I recently changed from O2 to Three and the new sim is working fine with no issues. Annoyingly in settings, connections it still shows O2 as network provider even though I’m connected to the Three network. I’ve tried re-connecting to the network both manually and automatically and still it shows O2 as network provider. I also tried resetting network settings and no difference. This has no bearing on use and I'm definitely connected to Three, I just find it irritating seeing O2 incorrectly showing. Is this a bug or is there any way to fix this?

Suddenly my touc pro is having issues connecting over any network connection, except activesync/usb.
I get an error popup saying there was a problem connection the GPRS connection. Claiming the modem hang up. In the notification area i only see greyed out E or 3G icons.
I have soft reset, hard reset, reconfigured the connections etc. Still no luck. And my provider claims there is no issues in their net, and my coworkers using the same provider in the same places got not issues.
Using the standard htc rom currently.
Any suggestions?
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
a few days ago I switched from cm to AEX 7.1.2 on my moto g. Whether that has anything to do with it I don't know.
Anyway last night the phone was working fine then this morning I see that the cell network is disconnected and the phone doesn't see the simcard. However when I put in another simcard from a different network it works normally. I switch back to my sim and it works for about 20 seconds where I can make a call or text then it shuts down again and dowsn't recognize the sim then does again once I have switched the sims but only for 20 seconds. I don't understand what is happening to the phone and why it is doing this. I need help. I have tried picking different network modes from the list after inserting this code #*#*4636#*#* nothing has worked so far. I haven't systematically gone through each one at a time yet and the list is quite long. I haven't seen a list of modes that long before there are over 10 of them from auto prl to scdma etc... Some of them I have never heard of like the scdma one. wif and bluetooth are working ok if that means anything. Thanks for any help
Also when I go into settings the network section is greyed out and under prefered network type it says Invalid Network Mode (-1) Ignore. I only tried changing the modes when this problem arose my changing these modes was not the cause
i've had similar issues, when i skipped using mobile data for a long time, my non-data SIM would dropout intermittently. i changed SIM slots didn't solve it either. other SIM was fine in either slot. just before replacing what i thought was a faulty SIM, without turning mobile data on, i just set the problematic SIM for data. that solved mys issue. however, running mobile data on back on the original setting didnt cause any more issues either.
Hey all, thanks in advance for any advice offered.
For some reason my Galaxy S8+ has a greyed out GSM signal bar with an 'x' next to it. As far as I remember the only thing I did was put it to charge overnight. I've tried removing the SIM, still grey, inserting another carrier's SIM (known to be working), still grey, my original SIM also works fine in another phone. Everything else not related to cell service works fine (wifi, bluetooth etc.). I can see the IMEI number in settings as usual.
I've tried resetting the network settings, factory resetting the phone, I've even reloaded the ROM via Odin. No joy.
The phone is pretty much stock, except for the fact that I changed the carrier software from AT&T to Verizon in order to use a particular LTE band. Since I did that, the phone worked fine for several months.
I've only noticed two things odd thus far. After reloading the ROM and downloading a few updates, a game (Empire) appeared from nowhere installed in my app drawer. Also, the Airplane mode icon in the notification shade is light blue, similar to when it's transitioning from off to on. Airplane mode seems to work though, because I can toggle it, and the wifi reacts as such.
I can't search network operators manually (says: Error while searching for networks), changing the network mode does nothing, and none of the secret dialing codes work either. They all say "Mobile network not available". With a SIM inserted, my SIM status menu says, Network: unknown, Signal strength: -113dBm 0 asu, Service state: Radio off.
Sorry if I'm long-winded, but I'd appreciate any assistance at all. Thanks again for taking the time to read.
I had the same issue and I replaced the daughterboard and antennas
Does*anyone know how to get rid of the Vodafone WiFi calling notification? It appears at the top of notification bar and also on my lock screen, when I have poor signal and it connects to WiFi calling mode. I can only mute it for 2 hours at a time. In the notification settings it comes under "IMS service" which is a system app that it is*greyed out so can't be switched off. I never had any notifications when WiFi*calling*was connected with O2 but I do since changing to the N20 and my new carrier Vodafone. I find this irritating.
Did you ever find any joy with this problem?
I'm having the same issue on my Z Fold 2, I've just switched provider to Vodafone from Three and the IMS Service/WiFi calling notification is unable to be disabled.
It must be Vodafone related as I used WiFi calling on three and never had this issue!
No it's still there! I've just got used to it now
Hey,
I'm having the same problem too. As far as I can tell this seems to be an issue unique to Vodafone users - indeed in the Vodafone's network options menu, the ability to turn off these notifications is greyed out. Same sim card into a friend's phone = same problem. My friend's O2 sim card or another friend's EE sim in my phone = no problem. I've raised this with Vodafone repeatedly and the consistent response from their technical support team has been that a) this isn't a problem that has been raised before; b) that it's something that needs to be fixed across the whole network's standard SIM functionality and they can only do that for widespread issues. Both of these answers are entirely untrue. I keep raising it and I've now formally complained about it.
In the meantime, I use an app called BuzzKill, which although isn't free and for me isn't always 100% effective at muting the Vodafone WiFi Calling notifications, it certainly catches most of them so the £2ish was well worth it. Easy set up too (and no, I don't work for them ).
I found out by enter info then enable wifi calling then disable it goes away.
