[02 2g/3g] losing 3g signal and does not fall back to 2g/edge?

Hi Guys
well did a search and couldn't find a topic about this, however if there is Sorry.
Anyways got my 02-Uk simplicity yesterday and set 3g and MMS up all fine, and was working fine, however today I came to work which is a bit out in the sticks so hard to get a 3g signal, and because of this i noticed I lost all signal.
after playing around I noticed that switiching it to "2g networks" i managed to get a full edge connection. My question is how come if it loses the 3g connection does it not revert back to a 2g network? I know there is a 2g connection beacuse if i do it manually it works. is there a way to do it automaticly?
also i do have data roaming connection active, and can post my APN details if anyone thinks that will help reslove the issue.
Thanks
matt

Brought mine in to t-mobile to ask the same question. they said just stick to 2g only when you're not in a known 3g area. They also recommended just turning data roaming off

I have the same problem with my Goophone Y6.
2 solutions I know:
1) Flightmode on/off
2) Reboot
This is very anoying, because the bug apperas again. One question: Do you lose signal when you turn your display off or after approximately 5 minutes?

[Q] WCDMA - No or intermittent service

I recently upgraded to Gingerbread with Continuum 5.5.1 and love the ROM. But I'm having trouble staying connected to AT&T.
If I set the phone to GSM only it seems to stay connected. However, if I try to set it to GSM/WCDMA or WCDMA only, I get intermittent service or none at all.
I've searched and seen a few mentions of related issues but no definitive answers. Is anyone else experiencing this? Any ideas on how to resolve?

Try different modems

Thanks, I'll give it a try. I Reset the wcdma band using Samservmode and that has helped. Still jumps on and off a lot though.

Switched to UGL2 modem and it helped significantly. Thanks!

[Q] CM9 Roaming issue

Hi All,
Here's my roaming dilemma. There's an R beside the signal frequency and it won't go away.
Relevant information;
I have recently switched from CM7 to CM9 for the captivate. i'm using the latest version (14). from http://forum.xda-developers.com/showthread.php?t=1363760
I'm on a Canadian network with a company called Fido, which is owned by Rogers. My APN is set to "Fido Default" and my network is Rogers. this would NOT be roaming since it's the same company.
i ran the phone info using *#*#4636#*#* and it says "Roaming: Roaming" essentially the roaming is ON.
After this i downgraded back to CM7 and tried running the same options. the result was identical. APN is "Fido Default", network is Rogers BUT in phone info it says "Roaming: not Roaming". Essential the roaming is OFF, which is correct, there was never an "R" beside the signal strength in CM7.
Can anybody please help me, i'm not sure if there's a setting that i'm missing or dont know about. or this could possibly be just a bug with CM9.
Since i'm new to this forum i don't have my min 10 posts to post in the development side so i've had to post here.
If there's any more details that you need me to check to give you the relevant info plz let me know and i will get hat asap.
thx

I wonder if it is just a quirk in how it recognizes the network. I have an AT&T Microcell and, while it shows my carrier as "Microcell" on Samsung-based ROMs, it just shows "AT&T" on CM7 and CM9. Not the same issue, of course, but there is apparently some control in the ROM or kernel on how networks are displayed. If you don't get any hits here, report it in the CM9 forum once you have enough posts and see if anyone has any ideas.

well my phone is originally AT&T, and when it turn on the AT&T logo and everything is still there. so it could be still a weird way it recognizes it.

fixed. figured out all i needed was a new modem.

Care to share which modem you found that works with CM9 and the ATT Microcell?

[Q] Holoblur 4g problems

Hi there. I saw in a previous thread that someone was having trouble with 4g on the atrixhd holoblur build. The advice given was:
TecknoFreak said:
Turn it on manually by typing *#*#4636#*#* from the Dialer. Make sure you select the LTE / GSM only. And then go to Settings-> More-> Mobile Network-> Make sure you select or have the 4g selected
Click to expand...
Click to collapse
I just installed the tuned version last night and I'm showing a few differences from the advice given here. First the closest I have to LTE/GSM is LTE/GSM/WCDMA. When I select it, it works. When wifi takes over it reverts back to wcmda preferred and I have to set it again. Also, when I go into the mobile networks, there is no option for 4g. It's just 2g or better 3g or better or automatic. Any ideas what might be up? I installed from what I believe is the official thread for this: http://forum.xda-developers.com/showthread.php?t=2356624 Should I be installing the performance version?
Thanks for any insight you might be able to give!

[Q] CM 12 connectivity issues on Verizon 3G

I have the N6 running the latest CM12 and everything works great on Verizon as long as I am in a 4G LTE area. As soon as I leave 4G area I get a data roaming message and exclamation mark on my Verizon signal status bar. I have confirmed that stock rom will switch from 4G to 3G no problem but CM 12. I have looked into confirming APN settings but for some reason there is no 'APN settings' under the mobile networks settings fir me to confirm. I am just wondering if this is a common issue with CM 12 or just me. I was unable to find a thread on this so forgive me if this is a duplicate. Thanks.

I had the same issue with Liquidsmooth ROM. LTE works great 3G didn't work even when I enabled data roaming. I also couldn't send/receive mms while on 3G. Had to go back to stock rooted until the devs get this figured out.
