[Q] cant get tmobile radios to work

I tried installing the T-Mobile VK1 and Kid radios on my ATT Skyrocket with no luck. I cleared regular and delvik cache, and tried again. It doesn't give data service. When clicking on Mobile Networks under settings, it says Insert SIM card. Any ideas? Running Sky-ICS RC7.4 Stock
The baseband says T898UVKID rightnow, which is as I would expect since my last attempt was the Kid radio. I tried posting this in the radio thread in the development section, but I don't have enough posts.
Just for additional info, I am an ATT subscriber, and when I flash back to UCLA radio, all is fine. Maybe I don't understand the purpose of flashing a t989 radio. My reception sucks, and I wanted to pull off the T-Mobile tower instead of att, is this wrong method or am I just being ignorant? Voice worked fine with the vk1 and Kid radio's, just no data??
Thanks

You will never be able to pull off the T-Mobile tower, even though you are using a TMO radio, you are connecting to the nearest 2G (maybe 3G) AT&T tower. Only TMO subscribers can connect to a TMO tower.

Thanks for letting me know.
I was hoping it would work, but it doesn't suprise me that it wouldn't, since I have an ATT sim card not tmobile

How horrible is your signal? I have read of instances where users have gotten a free micro-cell tower. I don't even know if they offer them any more but there was a period of time where people were getting them for free and just complaining to AT&T.

SGS 4g wont stay on 3g

i have an unlocked Tmobile SGS 4g and the firs ttime i put my ATT sim card in it stayed on 3G for about 10 minutes then went to EDGE and has since stayed there. I know the phoine can connect to ATT 3G but is there something i have to change to get it to stay on 3g?

I wonder if you need to put an AT&T APN in place? If so, check out http://developer.att.com/developer/forward.jsp?passedItemId=1700008.

+1. Wouldn't be a bad idea.

No SIM Card

Hey everyone, I am a Galaxy Nexus user but my brother got an old Roger's S2 LTE that he wants to put on a non-Rogers network (same one I am on with my GNex). However we are having a weird issue where if we insert the original (deactivated) SIM that came with the phone it detects it. But if we put in either mine or his own it just always says "No SIM Card". I even have a pay as you go AT&T SIM that wont work in it either. So far I have flashed CyanogenMod and tried the UCLF6 radio as well as the Rogers ICS Radio UXLF3 from this thread http://forum.xda-developers.com/showthread.php?t=1754473
I should note that when my brother originally inserted his SIM he got the unlock screen and paid to unlock it through cellunlocker.net and it was recognizing his SIM at that point. Since then however we have had no luck. He even replaced the SIM card board with a new one.
Any ideas? I am leaning towards hardware issue but its odd that it still reads the original inserted SIM

did you try to go back to stock firmware and see what happened

Yep. I'm pretty sure its hardware. I got it to read again but still no signal. I have it reading my AT&T card now but again still no signal.
In fact even without a SIM card in if I search for Network Operators nothing comes up. If I do the same on my GNex I get a listing so its looking like this phone is no good
EDIT: Just realized who responded. Your threads were VERY helpful for me! Thanks so much... I'm still not convinced the phone is toast... I have a friend with a GNex on Rogers (I'm on MTS) so I will see if I can borrow his SIM and see what happens

agree, not the phone, the only way to make sure of anything is to restore to stock and do all the testing from that point on
edit: dah, its the radio, what freq is the new sim card on that wont work, is it the same as T-Mobile
edit: maybe not radio, think its like rogers, could be network settings

Actually both MTS and Rogers use the same towers so the phone should be set properly.
I've got it reading my MTS SIM now but cant pick up any networks. Its set to LTE/HSPA/GSM (Auto) and MTS is HSPA.
Is there anything that could be done to the IMEI of the phone to sort of "blacklist" it from working on any network?
Here is where I have tested from so far:
Stock before I did anything to the phone (Stock rogers GB)
CM9 Nightly
Stock Rogers ICS
SkyICS
I have also tried both the lastest AT&T Radio as well as the latest Rogers Radio. With my GNex both myself and my friend on Rogers use the same Radio (UGLC1).
At this point it seems either the radios arent working at all or the phone is blocked somehow
EDIT: Info on the MTS network... Found on the FAQ on their site:
Any unlocked devices (i.e. devices that are not tied to a specific carrier) will work with MTS SIM cards (on the MTS 4G network). However, carriers such as Rogers, Bell and Telus lock their devices to work with only their SIM cards and these devices will not work with a MTS SIM card. Similarly, MTS intends to lock our devices to our SIM cards. Therefore, our devices will not be usable on another carrier's network.
Please note that any unlocked device must support 4G North American Frequencies (850Mhz), older GSM devices will not function on our new 4G network. You can find out if your device is 4G compliant by reviewing the phone's settings.

UGLC1 never seen that radio for the skyrocket
edit: oh, for the gnex
did you try the *#2263# menu

Yes when I try that menu (*#2263#) it doesnt do anything. I can do *#*#4636#*#* when on CM9 and it works but on stock and SkyICS it just FCs when I select "Phone Information"...
I am going back to Rogers Stock ICS right now. Gotta head off to my engagement party but will likely be back at it tomorrow

shouldn't forceclose, redl and try reflashing x2 the rogers radio, wipe/format x3 in cwm b4 going back to stock ics

Will do first thing tomorrow (or tonight if I'm still in any shape to do so )
If anyone reading this thread has a stock Rogers phone can you turn it off, take out your SIM and then boot it up without a SIM in it and then do a Network Search and see if anything comes up? On my GNex I get networks but on the S2 LTE I dont. In fact I have never seen any signal from any network on this phone yet with an MTS, AT&T and an old Rogers SIM
EDIT: Actually you will probably have to be on CM9. With stock you cant get to the Network Operator section without a SIM card inserted but in CM9 you can

Ok I had enough time to do as you suggested above. Wiped like crazy then went back to stock using the ODIN method and the firmware from sammobile.
Actually I figured it out... it only FCs when I have the AT&T SIM card in and I think thats because AT&T is RAT Locked? If I have no SIM in I can get to all the menus.

k, try to set the freq(play around with it) in that menu w/out sim, then shutdown and install sim b4 restarting, left haptic to click "end" is saving

Got home and went right to work. Almost positive the problem is the radio not working now. I managed to get both SIMs reading without issue but neither will get signal of any sort (even straight after stock reflash). Gonna call it for now until I get a hold of my buddys Rogers SIM.
Thanks so much for all the help, I really appreciate it!

[Q] Rogers SkyRocket No Sim Help

After much research, and scouring this forum (which Id like to note is fantastic) - i am hitting a brick wall and at my wits end with my Doctors phone. (Doing him a favor)
Here's the preface. He purchased (off ebay) a "presumed" unlocked Rogers Galaxy S2 SGH-i727, and wishes to use his existing Straight Talk Sim card with it. The Sim is confirmed working in his previous older Samsung cell, which i also have, without fail.
He gave the GS2 to me claiming it wouldn't read the Sim, and i thought, agh just needs a root and rom, and maybe some radio switching. And boy am I humbled. This thing will not read a Sim if its life depended on it. Before I rule out a beat phone hardware issue, id like to see if anyone else could just advise me of some things.
1 How would I confirm this phone is indeed unlocked from Rogers, and if it wasn't would that cause a no Sim read issue?
2 To make this go from work from Rogers to Straight Talk, is their a ROM, Kernel, Radio, Band known to do the job?
At this point I've used Sk8's CWTouch for Recovery and it works great, current ROM i tried is a TMobile one (Juggernaught 5.0), Stock Rogers/ATT Radio, and i believe the Rogers Kernel as well.
Any help on this mess i've gotten myself into would be sincerely appreciated. Many Thanks!

under the battery does it say "i727r", if no "r" at the end its not a rogers phone.
if there is a "r" try a rogers sim card and pure stock firmware .
if no "r" try a att sim card on stock firmware

yes, there is definitely an "r" making it a rogers phone, being in the US, i have no access to test a Rogers sim, but also this needing to work on straight talk is the mission, otherwise i believe he may have to pursue another route unfortunately thanks so much

bah does the thanks button disappear after you reply to someone? apologies

that was to check for a hardware failure for the sim card tray, you need to know before you can diagnose further, do a att stock restore then try a att sim card and see whay happens, nothing to lose

Vincom's suggestion is to rule out an actual hardware issue. On the other hand a non Rogers SIM should either work if it's unlocked or pop up the unlock dialog. Suggest trying an AT&T SIM since that's the closest to a Rogers. I have no idea about Straight Talk.

[Q] S3 HELP!!!

Ok all I'm a newbie here so don't hate on me please.
My problem is that I cannot receive MMS and have no data other than WIFI??
I just rooted a Galaxy S3 (Verizon) SCH-I535, 4.1.2, Build#JZ054K.I535VRBMA2.
I set up the phone GSM/UMTS and am using an AT&T sim card from my old phone (HTC Inspire), the sim card that was in my inspire was on of the large kind that did not fit the Galaxy so the guy at Best Buy had a little stapler looking thing that actually cut it to the right size?? I don't know if that has anything to do with my problem or not? I don't think so since I CAN use the phone for calls and text messages, but you guys are the pro's. UPDATE: I did go to AT&T and get the proper sim card.
I used ODIN 307 and a file named-root66_VZW_I535VRBMA2_nowipe.tar.md5, to root the phone. I installed APN Manager Pro and Titanium Backup, both paid apps. I made APN Manager a system app in Titanium Backup just like I have read in other forums.
I have tried to use my old HTC settings for the APN and various others I have found online, including NET10 but nothing seems to work! I still can't receive MMS or network data??
If anyone can help me to figure this out I would greatly appreciate your help!
Thanks in advance!!

That's not gonna work...

You're attempting to use an AT&T sim card in a Verizon device. Setting the device to use GSM/UMTS instead of CDMA/LTE while using an AT&T sim card that has been modified to fit a Verizon slot still wont work... it's still a Verizon device. AT&T and Verizon may both use the same frequency bands of 850 MHz and 1900 MHz for 3G, and 700 MHz for LTE, but their commonality ends there. To my knowledge you can't get what you're trying to do here to work. Even if you could get it to work, it would likely not be an easy task.
If you want your Verizon SCH-I535 to work, you'll need to use a Verizon sim card with an active Verizon Wireless plan.
Sorry to be the bearer of bad news man... but its not gonna work.

Actually I did get it to work....somewhat. I downloaded the app HiAPN Global for the play store, made it a system app and viola! I now have data and MMS, HOWEVER it is not good by any means. All of my MMS come across as group messages and the data is EDGE at best.
I am wondering if I need to flash a new ROM and recovery....bootloader?? I'm kinda lost with all the information out there but cant seem to find my exact situation.

You will only get EDGE. i used to use at&t Sim in Verizon S3.
The way I got data to worm was flash CM10 stable FROM AT&T Version (i747) to the Verizon version (i535)
That doesn't mean ALL roms will work like that. You don't have to believe me that it worked as some people will say "You can't flash a att ROM on a Verizon phone".
Some Roms have MULTICARIER support. Try one of those. But again, you will not get any speeds faster than EDGE. Verizon has those bands locked for US carriers, but there unlocked for over seas. (Weird huh)
Edit: IM NOT TELLING YOU TO GO FLASH A AT&T SLECIFIC ROM. ALL IM SAYING IS I USED A AT&T VERSION OF CYANOGENMOD TO GET MY DATA WORKING.
