i know this is old stuff to most of you but i have got as far as i can on my own. i have a tmobile ppc 2002. i upgraded to wm2003e. ia set ad the following versions rom/3.04.00 eng, rom date/06-12-02, radio ver 6.18, protocol ver 324e4. Now - i put my cingular sim card in the ppc and it works! but it show my current network as att wirless. if i hit set networks it shows tmobile and attws as the only choices. if i change network selection to manual - sometime it will show a whole list of different providers including cingular and when i select cingular it errors out. i can select attws. is there anything i can or need to do? am i good on my versions? thanks for taking time to read this and reply.

If your phone is working ok I wouldnt lose any sleep over it.

O2 branded, Virgin PAYG sim, phone thinks its on T-Mobile?

Have had my wizard for a couple of weeks now, when I bought it, it had the O2 software running on it, its branded externally as an O2. I upgraded the ROM last night but i have noticed that the phone (as before) still thinks it is using the T-mobile network e.g. when i tap on the signal strength indicator or a message comes through, it indicates the t-mobile network. I can receive and make calls as well as text messages and voicemail on the virgin network no problem. After doing the rom update last night i indicated that i was on the Virgin network when prompted when the device was initialising.
So how do i get rid of the fact that my wizard thinks its using the t-mobile network when its actually using the Virgin network. The phone is branded externally as O2? How on earth did this t-mobile identity survive the ROM update. Note i applied the I-mate ROM.
During the ROM update i left the sd card containing the previous ROM image (O2), a backup in case things went wrong, in the device. I noticed that a little after i ran the imate rom update from my host pc a message appeared on my imate mentioning something about the fact that there was an SD card containing a rom image and if i wanted to use this. It was very late and by the time it registed with me what i was looking at the message timed out and the rom update continued. Could this explain the reocurrence of the t-mobile wording. When i reset the device the imate splash is what i see.
Currently:
ROM version 2.16.9.1 WWE
ROM date 2/6/06 (6/2/06 here in the UK)
Radio version 02.07.10
Protocol version 413.1.03
ExtROM version 2.16.9.101
Thanks for any help

Virgin is a virtual mobile operator and uses T-mobile's network. Its common for T-Mobile to show up as the carrier on many mobile phones.

Roaming indication after upgrade
Hi have the same problem.
I have a T-mobile (US) phone; I upgraded the ROM (Qtek test ROM) and since then, the phone shows that I am roaming into Cingular network.
In my area (San Francisco) - Cingular is the actual network operator; T-mobile uses Cingular's infrastructure as part of a deal made long time ago.
So, the ROM is correct but I wish there was a way to disable the ugly triangle (showing that I'm roaming) or alternatively - let the phone know that I'm parked in a "home-network".

Ah thank you for clearing that up. By the way is it true that virgin has been bought by NTL, someone mentioned this today. Not sure who is worse NTL or Virgin UK.
Do you know where i can get the settings for MMS and GPRS, have not checked if they have been set up properly.
Many Thanks
Fergus

it's true...

The operator logo in the dialer does not automatically change when you switch networks / sim cards.
It depends on the image file 'carrierlogo.gif' in the Windows folder.
I have an unlocked T-Mobile MDA Vario with an Orange sim card - this showed as T-Mobile until I updated the carrierlogo.gif file!
If you want to view the network you are currently connected to, go to Start | Settings | Phone | Network.

Have you tried another QTek ROM? Otherwise, it's a possible SIM-related issue. The SIM hasn't received an OTA (Over the Air) update telling it that it is connected to T-Mobile's local switch. Furthermore, you shouldn't be on the shared network anymore since the old GSM 1900 shared network was sold to T-Mobile in CA and NV as part of the Cingular/AT&T merger. I would think that T-Mobile has updated that GSM 1900-only network to broadcast only their MNC (Network Code) so any T-Mobile SIMs registered on the network know that it is a native network.

Country-locked phone?

Hi there.
I have a friend who has an X1. He is reporting that the X1 is working with his O2 sim card and working on Vodafone however it isnt working with his Latvian sim card (in the UK) (i.e. Tele2 and LMT). Are there any settings you need to change in order to enable roaming? Is it possible for a phone to be country-locked?
Thanks,
Lawrence

It might be the phone is locked..then again it might not be.
What does he see when he puts in the card? How long do you wait while it searches for a signal? (Sometimes when I'm roaming it takes a few moments -in egypt I think I waited 2 minutes - it might take longer for Latvia to register for one or other reason).

thanks for your quick reply!
I dont think it is locked because it works on both O2 and Vodafone fine. I bought the phone from vodafone and all of their phones come unlocked.

its more likely that the phone isnt using the correct setting for the service provider... usually when the phone detect a new sim it will ask you if you want to change your settings... your friend may have missed it and didnt change the setting so it didnt work

Roaming is enabled by the origin network, not by the phone.
There is a chance that some of the UK networks don't allow those SIMs to roam on their network, but you would need all 4 for them not to work.

another reason could be too old incompatible sim card
people have from time to time reported rather old sim cards being
incompatible and solved it by getting newer sim card from their operator

Unlocked but shows roaming service

my HTC P3600 was purchased in the UK and was locked on the Orange network. I got it unlocked before moving to Canada to study. I purchased a sim card from one of the GSM mobile operators (Fido). But when I insert the sim card into my phone it shows me as roaming and the network also charges me roaming service rates even though I am not in a roaming area.
I upgraded the ROM from WM5 to WM6.1 and still the the problem is not fixed.
I also used the sim and CID unlocker (http://pof.eslack.org/trinity-unlocker/) to "reunlock" it but that also didn't work.
Can anyone help me out here. I love my phone and would like to use it instead of getting another one.
So please whatever suggestions you have would be welcomed.
thanks in advance

Not receiving calls on Hermes, but still on other phones

Hallo,
I have a world-wide gsm version of the htc Hermes. The device is simlock-free and always has been. I put the official, albeit leaked, WM6 rom on it and it works great. But: last week I switched providers (for better data plans) and here is the result:
Data connection works just fine
SMS works just fine
But, I can hardly make calls and I don't receive any. The problem is not the network, because I switched phones (I put my SIM in a €26 SamSung phone which I use when I go camping) and I receive all of the calls. When someone calls me, they hear silence for about 30 seconds and then end up with my voicemail.
Any ideas as how to solve this? Both my old and new carrier are GSM. The only difference between them is that my old carrier (Belgium, Proximus) uses has a 3G/HSPDA network whereas my new carrier (Belgium, MObile Vikings; uses the network of BASE) has an EDGE network. Both operate on Dual Band.
EDIT: Would a radio upgrade do any good? If so, any suggestion for a radio version?
Thank you!

Come on, 80 views and no reply. Someone must have had an idea!

I did a radio upgrade (1.48-> 1.50) but that didn't solve the problem. Any other ideas?

I have TyTN and similar problem. Installed WM6, and worked fine for a 6 months. Few days ago problem (Strange?) started. I have GSM signal, I can make calls, I can receive calls from fixed lines and other GSM operators, but I can't receive calls from users of my domestic network?!? They get info Connection error? Please, HELP.
Also, when I ask request service for Call Barring I get info "Can't read specified service..."

Change the Sim
Long shot but have either of you thought to get a new sim from your current provider (port your number across if necessary) and see if that works?

I've changed SIM card, it's still same problem! But, with a SIM card of other mobile operators I have no problem.

Sounds like a problem that's related to the network provider you are using. Have you chased down their technical dept for help? All else fails, move providers.
Once had a problem where I could not get mobile signals at home but could everywhere else. Turned out my service provider had issues with broadcasts to the cell near me.
They fixed it and gave me my charges back equal to the time the system had been out.
Good luck with it.
