Dear colleagues,
I have the same problem I also bought a i337 from AT&T USA and I'm trying to use 3G and 3.5G but is not possible my carrier is TIGO and use 1900Mhz band, i was wondering if I install a different ROM for example another carrier or any from factory settings (without carrier custom) could fix the problem, you experts what do you think??
any suggestion??
Grettings!!!

1800 mhz GSM Band Missing

I am planning on going to a GSM 1800 country soon but I only have GSM 900 & 1900 (what i'm on now) listed as choices. Is that because of my current SIM card or is there a problem with my phone?
Thanks,
Daniel
Here a file to enable the band selection.
How do I run this?
It worked-
Thanks!!
I go to the States in August. Work the Magician in the USA ?
Thanks
Depends but most probably:
If you are going to be roaming with your current SIM card then find out which network you will be roaming on- if it's T-Mobile you will be fine because all the Magicians can work on he 1900mhz band- which T-mobile is. Cingular/ATT mostly is 1900mhz also but some rural areas operate on the 850mhz band- either way you should be fine, but find out who's service you will be on to be sure.
-Daniel
Thanks !
I use Proximus from belgium.
by the way, how u know gsm 1800 band missing? how u check it?
in the phone: Tools | Options and the tab Band is missing.
I have the band option, but I can only choose:
GSM 900 (europe)
GSM 1900 (North America)
Even after running the program in the second post.

Can you choose 3 bands?
900; 1800; and 1900?
how to run file?
Hi,
was wondering how you run the actual file.
thanks
Con
Can you choose 3 bands?
900; 1800; and 1900?[/quote]
Yes, I can
no, don't have option
cong
This is the screen I am getting.
I only get
Phone, Services, Network, More
that's why I need to know how to run the program so I can get this extra
BAND option.
cheers
Con
im having same problem as cong... helpp pleeaasseee!!!
Hrb, what kind of Magician do you have?
I'm talking about a T-Mobile MDA Compact with a standard Rom WWE 1.10
And as told: I do have the Band Tab, but I can only select:
GSM 900 (Europe)
GSM 1900 (North America)
And Cong and Castiwo, have you ran the program and softreset the Magician?
I don't know how to run the program, that is the problem

Topaz does not work in US 3G network?

I got the Topaz from Europe, and I tried several ROMs but I just can't get it connected to the US 3G network. I heard the band is different, but is there any way that could possibly solve this problem?
Thanks so much in advance.
Also, is there a "2G" version of Topaz? If so, how can I tell if my phone is 3G or not?
No way to make it work, although if you are on att, you may get hsdpa in the few areas that actually have it. not sure what you mean by 2G, but it should connect to EDGE just fine

Take a look a the band located in your phone's option section. 3G would work if UMTS is 850, 1900 coupled with WCDMA

[Q] T-Mobile 3G <-> Telcel Mx

Hello everyone, im from mexico, i just bought a DVP from T-Mobile, i think is unlocked cause when inserted my sim card from "Telcel" i can make calls, send/receive sms, etc, always have "E" letter besides signal metter, however i would like to use "3G" network, as i found on this forum seems to "E" means edge, and T-mobile is not compatible with telcel 3g, is this correct? just want to confirm this and i want to know if ATT version is compatible to 3G from telcel, thanks in advance, BR
As far as I know Telcel uses the 850 band for 3G. The T-Mobile version uses 900/1700/2100 and hence wont support the Telcel 3G. The ATT version has the 850/900/2100 band and hence theoretically should support the Telcel 3G. It is advisable that you confirm with someone in your area if the ATT version works, because as per specifications it should work. The TMobile wont work as it does not support the 850 band
Thank you
Thanks, very clear and direct, also quick answer, so if i understand correctly its kinda hardware diference, right? so no way to convert or configure an aws to pcs or backwards.. thank you!

It's not possible, at least on phones. Each specific submodel likely has different amps for whatever bands that submodel supports. They're (very likely) physically different.

Did I buy a bad phone / wrong phone?

Just bought a galaxy note n7000.. when I poped in my sim card it does now work..
I am with mobilicity they use AWS, with bands 1700/2100
http://mobilicity.ca/
Is there anything I can do? Other than beat the hell out of my brother who told me it will work?

beat away... now it will work but on edge... there is a thread on trying to create a radio to work for tmobile which is the same as yours... now they have got the i717 version(usa att) to work but not the 7000... give these guys time they always come through... but until then its edge only....
ps you may find someone with a i717 wanting a 7000 and might trade....
Frequency used by Galaxy note :
Also known as Samsung GT-N7000, Samsung I9220
General 2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 700 (region specific)
Since your service provider uses 1700 and 2100, then it should work.. just activate your 3G network in your wireless settings.
Good luck

ok...the 1700/2100 is correct but like tmous they use the 1700 as the data so activating 3g is going to do nothing.... there is a 1700 freq in the chip, but it is locked hence the need for the custom radio.... btw that thread is in the general forum... as for making phone calls, well if it is unlocked it should make them just fine...
is it telling you something when you power it on? does it have signal strength?.... need a bit more info....

Normal GSM Functions (Calls/SMS) should work on 100%
There is something wrong with either the phone or your SIM Card/Provider
Call Customer support and explain your problem and be sure to tell them that the problem is Calls/SMS and you are aware that 3G will/may not work!
Maybe they are blocking the international Notes for some reason?!
It never hurts to ask them!
You will NOT get 3G to work if your carrier uses 1700mhz for AWS. Tmobile and as far as I know Wind use 1700 AND 2100 for 3G data. Having just one band (in this case, 2100, will not cut it). In any event, you should still get 2G data and be able to call/text.

how can test if this is problem with the phone?
I tried another sim card form rogers wireless and it works right away.
my sim card has "no service" then after 5 mins the icon changes for a stop sign with a live through it to actual bars.. the no service changes into emergency calls only.

OK. Then your phone is OK. Call Mobilicity customer support and explain everything! Tell them that the phone works with Rogers SIM and not with yours!

S5360L band changing ?

hi
i have here few PCS of S5630L
its same phone but bands are not the same.
HSDPA 7.2 850/1900MHz
anyone think it can be changed via software ? or its a hardware issue ?
if so can i change bands filters ?
thx
anything ? anyone ?
it can never be done,
it is the internal radio which transmits and receives frequencies,
which is a hardware thing,
if i got you correctly S530L is CDMA and you want a GSM band

This model is not cdma, irs gsm model fits to some countries like brazil and argentina.
so this phone works only on quad gsm 2g network with no, but on 3g networks it works only on 850/1900 and i need 2100
On older nokia phones we changed anttena duplexer and bands filters and it did the job.
On newer phone like i9000 we can change bands via programing menu.
I just wonder if it can be done even with hardware changes.
Thanks
Anyone ??
I tried *#*#197328640#*#* but not working
