I took delivery of my new SIM free Galaxy Nexus today. Everything appeared to be going well until I tried to make a couple of calls. The call would either connect for three seconds and then drop or drop immediately. After dropping the call the handset indicates that it has no connection to a network.It will also drop any incoming calls and then I lose the connection to Vodafone.
To reconnect to Vodafone I either have to turn airplane mode on then off again or reboot the phone.
When it has the VF connection in the connection status page I see this;
Network - Vodafone Uk
Signal Strength - -95 dBm 9 asu
Mobile Network Type - HSDPA:9
Mobile Network State -Connected
After attempting to make or receive a call;
Network - Unknown
Signal Strength - -113 dBM 0 asu
Mobile Network Type - Unknown:0
Mobile Network State - Disconnected
I called Vodafone and they are sending me a new SIM (I've had this one for many years now). The current old SIM works fine in my old Desire.
Anyone else have these issues or have any advice? Is this a handset issue, SIM or could it be a problem with the VF network?
Ah someone else with this issue! I thought it was just me. I find that the vodafone connection drops and won't reconnect - particularly when I'm driving along. Sometimes it's fine for hours and others it just never returns.
I'd be very be very interested to here if a new SIM fixes the issue, as I too have had this sim for a very long time.
I love the device, but if it doesn't function as a phone I'm seriously considering either changing networks or returning the phone (which I got from phones4u).
My old sim works fine in my nexus S (which my wife has taken over and probably won't give back!)
I am still waiting for the volume bug fix which appears to have a new GSM binary, that may help the issue (or not) - otherwise its a call to phones4u to get me moved networks!
I got the volume fix when I powered up the phone today but that hasn't sorted it. Im off to a mates house now to try his SIM otherwise I may have to send the phone back.
I've posted this up on the Vodafone forum too -> http://forum.vodafone.co.uk/t5/Goog...-Signal-3-seconds-into-call/m-p/943023#M12291
Just to update - tried with a mates Vodafone UK sim and it worked fine so its looking like my old school SIM needs to be updated...
Just been to a vodafone shop and got a new sim. Made three consecutive calls. A record. New sim seems to fix it!
Sent from my Galaxy Nexus using XDA App
I'm on T-Mobile in the US and seem to have this same problem. I had my G2 and G1 with this SIM and never had an issue, but brought it to the Galaxy Nexus and randomly I lose connection and it won't reconnect until I reboot.
Anyone else see this issue?
I had a similar issue with an O2 sim on an SGS2. Replacing the SIM worked for me, though it was only 2 years old. I suppose its inevitable SIMs will fail.
Unfortunately, I got a new SIM card last night and put it in. But it just happened again today. Anyone have any ideas?
Currently I'm using Android Revolution 1.3.1 and Kernel 3.0.1-ga052f63.
Hi , new to HTC forum,
I 'm facing a really strange problem with my HTC ONE X
I can;t connect to WCDMA networks at all. When I go into Network Selection , If I choose the WCDMA only option the phone goes offline plus in search for networks setting, returns, Error Searching For Networks
When I switch back to GPRS or GPRS/WCDMA Auto option , I got full bar signal with Edge connection.
The day before I was facing several connectivity issues, mostly sim went off and on again , due to bad cut - I think- of the sim card
The sim card I'm using now is also a cut version of a normal sim card. Is it possible that the bad sim card can damage something on the reception of the phone, or the new one does not fit well inside the phone(althought it is carefully cutted there are some tinny gaps between the card and the card holder) that causes?
I think that if this was an antenna option i wouldn't got any signal at all.
I have already arrange to change the sim card to a new already micro sim card
I'm trying to avoid sending my phone to service because the customer support is horrible here in Greece
Any help or opinion would be appreciated
Thanks in advance!
i have been experiencing several problems with S4 mini 9192 since i bought it one month back and one of these is that the phone does not switch data between the 2 sims correctly.
to have the data work correctly on any sim, all the below must be done
1-select the sim you want to use for data in sim card manager/data service network
2-have the same sim configured as gsm/wcdma (auto connect) on connections/more networks/mobile networks/network mode
when you select option one, the phone tries to perform task 2 too, but fails, thus the data sim is left in "GSM only mode" and will only have edge data, never connecting to HSPA/ 3G.
here is what i have to do each time to switch data from Sim-1 to Sim-2 (screenshots attached)View attachment Screenshots.zip
Screenshot 1- you will notice data is set for sim 1 and HSPA is active
Screenshot 2- select sim 2 for data
Screenshot 3- the phone will disconnect data on sim 1 to switch
Screenshot 4-phone will try to set sim 2 as "gsm/wcdma (auto connect)"
Screenshot 5- but gives alert message and fails
Screenshot 6- sim 1 is still on "gsm/wcdma (auto connect)" and the data connection for sim 2 is only edge
Screenshot 7- Sim 2 is still on "gsm only" and does not connect on hspa no matter how long you wait
Screenshot 8- for data on sim 2 to work properly, first change sim 1 to gsm only
Screenshot 9- then change sim 2 to "gsm/wcdma (auto connect)" and wait for 5 seconds, the phone will connect on HSPA .. success
now my big question is, does this happen to everyone with s4 mini 9192, or is it just me??
by the way, this occurs on both my Egypt stock firmware and the j2 india firmware i just flashed.
i tested a friend's Galaxy Mega 5.8 Duos, and the phone performs both steps by itself, with no need to perform the 2nd step manually.

I have had the same problem with my model that I bought in Australia. Your solution worked well for me as this is one frustration that I've been blaming on the network rather than the phone for the past week (because I was ignoring the error messages). I would hope a software update is in the works to fix this issue as it will get quite annoying in time.
I have the very same issue, plus the second sim slot only work in GPRS, and I try 4 rom before getting block by ****ing knox problem.
Sorry to dig this out but i havent found any answer to this yet.
is there any way to get a widget or a script or anything so that one can easily switch data connection from one sim to the other by one click? Or even automatically depending on which sim is in its home network?
This would be awesome as i'm hopping across the border twice a day and switching data connection all the time is a pain in the a**.
Thanks a lot for any answers!
I am also looking for answers for this.
Out on the site I work at they only have 3G towers but I have no data access on my work phone so I need to use my personal sim for checking email, then switch back so I can use work phone again.
Known issue on the phone it sucks

Thanks for posting this, finally i can have 3g on sim2!
Some months ago my phone started to behave strangely.
I have 2 sim card both for Vodafone. I use the data connection from the 1. sim.
Once i start a call from the second SIM card the phone drop the data-connection from the first sim(as expected) but after the call end the phone seemingly connect back to the 3g network but I cannot gat a byte from the internet.
I tried to switch between the cards and the result was that if I use the 2g in the second slot and start a call from the first sim the phone easily connect back to the internet after start a call.
also this is the case if the data connection in the 1. sim is 2g and not 3g.
So the main problem as i can see is that if i start a call from the second sim when i use 3g data-connection on the first sim after the call ends the phone cannot connect back properly.
If I turn on and off again the data-connection is not help.
But if i switch between 2g and 3g on the first sim the internet can be used again.
Please advice.
Shall I sand it back to the Chinese retailer? from Hungary
I have a strange problem.... That I use dual SIM 4g+3g/2g, whenever I go-to a place where there is no signal..... When I come back to area where there is network, 4g come back immediately but the other SIM won't take up the network signal..... Then only solution to get back both network is switch off n on... That too requires multiple try....... Is that phone problem ?or SIM problem?....or a software problem?(updated to marshmallow)
