Network dropping. Has signal bars but says emergency calls only

Im running serendipity 5.11 with jk4 and speedmod.
This is the first custom rom I installed. I experienced several network drops. The phone says there's signal bars but it would say emergency calls only. I can fix the issue by just rebooting phone. But its annoying especially when om waiting for a call.
Im on the rogers network living in Vancouver bc. Would this be a case with the modem? If so what other modem suggestions are there? I prefer modems with hsupa enabled.
Thanks

Try to switch your mobile network mode to "GSM only" and then back to "GSM/CDMA auto". Try rebooting your phone, clearing cache/dalvik or fixing permissions.
Also, as far as I know, some ROMs do not support auto switch between 3G and HSPA (3G icon is displayed all the time). Usually custom ROMs switch between H and 3G to save power (H is used only when bigger network traffic occurs, in order to speed up your download speed), but many ROMs do not have this feature.

Forcing 2g, rebooting, etc., doesnt worked. I know that H is used for big traffic, but ICS dont even want to enter it when i download 10mb+ files..

hey there
as u might have seen im on eplus too and i faced such an issue several times with different phones
what i figured out was that in some cm9 roms the mobile hotspot (dein zugangspunkt ist ja normalerweise glaub ich internet.eplus.de ) is not available or there are mistakes in it so just get to the eplus providers homepage and check if ure zugangspunktname and all the other options dealing with it are set right
hauste rein

Everything was ok, now i changed back to gigabread+ from texten...
HSDPA works fine, seems so that ics is blocking connection like divibyzero said.

ICS doesn't block it you probably need to set up your APN correctly which is what I think the guy before me was saying too

WCDMA problem

I'm having this issue with WCDMA in which it constantly drops to 0 signal bars from full signal, and sometimes I even get disconnected from the network until it decides to jump to full bars again. This happens on all locations, ROM is stock XXLSC deodexed (got it from the user I9000 here in the General section) and the problem just keeps repeating itself. Signal drops completely, then jumps back to full, then fully drops again after a short period..it's extremely annoying since I can only use the slow GSM network, which is useless to me when I need fast internet. I called the network operator and they say they had zero reports on an issue similar to mine, so it's not them.

Maybe you should try another "modem" file or test another real stock Rom.
XXLSC isn't a stock Rom - it's based on the XXLSA leak from sammobile.com with the two OTA updates I got on my device. So it has bugs and you should see it as early beta.

after upgrading to JB i used to have similar issue.. loss of signal.. call quality issue.. i changed the modem to one for my location and it has improved a lot. You could try that too

My phone was recently in the repair shop because its usb port was busted up. Ever since I've got my phone back, I have this issue and the technician guys are baffled about what it could be. They just changed the connector and nothing else, I don't see how that can cause any issues with the reception. It keeps loosing signal every few minutes, only to jump back to full bars.

I'll just switch back to stock 4.0.4 and see if it helps, but I'm still quite sure that my phone worked fine with XXLSC leak for a long time.

Update on the situation......I gave the phone to the official Samsung service shop, they tried everything, from changing software to cleaning/changing antennae connectors, and nothing fixes the problem. Most likely I'll have to get the motherboard switched, which costs about 210 euros. Pissed beyond belief right now, would rather just throw the phone away.

[Q] slow mobile data connection

Hi, I have problems with my mobile data connection. It shows 3G or even H connection but it is very slow.I tested the speed with an app and I get max 192kilo bits per second with H and E connection.
I use on my I9001 SlimBean 4.2.2 build 7.8 with Kernel 3.0.89-K^Kernel JB4.2.2 OV UV 360.
I tried three different Basebands XXKQP, XXKP4 and XXKPM.
I'm in the US and my cell phone provider is simplemobile which uses the T-Mobile network.
I use theAPN settings which my cell phone provider suggests.
At the beginning I used my phone with the stock rom 2.3.6 and evything was fine.
After flashing to custom rom I got this issues.
Have anybody an idea how I can fix the problem?

maybe flash a different modem see if that helps

I thought base and is the modem driver? Are there More basebands then in the i9001 wiki page?

Try XXKPO-Baseband. It works fine for me. If that doesn't help, your provider could also be the problem. Can you take the sim-card of a friend or family member who has an other provider than you and try if this solves your problem?

I tried XXKPO-Baseband but the fastest download was 120 kilo bits per second even with 3G.
The thing is, everything was fine before I flashed to the custom rom.
I will try a stock rom and will report if I fixed my issue.

Have you tested an other custom ROM, for example CM? Maybe it is a prob of SlimBean ==> have you written this problem in the development-thread?

Depending on your area, built up? middle of nowhere?
These are things you need to tell people
Try any of these 2 : ZSJPG or BUJP5
I use ZS as I stay in the UK and gives excellent battery as well as signal strength
Hope it helps :laugh:

I tried also liquid smooth and a stock rom. But the data connection is still slow.
I tried a t-mobile prepaid card which uses the same network as simplemobile and I got 3500 kbits.
So called my provider three times but they could fix the problem.
The last guy told me that my phone won`t work with simple mobile. But it worked with 3G and H in the past ...
And every time I test my speed it has 120 kbits. Seems to me they throttled my speed.
Where can I get ZSJPG or BUJP5?

Maybe a stupid question:
Is your Internet data consumed and your Internet is because of this throttled...???

OK, before trying these modems are your APN settings set up correctly for your network provider?
LINK TO MODEMS HERE

OK, I called the support service line three times.
Yes, my APN settings are correct. My plan has 500 MB 4G then "only" 3G but "unlimited" what ever that means!
I think the best way is to change the provider ...

Or trying another modem first only AS a test...
The idea the others had...

Signal issues

Help.I have a galaxy note original.I'm running cm10.2 . every now and again the phone loses network.I have tried applying the tape trick.it hasn't worked.what I have been doing lately is whenever the phone drops network signal I activate airplane mode and off again then I get signal.it doesn't always work. Clearly this has nothing to do with sim card or contacts of the aim and device.I'm suspecting that it could be a modem issue.is it possible to flash an area specific or country specific modem?if yea,where can I find one that will play nicely with the 10.2 ROM ? Help
