Is it OK to have Tmobile radiostack 6.21 with AT&T servi - Upgrading, Modifying and Unlocking

Hi,
I have problem with my AT&T official radiostack A.20.10. I got drop frequently. In the same location, the phone couldn't pickup any signal when another Nokia working just fine. I wonder if upgrading to Tmobile radio stack will help.
Which radiostack is better for international compatibility A.20.10 or 6.21?
Thanks

To answer you question, Yes! :wink:

Help me PLEASE! My phone can't find a network :*(

I've got a SIM from Orange, Israel, thats supposed to work overseas as well. I am now in Montreal, Canada, and the SIM does not work. It shows as if it can not find a network. That SIM worked just fine on my phone in Israel. I tested the SIM on my friends Nokia 6600 here in Canada and IT WORKS for him. I've upgraded the radio to 1.15.00 and the windows to Tuma 1.4 beta but nothing works
I've gone online to see if my phone supports the GSM frequencies and it does, it supports all of them.
So I manually added the Rogers network (Which is the network that my friend with the Nokia 6600 is on) by going to the Phone Settings, Network, Set Networks. I also tried adding Tmobile and cingular, but no luck. My friend's Nokia 6600 is also from Israel and is also using an Israeli Orange SIM.
Please Please Please guys, if anyone can help me it you guys, I really need this phone to operate :*(.
I'm willing to try anything. I just have a strong feeling that it has to do with the GSM Frequency
Phone Type: XDA IIs
Provider: Orange, Israel
ROM Version: 5.14TuMaWWE
ROM Date: 03/02/05
Radio Version: 1.15.00
Protocol Version: 1337.45
ExtROM Version: TuMa v1.4
Help please
Please, does anyone have any idea to help me out with his issue?
are you the same guy who posted this concern just a week ago? i already replied to your post.
And please dont double post

WIFI => HTC P3300 variant (MDA 3 Compact)

Hi all,
Firstly, I think this is an excellent phone!
I have the T-Mobile variant (MDA compact 3) but I was gutted today when I found out that T-Mobile de-activated WIFI on it.
Apparently it can be activated ... is there any truth to this? Is there any way to get WIFI working on this phone? Are there any firmware upgrades or similar available?
Thanks alot,
Porac69
theres no wifi chip inside the device. cant be activated through software since theres nothing to activate.

If a single operator don't work...

Hi to everybody!
I love this forum becouse there are a lot of kind peolple and becouse i usually found here the answers to my question
I bought a T-Mobile MDA (htc hermes, tytn) with simlock. i used the unlocker in the same way i did with the hermes of my girlfriend. Now my sim is accepted, but at home i have no signal. my operator is WIND (italy) and it can be discovered and fixed if I go outside.. At my home Wind signal is well as i can see by other phones with wind simcards. when i look for networks on the hermes, it says there are the two other italian networks (TIM and Vodafone) but not the one i need. the problem appear only with wind simcards and other sim works well. i've changed the radio rom with upper and lower, but the problem is the same. can someone help me? thanks a lot!
in the start/systems/settings/device information, what is the radio version? is it wm5.0 or 6?
now is 1.50.00.00 but before i used the lastest (1.56.70.11) with the same results. wm6 pro original by t-mobile. thanks for your attention!

looked like the italian releases comes with 1.47.00.10 so you may want to tryt hat.
i used radio rom 1.47.00.10 but it's the same... in the same desk my htc hermes and my nokia 9500, both with a Wind Simcard: the nokia fully working, the other one says "no service" :-( but my answer is why only with sim of this brend?

and you swapped sim cards?
I have two different sim by wind and i swapped them, but the one in the htc phone never works. if I put another sim, like a Tim or Vodafone sim, it works well! damn.. :-( in the same place, htc can't discover Wind Network and Nokia or other phones can (and i found the maximum signal power..)

In the phone pannel of the settings there is a bands page, make sure its on automatic.
yes both first and second options are on "auto"...
well the only thing i can think of is wind is still a growing network, link didn't work the nokia would probably pick up the E900 frequency, compared to the hermes only GSM900/1800 which is still expanding, as you said outside your house it works OK. You'd have to wait and see I guess how the expansion is going.
dear zocster, Wind is a big italian mobile company, and the same sim card in the phone of my girlfriend (the same htc hermes, t-mobile branded too) works perfectly!!! :-( do you think i should ask to an htc tech center? i'm so sad... ;-) thanks a lot for your time, and thanks to veyka too!
I HAVE A NEWS: if u use a H3G sim on my HTC HERMES (www.tre.it) my phone discover only the roaming network and not the H3G network... can this new info be useful to understand what's going on to my phone?

Diamond 3G works on IDEA, VODAFONE but not AIRTEL

hi friends.
i have diamond 2g india version. i also wanted to buy diamond 3g. a friend of mine is offering me diamond 3g which is security unlocked but am not sure if its sim unlocked. only vodafone and idea networks worked on it and not airtel. so i tried updating its radio to 1.11 and also its rom to swtos lite and now even vodafone and idea is not working on it.
that is no operator network works on it now. what do i do.? also i wanted to tell u that this model is the testing model which htc released to ppl who review the device before its launched. does it makes any difference?
also is it sure that it is sim locked and OLIPRO's sim unlocker will solve my problem?
?? help plzzzz!!
i am sorry . idk bout the 3g ... try with another 3g phone
Airtel's GSM Network frequency is different than that of Voda / Idea and BPL.
if ur device could work on voda and idea that means it is already unlocked. Just try and insert another sim and confirm that.
Also I would suggest Radio 1.08.25.20 which is quite stable.

I recently went to India and took my unlocked UK Diamond there and it worked on ALL three of those networks. I just left the network frequency/band on AUTO.

3g in argentina please help!

hi, i have a brand new rhodium t-mobile version, flashed with the nrg rom feb 1st.
when i use the data connection the phone connects to the edge network, while the same sim card connects to 3g/H on a motorola milestone. i read on google that 2 or 3 users (the phone isn't sell in argentina) that have the same problem...
the 3g network in argentina works in the 1900/850 band, so i have it configured that way but it doesn't work.
does anyone knows how to solve this, please?
thanks in advance

3G with the T-Mobile version (RHOD210) works on the 1700/2100 MHz AWS spectrum. You will not be able to use 3G on your network with this device. There is no fix or work around. This is a hardware limitation.
EDIT: You should have gotten the Tilt2 (RHOD300). This is the AT&T branded version that has radio hardware which supports your network.

ok, last question, why in the band section it has the option to use 1900/850 Mhz?

that´s what i thought that it would work..

If it truly does support switching bands, as the link you posted would indicate:
http://support.t-mobile.com/doc/tm5...5611&navtypeid=6&pagetypeid=7&prevPageIndex=5
Then, I would recommend flashing the Stock ROM. Then see if you can get it to work with the stock T-Mobile ROM. If you can, then it probably is possible to do it using an Energy ROM as well. But, I don't think it is possible.
I am not that familiar with T-Mobile phones, since I use an AT&T Tilt 2. It seems unlikely that this would work, since in the United States even the T-Mobile HD2 doesn't get 3G when SIM unlocked and switched to use the AT&T network with an AT&T SIM.

That band switching feature is to set network preferences for your carrier outside of the US. The radio hardware does not support UMTS 3G. You will only be able to get EDGE speeds at best from this device on your carrier. You need the RHOD300 (Tilt2) to get 3G on your network.
that´s a bummer
thanks for your answers
