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.
I had this problem: In my galaxy s4 mini duos (gt 9192) I use both SIM cards for voice and the SIM 2 for data connection. So SIM 1 is in GSM only mode and SIM 2 is in GSM/WCDMA auto select mode. I leave the mobile data always on and I got lot of dropped calls to the SIM 1. Every time I pick up the phone there were lot of messages which were Missed Call Alerts to the SIM 1. There was no problem in receiving calls to SIM 2.
With some testing I noted that the phone does not receive calls through SIM1 whenever the data connection indicates H+ sign ( Data connection is though the SIM2). Yet I could receive calls when that data indicator indicated as 3g. Finally found a solution to this.
Solution: Go to Settings -> My Device -> SIM card manager and put the tick on Receive Incoming Calls, which is the first entry under General tab.
It gives a warning message saying the data speeds will be reduced by enabling this option. Still when I enabled that option, I did not see a significant reduction in speeds. I get all the calls from SIM1, yet the data connection drops whilst the phone is on a call in SIM1.
Think this works vice versa, that is Data is on SIM slot 1 and voice only SIM is on SIM slot 2.
May be this is a well known thing. I posted as this might help someone.
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
Phone looses 4G Data & Call function on turning off data. APN Settings auto deleting.
Hey, I bought a Nokia 6 2018 a couple days ago. Its great but has this one problem. I am using the Indian Model TA-1089.
I have 2 SIM Cards, one is by carrier JIO and another by TATA DOCOMO. I use the JIO SIM as prefered SIM for Data, Calling and SMS. When I put the JIO SIM in SIM Slot 1 and start the phone, it works uptil I turn off Data. Once I turn off Data and let the phone sit for a few mins, the next time I turn on Data the phone doesn't latch onto 4G connection and I don't get internet connection. Also, I cannot place any calls via the same SIM. When I try to place a call, I get a popup saying "Mobile network not available". Although I can receive calls for some reason.
While trying to find the cause of the issue I found out that when the problem occurs, the APN settings are automatically deleted from settings. If I try to manually add APN Profile with the correct values and try to save it, the profile doesn't get saved at all. Also, resetting the APN does nothing.
I tried resetting the network but the problem persists. Factory reset didn't fix it either. Tried another 4G SIM and the same problem occured with it.
Restarting the phone fixes the issue temporarily. So does deactivating and activating it. But its such a hassle.
Surprisingly when I put the JIO SIM in SIM Slot 2, it worked flawlessly. But it still doesn't mean the SIM slot 1 issue is fixed.
Has anyone else had this issue? Please help.
4G LTE data works on both sim slots but only 1 at the time and only on the sim slot that i have set as the preferred data slot. Does anyone else have this problem?
When i make or receive a phone call on the secundary sim (not the primary/preferred data sim) i lose data connection. The primairy data sim is then automatically switched off. I have of course the Enhanced LTE toggle switch ON on both cards in network settings but this does not seem to work properly.
When i make or receive a call on the secundary sim the 4G LTE connection stays on for voice but the phone does not switch the data connection to the secondary sim card. The network connection on the primairy card is then also shut off completely. No network signal. So i cannot use internet during a voice call and also cannot receive a incoming voice call on the primairy sim.
Both network icons then show an "X" on the signal bars but strangely i keep the voice connection.
After I hang up the voice call on the secundary sim, the 4G LTE voice and data connection comes back on the primary sim and both signal bars go come back to normal and the "X" dissappears.
When i make or receive a 4G LTE voice call and surf internet at the same time on the primairy sim there is no problem. I have a Volte connection so i can voice call and surf on the internet simultaniously on 4G LTE.
This secondairy sim slot problem was NOT a problem on Android Pie on my Mi A2 lite. On Android 9 I had 4G LTE VOLTE HD voice and data on both cards all the time always. I could receive and pick up calls on both cards at the same time and keep data connection.
After OTA to Android 10 I soon discovered this problem. I did factory reset. I switched the primary sim, switched the sims in the tray. Nothing makes a difference. 4G LTE data works on both sim slots but only 1 at the time and only on the slot that i set as the primary data slot.
Does anyone else have this problem?
