Help Pls!Can`t connect to network

Hi,
I recently purchased an AT&T Tilt (HTC Tytn II) and unlocked it so that I can use it with the Rogers Network. It worked perfectly for about three weeks then I took it to Orlando for a vacation. While I was there, I change the network setting to manual and connect it to AT&T Roger so that I can use it as a roaming phone. When I got back to Canada, I changed the network detection back to automatic and it connected to Rogers for about 10 seconds then it lost the connection. So for about 10 seconds, it worked but only lasted 10 seconds. I also notice that when it connects it shows E (Edge) as a data connection. After 10 seconds, it changed to 3G. As soon as it changed to 3G, it loses the connection.
I wonder if anyone has this problem. I don`t know if this is because I used it on an AT&T roaming network. I`m very puzzled and any help is greatly appreciated. Thx!

I am having the same problem. I travel to New York quite a bit. My phone would give me a message that it was unable to connect to the GPRS network. So I would go into the Comm manger and deselect the 3g. Then the phone would get a signal. I was not getting a 3g signal, but an edge signal. When I would come home to Ft.Lauderdale the phone would work fine no problems with the 3g till last week.
Soft reset I get the 3g signal 4 bars then it disappears I get no signal ! and then I get an Edge signal in about 5 seconds or so. Everything works but I am unable to get the 3g speed.
If I try to force the phone into a 3g signal by selecting WCDMA on the band I can get a 3g icon. The voice part works fine and displays utms but any time I try to use the data I get some sort of error message. Like dialed "proxy" no response or the remote party would not connect.
Do you think that we might have something corrupting the radio?

My old at&t rom doesn`t give me the option of selecting the band. Maybe I should flash it with HTC rom and at least get the voice part to work. I don`t know if the security scanning machine at the airport will harm the phone in anyway. They always ask us to take out the laptop and camera separately.

2G/Edge/GPRS data issue in many places especially while roaming

My Incredible S has problems accessing internet using 2G/Edge/GPRS data plan.
The connection is established and I get the 'E' sign for Edge connectivity, but internet doesn't work in all the applications (data is only sending, but not receiving, down arrow in E is not blinking)
This happens mainly when I am roaming. But I have another android phone, Samsung Galaxy Spica i5700, which works fine in all places even while roaming, with the same connection/sim.
I enabled all the Mobile Networks setting related to roaming and restarted the device, but it didn't help.
Also, I tried doing a factory reset of the handset, but it didn't help, the same problem of no internet still exists !!
I don't know if this is a defect in my mobile or a general hardware/software issue with this model. I have already raised a case with HTC and I am thinking of contacting the service center for a repair/replacement of the device.
Does anybody has similar connectivity issues with 2G ?

I'm having the same issue. My EDGE works fine in chandigarh,INdia, but when I go on Roaming to delhi, it sometimes works and sometimes doesn't . I even sent a mail to HTC regarding this issue. The reply I got stated that it might be issue with the carrier.

Yes, have same problem with gprs, very flaky

I find the phone takes ages finding signal in general when i go from somewhere I've had none at. I'm talking 5 minutes in places I had signal straight away on my hero. Same network

Same issue here and it is not about roaming. I'm on my "home" network - O2 in Prague, Czech Republic. When phone is in 3G/2G mode all is fine (it is using 3G conection). When I switch to 2G only I have this issue. Sometimes immediately, sometimes it works for usualy very short time so I'm able to synchronize e.g. weather and then it hangs. No data conection anymore and one arrow next to ''E" symbol is active for long time like if phone is trying to send data. For sure it is not about network because my older phone works fine.

I have same issue. Edge and gprs is not working.
Unfortunately in my neighborhood poor 3g coverage.
On older phone (HTC Tatoo) with same sim card edge works fine. HTC support advised me to change sim card, but it didn't help.
And also IS frequently reboots and can't boot up to the last with back cover on, but only start cyclical reboots.

Perhaps someone who knows how, could set up a thread with a poll, to see how many experience data problems on gprs verses those who have no problem with gprs data. If its a lot of people it will help with a case to HTC customer supports ?

I have the same issue too. I,m on a very stable edge here in Trondheim, Norway, and sometimes it takes ages to connect to edge and sometimes not works at all, just saying "trying to connect" over and over in the settings-window.
To you with the reboot-issue when back-cover is off: This is due to the fact that the mobile-antenna for the device actually sits in the battery-cover on the backside. So when you take off the cover the Incredible S is without antenna
HTC Incredible S

I got my phone replaced through the service center and the problem is not there in the new phone ! It is working fine in all places and during roaming as well. So the problem I had was a device manufacturing issue. HTC Customer care was very prompt and I am glad the issue was resolved.

I asked HTC about this problem and they gave me a very convenient step by step method to set up APNs in my country and all that. I had very high hopes... but i still have that E with the blinking up-arrow and the not-blinking down-arrow.
No internet connection unless I use the Pass-through connection. A solution would be very much appreciated.

So should I take it that there are no solutions to this problem? Except for replacing the phone? That's rather sad...

This is probably unrelated but I had issues with my phone getting a solid 3g connection until I changed the settings to wcdma only instead of auto. Perhaps you can try setting it to gsm only?

[Q] vodafone uk 3g issues?

Having slight issues with my note on vodafone Uk, whenever I try to browse the internet and the 3g sign in status bar shows weboages don't load at all, when the H is showing bam they load really fast, and even when the E is showing they load but slowly, which is to be expected with edge. So why wouldn't it be loading when on 3g? Have I got some setting wrong on the phone?

HSDPA is faster than 3G.
3G (3rd Generation of Telecommunication Standards) is a standard of cellular connectivity which allows for speeds of up to 384 Kb/s downstream and 64 Kb/s upstream. 3G HSDPA is a 3G enhancement. HSDPA (High-Speed Downlink Packet Access) is a new mobile data protocol and is sometimes referred to as a 3.5G. Theoretically, HSDPA speeds can reach 3.6 Mbps downstream and 348 Kbps upstream. But the purpose of putting both on a smartphones is to make sure that your phone get internet access even when the other one is not available or have no access

possibly an issue with vodafone, have you contacted them to see if there are any issues?
as for the above post, totally irrelevant and hsdpa wil lgo alot faster than 3.6

Yeah they seems to think my sim card needed resetting, but hasn't made a difference, still does it. Hopefully someone has the same issues with a work around searched the net for hours, with not effect. The other weird thing is if its stuck on 3g and not loading I usually disable data on power button menu then er enable and H usually comes back and it works again, even if I turn it to GSM only in network setting, so Edge is only possible it works fine also just takes ages to load any pages which is annoying!

how long you had the sim card? it might be a provisioning issue with it

You think? Well I've had it a few years now like, 3 I think.

Vodafone SIM card works fine in my Note (SIM free from Germany).
I'd suggest try your SIM card with a different phone and try a different SIM card in your Note if possible to see if the fault is with your SIM card or Note.
P.S. Are you using any custom ROM? Could be a problem there.

No I'm on stock rom kka, yeah sure its something today with network or sim card, just rang them to get a new similar. Hopefully that will sort it out.
.

Fixed my issue, turns out it was happening a lot with people who have the galaxy s2, needed to enter code *#301279#, and release 5 hspa only, then disable fast dormancy mode on the phone, now I'm getting fast 3g everywhere :-D

It does say 3g and not just g?

if youre in the uk and only getting edge or gprs it may not be the phones fault.
I had a similar issue, we all assume we can get full 3G everywhere, not necessarily.
To solve this you need to buy the Vodafone sure signal box, it basically plugs into your home broadband router and then transmits full 3g around your house to whatever numbers you register on the box, including dongles.
The whole family can use it as you can register 32 numbers into it.
Cost about £50 new, i have a BNIB never been used or taken out of the box new one here, up for sale as it happens for £25.
Anyone interested should PM me....

Or you could just use wifi as you are at home anyway.

As I said sorted the issue it had something to do with the phone locking into search for hspa, and not reverting back to 3g when there wasn't any hspa signal. Apparently its a problem Samsung are working on. But the little fix of only scanning for 3g works for now, and I did a bandwidth test on hepatitis, and 3g, and 3g was actually faster. So not bothered.

Great find bud u should start another thread explaining the steps in a guide cause this is great info for Vodafone UK users

[Q] S III mini network issue

Hi guys,
I own an i8190, baseband : I8190XXALJL and I encounter frequent network outage.
Although the signal strenght indicator shows 3-4 bars, I cannot be called, cannot call and data is not being fetched.
On battery usage app, the network is most of the time "green".
On any other phone around me (blackberries, iphones, SGS II and III), and on the same network the problem does not reproduce.
If I turn the phone to airplane mode, and then back on, I am able to call, send mails so on and so forth.
Does any of you have the same problem ?
If any of you updated to I8190XXALL2, is this problem still persisting ?
Should I send it to the service ?

I'm currently running the ALL2 baseband, but previously had both the ALJL and the ALK6 ones and didn't encounter any such issue...
Before sending it back you could try with a different SIM card, maybe yours is acting up (it sometimes happens, especially with old SIMs).
Seeing how nobody complained of a similar issue though, I don't think that changing your baseband will have an impact, but if you'd like to give it a try you can download original firmwares (that contain the baseband) from here: http://www.sammobile.com/firmware/. In order to install them, just follow the steps in the root thread.

Will do so. I'm going to pit-stop my SIM card @ Vodafone and let you know about it.
It's strange that this happens only deep inside buildings (eg. offices, malls, etc..).
When this happens, usually the data activity indicator disappears OR the S3 mini is using 3G frequencies (not H, not G, but 3G)

Just changed my sim card and the issue still persists...
It's driving me nuts. My feeling is that the S3 mini doesn't lock on a network cell when 2 are available with similar coverage.
Will upgrade to the latest build and let you know about it :banghead:

And now the handset runs XXALL2 from vodafone uk.
I'm curious if the phone will have that network issue furthermore.

So far there's no difference. Where I live the network coverage is pretty bad, but it doesn't "disconnect in the background".
Only at the office I can test it out for sure or inside massive buildings.
ci6i, go ahead and update; install kies (for drivers only ), get odin3 1.87 and flash it with XALL2 from samfirmware.
Lately I see there is XALL3 available for some asian countries.
I still think that my BlackBerry 9810 is a tank. unfortunately vodafone romania doesn't sync emails two ways via BIS so... :crying: I had to get back to samsungs...

Well, i understand to lose signal if network coverage is bad, but my phone gets "network stuck" in the middle of town. I noticed this few times: at job, the phone stands on the table near me, and i receive sms about missed calls (i have voice calls diverted to voice mail when unreachable). If i try to call or browse the net at this moment, it's impossible until i set airplane mode on then off. All this time, the phone shows full network signal and HSPA data connection.
I'll try to change the firmware after hollidays.

As mentioned above, try to change firmwares (to XXALL2), I've also noticed some network drops when I'm at home (however this is expected in my case), but when I installed this firmware, I noticed some signal gain (full on 2G and +1-2bars on 3G signal).

Hi again.
The same issue even on xall2
Just happened again today in a crowded place.
It goes to "3G" from "H" and then it's gone off the network.
Will try with XALL3 although there is a small improvement concerning "sticking to the network carrier". It seems it'a hard job to get a call when in coverage area...
If still no success, I'll loose my patience with this Sammy...
See ya!

You get SMS because they use a dedicated network bandwidth for this technology and apparently the S3 mini does not loose connection on this communixation channel.
It appears that S3 mini is dropping voice and data, but not sms and CB (cell broadcast).

LJL version. No drops. Sometimes when i am on edge of 3G coverage area

Hi, i also have the problem with vodafone Romania. I can't place calls or use data connection. After reboot everything is ok. I tried to switch to Airplane mode and back, but no results.

Same problem over here

Hi bogdangr,
I have the same problem with my SIII mini. From time to time, after working normally, it loses the H or 3G symbol and shows about two or three signal bars, but if I try to make a call or receive one the operation fails miserably. The airplane mode trick doesn't work for me, and I have to reboot the phone to get it working again.
I've updated to the latest official firmware, but the problem is still there. Have you found a solution for this or anybody has more ideas of things to try?
Thanks you all,
MFC

I'm on VF RO, too.
Crappy phone, what can I say.
If it can't follow a network where there is sufficient coverage...

Hi Miguel,
The only workaround for this issue (at least for me) is to keep it in GSM mode (no "AUTO mode", no "WCDMA only").
So the crappy phone won't have to switch frequencies and I can get phone calls (I start considering a luck when the phone rings...)
I'm on 4.1.2 now baseband I8190DXALL3 (latest on samfirmware) and still the same.
You just don't want to know how's everything downloading limted to GPRS
BR,
Bogdan

Does anyone know what's that *# code that enables service / engineering mode ?
I want to select on which network frequencies is the phone allowed to work.
I want to disable 3G mode and leave GPRS, EDGE, and HS(D)PA only.
The reason is that when the issue appears, S3 mini switches from "H to 3G" and "G to 3G" and then it's gone;
Although there are moments when it can fetch data with network on 3G coverage without problems...

The code is *#*#info#*#* but it doesn't work .
I don't think it's a good ideea to disable those settings. Maybe it's a temporarily problem and i know Vodafone is testing/launching 4G coverage.
For me, this network issue is happening once in a week. How often do you lose phone signal ?

I found out the service code but the RF setup is not "sufforted".
Vodafone has implemeted already 4G in selected areas but it's not about that. On blackberry, iphone and nokia this is not happening.
As a frequency... 3-5 times a day while I'm at the office.

Can't connect to any freaking mobile network on cm based roms?

Hi guys,
I'm having some serious trouble with my phone not willing to connect to any mobile network at all it just simply says can't connect to this network right now. try again later and after 10 sec it goes into roaming mode :\ this only happens to me when i'm on a custom rom like MIUI, cyanogenmod, AOKP: all have these problems
maybe some important info:
carrier: telenet (in belgium running with a micro-sim)
phone type: C5303
working in stock rom with exact same APN settings!
I can make phone calls and send messages just fine
Someone who can shed some light on this occasion?
thanks,

Is it a "virtual" provider? If yes ROAMING is normal..

I don't know exactly but i do know that on miui on my old phone i saw that it said connected to Mobistar (appearently my carrier "telenet" and the carrier "mobistar are using the same exact network!)
EDIT: i found this on the internet Telenet Mobile is a MVNO that uses the network of Mobistar
so the hole roaming thing is normal then? won't it use more data or waste more money? i really just wanna have 3G or EDGE on the top like i used to have on stock lol it's a bit confusing having roaming at the top

A network using another ones network is called a virtual provider. Let me explain..
In Holland we have KPN, Tmobile and Vodafone. These three are the biggest one here. We also have Telfort, HI, Hollandsnieuwe and Simyo (or Simpel). These providers are called "Virtual" because they dont have their own antennas. They use the one from KPN (most of them) because this is the biggest provider in Holland at the moment.
The issue you describe sound very familiair. In the Galaxy S + section I've read about this issue and some users fixed this with turning ROAMING on. I did not encounter any issues like this on my Galaxy S+ at that time because im on Vodafone.
Perhaps this will be the solution for you? It also could be a CyanogenMod bug but I have no idea

Nice work tho
