can be discovered and fixed. the sad thing is that the same phone (htc hermes) of my girlfriend works in my flat perfectly! i have got the same radio rom version. do you know a way to "extract" radio rom from my girl phone and put it on mine? thanks...

Ita Rom GPS enabled and 3G UMTS lacking

I've done the upgrade and all goes well but now my P3600 doesn't find anymore the 3G Umts net of TIM Italy. Edge band is at full signal but it can't find TIM even forcing in the settings in Umts.
Anyone is experiencing this problem or a weaker UMTS reception after the Rom upgrade?.
Thanks in advance for replies.
Ciao Olaf

Hi,
I have Wind ITA but even with the original ROM or with the new upgrade 3G is not working since a few weeks...
It gets disconnected, or even connected drops calls, you cannot even make a call...
I don't think this is related to phone firmware as I've tried my sim card inside another phone and it was not working again in the 3G mode..
It's a very strange issue, seems not related to firmwares...but seems a general problem (at least for me)
I'm very happy with Edge mode!

My P3600 with a 3 sim has no problems but with the tim one yes.
My Tim sim in a Nokia 6630 phone works flawlessly in Umts.
I'm also happy with edge mode but a few weeks ago I had also Umts working.
Thanks for the reply

Xperia X1 signal problems. Weird.

Hi, i'm from Canada, PQ, Montreal and another mate in this forum from Canada, Vancouver is having the same problem.
For the first 10-20secs after the X1i has been booted succesfully. We get the G status icon(GPRS signal) in the corner and get 2-3bars of signal, during these times, we can call/text or receive calls. After this, the G signal will be replaced by E signal (Edge), this is when i cannot make any calls nor receive any calls nor send any message. I tried this while i was in the streets in a open sky place. I tried my friend's phone and i had FULL SIGNAL (its an nokia 5800 xpress) , i tried my other phone, nokia n95 8gb, i get sky rocketing signal as well.
So the only way to call me, is to keep on trying , hoping i get GPRS status. I have tested my mom's sim card prepaid , to see if it relates to 3G internet or something , still no luck. Anyone from canada having problems?? I'm with rogers. They use 850mhz/1850mhz , i have disabled HSPDA and seletected these two bands, still no luck .... I cannot update the radio rom because its locked ....
Please help =(

perhaps we might have to unlock the phone with Fido to use voice calls on edge? i'm having the same problem. ;(

Perhaps you have to call fido to disable EDGE and use GPRS only ... i'm gonna have to refund my x1 =(

Initially, Fido worked basically with 1900MHz but since the acquisition of Fido by Rogers in 2004, Rogers integrated the networks extending coverage thru 850MHz...
Better get the X1a or change provider

I live in sweden and I also have problem with my signal. it just disapears from time to time.

Same problem here on the other side of the world; in Abu Dhabi. Sometime the signal is completely lost!

is it possible to disable Edge?? THe "E" symbol only indicate edge reception but we are not technically connected to it. Can i actually ask them to cut Edge reception totally?
I only have the voice plan in the first place.

Problem with 3G Coverage in Sweden / Tele2

Hi,
is there anyone else that have problem with the 3G coverage in sweden? I'm using Tele2. Especial when the phone is "all clean" like after a rom update or hard reset.
On places i know there is 3G coverage it only says GSM, i have try the band settings and then i got 3G , BUT when it's out off 3G range i have no signal.
I tried my sim card in a Sony Ericsson, then i got full 3G coverage on the same spot. I got a new sim card, and no luck with that.
My friend had same problem with his phone, using Telenor. The strange thing is when we played around with the settings and left the phone on WCDMA a few days, then shift back to Auto in Network type it seems to work pretty good UNTIL i got the new rom. I tried the same metod and had no luck this time.
Anyone else that have experianced problem with 3G coverage in Sweden?

I experience the same problem with Telia. I had no problems before the last ROM-upgrade that came in april. Now the reception is very weak and the signal is just one dot in places there it was full before the upgrade. Please keep in touch if you find a solution.

I got the same problems and havnt done the new rom update yet, i think the 3g reception just was this bad and never thought about maby its the phone.. So if its someway to solve it id be very happy to know

As far as I know rom has nothing to do with it. Upgrade your radio

I think i found a solution that works.
I call a few people and found out this, go into Phone Settings, found the tab Network, put the "Network Selection" to Manual, press "Set Networks", wait a for a moment and when you got the list, move and check "Sweden 3G" (i got 2 of them) to the top of the list and after then put you provider below Sweden 3G, i got 6 Tele2 under and make sure that all are checked. So my list looks like this, (make sure that you have 3G on the spot you 're at when searching for networks)
Sweden 3G
Sweden 3G
24007
TELE2
TELE2
TELE2
TELE2
TELE2
After this i got 3G right away! And i have seen a gsm signal also when i lost the 3G.
Sweden 3G is a "network" that all 3G providers in sweden use. Then it up to your provider to put up more antennas for better coverage. So if you using Telia,Telenor,3,Tele2 etc you should use Sweden 3G.
It must be a problem with the "Auto search network" thing in HTC. The HTC Support lady told me that she got some calls about this thing, and not only for Touch HD.
I Tried with GoogleMaps on the way home from work, and it works perfect, and at last i got the speed of the map update thru 3G .. Realtime at Satellite View.
Tell me if it worked for you guys.

drgregur...you need more people to call.

Tele2 and Telia(TeliaSonera) has their own 2G/GSM networks but share their 3G Network called Sweden 3G (SVENSKA UMTS NÄT) between themselfs.
Telenor inherited the old 2G/3G Network from (Europolitan later bought by) Vodafone who fled the Swedish scene years ago.
3 (Tre/Three) Has its own UMTS/3G network, but no own 2G network.
As you are a customer in this mixed Tele2/Telia network, you need a 64K SIM card. Speak to your customer service, and they will be able to help you.
I know that at least Telia is blocking less than 64k SIM cards in their 3G network.

I cahcked, and i got the 64k simcard already. Same problem, seems to be some problem with the phone. My friend uses telenor and got smiliar problem. I running on my solution that i wrote above and it works.
