On my Captivate, I could customize the radio to remove and add bands. Is there a way to do this on the Inspire? I live in an area where we have so many towers that even though I'm considered in the "best" coverage zone, my phone rapidly hops towers. Setting my Captivate to use the 1900 band only eliminated this issue entirely.
I may have to return the phone if I can't do this because I constantly drop calls and data. The worst is when I am on a phone call - it will go from HSPA to EDGE and then the data connection icon disappears entirely until I get off the phone and/or the call drops - my Captivate did this as well until I set it as 1900 only.
I think one of the custom roms had this option, just can't remember which one. I know one of the desire based roms had a selection setting to force it to one or the other or to set it to automatic.

I would be extremely interested in this. I am considering making a post in development about it because seriously, I am sick of trying to make a call and it fails because there is no signal, then I wait 30 seconds and I have full signal, get on the call, and it drops out.
This would be sweet to have, my phone is constantly doing the dame thing.

Honestly, its a trade off - on my Captivate, I have to lock it as WCDMA 1900 - which means that when I drive somewhere that DOESN'T have 1900 (pretty rare in Colorado) AND HSDPA or 3G, I can't make a call but switching the band takes all of 5 seconds. I can tell you that 1900 here at home though locks and doesn't let go whereas 850 does. My SIM is currently in my Captivate because I'm going to call them and try to make a case for a microcell again.
On your phone, dial *#*#4636#*#* ...then select "Phone Information"
In this menu, you can change and set several things, including which band you use. This is on EVERY android phone, regardless of the ROM. You change these settings at your own risk.

Don't return it cause of that..! I've already got the 1900/850(wcdma/gsm) toggle in my sense rom, I just haven't included it yet cause I'm working on a 3g/edge toggle as well, and wanted to have both together, but since people want that wcdma/gsm toggle now ill finish it up 100% this weekend hopefully, update my rom with it and post just that by itself so people on other roms can use it as well.
850MHz has WCDMA as well... Setting it to WCDMA/GSM is irrelevant, as you can be on 850 and still on WCDMA.
You have to be able to specify the 1900MHz or 850MHz bands themselves if that is all you want; rather than the auto-switching the phones are supposed to do.

That is exactly what I want. I want to force the 1900 band only. On my Captivate, the only way to do this was to force WCDMA 1900 OR GSM 1900, there was no way to have GSM AND WCDMA 1900 because of how Samsung set up the frequency manager.
I'll try the *#*#4636#*#* mentioned earlier.
The phone doesn't respond to anything I set in *#*#4636#*#* - it automatically reverts back to HSDPA.
I also figured out my problem. Using OpenSignal, I did a tower map. As I thought, I have too many towers. There is one tower that is literally at the top of my block that gives me the worst signal and there are two other towers it connects to - one of them is about 4 blocks away from the other tower and gives me an okay signal and the other one is about a mile away and that gives me the best signal but it doesn't stay locked to any specific tower. Even sitting in the exact same spot, it keeps jumping around.
Oh and you can only select "USA bands", not individual bands from that menu as well
I can only use edge(gsm) 850 band in my office, rest of them don't work.
I used to select it very easily on my captivate using the *#2263#, but there is no such thing on Inspire 4G. Is there anyway to do the same on Inspire 4g??

On inspire *#2263# doesn't work. I tried *#*#4636#*#* as well. If i try to change bands it again defaults back to WCDMA. I can never switch to GSM bands.
If you live in a major area then its not uncommon to have up to 12 monitored cell sites capable of serving your phone.
I have both bands as well, and here is some info that may be of interest:
In areas that have both, there is a rather seemingly obscure pecking order:
Havoc is caused due to this:
Phone has every band available to it. Great! or, not really.
Here is the election process:
Tower sends out its info on the 850 wcdma carrier announcing as primary.
Tower sends out its SAME info on the 1900 wcdma carrier as secondary.
GSM primary is 1900 for association, 850 for data / voice with roll back to 1900.
The phone sends a limited amount of data to the towers when it hooks up, and in this data is the list of "Ranked" cell site ID's. (WCDMA ONLY, forget GSM for now)
The tower then is aware of what other sites can serve you should it become to busy. Using this and various factors, it will decide to either keep you on sector X primary, bump you to secondary carrier, or dump you completely. If it dumps you completely it is a forced hand off and not a graceful one, and you drop signal completely momentarily and then gain it back, but connect to a different cell id. However, that NEW cell ID only hears you at -104, useable but weak, and has 300 other phones it hears at -80 or better.. It has to pick some one to drop, and it picks you. Start the cycle all over again.
Disabling the 850 band stops this, because 1900 goes far shorter of a range and has far less people using it typically.. therefore the stronger site doesnt drop you because your phone reports no where to go. It also (in the case of the captivate) does not respond to requests to switch to GSM, as it will report no gsm availability when in forced wcdma mode.
Fundamentally, this is a misconfiguration on AT&T's part, since this little scenario shouldnt happen with proper sector alignment and tilting.
You did mention that you are in colorado, and AT&T has absolutely NO idea how to deal with radio towers and mountains. They seem to forget that not the entire world is flat.
If it is an option, I'd recommend a switch to Verizon, as it is unlikely this particular problem will ever go away.
Also, as to a Micro-Cell, know going in that those little buggers get the lowest possible priority.. meaning that if your phone can hear a real tower, its going to use that first. You'll have to fight it to get it on the m-cell.
Also, all Micro-Cell's are WCDMA 850 only, with no GSM or WCDMA 1900.
They also do not use HSPA, but instead use older UMTS technology (Who really cares at this point, if you are in range of a M-Cell you can use wifi.)
Other option: Disable 3G for the area you would use the M-Cell.
GSM shouldnt give the same problem WCDMA gives. The entire election process is completely different, and frankly works better than the WCDMA deployment AT&T used.
EDIT:
Wow sorry I didnt read the dates else I would have known this thread was a corpse. Found it looking for a WCDMA 1900 inspire lock option.
is there anyway to fix the 3g network band for nexus s,
in galaxy s i9000 i was using *#2263# to change the freq. band...anyone know any code or any app to check or to modify the frequency band?
or any radio support 900 HSPA?
my phone is i9020t
You can't change the frequency bands your phone uses via software. The only way to do it, is buy a broken phone, and use that phones guts (insides) in your device. Pending of course that the broken phone uses the frequency that you need.
Btw, wrong section. This should be in the q&a
Or some mad solder skills.
Not sure if it supports the 900Mhz band though.

*#*#4636#*#* you can set your radio to 2G+3G, 2G and 3G (with preference). You can set your bands based on your geographical location. See for yourself. I think the AWS nexus S supports 900/1700/2100 doesn't it?

Moved to proper forum, please post in the correct forums.
Seeing if anyone knows how to change the frequency to 1700 I'm trying to get at least 3g on my hox with tmobile, I can dial *#2263# on my note to switch frequencies but on the hox the code doesn't work I already flashed the One S radio update signal is better but edge is the only data I can pick up also tried all preferred network types by dialing *#*#4636#*#* still no dice, and selecting radio band from the testing menu only shows USA and Automatic normally I can figure out my problems on my own but I'm stumped on this one.

Not possible at the moment. Maybe after kernel source is released, but probably going to need s-off.

The 1700/2100 MHz (AWS) band is not even confirmed to be supported in hardware, AFAIK. It was just assumed from various inconsistent sources to be included in the specs.
If the hardware support is present, its not supported in software. There would be a bunch of happy people here if it were! Some have speculated that it can be enabled after S-Off. But this is purely speculation at this point.
This has been thoroughly discussed in other threads. Just search or browse around for threads discussing T-Mobile compatibility.
Yea I'm going to poke around the framework and see what I can find

Wow, that's brave.
I do not know if this is allowed and if it is not sorry but it is not a best of thread. I have been having trouble getting good speeds since the switch and have tried numerous combinations but get crappy speeds like .11 mbs down and .12 up
I was wondering what works for you and what speeds are you getting.
Like I said this is by no means a best of thread I just thought this would help others like me who are having trouble getting good speeds on our phones.
Any downloads to the radios not listed in the radios thread would be appreciated.
And if this thread is off limits I am sorry. Just thought I would help us newbies out!!!!!!
Thank you

What gives me a little pause here is that those settings and radio combinations will yield different results based on where you are located. Do you know anyone in your area with an HSPA+ phone who can run speed tests to compare your speeds against? It could just be that you're in an area with bad backhaul.
two important bits of info are missing what network type is your phone connected with (g e 3g h h+), and what radio are you using?

Baseband version is unknown
A good first step is to find some friend with a good t mobile hasp+ phone (like galaxy s2 T-Mobile or galaxy nexus for instance) ...See what speeds they're getting on T-Mobile data...If they're not getting good speeds on their phones, you'll never get good speeds obviously...Remember you're using a phone which was made to be used with AT&T....And from my observation most of those who use the SR with T-Mobile they get similar issues like the ones you're describing , t-mobile switched to the 1900mhz spectrum in some areas that would probably help a little, but obviously that's not something that you can do anything about...
If you really need tmobile service, it's best to trade your SR with a tmobile galaxy s2 , at least that I would do if I was in your situation,I don't like buggy phones or services...

It's a long thread but covers this issue pretty well. As far as I can tell there is no hardware-based reason a Skyrocket can't work on Tmobile as well as a dedicated tmobile S2.
I have been using a skyrocket on tmobile for a few months. I couldn't get better than 2G speed until I flashed a new radio and twiddled the apn settings. I get pretty consistent 4G now.
This is what I get using T769UVLH5 radio from this thread http://forum.xda-developers.com/showthread.php?t=1895400
Be sure to thank him:good:
I know you're getting different answers here but if you took an at & t skyrocket it means you have bands 850/1900Mhz for 3g ( don't even think about 4g lte at this point) while tmobl works on 900/1700/2100 3g bands. This means your phone is physically not capable of locking on those bands because it doesn't have them. All it's probably doing is sticking to the old EDGE network since it is a quad band edge.
Sorry to be the bearer of bad news

I do not believe that is the case. The skyrocket radio software limits the available bands. Loading a tmobile radio enables the required frequencies.
i727 freq's:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
4G Network LTE 700 MHz Class 17 / 1700 / 2100
Frequecy Source: GSMARENA
i727 freq's:
2G Network GSM 850 / 900 / 1800 / 1900

From what I've gathered the skyrocket has the same radios as the Hercules, it just has the added lte hardware. I am on 4.2.2 slim using the le1 radio. Still get random no signal dropouts but not as bad as the others. Think my ril and csc files are wrong so it looks like I have to flash a stock ROM to get them back. Anyone using a stock Hercules ROM?

I don't think our channel can do dual channel h+ where the T989 can.
for the others our phone has a penta-band radio it is physically cappable of talking to t-mobile on it's 3g,h,h+ networks just not with the att or rogers radios.
I want to figure this out once and for all.
What services does this phone support on the 850 MHz band?
The big question is whether UMTS/HSPA works. NYC area has amazing 850 band coverage on AT&T.
If I were to put a prepaid AT&T SIM in my phone, set my phone to only operate on the 850 MHz band, and set the proper APNs (necessary for 3G?); would I be able to get data beyond EDGE?
Only one way to find out...
There's no mystery to it if you read through the [GUIDE] Set up Verizon Galaxy S3 as World GSM Phone (confirmed working) thread and the [BOUNTY] ($205 so far) Enable HSPA+ on 1900 MHz / 1700MHz for VZW Galaxy S3 i535 threads completely....
With the radio software verizon has on the phone, the galaxy s3 is quad band GSM (850/900/1800/1900) and single band WCDMA (2100).
We don't know if it has the hardware for WCDMA 850/900/1900 and until now, nobody has successfully flashed a different radio due to the bootloader lock. Keep an eye on the "enable WCDMA 1700/1900" thread for updates.
And just to answer another question that you might have, when my S3 was rooted and set up to work in Germany, I tried both T-Mobile and AT&T sim cards here in town. The problem with the S3 is that even if you try to select a different WCDMA band in the field test menu, the radio firmware will not allow you to change it from 2100. So in an area with T-Mobile PCS (1900) and AT&T PCS/CELLULAR (1900/850) WCDMA, each test I tried only ran on EDGE.

The first step is to experiment with different radio files, as one user in the 1700/1900 thread wants to do, but we need to get the secure-boot/bootloader unlocked so those files can be written.
Phones like the Rezound had the hardware for Quad-band WCDMA (3g), but took a radio file flash to make it work. The reason there is a bounty is because we -think- the Verizon S3 has the hardware, it will just take some work to get the software on the phone to talk to that hardware.
I know. I've been following the thread.
Was a little unsure of the details regarding frequencies.
As far as I understand, they're at a dead end. They need JTAG/UART to continue without worrying about bricks.

Yeah, and sadly, I lack the skills and the bounty probably isn't enough to attract a dev with JTAG and a phone to fiddle with to solve our issue
Verizon cdma is ran by nortel dual urban base stations the frequencies are 810-910 and 1840-2000mhz. The LTE is 690-760mhz 1x means that your on 850. 3g means your on 1900 or 850 depending on how far away from the site you are, and 4g means your on LTE. The LTE base station is ericsson but speeds will vary depending on whether or not the site is on fiber or T1 transport. Normally they keep the pre pay customers on the nortel dual urban... Oh by the way we are starting to decommission the lucent cdma on metro pcs sites and convert them to t-mobile GSM but luckily metro uses ericsson for LTE too so there's hope.
