GSM connection drops in Belgium & Luxembourg

Hi guys,
I had a strange problem this weekend, my P3600 (bepe rom, dont now the version), works fine in Holland. But when I drove into Belgium the phone switched over to the Belgium T-Mobile, and the connection was gone! The phone tried to re-connect and each time there was an connection for a few seconds, and then it was gone again.
This lasted no matter what I tried. I used the connection Wizard to set the settings the the Belgium network, but that didnt work also.
The phone became terrible slow and even the GPS function was affected (tomtom was not able to find the gps device). After shutting down the gsm with the commanager everything worked fine again, but I was not able to make a call obviously. Back in Holland the phone switched to the Dutch Tmobile and calling was possible again.
Has anyone have this problem before?
regards,
Ron

belgian user here, and never had those kind of problems. maybe the problem is the operator you were supposed to switch network to (depends on your local operator, and which belgian operator he is supposed to work with). maybe you should try switching the band manually to avoid 3G connections, and to force GSM connection. these are the only kind of connection problems I've met here in Belgium...
hope this can help...

I use Vodafone and just finished a trip to Luxenburg, Belgium, France and Germany and then back to Netherlands. I use Karmba ROM and had no problems..

thanks for the quick replies guys!!! i tried to set the gsm operator mannually, but it was pretty hard doing that, as the phone was occupied searching for a network. (errormessage "phone busy"). there is a list with preferred operators in the phone settings part. i think that could be the problem. can somebody with a positive experience post his/her settings? For T-mobile Holland that is ofcourse.
thanks!!!

ps. 3G was switched off

Whos ROM

Whos ROM are you using? Try Karmba_a....v.3.0

For good reception in Belgium you really should use one of the big three operators: Mobistar, Proximus and Base.

maybe a problem of the radio rom?
what version are you using?

belgium doesnt have a t mobile network afaik

Try a different radio rom.
Here you are some,I hope I can help you.
Bye

Indeed, that's why I recommend only the 3 main operators.

tnx guys!
I will give my Trin a new Radio rom and check what will happen then, it can't be that difficult I suppose
btw I used al the operators my phone was able to see, and it didnt make a difference..... strange....
If I have more problems, I will drop a line
tnx again

[Q] T-Mobile G2 on AU - Vodafone

Hi everyone,
i recently picked up a G2 on a US trip and am currently trying to set it up to work on the AU vodafone network.
i have gone through the sim "unlock" process, so it should be free to accept any sim card. (it also doesnt prompt me for an unlock code anymore, so im assuming it worked)
when i put the vodafone sim card in the phone, it detects the sim (there is the sim folder in the menu, with the vodafone sim options) and when i use "*#*#4636#*#* i see that there is something in the signal strength (-97dBm 8 asu).
BUT
when i goto settings ->wireless & networks -> mobile networks -> network operators i get an error saying "error while searching for networks"
any ideas?

Shouldn't this be in the G2 forum, not the DZ one ?

Thread moved to G2 General.

I am very interested to know how everything works out for you when you get it resolved.
Im moving to Melbourne from San Francisco in 3 weeks and I am on the fence if I should get a Iphone 4 or a HTC g2
*currently own a HTC Evo ..sadly i have to sell it

welcome to the club my friend
Unfortunately we have the same issue as you but we haven't find a solution yet. So far i have figured out that the phone after unlocking cannot read properly CID and MNCMCC codes from sim.

jee... sounds like the club to be in

5 days now i am trying for a solution. So far nothing to say. Just that users with same problem increase day by day. This might be good as htc will have to pay attention.

i dont know if its me, or if anyone else has noticed this, but if you change the band (auto - USA - Euro - Japan - Aus - Aus2)
then go and try to search for networks, the speed that the error comes up is different... its always the same error though....

You are right about that.

hi, i guess i need to join this club .. any progress for the solution?

I'm using a G2 on Vodafone AU and having no problems at all ...
If I click search networks it sort of just stops immediately with VodafoneAU down the bottom.
The one issue I'm having is that numbers are formatted for US ... anyone know how I change this?
I'm not sure if this is a real long-shot but I had some strange problems with my old Vodafone sim in a HTC Magic. I ended up just going into a Vodafone store and asking for a new SIM and the problems vanished immediately. They give you a new SIM on the spot free so it may be worth a try?

Is your phone working unlocked with the tmobile sim? If it isn't you're got the problem a lot of people have been having with unlocking the G2.
Otherwise, try rebooting your phone with your AU sim search for networks automatically and enter your APN settings. Alternatively if it doesnt find networks, go to Vodafone to get a new sim card. I'm also on Vodafone and I'm not having any problems with my current Tmobile Phone (Cliq) and G2 coming in the mail

Fixed by rooting and gfree
Hi! I had this exact same problem: unlocked a T-mobile G2 bought in the US so that I could use it on Greece's Vodaphone network. After unlocking and trying to check for networks, it would just say "Error while searching for networks".
Solution: I found the solution here: http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Subsidy_Unlock.2C_SuperCID.2C_and_Radio_S-OFF which describes an extra security measure that was taken on these phones and why you get this error because of it. The fix, described in detail on that page, involves routing your phone and then running a program to change this security "feature".
I followed the directions on that wiki page and it worked perfectly! It now connects to my vodaphone network here, and can see other networks that are around.
Note that as this is altering the software on your phone, it probably voids any warranty. But, I'll say with my US t-mobile G2 it worked very smoothly.
Hope this gives some insight to any others having this problem!

No service?

This is a weird one.
Just bought a Desire HD, the guy said it was unlocked. It come with a Orange sim card inside. It had a signal.
I took it out and stuck my giffgaff sim card in there and it says no signal, not "network locked".
So i tried texting my mate, and it sent some how after saying that it had no signal. So sometime later i get a reply saying "Sup" from him.
It still says no signal. I tried another giffgaff sim and that also says no signal. i tried a Tesco mobile sim and that says no signal.
And somehow, without the wifi on, it downloaded a htc update.
I then tried the original Orange sim and it still works.
What the heck is happening?
Thanks

Sounds almost as if it's network locked, or that the data network is set to use orange only Settings>Wireless & Networks > Mobile networks >network operators. If that doesnt work you could always try the advanced ace hack kit (Google it, as it's no longer available on XDA) to give you super CID which will allow it to work with any network.

Ive tried choosing 02 UK as the operator and it says "Your sim card doesnt allow connection to this network"

Now, I don't get this. I'm replying to this from my Desire that says "emergency calls only" without the WiFi on and not connected to anything. What the heck????

Yes it is rooted. Well, it wasnt but it is now.

Bump.
My DHD is running:
Android 2.3.5
Sense Version 3.0
Software number 3.12.405.1
Kernel version:

Baseband version:
3.12.405.1 CL199157 release-keys
And it still says no signal with my giffgaff sim. But works fine with an Orange sim card.
Ive unlocked the bootloader just via the HTCDev site.
Please help...
Thanks

If you unlocked the bootloader to flash roms, relock it and unroot using the ace hack kit. It's going to save you a lot of trouble.
Regarding your giffgaff sim, no idea.
Google to see if there is a way to find out if you are actually sim unlocked.

Oh ok.
I wanted to try and flash anither radio to see if my giffgaff sim would work then, will it make a difference?

Nono..... Do not flash a different radio. Do not experiment. First find out whats up with your cell.
I edited the previous post.

Right, i have SuperCID, and that means unlocked? (hope i am right)
I shall check it again.

silly question but have you set the APN correctly ??????
noticed your already getting assisted on GG forums why do you need multiple forum assist ????

I need multiple forum assists as i dont know if it to do with the network and my sim or the phone.
The APN is set correctly, my phone shows no signal, all the time, with a giffgaff sim inserted.
But the very strange thing is that, sometimes it will let me use the internet. And i am not connected to wifi?

Ive contacted htc with my problem and they just said hard reset, which didnt change anything.
Still have the same problem...
And i cant find any solution...
Can anybody help me!?

Bump!??!?!?!?!

Have you tested a different sim on your phone? Does it work?
Have you tested your sim in another phone? Does it work?
Who do you think you should contact?
Sent from a dream.

Decided im gonna sell this DHD and maybe get another one.
No one has helped me with it so im guessing no one has had this problem. Ive tried everything, so the phone is going on ebay.

No service - HELP!

Hi Everyone.
Stock O2 ICS- rooted - bootloader unlocked
I've recently bought used HTC One V locked to O2. Problem is gsm service never worked for me.
WiFi, Bluetooth, GPS are fine but emergency call only.
I've tried different sim, 2 custom roms, hard reset and no lucky.
Under mobile network setting I cannot swap between WCDMA only - Auto - GSM only, it is sticked to WCDMA/GSM Auto only
When push *#*#4363#*#* Cannot change network mode too, WCDMA preferred fixed only, if going to radio band selection cannot choose any (Automatic, EURO Band etc) just got message "Set [automatic or any] Unsuccessful.
What is weird, When I turn mobile data on with correct APN for my provider (currently giffgaff) I have gprs running and can send and receive data, but with my other phones I had before my service has been alwaysfast as 3G and HSDPA, not "G" like now.
Please see below my screenshots, I've checked my mobile network with many apps and there is what I've found

Ok this may seem a very stupid question but it happened more than once. Are you using the little piece that covers the sim card? That has contacts in it, without it there is no signal

If you still have warranty, run a ruu so it goes back to stock, and take it to the HTC centre. If you are lucky they will recognize it as hardware problem and give you a new one. Remember to tell them it never worked, and if they ask about root or stuff, you don't know about it

No I don't have a warranty (it's second hand and a have no seller contact anymore), otherwise I would not asking here. Looking for somebody who solved this, if.

DINC2 unlocked but doesn't recognize SIM in Panama...help!!!

hi. i just got this phone in the states before coming down to panama. it is verizon, but i called them and they gave me the code and now the phone is unlocked....but i can't get coverage here in panama. i've tried sim cards from a few of the local operators and none of them seem to work. i sure hope someone can help....here's what i've done so far: (oh, pls b patient, i'm a bit of a technophobe)
-unlocked sim. phone gives me sim lock is disabled message....that means i'm good to go, right/
-set phone to gsm only mode.
-software is androaid version 2.3.4
verizon global services told me that everything was as it should be and that the phone should work w/ a local sim card so i'm not really sure where to turn to......hopefully someone here can help. verizon also told me that the phone should work on the frequencies here. i have a claro sim card, but have also tried movistar, digicel, and masmovil. i was told that they use either 850 or 1900.
so, i'm totally stumped. hopefully i'm missing something stupid....btw, tried the sim in other phones (from europe and panama) and it worked w/ them. don't think it's a hadrware problem, but am i missing something? is there a setting change? do i need some kind of software update?
thanks!

update- get cell phone reception w/ gps on
don't know if this will help anyone get to the bottom of this issue, but i realized that when i have the gps on, i get full bar coverage. unfortunately, i can't leave the app on in the background. this makes me think it could be a hardware issue....bad antenna? anyone have any ideas

Same problem
I have the same issue as OP. Got my phone sim unlocked, and it runs on SenseMOD-2012-05-18-225643 Android 4.0.4.
For once I did a factory reset, skipped verizon activation (can´t do and won´t work because I´m not in the USA and do not have a verizon SIM or service), set my network preference to GSM/WCDMA, and the network wasn´t working.
Rebooted, my network is identified as soon as it starts, but then it goes to "No Service". Try to search for network but my carrier does not appear.
Any help?
EDIT:
Playing around with the phone, setting GSM as your network and restarting the phone let me make phone calls. No internet though and the APN was configured correctly. The "E" symbol for the internet blinked once in a while, but never got service.
Also, playing around some more, got my phone to not recognize the network again by removing the SIM another time. This sucks.
