I have been using my Htc one from the past 2 years using the same sim card. Since i stay in India, the phone goes into roaming mode when you travel across states. So 10 days ago, i travelled to another state and my phone entered into roaming mode from then my phone cannot be connected to the network. I am unable to use the cellular services. Sometimes my phone works fine but the next minute, i loose the signal again. It is not in a stable mode, it keeps loosing and gaining the connection. Neither can i call nor i can text. If the phone gains signal, it happens only for a minute or two after that, it looses the network again.
My sim card is fine since i checked it in other phones. So the problem is with the phone or the sim tray.
What should i do?

Seems strange it happened after / during traveling
I have herd of others putting a piece of tape on the back of the sim to make it a little thicker. be careful doing this though the sim could get stuck in the phone permanently

My i9000m on the Bell mobility network is not picking up data after an overnight charge with the phone turned on. Today - nothing. I do have phone use and I can access data on WiFi.
I am running stock ROM. I unlocked the phone using a Rogers SIM card, about a week ago, but went back to the Bell network immediately after with no problem. After unlocking I got the Kies to work and updated to UGJH2. Since then, the network access has been spotty but I've switching to WiFi then switching back and it's coming back. I purchased this phone with a different Bell SIM2 then put my old Bell SIM1 (from an Omnia2) in this device.
*#7465625# shows Personalizatiob Status
network lock [OFF]; Network sublock[OFF]; SP lock [OFF]; CP lock [OFF]
What I've tried
1) Switching to WiFi and back - no data
2) Putting SIM1 back into the Omnia 2 - O2 booted up and accessed the Bell network including data. CONCLUSION - The problem is not the SIM card.
3) Putting the SIM2 into the i9000m - no network access at all; not even phone. This SIM2 is working in the O2 and originally worked in the i9000m. Much to my surprise when I put SIM1 back in the SGS it still picks up the Bell network.
4) Squeezed the SIM holder blew out with compressed air in case it's just a physical problem with the SIM being held tight enough - SIM1 still not picking up data.
So it would seem that there is a problem with my SGS reading SIMs other than the one in use when whatever happened happened. Any suggestions on how to get other SIMs, even from the same network, to work? If I have to submit my phone to Bell I need to re-lock it. How do I do that?
Thanks for the help.
--- update---
relocked the phone using *7465625*638*# then 302610 and my unlock code. Power off / on still no data access. Now *#7465625# shows Personalizatiob Status - network lock [ON]; Network sublock[OFF]; SP lock [OFF]; CP lock [OFF]
first try this
http://forum.xda-developers.com/showthread.php?t=789039&highlight=*#0011#
does it show which band it is using for data?
you can also try this
http://forum.xda-developers.com/showpost.php?p=8124344&postcount=45
install the APN on off
then flip it on / off and back to on
see if that helps
Thanks for the response.
I did the #*0011* It's flipping between the 850 on 5 and 1900 on 2 The DL and UL numbers are slightly different. I did have to reconnect to the APN.
How would this affect installing *other* Bell SIMS? That's what worries me the most - that it wouldn't read another Bell SIM that works in another phone.
the only time i see this happen is if you swap the SIM card when the phone is ON
if you turn off the phone, change between SIM1 and SIM2, then turn it back on, you should not see that problem
I know because i was playing around with multiple SIMs when we were researching the Unlock methods for this phone
I take out the battery before I change the SIM. I have to for the Omnia 2 so I just got in the habit. This is sounding worse and worse
although I was rushing off to work so maybe I didn't - hope springs eternal.

sometimes you just have to call Bell, wade thru the 1st level support and get to someone who knows what's up. Apparently my phone plan changed today (I didn't know it was post dated) and the data feature was not provisioned even though it's a plan that includes data. The guy invoked the feature and poof - data. yay. AllGamer, thanks for your help.
you'r welcome
I did have the same problem, using 2 numbers from 2 telcos, both sims work fine on my iphone but I9000 fail to recognize 1 of these 2, no matter how I tried, I actually did all crazy things like insert couple paper layers between the sim and the sim slot to create additional pressure on the sim contact circuit.
Suck thing about this is non-recognizable sim has data plan with it, which I want to use on I900, finally I asked the carrier to issue a new sim and all thing work fine. It's a new sim type anyway. You may want to try this if all other means doesn't work.
The fix is easy I use to have a moto milestone and when this happened a simple reboot fixed the data connection.

Hi there,
today i experienced an annoying issue for the 2nd time.
In normal standy use, my phone seems to lose the connection to my provider (if thats wrong, i mean the institution i bought my contract/sim card from).
It really wont reconnect, even if im going to flight mode and back. Only rebooting helps me with this...
It's showing the forbidden-sign in the top left corner, asks me whether i want to find phone networks. I do search for them and i find mine, but clicking it wont help me neither. It shows that the phone cant connect to the network.
For now, only rebooting helped, and it immediately recognized my standard network.
I don't think that it has something to do with signal quality - i am in Frankfurt central at the moment and generally connections of providers seem to be very good in signal quality right here.
regards.
It may be a sim-card problem...try other sims (if available) and if the problem seems to disappear, ask your network provider to change your sim. Usually, on contract, changing the sim card should be free.
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
I.have the issue of secure folder as its not there in my cell phone and when i install it from play store and open it but failed to open as it give the option knox mode failed
I have S10 bought in UK dual sim. I have two sim inserted slot one UK and slot two foreign sim. They both were working fine until recently.
For the last two weeks both have started loosing connection to network. It is for few seconds 5-10 times a day. Initialy this was with foreign sim and this morning the same happened with the UK sim.
I have tried all options in sim card manager, mobile networks and to restart the phone. Still the same.
I have dropped phone twice but this was some time ago so I do not think this is related.
Anyone have experienced something similar on any suggestions how to fix it?
Many thanks

Yes, I keep losing data connection. I have bars but no data, I have a U.S. sim and a UK sim. Sometimes turning on/off airplane mode helps, other times I have to restart the phone only to get yet another annoying notification telling me I have no network connection. I just installed the latest update, we'll have to see if it stops.
I was decided to do factory reset as a last resort but I thought that maybe I will start with other options and I did the Reset network settings.
So far all good. For the last two days no single issue with loosing network connection.
