Problems losing signal while driving with 8125

So I have been able to repeat this problem. I noticed it just started happening in the last 2 months or so.
Scenerio:
I turn my phone off (or screen off), start driving say 3+ miles. When I get out of my car, I turn my phone back on. Then I notice the EDGE icon has a X and the signal bar has a X. It then proceeds for about 5-10 seconds finding a signal pretty quickly.
Now I know for a fact that during this time when the phone is off, I am unable to get calls because it doesn't look for a signal until I turn the phone on. This is a pretty big problem as this obviously shouldn't be normal. Anyone else experience this?
I currently have the standard 64K sim, didn't get the 3G yet.

anyone experience this?

i guess it depends on where u live, and where towers are located.

I haven't noticed this behavior.
What's the deal with the 3G SIM? Can we swing by any Cingular store and pick one up? What's the benefit over the 64k chip?

It sounds as though the 3G card doesn't benefit the Wizard at all, too bad this brand new device doesn't support the newer technology

3g isnt even available anywhere yet. i think its only good on 4 city blocks of NY or somewhere completely remote. 2008 i think

im in nashville, 3g works nearly all over nashville on my blackjack. It would be awesome if it worked on my 8125 aswell, sadly, only edge is working!

No internet on edge PERIOD!!!!

I hate to ask this........if its in another forum or not but do you guys have the same problem running your internet when you are on edge. What sucks is my house switches from H to E and when on E there is no action. If there are others let me know cause I this is my second phone already due to black screen.

I get internet access on edge... it's slow but it works.

I'm having the same issue with the edge... I'm in Salt Lake City, where are you?

Same here, in southern Arizona. This is also my second phone. First one bricked mysteriously I can't access the app store or do ANYTHING data-related in EDGE mode. 3G works very well, but I get nothing whenever I'm in EDGE. At least I have wifi at home.
I've called customer support and their recommendation was to do a factory reset. I tried that, no improvement. I get slightly more stable connections after changing my radio to GSM (auto PRL) in the phone information menu, but it's still awful.
I'm thinking of calling back again in a week or so and bugging them to give me a third phone. Maybe the second batch with tighter hinges will be out by then...

I am on my third G2 and all of them have had much the same issues. All have had loose hinges. The last one I received started out by rebooting on its own as I charged it. With my Nexus One and my Vibrant I always get 1-3 bars of 3g with the G2s I get virtually no H consistently or 3g and 2-3 bars of E or a lot of G. This last one will go from suddenly having 4 bars of H to 1 bar of G it just does not stay on H and I get numerous No signals. Getting on the market at times is frustrating and downloading is a real adventure. I like the phone but am becoming disenchanted as it seems with this last G2 I am uncovering different problems every day. I have had black screen freezes random reboots etc. Also while in a conversation on the phone it put the call on hold without my doing anything. Perhaps the sensor malfunctioned and my ear hit the hold or mute button but this should not happen. I have also dropped calls and have had calls come in with no notification except for notice of voice mail after the fact. I am about ready to throw in the towel and send it back for a refund. If anyone has any ideas or fixes for any of the issues I have mentioned I would greatly appreciate hearing them
Just had a screen freeze and when it booted backup by itself it just went into a loop of home screen to black screen and home screen to black screen. Had to power off and pull battery and reboot and it now seems okay. That probably does it for me. I am tired of the constant problems and after 3 devices all with similar or same issues and more being uncovered every day,I am coming to believe that another replacement will not be the answer.

Yes this happens to me pretty often. I live in a building in Brooklyn NY, and when I am moving around in the building, my data connection goes out and I get 5 bars of signal but no data, no G, E, 3G or H+.
Also if I'm in an area where data connection or the signal is spotty, it will go from H to E and then back to E, and then give me a error about not being able to get any data connection.

keep losing network connection

I have a Vibrant...stock and I haven't received the update yet. Houston, TX area.
For the past 3-4 days, I keep randomly losing my network signal. No 3g, no Edge. Rebooting the phone or putting it in and out of Flight Mode will wake it up. Otherwise I think it would stay dead regardless of what I do or if I move around. I am in normal areas that should have decent 3g signals and have never given me issues before with this phone.
Any ideas? Maybe weird network issues in the area or definitely a problem with the phone itself? Maybe the OTA update will clear it out?

This actually happened to me couple times last night, first when i turned off wifi and 2nd time i was on 3g and suddenly data signal was gone completely
I'm on ji6

Same problem here. I upgraded to froyo and then get back to 2.1. Had a fix drawbacks but it is now working fine until I noticed this problem where the signal is dropped. Sometimes it says that the sim card do not allow to connect to that operator, but when I try a few more times it reconnects. I'm waiting samsung release again froyo to update the phone and try to fix this problem.

[Q] my G2 loses service, restart brings it back

hey everyone
so my G2, which I absolutely love, has been having a problem lately. in the first week it happened maybe once and i didn't think much of it, but since Friday it's happened like 8 times now. I'll be sitting there with my G2 and all the sudden I have no service whatsoever. Just an x on the signal strength indicator. 1 or 2 times it has come back after a minute or two, but the other times I had to turn the phone off and back on. the weird part is I'm not moving at all, totally sitting still, but when it comes back on I have FULL bars with HSPA+. so it's not like I walked into an area that didn't get good reception.
any idea what's going on? i looked around but didn't see other people having this issue. any ideas?
thanks

alright well at least i'm not alone. i remember that rumored OTA update was supposed to have some radio bugfixes. maybe when the real OTA update comes it will have something to fix this. i hope so.

I have been trying to diagnose this issue on my phone too.
By any chance, do either of you have your BT on at the time?

Happens to mine as described and I have never turned on bluetooth. However this would also happen to my G1 so I think its a network thing personally.

Yeah, it definitely is. I have 2 areas that it happens in, both are while I am in my car and I have BT on in my car. When I ran it without BT, did not happen.
I have found that when I am in those area's, turning off 3G stops it entirely, even with BT on, so when in my car, I set edge and still use my BT and problem is gone.
I hope this is temporary and an OTA can fix the handoff from 3G to Edge and back better so that I can stop this, but this works well enough.

Mine has done that also, maybe once a week for the past 3 weeks.
Judging by the other problems you can have Id say this one isnt that bad. Especially if it only happens once a week haha. This is the only problem I have with my phone.

no bluetooth...
no no bluetooth on, i never do actually... but also my G1 never did this, which makes me think it's NOT a network thing, but I don't know.
also I'm sure this is just coincidence but it almost always happens when my girlfriend is nearby with her T-Mobile Blackberry Curve. i know it wouldn't make any sense, but she's sitting there on the same network with full service and all the sudden my G2 loses service completely, right next to her... although it's not always while she's there, but like the majority of the times she's been there.

I just started another post to check on something, I have widgets that show me when I am connected to 3G and when I am connected to H. I have noticed that the phone is activity managing that connection. In other word, it is in 3G until data is transfered then it goes to H. I wonder if when we are in areas of "questionable" HSDPA signal if this hand off is causing the problems.
I have seen a lot of op's say that there problems come right after some data activity?
Just a guess a this point

i saw someone mention in another post that it happens after/during a text message alot of times. i haven't noticed that myself, but that's something to think about too.

What I've heard is that the phone will stay in 3G mode until you begin using data in order to save battery life. Makes sense to me.

Mobile Data will not enable!! (Dynamic Kat)

I need help this is driving me insane!
I've been running Dynamic Kat Rom for about 6 months or so now. Everything was working fine then all of a sudden a week or two ago I noticed my mobile data is not enabling at all.
I can only connect on Wifi and only receive SMS.
I've tried
- Messing will all the data/network settings
- Turning Mobile Data on and off -- no effect
- Toggling Airplane Mode on and off as suggested in some places
- Wiping everything but Data and reflashing latest ROM
- Reseating the SIM card
- several other things I forgot..
I do see the carrier information in the top left (AT&T) and I am getting signal bars.. but not indicator for 4G/LTE/etc
I've been messing with this for a week now and it's driving me insane.. I can't get a connection anywhere unless I'm on Wifi.
Anyone have any suggestions? I'm not super phone savvy, but willing to try any suggestions anyone may have.

Hmmm.. weird.
So I called AT&T and asked them about it.. figuring it could possibly be a carrier issue.
They told me to try things I had already done 100 times.. turn the phone off and on.. turn wifi off... etc.
I turned Wifi off... (which I had done 50,000 times before) and 4G popped up.
I guess they did something. So.. guess it's resolved.

Problem has returned.. same issue. I will have 4G signal for hours and then all of a sudden it will drop completely and I can't get a data signal no matter what I do.
I see AT&T in the corner and have signal bars, so I AM getting some kind of signal.. but no data connection whatsoever.
It seems completely random and intermittent.. I can have data signal for days with no issues then I will lose it for days.
Restarting the phone 5-20 times sometimes fixes it.. but that's about it. Anyone have any ideas what could be causing this?

Bad signal / carrier issue?
Call them and report a fault in your area?

I have called them multiple times, they will reset the signal.. sometimes it will come back right away, sometimes it wont.
And this happens regardless of where I am. I know for a fact where I am right now has a great signal strength. I get 4-5 bars on average. But this also happens at home as well about 20 miles away, which also has a good signal, or anywhere I go really it can happen. This isn't in the middle of nowhere either, it's smack in the middle of SoCal (LA/OC)
I'm beginning to think it may be a SIM card issue or a hardware issue with the phone. I'm going to try asking them to send me a new SIM card.
Another thing I will notice is when I have a working 4G LTE connection, and I'm on Wifi... it will sometimes CONSTANTLY switch back and forth between wifi and 4G like every 10 seconds, even when I have full signal strength on Wifi and 4G.

Disable Smart Network Switching in WiFi settings
it's nothing but a buggy headache, disabling might fix most of your problems, almost certainly the constant switching back and forth

Yeah forgot to mention I have disabled that. It's disabled now. It solves the constant switching back and forth (when I actually have a data connection), but that's kind of a separate issue as the losing data connection.
