I have a galaxy tab 7 from T-mobile. I have updated my firmware to newest overcome rom but I don't know what modem I should use for it. I live here in the Philippines which is part of Asia. I want to use a modem with call and 3g function. Additionally, when changing modem, will it wipe out my system? Thanks in advance.
I have the T-Mobile SGH-T849 too.
Use JPZ modem in Asia/Australia/Europe should be fine.
No, flashing modem will not wipe your system.
After flashing go to setting About Phone and check your baseband
it should have changed to something-something-JPZ
yup, I'm using JPZ on my tab, but I don't have 3g.. i only have edge.. can I still revert back to having 3g instead of call?
which network in the Philippines? maybe we can find out what frequency your network use.
It is weird. I thought asia uses GSM 900/1800MHz and HSPA at 2100MHz, which is what the JPZ does.
The original modem (JJB) can be found here.

But T-Mobile modem is meant for T-Mobile user to have 3G, even them won't get voice call with it.
Are you sure your area has good 3G reception?
I'm not familiar with frequencies and such, but i'm using Smart here in the Philippines. Can you help me determine what network I should use?
http://obsessivecoder.com/2010/09/19/philippines-gsm-frequency-band/
Smart Communications 900 MHz/1800 MHz W-CDMA (UMTS) 2100 MHz
Exactly the same as other GSM I know in Singapore/Indonesia/Australia
Can you check your setting just to make sure you are not restricting your wireless to 2G only?
EDIT: I am not sure if you edited your post. But I thought I read you get E only.
Now I can't see any of that in your post.
Do you get mobile network working at all?
If not, then the issue is with your APN.
You need the right APN for Smart
i've set it on wcdma but it does not pickup any signal. i still only have edge.
Menu -> Settings -> Wireless controls -> Mobile networks -> Uncheck .. only 2G
I got more info on APN:
APN Settings for Smart Bro
Postpaid APN: smartbro
Prepaid APN: smartbro
APN Settings for Smart Buddy, Smart Gold
APN: internet
i'm still on EDGE.

forget about the references to 850MHz,
access the menu and make sure you have stuff selected for 900MHz 1800MHz and 2100MHz
normally we have 3G on 900 and 1800, and 3.5G on 2100MHz
still not working
you can confirm that the same SIM card in other phone, at your present location, gets 3G?
yup, on my galaxy y, 3g is ok
and APN in that phone is the same?
EDIT: try other modems. KM2 for example
went back to t-mobile modem for the mean time. will try out km2 later. from the modem list, most of them are for gingerbread 2.3.3, but mine is 2.3.6. will there be any conflict with that?
nope.
even froyo modem works.
we use JPZ through to ICS as well.
Does T-mobile modem gives you 3G?
yup, it gives me full hsdpa connection speed.
hi mahan21,
Not sure if you are still looking for the modem.
try T959UVJL5 modem from the Galaxy S T-mobile.
I was baffled because I am really sure I get 3G/H on JPZ but I check again I can't.
I even restock to GB stock safe, no luck.
So after searching, I found the JL5 modem
and it works!
3G/H and voice call on T-mobile tab in Asia (Well, Optus Australia but it is the same GSM/UMTS combination)
Get the modem here:

(the one the OP attached, not the multiupload which is dead)
Edit: not sure if this is a switching problem or the way the phone is designed, but sort of figured it out...seems that the Exhibit 4G will auto fallback to UMTS when no HSDPA link is active. Just ran some speed tests and it did in fact hold HSDPA speeds, when done it fell back to UMTS. My GS3 doesn't do this...if I have 4G/ LTE available, it stays with it. Hence the confusion.
I recently purchased a new unlocked Exhibit 4G, have been testing the various roms here...many thanks to the devs...great work! Currently trying AOIP...nice!
My primary usage is on the TMO network, at my RV site on weekends. Unfortunately, 2G is the best I can get in my location, regardless of carrier.
I live in Canada the rest of the time, on Rogers with a GS3.
I was testing out the Exhibit 4G with my Rogers sim, LTE APN's were set up ok, voice & messaging are fine, but data is wonky...I will get the 'H' (aka 4G) icon for a few seconds at a time, but for some reason I keep falling back to 3G speeds. This cycle continues over and over. AFAIK, this phone should support Rogers HPSA+ frequencies (aside from their new 2600), shouldn't it?
So I'm wondering if this is due to an incompatibility with the phone on Rogers, or needing a different baseband, or could the phone's h/w be screwy? This has been happening with all roms I have tried (AOIP, Baked, Slim).
Appreciate any insight.
I have an unlocked Galaxy S4 active i9295 and I cannot get the 4G or the LTE working since I do not have even the option I only have WCDMA/GSM I travel around the world with this phone and now I am in Ireland on 3 and still I am getting H+ showing and not LTE or 4G. Is there a way to activate 4G or is there any special 4G sims ?
I would check your APN settings, seeing how you are unlocked, the proper APN may not be installed to match your Sim, check with your carrier, to make sure they are 4G and LTE capable and get their settings.

Try ShowServiceMode. It should help to unlock LTE band. It worked for me here in Poland, because local career's LTE was locked by my Russian firmware. But using this program I can only switch between phone calls (GSM/3G) and LTE, they cannot work simultaneously.
Thank you guys. One major thing is that why I can even see the option in the settings? If anyone else has some information please help out.
Thanks
I seem to cant get any LTE connection on my at&t moto x.ive downloaded the phone testing app and i cant change it to LTE/GSM or any LTE connection for that matter it stays on GSM auto. Any help or ideas please? As of right now im only getting hspa/hspa+ connection
Google your carriers APN settings and see if yours match.
Other than that, it can only be a Sim card issue or carrier issue. Assuming you mean an AT&T model phone on at&t's network.
Or is it on another network? If so.... You may not have the bands supported on the phone that your carrier uses. Nothing you can do about that if so.
I have got moto-x xt1052 running lollipop Asia version
Network works fine in gsm (2G) mode but it shows no service in 3G and LTE mode
Vodafone IN 2G works not 3G and 4G, Reliance JIO doesn't works since it has only LTE
I tried resetting the phone and flashed the stock rom
Run test in *#*#INFO#*#* mode, in SMSC it shows my number
Even flashed the modem files but also it show no service
How can i get back LTE mode?, help me guys
Since a few days ago, my Moto X also has no service, regardless of what the preferred mode is set to. It simply sees no carriers at all. Anybody got an idea how I can debug this? One idea is that the GSM antenna has disconnected itself somehow, but I don't even know where it is.
