NOT a unlock problem!! "your sim card does not allow a connection to this network"
Sorry i know this may or may not be related directly to the hero but i'm trying to sort out why it happens, so i can fix it.
My phone works fine at home, but when i get to work (and near) I lose data connection, then if i reboot i get the "your sim card does not allow a connection to this network".
This only has been happening for the last two days!! and had been working for months.
Any ideas as the network provider isn't much help?
BTW: the network shows in the "search networks" menu.
well signal and network connection has returned.
Strange thing is, when i checked the networks settings it has automagically changed to "wcdma only" i've changed it back to auto and it disconnected then reconnected fine.
Hmmmm.....????
I'm sorry to tell you this, but the phone has been IMEI blacklisted.

If that were the case it would not work anywhere. The OP reports that the phone works fine from home. He alsl reports that the network connection has returned. Neither of these would happen if the IMEI had been blocked.

ignore that clown
Sounds like the cells in that area may be having some issues, call the network and advise they should be able to take some examples and check the metrica type reporting systems most networks use. This will show alarms triggered by the cell itself and allow the fault to be fixed or reset.
When ever you have an issue and it only happens in one area as its a radio network the issue wont be handset related. In very rare cases certain radio roms can have issues depending on equipment on the base station but its very rare.
Don't worry, I'm not gullible enough to believe him!! Admittedly though that was my first thought before realizing it still worked when i got back home, as the network denied all knowledge of there being a problem. Next I thought maybe it was something to do with my sim......but anyway i never really found out.
I just think it was a bit suspicious that after many calls to the provider and nothing, i thought i'd try again and as i was talking to the 2nd line support it magically appeared back on the network and they said it wasn't them??? hmmm...
If i was to take a guess I think i may have had poor reception in a supposedly good reception area for a while and i had been blocked from connecting via gsm and only 3g (is it wcdma?) or something like that. (i've heard similar has happened to others in the past).
@Anarchyuk: thanks for your insight, its nice to find out how the operators and systems work.
I have found that if I am in an area with no phone reception when I switch from standby i get a warning sign with a picture of the SIM card crossed out and a message suggesting that my SIM card is not working. That is very misleading - all it means is that I have no reception, but my SIM is fine!
I paniced a bit when I first saw it (in an inner office within a large building in a weak reception area) but trial and error has shown it is misleading and I now just ignore it.
Yep, that's normal behavior as far as i'm aware.
The problem i had was completely different, but yes that threw me the first time i saw it as it doesn't obviously look like purely no signal.

This fixed my issue completely. I was set on GSM only and set it to auto, everything came back at once!
Hello everyone.
Since getting a Lumia 800 I've had nothing but issues. Initially the problem was battery life (as is common, I know), which never reached more than 5 hours even on minimum usage. Then I started getting signal dropouts. So I sent it back to Nokia's UK repair centre in Thetford, thinking that they would sort it.
I got the phone back today, and the phone now will not find a network at all - I've tried multiple Microsims on different networks, with no luck. On the advice of the Nokia helpline I restored the phone to factory settings, performed both a soft and hard reset, and tinkered with the network settings app and the mobile network menu in settings.
It isn't a sim insertion error, as a different symbol shows up when no sim is inserted. The phone simply won't find a network, when I know the signal strength is very strong in my area (in fact I'm using my old phone with the same sim card and it has full strength).
It looks like I'm going to have to send it back to Nokia again, but if anyone can help me to save me having to do that it would be much appreciated.
Thanks,
Chris
Try put it on 2G.
Most time 2G get better signal than 3G.

I'd the similar issue, the status kept showing NO NETWORK connection, but the funniest part is, I can make call, and send SMS!
The most frustrated part is, the data connection is always drop! I'm not sure is my telco issue or the phone issue!
Have you tried ringing yourself?
I know that sounds stupid but I constantly get the no signal sign but can still call, send texts and receive all, even the internet works.
I thought it was a problem with three (everyone always says they're ****) but the post above suggests not.

Yeah I'd read somewhere else about ringing/texting to wake the phone up kinda thing, but it doesn't work.
Goes straight to answerphone when I call the phone, and when I try and call out it just fails.

Nope, it's doing this to me on the o2, giffgaff and 3 sim cards I've tried.
Where did you buy it? If it was a physical store I'd take it back there and ask for them to swap it over... would be quicker than sending it to Nokia.
I have the same problem with L800. No service but... I can't call, answer or send sms and get them...(Wifi works fine) I tried many different sim cards from different operators etc. Can't take it back to the shop because I bought it used without purchase papers. It just suddenly stopped saying "no service". And when I mess with it and try search the network manually it finds them, but wont connect to any of them. And after doing that alot, it says incorrect sim or something like that.
It lets me put in the pin code and everything.
I tried searching from everywhere but no solutions yet.

Hmmm, ok it's not a simcard issue then, if you tried a lot of other simcards from different operators, did you try to clean your simcard reader maybe there is some dust or perhaps a failure that results in not reading your simcard.
Goodluck buddy,
So today I made an experiment. I live in Norway and I went to Finland. In Finland the phone worked perfectly with out any problems but as soon I got over the country line back to Norway. It said "No Service". Very strange...

Just kidding mate, it's a strange problem don't think there are a lot of differents between the gsm coverage of both countries.
The only option I can think about for now is to perform a hard reset.
If I found something usefull about this issue I let you know.
Greetz,
Ok so I (foolishly) bought a galaxy s4 with verizon even though I was moving overseas to Israel in two months. I made sure that the phone was world capable (like it can do cdma and gsm) and the guy at the store said it would handle foreign sims no problem. Once I arrived here I got a new sim. I figured out that it needed to be in gsm. From then on it had the service bar and confirmed it was connected to Orange. Since then I have been able to receive calls and texts, but not make them, every time I try to make a call before one ring I get a prerecorded message saying that my number cant be completed as dialed. I have tried several things already to fix this: to a cell phone repair person, to the local sim carrier where a lady tried using the sim of her own phone, customer service at verizon and samsung (who both told me to go see the other). I also did a factory reset which didnt do anything.
my phone is not rooted and is schi545 ME7. I will root if I have to, but if I dont I would prefer not to for the time being
Anyway I suspect the problem has something to do with the fact that I got the phone from verizon. Every time I start the phone I get the Verizon logo and after a minute I get a notification from the verizon set up wizard saying that I have a non verizon sim and that the sims source is unknown. I also tried disabling the verizon security and was able to make the notification go away but the problem persists.
Can someone with experience with this kind of stuff help me please? Thank you so very much:good:
Are you sim unlocked? I don't think the phone is unlocked. Talk to verizon to see if they'll unlock it.
According to verizon I am. I spoke with multiple representives from verizon and they said the phone was unlocked

Has any one told you if you have to change any apn, access point name? That may be the problem too. They can be specific to the carrier.
No, how do you configure that

In system settings, network & wireless, more, mobile networks, access point name. It'll be specific to the carrier so i can't help you there.
all LTE Verizon phones after Galaxy Note 2 are factory unlocked it must be a APN issue. Try maybe to do a factory reset and as previous poster suggested do the steps he told you to change the APN or look into I think it's called HiApn in Play Store.
Also try to put it in global mode or GSM? play with the settings.
still having problems
Thanks for all the input everyone but my problem still persists
I downloaded HiApn and followed its instructions to which told me to set up 3 Apns. I noticed that only one of them can be active at the time. I tried with each one active and I still can not make phone calls. Does anyone have any other ideas?

Go to Setting, call setting, disable the prefix international. I have done the same for using Verizon S4 in Indonesia.
Mine was not unlocked either, although I knew this before buying. This is a guide I tried (without success) to unlock it on my own.
Like the last poster, I reside in Indonesia, but I was never with Verizon. I rooted mine and have had no problems since.
Ok so I went to call settings and the closest I found was assisted dialing for international calls and the option to turn it on or off. I played with that for a bit and it didnt work.
I also tried the code and it said connection problem or invalid code
during my fiddling I came upon an app that showed promise of fixing my problem if I had adb shell. Does anyone have a good place to get that? I tried a few that didnt work out for me. There was another that showed promise but it wouldnt send a package no matter what I try
Thanks
If you want ADB, you need to download Android SDK and have Java Runtime Environment also installed. Then, it is just a matter of typing in "adb" into the command prompt of Windows.
Is there a serious conflict for you not rooting the device? The true benefit of doing this is to get SIM cards from anywhere to work, and to allow certain apps to work. Rooting is simply a matter of bypassing security parameters. As long as you follow instructions strictly, you won't have an issue using the phone as it should be used.
yea I suppose I could try to root it. Im just not great at that stuff and am worried about messing up my phone permanately

You don't need to root. You need to sim unlock. Get a hold of att international chat and adj them for an unlock code.
Hey guys thanks for all the help but I figured out that it was just a bad sim all along and that the first school screwed me over
But everything works now
Brand new unlocked mate 20 Pro. Took SIM out of my unlocked Google Pixel 2 XL. At first the Mate didn't recognize it. Restarted and it connected (4G LTE) and all was good.
Until a few hours later when the phone now has the "SOS calls only" indicator.
Sometimes it will just magically reconnect, other times a restart will get it done. Sometimes a restart won't get it done.
Went into an AT&T store today and after waiting 30 minutes for an associate I was treated to 5 minutes of generic excuses of why there was nothing they could do to help ("It's not an AT&T device" "You may get sporadic service" blah blah blah...
Hoping someone else has this phone and figured out how to resolve this. It's hands down the best phone I've ever owned.

Best bet is to get another SIM, APN settings may be off
I have spotty coverage for making/receiving calls where I live, but no problem with data

We'll order a new SIM, that's all I have
There's another post somewhere about a similar issue with AT&T. I have T-Mobile so the SIM always works fine as soon as you pop it in any phone with compatible bands but the AT&T customer said he had to call customer service and they did something with the IMEI number since this model isn't in their system. You should look for the earlier post--it will probably help.
I know with the op n200 metro version you could put your T-Mobile sim in and unlock the phone to work with TMobile automatically, I can't find confirmation anywhere if this works with the n20 as well, does anyone here know?
I just tried with a T-mo sim card in Metro by Tmo N20 and it didn't work

Was the n20 brand new and the T-Mobile sim inserted before turning the phone on the first time? I read that's how it works on some older phones, I think metro blocked it finally but was hoping it might still work.

yes, I received the phone in mail this afternoon, Brand new and first boot was with T-mobile sim, no service and Mobile network status showed "Disconnected"
The Boot animation did change to T-mobile on a reboot with the sim inside but still no service
As I was playing around with the phone, I stumbled upon a weird way to get signal by trial and error got 4G and 5G data as well but when Wi-fi connected, data seems to switch back to 2G. Let me know if you want to know how

Sure, here it is:
1. Boot the phone with T-mo sim inside the device, once booted you wouldn't have any signal
2. Go to "Sim info & settings" > "Preferred network type" and choose "2G/3G(Automatic)"
3. Reboot the device, once booted you should see signal along with 2G icon
4. Now go back to "Preferred network type" and select "2G/3G/LTE(Automatic)", you should now have 4G (Texts and data works but call dropped)
5. Now switch to "2G/3G/LTE.5G(Automatic)", you should see 5G network (Texts, calls and data all worked fine)
5G was stable for several hours until I connected to Wi-fi and when I disconnected Wi-fi, I noticed that data said 2G.
Let me know if the above steps worked for you

Did you get an incompatible SIM error, or just no signal? Also, you can't just put a Metro SIM in a phone and have it work. You have to call them and tie the IMEI of the phone.

OP is talking about the other way around, T-mo sim in a Metro device
Nord N200 had a bug where the device could be locked to Metro but worked flawless with T-mo sim.
That bug being patched is what OP meant by "blocked"

Yeah, I got that backwards. But if he's not getting an incompatible SIM error with a T-Mobile SIM in the MetroPCS phone and actually getting an edge signal, maybe add a new T-Mobile APN profile. Should work in theory.

Thanks! Good find! Yes I was able to reproduce the behavior. Also in my case it seems that the 5G/LTE will revert back to 2g after some idle time. But I can use the airplane mode to repeat the process (without rebooting the phone) to repeat the process. I was able to reproduce on another metro phone as well. must be some kind of loop hole.

I take it you're not a MetroPCS customer. Must be something baked into the OS. I wonder if it still has the MetroPCS bloatware since it booted with T-Mobile boot animation? Anyway, there are services on eBay that will unlock this phone through the MetroPCS unlock app. I'm not selling anything just letting you know that's an option if you didn't already know.

It installed the T-mo bloatware and removed metro bloatware as soon as it booted. Yeah, I'm not a Metro customer, I'll usually just leave it alone for 180 days and unlock it afterwards

Ah, but you need active service on it for those 180 days to be eligible to unlock it no? And now that it has T-Mobile firmware how can you unlock it from Metro? I'd download the MetroPCS unlock app from the play store and run it to see what it says.

In theory, it's 180 days of active service but in reality, they've been unlocking 180 days after activation. I pay for first month and then throw it back in the box.
Also, I didn't see the unlock app as part of bloatware, its built into settings > about. It'll pull up the same screen as in Unlock app and we can try to unlock from there but obviously, throws the error showing it needs 180 days of service to unlock and is not eligible currently

On eBay it's 75 bucks to unlock. Thats like 2 months of service and you'd be able to use it in a few days instead of having a paperweight for 6 months. Thats what I did on my old Moto One 5G Ace.
