Hi, I have a Vodafone Germany SIM card that I would like to use in Australia to receive text messages (for online banking verification).
I have it S-Off, rooted and converted to Google Play edition and it has the latest Lollipop firmware, if that matters.
I have been in Australia since February and this used to work perfectly fine (a couple of months ago), but today when I tried to use my German SIM Card again I got "Emergency Calls only".
When I go to Settings --> Wireless & networks --> Cellular networks --> Network operators, after searching it gives me a list of 4 different operators, as well as choose automatically, no matter which I click on it says "Registering on [network] ..." for about 1-2 minutes, and then tells me "Can't connect to network right now, please try again later"
I have tried all I can think of:
Rebooting Phone
Turning LTE/3G/2G on/off
Turning Roaming On/Off
Turning Data On/Off
Dialing *#*#4636#*#* and turning on GSM only/ GSM auto/GSM LTE auto
All to no avail.
I have no problem using my Australian SIM and had no problems doing the same thing a couple of months ago. My Phone was already S-Off, etc. then.
Any help would be greatly appreciated.
Hi, I'm on CM 12.1 and my OPO won't register on networks at boot (I'm on Virgin UK). I have to manually go to Mobile Networks > Network Operators and select EE (which is a network Virgin uses). After that everything works fine, I have network and data. But if I connect to WiFi, data will be lost when I disconnect and won't come back unless I manually register to the network again. Also, network will drop much more often since I only use EE and the phone won't automatically connect to other networks. If I go to Mobile Networks > Network Operators > Choose Automatically the phone disconnects from network and I get "Emergency Calls Only".
NOTE: The SIM works in another phone without problem. However, my other SIM works perfectly fine in my OPO.
CONCLUSION: My guess is that the settings for the Virgin SIM failed to download correctly. I had to manually add the Virgin APN to use data (which I usually don't have to).
QUESTIONS: Is there a way to reset the SIM settings stored on the phone without factory resetting? I might be wrong, any other ideas on how to solve my problem?
Thanks, Dan
I posted this in the "any question" thread, I hope it's okay for me to post it here as a new topic too --
S6 920F 32GB, stock, not rooted.
I have an issue with connecting to mobile networks --
The handset is network unlocked, but with a sim from my preferred network inserted, the only way I can get it to register on a network is to put the phone in 2G ONLY mode.
If LTE or 3G are on, it won't manually or automatically register on any network. I've taken it to a phone shop and with a different SIM on the same network, the same issue is apparent.
SIMs from two other networks allow the handset to register on LTE/3G without any problems.
The network's customer care team were unable to help, I've reset it, I OTA updated to Marshmallow, no change.
Do I need to reflash modem firmware or something? This is driving me nuts.
Thanks.
Hi,
The question may be ridiculous, but after using JIO sim, when I inserted my airtel sim, my phone is not detecting that sim. Has anyone faced this kind of issue?
If there is a solution to that please provide me a solution.
I had this issue few weeks ago. I solved it by turning off the phone and then re-inserting the SIM. And just for wait few minutes to let it register to the network.
Restart your device after inserting sim.
go here settings -> cellular networks -> network operators and choose automatically detect network or manually select Airtel Network
I am currently in Italy using a Vodafone UK sim card, it's been working perfectly (apart from randomly dropping complete signal periodically) but now it's just completely died, as in it won't find a signal at all to connect to any network let alone data roaming. I have contacted Vodafone who said there's nothing wrong at their end and the worst thing is it was working perfectly till this evening. So now it sometimes says emergency calls only or just the ring with a line through it as it cannot find any signal at all. I have tried doing manual network operator selection and automatic but still nothing... Any ideas? It's a g9550 128/6gb
Update I now have 3g data but it says "no network connection" and I cannot send receive texts or phone calls, yet I have full data...

Consequences of buying a CN/HK variant....
They usually have network connectivity issues, not surprising. Try removing the SIM card, turning the phone off, wiping cache in recovery, insert the SIM card, and then reboot. Then manually go and search for a network in settings and force it to connect to Vodafone Italy, should work.
It's working now again, I didn't do anything lol it just started working on its own accord! I'm now in Switzerland and all is good. My life is empty without my phone
It always happens to me when abroad. I am on O2. I have to select network manually and pickup different to the one which auto connect shows emergency calls only. Looks like some cells allowing me to connect but won't pass through calls
Do you also have a usa/china variant?
No, o2 UK from Samsung
