I picked up a mytouch 4g Slide (not the MT4g) to play around with for myself but it gets no signal at all. There is an X. No bars.
Now I know on an older GSM phone with no SIM installed... it gets signal. I would guess for emergency calling. I DO NOT have a sim to test this phone with, but I was almost sure it should still show a signal. I have tried indoors and out where Tmo is pretty dominant in signal.
Wifi works, but does the internal antennae support both the wifi and phone? are they seperate antennas for both?
Does someone have one at their disposal to check this out for me? Should there show a signal with NO SIM?
I really dont wanna activate this without knowing if it works.
Everything is stock, rooted, 2.3.4. But was showing no signal even with stock/unrooted PG5?IMG redone over and over. The phone is S-ON/Unlocked (locked made no difference.)
Z-Device (device testing app) shows an X for ANT. Hence the antennae question, but like I said, WIFI works.
Thanks for your anticipated assistance.
No sim no bars, any phone I've owned has been this way
For the record I did not take out sim to test

First ever hearing of a device that does such. Every phone I've ever owned (quite a few, however all android) will not show that it is connected to a network without the sim card installed nor when it cannot read the sim that is in it.
I'm not calling you a liar, simply stating this is different from all my prior experience. You won't be showing any signal in the status bar but you should technically have access to 911 & emergency contacts if need be.
I am kinda new to the whole GSM thing, been working exclusively on CDMA for some time now, hence the question when I seen another GSM phone shown a signal. The only difference I noticed outside of the obvious, is that the phone showing a signal is network unlocked, where-as the MyTouch 4gs is not. Would that make any difference? Is each phone different?
Not that I know of, pretty much ever phone I have used is network/sim unlocked and I've always had the same result. I used to buy, fix up, and sell phones on eBay and I've gone through in the hundreds, nearly all I would sim unlock (and root if android etc) and to my recollection I always needed to put a sim in to test if service worked, without I could use WiFi no problem but no bars otherwise

Thanks for the input peeps, I will go ahead and activate anyways and check.
Again, thank you all for the fast responces.
You all was right, thanks, it works.

I've tried several resets, I even restored a two day old backup made via spb backup and yes, have also gone into "connection setup" under connections and let it setup AT&T as my provider which subsequently asks for restarting the pda. Also, the HSDPA utility is still showing a check mark on HSPDA On.
All of the above have failed to get my phone back to 3G speeds. I've even tried to surf/download thinking maybe just the icon is showing "G" or "E" however its painstakingly slow now.
So, its either the "G" icon or "E" is what shows now. This all happened when I looked at my phone this morning after SPB backup had performed its scheduled backup that was triggered around 2:30am.
other than that... THIS IS AN AMAZING ROM BY DUTTYTHROY!! YOU RULE DUDE..
oh.. almost forgot: my radio is 1.27.14.09 which I've read that only works with the AT&T Tilt, which is what I have. Just an FYI.
Someone please help as I'm a heavy data user hence can't afford to be without 3G/HSDPA ... TY

Please - somebody tell me this isn't true!!!

Cite your sources.
I get 3G/HSDPA just fine on my Kaiser, whenever at&t actually built out some towers.
When I first tried this rom (radio 1.27.14.09) I lost all connection with AT&T but after several hours and traveling into another area everything seemed to fall back in place. I've also noticed that the phone is very slow to reconnect after passing through blacked out areas, not sure why other AT&T phones lose connection but come back online much faster.
Otherwise the ROM is great.
Is it possibly something to do with your rate plan?
EDIT: nevermind I'm using a diff rom I think

I personally don't have any issues on the network. I'm running Dutty No.6 AT&T. Does this problem apply to a CID unlocked phone, a SIM unlocked phone, or both?

It shouldn't be my rate plan as I have the PDA unlimited for $39.99. Also, here's an update. This morning when I woke up my Tilt it was still showing E and my wishful thinking of Santa giving me a pre-christmas gift by fixing my phone (I'm easy) were just about drowned. ...however out of nowhere and without doing anything to the phone like soft-reset etc., the 3G icon came back and now its been coming back intermittently..
Now I'm pretty sure that its not that I'm traveling in a non-3G area and thats why its coming back intermittently as I live in a decent size metro area of Jacksonville FL and also because the areas I've been to this morning have always had 3G.. unless I'm wrong.. which I sure hope so..
BTW: I "downgraded" my Radio to 11.17 last night itself as one of the things I was trying to fix this issue. Just an FYI.
Here it is in a nutshell!!
Please note the following:
1) Got my new (unlocked) tytn II on dec 12.
*Sim in at 6:00pm. Had 3g & hsdpa till 10:00 pm. Went to bed.
*Dec 13th could not make calls or connect to data while on 3g.
*Calls would disconnect. Hsdpa message "the answering modem has disconnected "
* Switched back to gsm mode. Phone works but no 3g or hsdpa support.
*Dec 14 called att. Customer service said "unknown device" not supported.
*Transfer to data tech " Stated unsupported device" cant add the pda data package for $39.95. Stated my imei was blocked from 3g & hsdpa because of unlocked device status. But edge & gsm would work. Note edge & gsm modes work.
*Data tech said go to att store and get another branded att 3g device and use it to activate the pda data plan.
*I did this at 2:30 pm est. It worked for about 1/2 hour till 3:00 pm est. So much for my $39.95.
*Called att again & got a product support specialist(pr guy haha).he stated:
2) Att will not support an unlocked device.
*I said what about my $39.95???? I also said that i was a paying us att customer and was willing to pay for the high speed service. He said that they could no change my device unlocked status within the att network even though i was willing to pay for the data plan. I was pissed at that point. I told him that the hardware supports 3g & hsdpa and stated that att had locked a paying customer out of the 3g network. He said again "att does not support unlocked devices". I then asked him why i had access to the gsm & edge network and why att supported me on it and not 3g or hsdpa? I must have stumped him because he put me on hold. His reply after talking his boss was "att wil not support an unlocked device. We went back & forth like this until I Said "THIS IS BULLSHIP & HUNG UP.
* He call me back about an hour later because i threatened to switch back to verizon an stated " if you had the att original rom and if the phone was carrier locked it may change my device status" I said that I would give it a shot.
* Got the orig. att rom from here. Used sspl to apply cid per the reverting instructions. Phone said att 3g on startup & cid-8. Still no 3g. flashed hspl and bact to duttys rom 7.b for now.
In summary I can get the 3g & hsdpa signal but nothing works when connected! CAN YOU SAY CLASS ACTION LAW SUIT!!!
3G Test on AT&T network
How can we test if we are getting 3G speeds after changing our ROMs? I see the 3G and H logo's but don't think I'm getting the speeds.
Does changing the ROM unlock our AT&T phones?
Is there a ROM that is transparent to AT&T and allow us to use the 3G speeds?
Will reverting back to the AT&T Rom allow us to get the 3G speeds again?
newbie
Are you on drugs? , AT&T unlocks their phones, that does not matter , the reps you were speaking with are retarded they use a BILLING SYSTEM called TELEGENCE if you enter a IMEI wrong or of a unlocked device it gives back a UNKNOWN device message which means pretty much the reps can and if they dont want to , wont help you get your data working because they are lazy as ****. they do not block data on phones nor can they monitor your device to know what you are doing. their HLR's are only one way addressable.
Ok, I just upgraded to this ROM (cus duttys roms are amazing) after I read your post and...
I ran into some connection problems after my programs started looking for "my ISP" (isp.cingular) instead of "MEdia Net" (wap.cingular) In "advanced settings" in "connections" I re-set programs to run off MEdia Net, and it seems all is well
I think it might have switched when I was screwing with the comm manager and turned G3 off
DISCLAIMER: I'm a noob so take my advice with a grain of salt haha
No probs w/ ATT
My unlocked phone works just fine on the ATT network and i constantly get 3G UMTS and HSDPA speeds. Att does not block any device you are able to use on their network as they have roaming contracts with cell phone service providers across the world. If your device does not receive 3g speeds you can have your imei number added to the ATT allowed database just call 611 from your phone and talk to the service rep. If they give you any problem then call back and tell them you want to add the imei number of a wireless data card for computer and they will add that for you.
Must have been smoking the glass pipe!
Sorry folks.
This is a reception problem for me.
ATT really jerked me around.
The problem is a weak 3g signal.
If i dont have four bars 3g & hspda fail.
I went & sat under an att tower and everything works.
As soon as I drive away from the tower and the signal strength drops I loose 3g calling & Hsdpa.
Is there a fix.

Digg and random bloggers aren't really a good source. I remember the bullfrap article on Digg about Hummers being more environmentally conservative over a lifetime than any other green car.
have you tired having your sim card replaced? I had a similar issue where i was not able to call or receive calls in 3g but could on edge for a good day. Went to ATT and found out that others were having same issue with kraiser had them replace my sim card and everything worked great after.
Got 3G back and for good.... so far!

thanks for the tip jellorice.. I actually got my 3G back since yesterday and its been working great ever since. As for the sim being faulty, Thats something I didn't even think of and now that you've mentioned it, I'll keep in mind for future troubleshooting as I'm sure some other issue will crop up.
Nevertheless, Dutty's ROM 6 is UNBELIEVABLY AWESOME!!! I'm sure Dutty's gotten numb to all the kudos he's got and still is getting, being in Gazillions... but I wish I had better words to describe this ROM as for someone like me who is virtually bringing food on the table because of the Tilt (heavy business user), the key strengths of his ROM are just Marvelous.
Sry for getting sidetracked.. I got a little exited there.
My MyTouch 4G slide has been sitting for a month or two after previously working fine. Now it powers up however it can't get a signal with my T-mobile SIM (or my wife's). I'm concerned that somehow the radio might have gotten fried. So far I've reflashed it back to stock, unrooted, and hard reset it a few times, nothing has worked.
If I go into Wireless & Networks, drop down to Mobile Networks, Then Network Operators, and "Search Networks", it takes a few moments and finds AT&T & T-Mobile (I'm in an area where my devices normally get full T-Mobile service). However when I try to connect to T-Mobile, I get a message saying "Your SIM card does not allow a connection to this network". Same SIM works fine in a G2, connected to T-Mobile.
Anyone have a way to test the phone radio, or perhaps have an idea on what it's issue is?
I have had this exact problem, and attempted the same solutions, but without success. Was working fine, and then 1hr later quit working and was not able to repair even after return to stock/deroot, etc. Doing warranted return, and just got replacement phone by mail for swap out from t-mo.
am a little worried about reroot and rerom in case I have another problem.
My device is doing the same thing. Not sure when it started... I havent used the MT4GS in a few weeks, picked it up and reset it back to stock everything, and it's not getting any service from any of my SIM cards. I unlocked it a while ago to use on AT&T prepaid SIM, and not even that will work... Any advice would be helpful...

I've used Z-Device Test by Zausan Innovacion Tecnologica to test just about everything on my phone.
I'm having a similar issue on mine after trying jupoeanutbear and failing. I have signal but data craps out at random times now.

I picked up a mint verizon s3 local on a trade for some scrap phones I had. So here is my issue. I put in a sim(at&t) and got the switch to global notification but it never gets signal. Phone info shows -120dbm 99asu. Figured since it was free I would play with it and installed hyperdriver rls 16 still nothing. Took everything back to the first stock ics nothing. Currently have it on jb 4.1.1 nothing. I started to wonder if the radio was trashed so I dialed 911 with no sim in the phone and it popped up 3 bars and made the call.
Am I wrong in thinking this phone will work on US networks with a sim? Anyone ran into this problem possibly can maybe point me into a direction to get it working. The phone is clean and not blacklisted and it reads the different sims I have put in it I just can't get any signal to pull up other than an emergency call. I know there is signal my s4 is on the gsm network sitting right next to it.
Thanks in advance, I have been searching since yesterday for a solution.
****update.....Went ahead and took it to 4.1.2 stock and happened to find an old verizon sim. Phone picks up verizons network without issue. Still nothing when using the at&t sim.
It isn't working for AT&T because you haven't set up the appropriate APNs for that network. Google AT&T APNs. Reboot after making the changes. CHECK FOR TYPOS!

I thought I would at minimum show signal even without adding the apn. From everything I have read its talk ready just inserting the sim. Will look at adding apn's this morning.
Final update. Still no joy on getting it to work and I listed it for sale.
There's a thread about getting vzw s3 to work on T-Mobile, I'd imagine you'd need to follow a similar process. And FYI, all phones will call 911, sim, no sim service, no service, they'll call 911. My niece was playing with one of my sisters old, no longer connected phones. All of the sudden police and ambulances showed up. She had dialed 911, they tried to return the call unsuccessfully so they used the phones GPS info and showed up at the house.

I bought a house and moved.
No service in the house with Verizon.
So, I switched to AT&T.
AT&T told me I would get HSPA+ with my Verizon S3.
Well... I have 2G, voice, and text.
Anyone have an idea of how to get HSPA+ enabled? Is it possible?
I have a custom ROM, but I can flash anything if it would help.
I don't think it's possible, they run on completely different networks (CDMA Vs GSM) and the phones radios are built accordingly.

There is a way cant remember where i read it, maybe on the t-mobile forum. I recently bricked my att device and came across a verizon variant and was able to use it for att with out having it sim unlocked just a few hours ago steps taken were as follows:
After swapping the motherboards i factory reset the non rooted verizon device from the settings menu as I was just going to sell it on ebay. I had been using wifi only on a sim locked t-mobile device but the camera was not working so i switched back to the verizon and was prompted to complete the set up after i booted the device with no sim card inside. I got the no sim card message and ran the app Region Lock Away that has a red circle icon and a black unlocked pad lock by chainfire. I was skeptical 1 for the device not being rooted but tried anyway. The app said it was not able to verfiy root and closed; however once I inserted my att sim card without powering off the device i saw signal bars. Now Im not sure the app actually did anything and I might have tried the app before resetting it without success but after checking the network mode in the mobile networks tab it now shows Global as the preferred network. So i started texting people and then calling all with success. Now im still on the edge network and this may not solve your issue but I remember seeing the work around I think it has to do with correcting the APN settings but there is always a way to get things done. Keep looking you will find it. Im just happy to have cell service again but Ill be looking for the thread in a day or so as well.
Forced into an AT&T phone. It worked for 4 days then stopped. Their tech support claims the tap wasn't compatible and they don't know why it worked
I had 2g for those 4 days
I'm always on wifi but noticed my data wasn't working so not an ideal switch but if you are in a bind it does work. I'm still running at&t network on this Verizon motherboard just fine

Hello, I'm having a major problem with my phone and I'd be extremely grateful for any help or expertise.
PROBLEM:
I cannot get any kind of CDMA signal on TWO Verizon HTC M8 (I didn't post in that specific thread for a reason, I'll explain, please don't move it).
--------------------------------------------------------
HOW THIS HAPPENED:
The first phone, I was using as normal and it was fully functional.. One night i flashed a ROM and ended up falling asleep before if built the ART cache (so it was just playing the bootanimation) and the next morning I awoke to find the boot animation still running. The phone wasn't hot but ever since then I could never get any kind of CDMA service (so i can't use my carrier.)
The second one i just bought and put my sim in and BAM. Same problem.
--------------------------------------------------------
MORE DETAILS ON THE PROBLEM:
If i put my sim in, i can usually get 4G data but can NEVER get any lower bands. CDMA settings are greyed out in settings. This persists across ROMs and radio firmwares. My immediate thought was to get a new sim but my sim works absolutely fine in my LG G2. The sim is cut from a microsim but the point there is it worked fine before (and still works in my G2) and it didn't shift in the tray. I tried my friend's sim from an Iphone 5s and it did the same thing. I've tried everything i possibly know to do. This problem has basically cost me $400 dollars or 2 M8s.
Even if i go into the phone info hiddenmenu, i cannot select the CDMA or EvDo bands by themselves.
