Hi, was just interested to hear other peoples experience with certain modems in certain countries. Im in Australia and am currently using jpp and was wondering for issues such as reception and data speeds is there certain modems we should use in regards to where we live?
I havnt notice much dif with modems except JPM modem hangs on me often. Currently using JP0 and it seems stable. speed wise I havn't noticed any dif as Optus is always screwed due to over selling its network. Btw you are using optus too
Yeah Virgin using Optus just heard other people saying this modem does this and that compared this modem which doesnt etc just got me thinking cause we are flashing european firmwares maybe we should be using certain one.

Hey Guys,
I have a GT-i9000 (Unlocked) and after a few firmware upgrades I have been noticing worse call receptions (more drops) and worse 3G data performance.
For example, I once had near perfect reception and few call drops along my drive home, now (5 firmwares later) I have been dropping calls like my old iPhone (actually worse) and what is more upsetting, yesterday my friends with their iPhones all had signal while I was getting the no service icon.
While i know the Captivate users can use the i9000 kernels (but swapping out the modem file) I wonder if anyone knows if I can use their Captivate modem file (JG8) instead of the one that comes with JM7 to fix my issues with reception and 3g performance .
What functionality will i lose? I travel to Germany often, will that cause issues with 1900Mhz and 2100Mhz bands ?
Is there any other reason that my signal would be so poor?? I really need help with this.....
Is anyone else using an unlocked i9000 on AT&T and having poor voice calls (signal/drops)?
What firmware are you using now? I would like to see if this relates to my issue.
I'm using JPC on my Bell i9000m and am starting to wonder if the reception is not as good as with JH2... I am contemplating using the JH2 modem file with JPC to see if it helps...
Coincidentally, I'll be in the US in a few weeks so I want to ensure I have good reception on AT&T as well.
i am using JM6
Just tried the modem from the the Captivate JG8, it would not even install.
So I am running JM7 now.
I will see how many dropped calls i get today.
JPC stopped booting for me and I am on JM7 as well - I'll post my comparative results as well tomorrow.

Just did some tests with my wife's iPhone (3gs) and my galaxy s.
Passing the same dead zone and her phone could make calls and mine would fail.
I wonder if i put it on gsm mode only if that would help.

Hi all,
I own an Australian Telstra-compatible GT-P1000T onto which I've flashed the Overcome ROM v1.6.4. However, i am now using the Tab with an Optus SIM here in Brisbane.
I was simply wondering of anyone knew what the best modem would be to maximize my 3g speed and coverage on Optus. Im currently running the JMA modem, if that helps.
Thanks everyone,

There is a modem stickie. The correct Telsra modem for your region is there.
Hi,
Thanks for the advice but as stated in the post, I'm not using the Telstra network. Doesn't that mean a Telstra modem is going to give me sub-standard performance? I believe the stock Optus modem would be best, but I wasn't sure if using a GT-P1000T made that choice any different?
Thanks again.
They are not "branded", they are just the modem.bin files that work best for a given region/carrier. You can flash any modem you want, some will give better performance than others.
After you flash a modem go to the wireless settings and check your apn settings. If you are using a different modem you might have to enter the values. To get the values google "my-carrier apn settings" where my-carrier is optus, or whatever.
Hi,
Yeah, I realise that, so i was looking to see of anyone on XDA had worked out what modem gave the best Optus performance. Plus, there has been some.confusion over whether the P1000T has a different radio or just a different software to the P1000 since it has the extra 850 band (same problem as the SGS i9000/i9000T debate).
All I was looking for was to see if any XDA users had tested or could recommend a good modem to use for an Optus tab (preferably one with better performance than the stock one)
Thanks.
Your radio has the 850 band? Cool. If it has it, its not software, its in the radio chip. What did you pay for your tab? Can you buy it without a contract?
3G strength poor
Hi. I think I have the same issue. I purchased it as an Australian Telstra unit. I have since had the firmware changed to a non-carrier European version, rooted and unlocked. I use it on Optus. I believe that the 3G signals and speeds could be a lot better. I had a Samsung B2700 and B2710 Antenna Gain increased and those made all the difference to not dropping calls!
I have searched but cannot find anything about adjusting Antenna Gain on my TAB, nor for my SG2. This thread is the closest thing I can find to being able to improve it.
Can a different modem help or is it the radio chip that holds it back, and can that be changed?
*#1234# gave me the following...
PDA : NIL
PHONE : P1000XXJHA
CSC : NIL
Is it strange that the PDA and CSC are empty?
I live in Edmonton, alberta Canada and have a 9000m on bell with darky rom10.2 JVQ band.
the phone works great in town I have zero complaints but as soon as I get outside the city even a kilometer or two it drops right down to one bar then some after to nothing.
now my girlfriend's iPhone 3g has full reception in all the areas mine has none, hers is also on bell so she has been bashing my wonderful phone claiming iPhone superior.
after reading threads I have come to the conclusion my modem installed is incorrect. as there are about 6 or so different modems I'm wondering if anyone in my area can narrow it down for me as I have read different modems are for different providers and areas.
any help would be great!
Change ur modem

I've been using some of the custom roms and have lately noticed that when I do road trips, I have terrible coverage if any at all. I'm fortunate enough to have two other phones on different carriers (mine being telus, work phone is Bell and wife is Rogers) and the other two have full bars. I even used the OEM APN's in the custom roms. Sometimes rebooting fixes it but not often.
I've noticed this with v20O roms but haven't been able to try other versions. I'm wondering if it has something to do with being in North America? I've recently noticed that we've just got a v20i for my carrier that I am now trying.
My question is to other people in NA, specifically in Canada what versions of custom Roms have they been using and if they experienced poor coverage while traveling?

I had same problem with v20o. My phone was v20j from koodo. So I injected cwm into v20j kdz and flashed with that .been perfect since. Check out thread v20j for How too same procedure for v20i hope that helps
Thanks. So you ended up going with v20o? (Zeus I'm guessing) and its OK now?
I'm curious if the region makes the difference.

No injected cwm into my stock firmware and then installed superuser zip worked perfectly. Look up thread root v20j thread I posted
Does anyone know whether Telstra have issued their S3 4G phones with baseband versions other than DVALI5?
DVALI5 was the one that shipped with my handset from Telstra, but it seems to have 3G/4G reception issues with my phone when using a CM-based ROM (currently SentinelROM 4.75). 3G/4G response times slow down a lot compared to when I'm using a Touchwiz-based ROM.
I tried another baseband version (can't remember which one) previously, but it made the connection even worse.
My current baseband is DVBLL3 haven't had many issues at all. I believe its newer that your existing one..
Ive got an unbranded s3 4g and use it on telstra and mine came with/ still on the same one above and havent had any issues
