[Q] How to enable EDGE connectivity...

All right I've went through all the posts regarding this and none of the options seem to work. I have terrible 3G/4G signal where I live. How can I set the network!!??!! Tried the apps tried the *#*# stuff (all I get with that is "RAT selection restricted!" WTF is RAT?) I can't even make a phone call or send a simple text with the one bar of 3G/4G I get. I know most are probably against the merger but I will hopefully benefit from it cuz there is a T-Mo tower down the street from me. Anyhow please help. I'm rooted, stock AT&T, 2.2.1

It's only possible with Rogers-based ROMs (e.g. Infused v2.x)
It's not possible with the stock AT&T ROM or any derivatives, and causes all sorts of problems with CM7.
Hopefully AT&T's Gingerbread update will fix this.

Would I be able to flash the rogers rom on mine? My guess is no... but its worth asking.

Infused v2 is Rogers-based.

Entropy, I was able to force 2G with Infused 1.5.3 when I had it paired with the Rogers modem. I used the star code *#2263# and that allowed me to select a GSM only band.
Also, on current infused.v2 builds, I cannot force 2G as they're not using Rogers modem and I don't feel like flashing another modem and bricking it on these test builds.

Oh, thanks for the info - it's the modem and not the userland! Very useful to know.

Lost LTE

I have ICS-SUPERLITE-4.2 on Rogers and i totally lost LTE. I wrote in many existing threads and dev section and no one answered.
I lost LTE, even in areas of full reception, i dont have it, i used stock APN and LTE APN and still dont get it. I do get 4G.
Other on rogers running 4.2 have lte, just less reception so im guessing radio is not the problem. Any idea?

mhx did say he broke lte in 4.1 so maybe you got something from that. im flashing now and ill see how it goies

well im on 4.2 so its supposed to be fixed

I was having lte issues on 4.2 aswell

LTE works fine. Just make sure it says ltemobile.apn instead of rogers-core. If it still doesnt work then go int the phones menu *#2263# and select option 4. After that go back into the menu again and select 1 for automatic.

I've had to use the *#2263# option to get LTE on every ICS ROM I have tried so far, works great but sometimes I have had to redo it after the 2nd and 3rd reboot for it to take...
Another solution is after you flash an ICS ROM is to have patience , if you wait 5 minutes or so after flashing, before even touching\unlocking the screen, then most of the time everything settles in nicely on its own.

if ur using rogers with the ics leaks, there's several issues. Call id and lack of lte being one of them. This issue is present with all of them, it is an unstable leal after all. i believe lack of lte unless near a strong connection is due to uclca4 issues.

well after doing what i wrote 2 posts above, i have no issues with phone except for reboot/power off hang, i also get the occasional 2-3 second lag but its quite rare. Besides, im very haapy with rom, battery life is much better than GB

no lte after ics leak
I've the same issue with AT&T in Miami which has a strong LTE network. LTE worked great with GB. After installing the ICS leak all I get is HSPA:11. When I go into *#2263# it says RAT Selection option is restricted. Anyone have a solution?

Probably don't have the correct apn. apn needs to be set to pta in order to get lte.

Ditto - well actually I AM seeing LTE, but a drastically reduced data rates. Does not seem to matter what ROM, or Kernel or how many times I have re-flashed or re-flashed just the ICS Radio, I get roughly HALF of what I was seeing on GB. Ugh. I don't WANNA go back to Gingerbread. I just want perfection. Is that too much to ask for?

It's not the APN, at least in my case. It just crappy reception, and it happened exactly when I flashed ICS, and has been like that ever since. This in spite of re-flashing the Olin leak, reflashing the the radio, etc. It really irks me, and I do NOT want to go back to GB

RAT Selection option is restricted
Just flashed SeanZ ICS 4.2A-7 ROM and i727UCAL4 modem. I'm still getting "RAT Selection option is restricted". There is nothing else on that screen. This has been 3 different radios now and I cannot get a screen that allows me to select the radio band.
Would flashing a different kernel work? Any other ideas?

Still working on finding the right combination. Would love to drop Rogers for Wind with a mint second-hand Skyrocket I just picked up. Let me know if you have had any success.
Tried:
1) Juggernaut ROM/Faux009 kernel/Telus i898 KJ3 modem = not working
Juggernaut ROM/Faux009 kernel/T-mobile VK1 modem = not working
2) CM 9.1.0 ROM/Included kernel/Blaze modem MOD = barely working (was able to send one text while I was outside despite being well within coverage)
3) Stock ROM(ugh bloatware)/Stock kernel/Tmo i898 KID radio= best reception so far but still cuts out regularly
Testing in Thorold, near NIagara Falls

So far it's working pretty good in 416.
I am using the Rogers SkyRocket
Slimbean 4.1.2 It has to be a 4.1.2 ROM it seems for this to work with the radios/modems as they are compatible with 4.1.2 and below
It works great and I get to 20M on speed test.
**** This is my current issue and I will probably try a different ROM (I really like the Slim stuff)- I reflashed SLIM over the current Slim and will see if it starts the dropping of modem again.
This is my post from anther thread.
The modem keeps disappearing and I have to reflash it to get a signal again.
The phone will just lose the signal and rebooting etc, does not help it get back. You have to reflash the modem file again. This is very strange. I have never read any posts about this issue either.
carrier- Wind Mobile Canada - AWS network like T-Mobile.
It's Slim Rom 4.1.2 on a Skyrocket.
Modem is Blaze 4G LB7 (T-Mobile)
fourth up from the bottom
http://forum.xda-developers.com/show....php?t=1895400
Everything works great but this issue turned up about 2 days after flashing. I wiped and formatted everything before I flashed the ROM.

I chose this radio because T989 users were saying they got better signal on this than even on Blaze radios. Or something like that. I'd link it but I spent like 7 hours fighting with it, way past my normal bed time, so I hardly remember anything. Here is a screenshot of my phone running the radio to prove it isn't a brick-maker. I also do not know if this supports 3G/4G, because as you can see my tower is EDGE :/

I'm gonna test it here in Vegas as soon it's done charging and nandroid backup. Hopefully, you get 3g/faux-g soon.
Yep can confirm that this radio works with faux-g here in Vegas. It's a little slow right now in the part of town where I'm living but workable. To the OP, radios are important for the type of ROM you want to be using. For example, a GB ROM depends on a GB radio and the same goes for ICS/JB ROMS.

I'd be content with reliable 2G. According to mapping apps there is a whole 1 tower here, 2G, and barely usable. Many times it will show 1 bar and still say 'Emergency Calls Only' >.>
I flashed a T989 ROM to enable Wifi Calling, but I need a new SIM card from T-Mobile (a 'GBA SIM'). It took a while with a bunch of phone tag across T-Mo departments, but I think I finally have a 'GBA SIM' coming at the cost of $0.99. Will report.

My phone reports that the mobile network type is "EDGE:2". I've assumed that this means I am not in a 3G area. The T-Mo coverage map shows the majority of my area as 2G. There is one small light green spot (assumingly 3g?) over my house, but I think this is just an error on the map. Therefore I am unable to properly test for 3G/4G connectivity.
I've also asked T-Mo if there was any plans to upgrade our tower to 3G, and unlike AT&T who would quickly counter with "but we have 3G in your area!", T-Mo sent me to some activist page to start a local rally to convince local officials to upgrade coverage. I guess this is their way of admitting it is, in fact, a 2g tower.
I've also changed my radio back to T989. I'm not sure if it was a radio issue or what but it seems after a few hours the phone would lose service completely. I'm still testing stuff.

What is the average signal strength that you usually get? Also , if I read correctly, you are now using the stock t989 radio on the skyrocket? Which would mean GB?

this radio (UVLH1, 4.0.4 ICS latest T989 radio) is also doing the same thing as the note radio. After a while (3-5 hours) the status bar will show service (2-3 bars, even fluctuate) but the system is "Searching" and calls and txts are missed. Need a stable radio...
edit 2: I guess technically I could just ust the original AT&T radio since I only get 2G here anyway, and T-Mobile is re-farming so 3G will eventually work on 1900mhz., the 1700/2100 is going to LTE like it should, thus our skyrockets on AT&T radio should technically be able to get T-Mobile 4G LTE when its available
edit 3: rogers (I727TR) radio probably better than AT&T for the sake of rat unlocked
edit 4: removed edit 1, just gonna use I727R UCLD2

OK. Sorry that the radios didn't really work out. I do encounter some network disconnects here but not a total dealbreaker. I guess we'll have to wait for T-Mobile. On a sidenote, I am finding I have better coverage with this radio.

I do like T-Mobile but I will watch from StraightTalk (AT&T Sim) and try again when they grow some more here. I need mobile data to work. I wouldn't mind 30kB/s but I only accomplished that once. Heck I'd even take 5kB/s if it didn't take over 2 minutes to establish one connection. I can't even use MMS most the time because it seems to require 4+ (-90) bars of service before EDGE will even establish a connection.
Edit: Got my 'GBA SIM' today for Wifi Calling. Works great on this ROM combo. I just wish I had mobile internet. I may do some tests as I am secretly hoping this GBA SIM has 3G/4G and maybe my old SIM was a 2G sim.
For archival reference in case I go back to AT&T ROMs, and my sig changes, Wifi calling for T-Mobile works on our Skyrockets using Faux123 ICS T989 Kernel for I727 MOD v001 and SGH-T989 UVLE1 Infamous Resurrection ROM

Buy a Samsung Galaxy Nexus from the Google Playstore for only 349.00. Its unlocked and works with both ATT and TMobile 4G.
That's what I did for my wife and using a Flashed Skyrocket on T-Moile 4G has been flaky at best.

No LTE with Custom Roms?

I know the skyrocket I727 supports LTE. With stock firmware LTE is not a problem. But when I put any custom ROM it no longer goes to LTE. Is this normal or is their a separate download for an LTE radio in these custom ROMS?

This is not common at all. Check that your apn settings are correct. And you have the recommended radio. What rom are you using?

I have tried slimbean superlite and a few others. My radio is well I can't seem to find that. My baseband version is i727ucll3 I use CWM touch...When I go into mobile networks is says HSPA:10 and that's it.

Radio or modern is the same thing as baseband. I'm not familiar with the slim bean rom so maybe someone who is can give you a better answer. But in Mobil networks, apn on the superlite rom I have three options with one being lte.

If you're using a rom like PA, CM10, AOKP and probably Slim Bean too.. 4G=LTE.

Have you run a speed test lately? As said, many custom ROMs don't have an LTE icon; 4G is LTE, H+ is what AT&T considers "4G" in areas without LTE coverage. Running a speed test is an easy way to tell. If you're getting LTE speeds when your phone says 4G, you're on a ROM that doesn't show an LTE icon.

Have you tried opening dialer up, entering *#*#4636#*#*
Go to phone information, scroll down to a drop down menu. Sometimes it'll say WCDMA preferred. Open it and select LTE and your signal should drop and cone back as LTE. After select LTE/GSM and close it.

Are you sure you were on LTE in the first place? AT&T is kinda misleading with their branding and calls HSPA+ "4G" whereas LTE is "4G LTE".
