Losing reception

Hi
I have an unlocked g1 using a three sim in the UK.
I have only had it about 10 days, for the first 5 days or so it would switch to 2g quite a lot and not switch back, which was not too much of a problem.
But for the last 3 or 4 days it will completely lose connection up to 4 times a day, only way to fix is to restart or choose the 3 network again in the options.
I had the problem originally with the standard tmob rom and i have switched to the CyanogenMod yesterday and updated the latest radio again and it has just done it again.
it even does it if the phone is just sat on the desk.
Anyone else having similar probs?
cheers

Carrier? Have you checked if they have problems?
Tried your SIM in a different phone?
Tmobile is the carrier..now i lost my signal all together....I dont have another phone to try my sim out on
ok...so both data and service came back for about 30 seconds...i got two white arrows going around in a circle like it was updating something then i lost all connections again and says emergency calls only
any ideas?
ok...i have this weird folder on my sd card named .android_secure...dunno where it came from looks new to me
data signal lost here
Hey, I'm having the same problem here, no weird folder in my sd card though. Went to bed last night everything was fine, woke up and my apn list was wiped.... I reset everything in the apn and still no data connection but I have service. I'm running the latest Cyanogen mod stable for nexus, almost seems like an update was attempted last night and since i"M not stock things went crazy....
Call t mobile and see if there is a data outtage.
I had no signal for like three hours last week.
tmobile uk? mines down too. manchester area.
sim cards do go bad.... i had this happen last year... maybe go to tmobile and see if you can get another if there are no reported outages.. the probably wont even charge you if you go to a corporate store
so i called tmobile and they said they knew what it was...had to turn my phone off for two minutes and still waiting to see if it worked..but i dont know why the sync or update arrows were showing up on my notification bar. sure hope it was Froyo passing me by

where are you, uk or usa?
I've had something similar happen to me as well. This was a few weeks ago. I live in Chicago, and use T-Mobile for what it's worth. I ended up pulling the battery for a bit and rebooting. I got the data connection back.
Sometimes though, the data connection will seem to hang a bit and I'll see the flashing arrows and sync icon as well. It seems random, but the last time it happened to me was yesterday.
back
It must have been a localized black out here in Washington State (US) because my data connection came back on just now after 3 hours of being shut off. For awhile there I only had edge and no 3g and without me doing anything 3G and H have connected back on.
Well that's good. The optimist in me says that the outages and weird issues are related to the upgrade of HSPA+ for us Let's hope it's true.
I had the same problem in WA. Data has also been restored here.

MMS issue after gingerbread update

Has anyone else had issues with sending/receiving MMS since the gingerbread update? I have been unable to send/receive for the past 2 days and the update is the only thing that i can think of that may be causing the issue.
Any help would be great!!!! THANKS!!!!
I can't receive
Sent from my PC36100 using XDA App
I'm Running stock with no root its working fine.
ive been having that issue with all gingerbread related ROMs that ive flashed and around 1 AM i start getting 1x instead of 3g and it makes messages forever to send and recieve
my mms take at least 30 minutes to send and 10 to receive
Not sure if this is an EVO issue, more so than a Sprint issue (On Sprint Android phones at least). I have had 2 different Android phones before the EVO which were stock, and have a daughter and wife that both have stock Android phones on Sprint. I have never seen proof that more than 1 in 4 of any MMS messages have ever been received successfully (to family members on Sprint). And I can't count the number of times someone has mentioned sending me a "picture" that I never received.
When I switched to the EVO (even before rooting and going to CM7 -- and even more so after) -- this trend did not change for the better. Sent 5 pictures yesterday to 3 family members (all on Sprint with stock Android phones), with not a one of them ever showing up on the other end.
I haven't been able to send or receive MMS since last week. I'm wondering if it has to do with the new radios because is started around the time that I upgraded them.
I've also noticed that my phone doesn't sync my inboxes through my HTC mail app anymore. It doesn't sync the Friends Stream widget, either. I have to do it manually.
Edit: I went back to Myn's 2.2 rom but left the newer radios on. I'm almost done downloading the lastest Synergy nightly and I'm going to try MMS with that rom and see if anything changes. I'll provide an update later. Although I will say my phone was acting up when this happened and I had to call Sprint because I lost all 3G connectivity. After 4 phones call to Sprint, one was able to get my 3G working again but my MMS or sync stopped working afterwards and I just haven't had time to call Sprint again.
Edit: Using a 2.3 based rom did not fix my MMS issues. I still can't send or receive them. I guess I'm going to have to get on the phone with Sprint again. Fantastic.
I am also having this problem since June 5. I updated me and the misses evo Saturday night and was getting text but my phone was getting low space notifications 5x on Sunday so I did a factory reset and now I cannot receive text messages. I can send them out but not receive. Called Sprint tech support on Monday was in the Sprint store on Tuesday from 10am to 2:30pm and no fix an e ticket was put in on Monday for me to have the phone replaced. The store didn't have any evo's in stock how crazy is that. Today is Friday and still no new phone. I called Tuesday afternoon to tell tech support what was going on spoke to 11 different people order was put in for a new phone.
Now today my phone is dropping calls after 5 mins of talking and a really bad echo can be heard. The misses phone is working perfectly no problems what so ever.
I send and recieve just fine, but it does take forever to go through, sometimes up to an hour. I am running stock IT'S 2.3.3, but it was that way under Froyo with the old PRL, too.

Ok, after going through a bunch of forums I got mine to work.
First thing I did was go into ROM Manager and fixed permissions then rebooted.
Try that, if that doesnt work then also try
Use root explorer, and make sure it is set to R/W mode (read/write). Navigate to /data/data/com.android.providers.telephony/databases/telephony.db and delete that file, then restart your phone. After the restart, you should be able to send and receive MMS messages.
I did both and now I can send and receive on my phone and my wifes phone.
She is running OMJ 2.3.3 and Im running MikRom 1.03.
With mine, I can't download while wifi is on. Might be a setting I'm not aware of, as I've never had this problem before. Searched and couldn't find anything.
I was havin the same problems called sprint and thier answer was wait till we send out a MR thats all they could say. I wiped everything and. Seems to work now but still some issues. Call sprint and let them know couse the rep did say they have to hear about from more than one person to start lookin at issue

Sometimes not able to receive calls

SM-G900T - currently running stock MM ROM
Family Mobile (T-Mobile MVNO)
I've had the S5 almost four years now. Worked great on stock ROM, Cyanogen, and for a year or so on Lineage. For the past year, I've had cell network issues.
I started having a problem running Lineage, where I would randomly not be able to receive calls or SMS. In testing, I discovered that this would last for hours or days, until I rebooted the phone. Then it would work perfectly for a few hours and the problem returned. This was the same regardless of my location or cell tower, and who the call was from and what network they were on. I've never had a problem making calls or sending SMS, it's only been with incoming.
I've always been able to fix this by flashing back to the stock MM ROM. Then I would get tired of it and try Lineage again. Then I started having the same problem on stock, too.
I flashed stock a few times and finally got it working where I don't have the incoming calls problem, but there was a new problem. No LTE bandwidth. I started off with 7 mbs down and 100 kbs up. Now when I test it, it's 100 kbs for both. I've been running it this way for a few months.
Customer support from my carrier has always insisted that everything is fine on their end.
Now I'm afraid to flash anything, dreading the incoming calls issue will return.
Are there any diagnostic steps I can take to figure out what the problem is?
