My signal is horrible. Need help[Solved]

I have had this phone for about 4 or 5 days. When at my house I get 3g and only about 1 or 2 bars. This happened on my Samsung stratosphere too. Could this be a SIM card issue or hardware. I have read about a lot of people replacing this phone and still getting issues with signal. If I do bring my phone in to a Verizon store to get a sim card do I have to revert my phone to stock? I don't know if I should send my phone back or if where I live is just horrible for data. Sorry for so many questions.

Flash another baseband radio and if you are using custom rom with custom kernel then flash stock galaxy nexus's kernel.

Since it is the case for two phones, then maybe the 3G coverage is not good in your place.
Try asking others living around to confirm if they also suffer the same 3G coverage problem. Also try in another place to see if it still shows a weak signal everywhere or only at your place.

I do get better signals in different areas. Even with the 3g and 1 bar my speeds for browsing are decent but I just was wondering if a sim card or replacement would help. Thanks and I will ask some people

If you would like to try another baseband radio as suggested by manumanfred then this thread should help you if you have a Verizon Galaxy Nexus as it seems
Check this for baseband radios if you have a GSM Galaxy Nexus

I flashed the 4.0.4 radios and they didn't change. Should I try flashing again?

Flashing radios makes a slight, if at all a difference. Your best bet would be to keep calling and complaining to your provider, ive seen some success stories where others have been able to get verizon/att to pay for a 3g extender

Edit:Alright thanks. I think I am just in a bad area and I use wifi at my house anyways. Thanks
I accidentally misread the radio labels. The 4.0.4 did install.

I am not sure that an old radio will perform better than the newer one. Give them a try then choose the one that suits you better

Well I am going to have to switch back to the latest. Data barely turns on when on these 4.0.4 radios. I am not going to return my phone because I doubt mine is defective. Thanks to everyone for helping

It would be great if you mark this thread solved by adding something like "[SOLVED]" at the beginning of the current title
One more thing please is to make a habit of hitting the "Thanks" button to those who help you
Good Luck

4.0.4 radios are old. Try running something a little newer. I'm using FC04/FC05. Although honestly I don't really see a difference. Most of the time it just adjusts the timings between switching in and out of 4G... which I have disabled.
I would also recommend looking at a cellular booster/repeater. I work underground in the bottom floor of an office complex and we don't get signal from any carrier. We paid like $200 for a repeater and now we're good.

Rogers I317M LTE drops to 4G during phone call?

Hi,
I have done a search and know that the AT&T variants drops the LTE during a phone call. I recently did a flash with cleanrom 3.5 and out of no where just noticed it.
So I want to confirm that its normal on a Rogers variant.
Thanks

yes because lte is not used for voice calls

And I would be happy if it drops to 4G I only want LTE when im online so it will help save battery big time.

So has anyone addressed this in a Rom? Can it be considering all the radios are in one chip?

Simultaneous voice and data problem

I'm running CM 10 on my AT&T S3. I'm in an LTE area and have LTE coverage. I also would have strong HSPA coverage as well.
My issue is, when I'm on a call, I have no internet connection. There is no 4G/H/3G icon at all by the signal bars (which are full). And when I try to go to a page it says No connection.
Is this an issue with CM10? Anyway I can fix this? I can't seem to remember if the issue was present on stock.

Same here. It worked on stock att

I tried the MC3 today. After installing I was able to pick up a weak signal but as soon as I walked around the house the signal dropped. At the office i had a better signal using the old modem vs MC3. I think I will try the one for t mobile. Thxs

Bajanman,
You saved me several hours. I will download the older ATT modems and see if that works.

I tried one of the old modems and got the same results. I continue to get varying degrees of signal strength. I saw some people saying this could be a hardware issue , any ideas.

That could possibly be it.. could be hardware based problem.
But first what modem do you have now?? J2 is the first one

Bajanman,
I tried all the modems available for ATT with the same results. I have a very weak signal especially indoors and depending on where I am it improves. What kind of hardware problem do you expect to be the problem? Is there any way to check this?

[Q] No service at work. Any help?

Ive noticed since I moved offices, that in my office building I get absolutely no service whatsoever. And there is no wifi password available to use wifi via my phone. So today as I was leaving work and finally got service again, I had 12 missed calls, 5 texts, and 3 voicemails. Is there a better modem to flash that can help? Thanks!

Not exactly. Different locations have different best modems. You just have to try them and see.

Could anyone suggest an updated modem, or one they have had luck with if they are from the Chicago-land area?

You could check the map in the modem thread too. I know its a jumbled mess now, but the info can still be useful.

yeah, i was trying to find my way through it but it is difficult so it hasnt really helped

K. Sorry bout that. Ill be redoing everything in it soon though.

Do you think you could message me about what modem/radio might work better once that forum is sorted out? It really sucks not being able to use my phone at work for 8 hours. Thanks

I may not be able to unfortunately. I messed around a little before and got nowhere. May have to start a new map.
Have you checked T-Mobiles coverage map yet? There just may not be a signal there in the first place.

I never had a problem with my Blaze there. Even at home with the S3 I get maybe 2 bars. Which leads me to believe its the modem. On my Blaze I had an updated modem that made data very fast.

Can I use UVLI6 which is a 4.1.1 modem on a 4.1.2 rom I am currently using? Would that be compatible? i cant remember which way compatibility goes :/

Any modem, any rom, any build. Only make sure you use the right models modems, which it sounds like you are

It will work, but last time I did that I wasn't able to connect to hspa or hspa+ only umts.. If it gives you signal though I guess its better than nothing

You can use any modem version as long as it's specifically for your phone.

This is just strange... in roughly a year of doing this I think you're the first to report that happening. 4.0.4 and 4.1.1 modems have always worked on 4.1.2, and any other combo has worked as well. There are people who still use the LH2 (ics) modem because it still performs better than any other for them.
I think you may have been seeing it function normally though. When idle, its supposed to drop to UMTS to save power and bandwidth. If you check while a transfer is occurring you will see it change to HSPAP.

Has anyone else found another modem that they now use that gives them better signal/data speeds for their Tmobile T999? My work building is a complete dead zone for Tmobile, so I am hoping flashing another modem works. Otherwise, im not sure what else I can do.

I have to refer you to my initial response here. A modem that gives better speed and signal for me, might be one of the worst for you.
Just something to consider, you probably could test 2-3 different ones each day at work. Maybe more. If your main issue is signal, then flash, check service, if none then flash another right away. I could probably flash 5 different ones on a 15 min break if I was only looking for improved signal. Might be a better way than waiting for someone to tell you what worked for them, then testing only that the next day. Its your phone and your time though, so its your call. Just tryin to help
