unlocked on at&t no 3g

I tried to get the $15 (200 meg) data package to work, but there is no signal showing up on the phone. anyone got any ideas?

Yeah. I have really good idea....... at&t sucks

They use different freqs for the different companies 3g in the states, at&t uses the "standard" freqs and tmob uses its own due to fcc regs. They may also use different flavors of 3g also(ie UMTS, HSPDA, wcdma) the acronyms are endless...

Any ATT data plan should work, but only with ATT's 2G service*.
there are a few things I could think of that could be causing your problem which are separated by phone or network problems (these are all assuming your phone is searching for signal and isn't giving you any obvious errors about the sim):
PHONE PROBLEMS
1. Your MT slide is locked to WCDMA only, which won't work on ATT (see explanation below*).
2. Your unlock method didn't work.
3. Any other random prob with your handset hardware/software.
NETWORK PROBLEMS
1. You are not in a ATT 2G coverage area
3. You are in a location that the ATT 2G signal is being blocked.
2. There is an ATT network outage in your area.
The quickest way to narrow down your prob is to get a hold of an ATT phone that is working (either from a friend or an ATT store) and test your sim in that phone. that will tell you if you need to start troubleshooting your phone or your sim/att service.
*ATT uses a different frequency for their 3G coverage (ATT uses 1900 mhz and 850 mhz WCDMA as oppose to T-Mobiles 1700 mhz WCDMA). this means that if you locked your phone to WCDMA on the slide, then it is going to try to look for an ATT signal at 1700 mhz, which does not exist. Unfortunately there is no way to "re-tune" the radio hardware in most devices to operate on a different frequency, so your probably stuck with 2G only if you continue to use ATT.
the only exception that I know of is the blackberry bold 9700, in which the radio hardware actually supports all gsm/wcdma bands, and just has the "Carrier appropriate" bands enabled in the software. this may be the case with the MT slide, but I doubt it.

UMM before any of that I'M GUESSING YOU HAVE THE PROPER AT&T APN SETTINGS?? Correct?? .. if not, you need to find the att apn address and replace the stock epc address

No clue research it Im sure its simple to find ATT APN address ..our stock tmobile one is epc.tmobile.com

The apn definately must be correct to use data once the phone finds signal and connects to ATT's network, but jeffbichel said his problem is that the phone isnt getting any signal to begin with. the apn only comes into play once your phone has already found and connected to a cell tower.

I read elsewhere that the only way to get a Slide working with 3G on AT&T is to order one destined for Roger's telecom Canada since they use the same 3g frequencies as AT&T...

You can use a TMO phone on AT&T, the 3G will not work, EDGE only. On an Android phone the APN settings must be set correctly for AT&T for the data to work.

Airtel 3G APN Settings

I filled in the new settings in APN but im getting 2G instead of 3G ?
Anyone knows what i did wrong ? And the airtel "customer help" are not exactly helping me in any way.

For Airtel mobile office your settings are ok just remove proxy and port. if you are trying to setup airtel live then apn should be airtelfun.com and proxy and port remains. most of the android phone will not display 3G instead it will show H for HSPDA. if 3G signal is weak it will switch back to edge and will show "E". try changing the mode to WCDMA only. then check.

as an alternate give these a try for data.
1. Homepage – any page you want to set.
2. User Name – Blank
3. Password – Blank
4. Proxy – Enabled/yes.
5. Proxy and Server Adress – 202.56.231.117
6. Proxy and Server Port – 8080
7. Data bearer – GPRS or Packet Data.
8. Access Point Name – airtelgprs.com
9. Authentication Type – Normal
10. Use preferred access point – No

Even I am having the same problem. My settings are correct as stated above but I am getting only 2G. 3G hasnt come up even once and I have travelled over 20 Kms across the length of Bombay, so coverage cannot be an issue. Do I need to change anything else?

Open Dialer and type this *#*#4636#*#*
Select the drop-down that says "Phone Information". From there, scroll down to where it should say "WCDMA preferred", and change it to "WCDMA only". Use the back key to get out. now check if your phone is able to detect 3G network. once it connects to 3G and you see H.
Airtel has worst network in mumbai so for phone to stay connected on 3G network signal strenght should be above -125db or else phone will switch back to 2G network. may be because of low signal stength you are not able to get 3G

Hey Smokin,
I tried this method to force WCDMA mode on my Samsung Captivate, but had no luck getting the 3g symbol on my phone. Instead I still have the E symbol for edge.
I have been trying since Saturday to get Airtel to put their 3g service on my phone, but had no luck. I went to a Airtel shop yesterday here in Manipal to get 3g manually activated on my phone. That didn't do any good as well.
I believe like you said that the problem isn't the activation aspect of 3g, but rather the signal strength for 3g is too low to be picked up by android phones. When I went to the Airtel shop the other day I noticed that most of the people there with working 3g phones had either a blackberry or iphone device.
If this is actually the case, I have no choice but to switch to another cell phone service provider who provides 3g service with a "android-friendly" signal strength. Is there such a thing?

Can you try with any of 3g enabled handset to see if you get 3g network in Nokia phones like n95 it should Show 3.5g. Also was your phone able to see Airtel network in wcdma only mode.

Hey,
I don't have any other handset with 3g capability nor do my buddies here. When I put the phone in WCDMA mode, I didn't get a signal for the GSM Airtel Network.
Apparently other Galaxy S owners have been having problems with Airtel's 3g network (Read at the comment section below: mobilegyaan.com/airtel-3g-karnataka-price).
Maybe Airtel will resolve this soon?
Edit: 3g is working now on my handset with Airtel network in Manipal.

Airtel launched its 3g service in Hyderabad today. And I was facing similar problems as others here. Selecting "WCDMA Only" did the trick for me and now I have the 'H' symbol on my HTC Wildfire.
However, I checked the signal strength and it is displaying -81dBm 16 asu. Does this mean I won't be able to access 3g with "WCDMA preferred" selected as I often roam and would like to fall back on 2g in the absence of 3g signal.
Also, will the above mentioned signal strength affect the call quality in any way?
Thanks for your help..

-81dBm is greater than -124dBm it is a good signal strength. problem with WCDMA only mode is if there is no 3G signal there will be no service. best would be to keep on on WCDMA prefered.

hey smokin i have nexus s....airtel....my phone shows 3g symbol but i get only 2g speed...i did as u said....initially it was selected to gsm/cdma auto(prl) and i changed it to WCDMA only...still no change....signal strength is -83db...can u help here?

Not to sound like a completely dumb guy, but I have a Nexus One and resolved my issue by texting "3G" to 121 on Airtel. That activated 3G service and with the APN settings above, I started getting HSDPA speeds.
Hope that helps someone. Took me an hour to find that part....

So i activated 3g n put a 3g pack...
Galaxy fit..... But this goddamn Airtel gives me like 15kb/s in new Bombay....... Calling those jerks CC Temme some Bull**** that Airtel operating 3g In Maharashtra on Vodafone and Idea networks... Tells me to manually select Vodafone or idea network! (absurd! Airtel Sim registered on Vodafone network )
So i try that also... Speed 20kb/s...
Bharti mittal should resign!!
Get a Vodafone Sim... I get like 4.84mbps on cell which is terrific!!

ATT now giving me HSPA+ in Atlanta?

I came from my skyrocket that had LTE so im still on the LTE plan.
i copied my APN settings from the sky rocket to the N4 and have been enjoying the slow measly 4-5mb download on GOOD days but averaging 1-3mb most days.
i have the older radio AND can enable the LTE setting and have it stick but dont need it as im currently on WCDMA preferred.
my phone status shows HSPA+ ATT when it usd to show just HSPA:10 or :15 etc what ever number it shows at the time.
now i'm getting consistent speed tests over 14mb down and 1mb up
I'm currently in the Lawrenceville/Duluth Area of Georgia if that helps
I have enclosed some screen shots.
anyone else noticing this?
its really nice to have these speeds now.

You should block out your phone number on the first screenshot lol.

HSPA:15 is H+
I'm curious to see what your APN settings are now. Noticed any obvious differences in original/default APN?

Im not even using the LTE radio lol
i just saw an email at my company that said this:
Dear all,
I know that it's been a long time coming, but hopefully you all have already experienced, and felt, the new in building wireless solution that AT&T has deployed for us. As part of the contract renewal that we did a few months ago we negotiated with AT&T to deploy, at their cost, a new in-building cell system to solve our cell phone coverage challenges. This system went fully live earlier this week, and we now have across buildings A and B full 3G, 4G and LTE coverage for AT&T with a state of the art system.
I hope that all of you enjoy the new system and extended coverage!
Thank you!

so it looks like that AT&T came out and deployed a new tower that gives us full range of coverage including 3G, 4G and LTE
since i'm NOT using LTE an band right now and on 4G that means that AT&Ts NEW towers have the capability of HSPA+ since we are using it right now but its just not deployed everywhere yet.
im spoiled now and wont want to go back home to my normal AT&T tower

Requesting AT&T APN Settings for Galaxy S4

Hey Everyone,
I need the AT&T APN Settings for the Galaxy S4. I flashed to Foxhound Rom(I9505 rom) and flashed a AT&T Kernel but now my data speeds are all out of whack.
Here's the settings I've tried so far http://rootzwiki.com/topic/31135-att-apns-for-custom-roms/, but it's still too slow on the speedtest app compared to what I was getting before.
Also I noticed after using the above settings, my "Network Mode" (found in the Mobile Network settings) keeps switching from what I set it to -- LTE/WCDMA/GSM (auto connect) -- automatically to WCDMA/GSM (auto connect).
Thanks in advance.
Regards,
Himalaya's Playa

Thanks for the speedy response Thermawolf. Currently I have all 5 APNs plugged in, and I'm still getting these speeds (3 down /.5 up) in an area where I was confirmed to have LTE. Should I only be using one APN?

Hmmmm I don't know what you mean by plugged in? The phone itself should acquire these APN's when it scans for networks. Make sure you are just using the ATT LTE apn it acquires and then go back and select GSM/LTE/CDMA or something like that and it should stick and hopefully fix your speed. Although your area might not have full LTE yet.

I had to manually enter new APNs into my phone. what I did just now was delete the other 2-3 APNs (Cingular, Cingular MMS) and now my speeds are back up to 20Mbps down, but my upload is at 4.5Mbps up. Is the upload speed normally that much lower?

That is an extremely low upload for LTE that's for sure. I would run a couple tests and see what happens. It could also be ROM related as I am running Task650 AOKP.
Also I updated my post with my APN settings.

what modem are you using? Also, I noticed you are sprint, is this for the same device?

Galaxy S4 - no LTE option?
I recently bought an unlocked unbranded Galaxy S4 GT-I9500. I let it (probably a bad judgement call) auto update via WIFI from 4.2 to 4.3 before it ever had a sim chip in it. I'm assuming not an ATT update, no branded bloatware. Root was easy with Odin. So...now on ATT, but not getting LTE? Added the APN settings shown above, but found no LTE listed in the Network mode options. No Network access when I select that APN either. WCDMA/GSM auto and single option for each only thing there.
Any ideas / suggestions?
Maybe I just need to find the right ROM, I like Cyanogenmod 11 kitkat, and get that on there and see what happens.

T-Mobile MMS Fix over 4G LTE

I have heard that people using the MT7-L09 version of the Ascend mate 7 are having issues sending MMS Messages over Cellular network and the only way you can make and receive them is over Wi-Fi. Well the issue is Really common on Internationally unlocked cellular phones and the issue is really simple to fix. The problem resides in the APN Settings. When you pop in your T-Mobile or AT&T SIM card, the device sometimes sets up a Automatic APN Set up within the device. Sometimes, when the device does this, it puts down incorrect or old values. Now to the fix.
GO into Settings. Under Wireless & Networks tap More, then tap Mobile Network, and then Access Point Names. Under general you will see a already preseted APN called T-MobileData and under MMS something called T-MobileMMS. If you click the "i" next to the T-MobileData APN you will see that there is nothing set under the MMSC. To add the MMSC value just tap the value and type in http://mms.msg.eng.t-mobile.com/mms/wapenc
After that tap OK then go down to APN Type and make sure default,supl,mms,hipri,dun is displayed. If not, add in the missing values. Make sure that mms is included in the APN Type or MMS Messaging will NOT work. Just for future proofing Make sure you APN Protocol is set to IPv4/IPv6 as set with the latest LTE phones.
Once done select OK and then Save at the bottom. Once done make sure to Select the APN Radio button you just edited a couple of times. You may see your Data connection go out and then show 3G/H/H+. This is normal as it is refreshing settings. Let your phone sit up 5 minutes or until 4G Shows up. Once it shows up, hop into the Messaging app and try sending a MMS message to yourself and you should be able to send and receive it without wifi over 4G LTE.
Those on AT&T, the same fix applies, but with your specific Carriers's APN Settings
Just to let you guys know and other friends, if you ever get on a AWS band (3G/H/H+) and you have NO data connection and your carrier is T-Mobile, this is because T-Mobile has shut down (Or will be shutting down and removing) all AWS band antennas from their towers to make room for new Cat. 6 Carrier Aggregation. So if you get the MT7-L10 version (which is the 3GB RAM Non-LTE version) the AWS bands probably won't work with it and you are stuck with using 2G EDGE as data. This goes for ANY phone that relies on one of Many AWS bands to get 4G Speed internet. For more info on this, check out http://www.tmonews.com/2015/06/aws-hspa-t-mobile-markets-shutdown-dates/
