I see this issue since I subscribed 3G few weeks back.The screen comes on by itself with a popup of SIM Refresh.I am on stock LR6 with network set as GSM/WCDMA as required for 3G.It seems to appear even when the data is disabled .Any one has any solution ?
Ok , I called Vodafone and they advised to replace the SIM with a new 3G SIM.After then the problem seems to be solved...

Hi. I just bought a new galaxy s from vodafone, but when i tried to use a 3g data connection it just won't work. it works fine with wi-fi connection but if i turn that off (or if i don't use it at all) the phone just won't connect to the internet. i've double checked the apn settings...is there an option to turn the data connection on and i'm just not seeing it? please help...
sometimes it helps to restart the phone
or switch it to airplane mode then back
Did that
i've read other posts for other type of connection problems and i did what u said...nothing...it just doesn't even try to connect...
do you have any other SIM card from friends/family that you can try?
just wondering if it's related to your SIM account, or if it's defective phone
if it is working over wifi there is still something wrong with apn settings or your sim card.. i doubt it is the phone itself.. or you are in an area with no 3g edge.. or wrong phone ie t mobile vibrant on bell or att network

just yesterday i was complaining to my phone company about something similar
Hi,
I never test with 3G SM before with my phone.
I have changed my Vodafone plan to 3G and started using it.The SIM is working fine with 3G in my old mobile (Sony Ercsson).
When I put the SIM i my HTC it is not detecting 3G Network.If I choose GSM/WCDMA it is selecting the 2G Network and for WCDMA Only option
it is not showing any network.
Please note I am having the HTC mobile fro HTC Hongkong and now using the same in India.
Operator: Vodafone
Activity Performed:
Restart the phone and put off the battery multiple time
Factory Reset
Use another 3G SIM which is also workng in my old phone
Toggling between flight mode and WCDMA.
Results:
Just received the 3G network twice and it was sustained for 20 minutes and so.
Please note I am having good 3G Coverage in my locality and with my old phoe it always come full signal.
It happens some time
I have to disable / enable 3G to make it works.

Even I am facing the Same issue!!!
Not able to connect 3g and h... Please provide any solution for this!!!
Hi
I am in Kolkata India and recently switched from a 2G to a 3G plan with Vodafone Kolkata. Ever since then, my problem is that I am unable to connect to 3G using WCDMA. Neither voice nor data works. If I revert to GSM only, then voice and 2G works fine. Wifi has been fine and my saviour at home.
Phone details: Sony Xperia SP C5302 running Android 4.3 build 12.1.A.1.205.
I have confirmed with network service that it is not a SIM card issue, by carrying out the foll. tests already
1- Signal strength in the area of use : At the time when I am unable to connect to 3G, my colleague sitting in the next desk and using a Motorola phone is consistently able to connect to the same 3G network from his phone. So the network strength must be fine.
2- SIM damaged or dirty - I have obtained a new SIM card as replacement, after this problem started, from my service provider yesterday. But the problem is not resolved.
3- Manual network search and connection - I have tried this many times, using WCDMA only or WCDMA(Preferred) options. In either case, only on rare occasions, the phone was able to connect to a network. However, 3G data connection (H+ icon) did not show and then the phone disconnects from network. On most occasions, when I manually attempt to connect to the 3G network, I get the message "Could not register to the selected network. Make sure SIM is inserted."
3- Trying different SIM/Handset - I have tried out both options of switching SIM and handset.
- My SIM on Motorola handset - connects to H+
- Another SIM on my Sony - momentarily connects, then disconnects and then does not connect to network.
Please let me know if anyone has faced similar issues and found any resolution. Thank you in advance.

I think that there's an option to use 2G instead of 3G in the settings menu, have you checked to see if that is enabled?

That is the WCDMA option I've mentioned about, there was no other setting for this.
Anyways, it turned out to be a hardware problem. Got the "mother-board" replaced for free as it was under warranty & now working fine!

Good to see that you've sorted out the problem!
Hello. About a 4 months ago i have bought from eBay a note 5 at&t version. I live in Greece and my network operator is WIND GR. The phone works fine but from time to time i get an emergency calls only message. And i can't get and do a phone call. If i restart the phone everything goes to normal. Sometimes it goes on and off by itself (the problem).
Have been anyone experiencing the same issue? If the phone is incompatible with my network operator should it not work at all?
Did you tried to change the sim card? Maybe issue is from sim or from sim slot

My sim is new. When i purchased the phone i have changed my old sim with a new sim 4g compatible.
It happened again. And i am missing calls like this. I will smash it with a hammer
Go to settings, backup and reset, then reset only network settings, see if any better signal

Done that right now. Tomorrow i will get a new sim card and i will post if anything gets better. Thanks for the help.
Update of the situation. I have changed sim card 2 times. It still happening. My phone runs at nougat now and the problem still appears as before at 5 and 6 Android version. I currently gonna change service provider that has better and stronger signal. From what i have discovered. When the phone looses signal due too poor service provider signal sometimes it can't register to network by itself. If i enable airplane mode and then turn it off it comes back. Any clue? If it's hardware issue what can i change?
Should i have at the mobile networks auto detect or manual and my carrier?
Hi guys, I have an issue with 4G after the last dec update. In 4G/3G/2G auto connect mode, usually the receiving data arrow ( v arrow below the 4G symbol in notification bar) gone missing and thus the connection got lost. Only transmitting arrow is visible (the ^ one). I have to wait for some minutes or turn to flight mode and back to get my data connection back.
In the beginning I don't really sure this issue is caused by the latest update, but after I tried nearly everything, including factory reset which is doesn't help, I think that the update is the problem.
I have tried my sim on another phone and it worked normally. I have tried another sim on my note 8 and it got the same problem.
Oh and this is only a 4G issue. My 3G works normally. And before the update, I never experienced this kind of problem.
Two of my friends got the same note 8 and one of them is also using the same carrier as me, but neither of them experiencing this issue.
Anyone can help?
Thanks in advance
I had this issue too, it seems 4g connection only got the problem...,
Problem solved, they replace my device
I have the same problem but seems like in a different way, when I got the phone first time I contacted my service provider to activate the 4G service cause it was inactive on my line due to provider's issues, anyway the phone worked on 4G for only 2 days, after that it kept working on 3G, I contacted the service provider many times but they have no issues with my SIM or handset.
I still don't know what is the problem, is it a hardware malfunction? Is it an installed app? Is it a Samsung Update? I don't know!
have tried getting a replacement sim card, I had same problem in the past and they had by mistake sent a sim that was not 4g, got replacement and problem solved
Well, the problem is that it worked at the fist time on 4G so the SIM was 4G not 3G, but I have just comeback from their store, at the first the technical support did something in their system and switched the phone to airplane mode then turn the network ON back and the deice worked on 4G but after a couple of minutes the phone switched to 3G without going back to 4G, then he advised me that this problem either a SIM or handset problem and it's always 90% SIM problem, so we changed the SIM card and the phone is working on 4G for around 30 minutes till now, I hope it will keep working on 4G
2 days and phone is still working on 4G, it was a SIM card problem
Aoa dear
