I took my girlfriends S1 on holiday with my 3 network sim in it, when we came home I put her T-mobile sim back in, now it will not connect to the T-Mob network, it will connect to 3G? Putting the sim in my SNote and all is well. I have since install a custom rom to see if that would help but still no good.

Believe me I have taken the sim out and tried it in the "wrong way" lots of times. I have also looked at your solutions page before, very helpfull. But why will the sim work on one network but not on another, and the non working sim will work in another phone????

Check the modem on both phones.
If the phone that doesn't recognize T-mobile has a different modem, then load the modem that the phone that works has through oden or CWR.
Hope you know how to check the modem and load new ones.
Good luck

This will happen as T.Mobile may be using a different Radio band ..most likely you changed the APN and Network settings when you used it with another SIM Card , whilst abroad ...all you may had to do was check your Network Settings in menu> settings>wireless and Networks> Mobile Networks and reset it back for the T.Mobile network, initially
To understand this better read this http://en.wikipedia.org/wiki/UMTS_frequency_bands
at the same time since you upgraded by flashing to JB, you may have to select a new modem that is suitable for JB, you will find all modems at My Android Collections
Data but no calls
Me back again, I have tried all xx modems, reverted back to stock rom, then GB, them back to CM10. When I first turn on phone it finds network (i'm on a giffgaff sim now) it says GiffGaff at the bottom of the screen for about 2 seconds, then it says emergengy calls only. I can still connect to internet. APN settings correct, IMEI correct, In Settings - About Phone - Status, i'm connected to network, service status = out of service, mobile network state = connected, my phone number = unkown. Where can I go from here?
More
Another thing I have just noticed, when I take the sim OUTwhen the phone is still ON, the "no network" on the screen turns to giffgaff,

Try to set your phone number by following this guide , it was written for a Korean version, so just adjust it for your phone version.

I encountered exactly this issue today.
I wanted to test the data speed from another carrier (same band: 850 Mhz).
It did not detect the data network so I thought "never mind", and inserted my SIM I always used (over 10 months).
It now says "emergency calls only", and when I click to check Mobile Networks in settings, it says no SIM detected. When I insert my SIM into another phone it works.
I tried a few other radios, but it doesn't work.
So what to do with an issue like this?
I have no idea i have tried every possible combination of everything from flashing modding but if a manually choose network it says sim not allowed to register on this network if that helps ive rung both three and samsung with no help x

I need for the 850 Mhz band, and so far only 2 are confirmed to work on this band.
I have tried both, and several others now as well. Now I would settle for SIM card detection and GSM signal...
For example I have tried
Telestra-modem.zip
JK3
JPZ
HKC1
JK5
JPE
None work even for detecting the SIM card.

Yep, same here... the zip says JQ2 but the inside is JQ3, which I assume is the latest release Anyway, for me it works a charm.
I just sent my 10 month old Tab for repairs.
The Samsung service center people and carrier staff were all very surprised it didn't work.
Let me explain why. When I insert a SIM card from carrier #1 on 850 Mhz band it works. I then insert a SIM card from Carrier #2 on the same 850 Mhz band, and it does not work.
I insert SIM #2 into another android phones (tested Galaxy S2, S1, galaxy nexus, and a "dumb-phone")... the SIM works.
Then we tested SIM #3 from the same carrier of SIM #2.... SIM #3 works. Very confusing.
Conclusion.... the SIM card slot is "broken". Nobody knows why some SIM's work, and others do not.
Result. 3-5 days wait for a repaired device or a new device.
Edit: And big thanks to every android custom rom developer out there. Your hard work and diligence allowed me to revert back to a Stock 2.2 ROM, including locked bootloaders, before sending back for repairs.
This is bad news...
I got a call from Samsung and they explained to me that they had to change the entire mainboard. Naturally they didn't have any in stock, and had to order it from Korea, and I'm out of a Tab for 3 weeks.
Hi All
I bought my galaxy note i9220 in China on 18th Aug. It is a genuine phone, NOT a clone just to note.
It was working perfectly fine when I was in China using a China Mobile SIM card.
Last Sunday I went to hongkong to catch a flight to London, and when I was in Hong kong, I changed back to my UK 3 SIM card, which again, was working OK in hongkong.
Before flight took off, I switched the phone off.
During the flight, I must have hit some button and accidently switched the phone on ( as when I landed, I took my phone out and it was “ON” with no signal).
Ever since I landed in Heathrow, I got no signals. The phone shows I can only make emergency calls.
I have tried all of the below but none worked:
1) Switching the phone off & on.
2) Take out battery (while phone was off) & SIM and put them back later.
3) Take out battery (while phone was on) & SIM and put them back later.
4) Reset to manufactory status.
When I go to Setting – Wireless & Network – Mobile Network – Search operator, I can see “3” in the list of operator, but when tried to connect to it, it said “Unable to connect to the network”.
The “3” sim worked fine in my old NOKIA phone so I don’t think it’s a problem on the SIM.
Anyone able to help? Thanks sooo much!
a suggestion..try to make sure you inserted the sim card with the bend angle facing the bottom of your phone..sometimes you insert your sim in a wrong way and this cause your problem..am not trying to be funny but it happen with quite a lot of people including me...
or Could be a fault on your phone..and these things happen..
or your sim is invalid for a reason..i suggest to get a pay as you go 3 uk sim card and try it ...or call 3 customer service and speak to one of their agents to have a look at your account ... they might send you another sim or pop in one of their stores and speak to someone about it...if nothing wrong with your account then am afraid it is a hardware issue with your phone..
Are you sure the phone is not a 4G phone?
This won't work in the UK as our Cell's are different as well.

Got my mum called the phone provider back in CHina they said it should be ok to use in the UK.
They asked me to check my SIM freuency (or sth like this). and said as long as it is on GSM900/1800/1900MHZ, then it should work...what is that???
Try change your network settings between the options, gsm, hspa, and wcdma. Think it's settings, more, mobile networks, network mode.
Probably one of those should sort you out.

When i went into the"mobile networks", the phone started auto search of network.
And it returns network lists:
3
O2 (forbidden)
Vodafone (forbidden)
I understand the 2 being forbidden as im not a custmer of either O2 or VDF, but it just does not allow me even to connect to 3..grrr very anooying.....
I will try changing the settings when i get home today.

For the last weeks.. I have been trying to get this phone working with T-Mobile..I had unlock the sim card and now running badboyz 4.3 rom. 1.3
After unlocking the sim card and setting up the apn, selected T-Mobile from the available networks and it will connect. But when I go to work, I will lose signal every few block, and need to search for available network again and wait to select t mobile again.
I had try to use the t mobile sim card on my old phone and everything will works fine with no signal lost.

This is probably because T-mob covers only particular places the frequencies this phone uses http://theunlockr.com/2013/07/05/htc-one-sprint-specs/ vs t-mob https://t-mobile.jive-mobile.com/#jive-document?content=/api/core/v2/documents/4988

Is there any solution for this problem ?
Is there anything I can do to fix this problem ? (different rom or radio...etc..) Or I have to give up the phone... Cause it is too much headache to "searching for network" all the time and miss all the call with no service on the phone without knowing..
Thanks

well, I am not an expert on the tmobiles network, but going by what lazybozz, said, I seem to remember tmobile using different bands than the other carriers, so what you may be experiencing, is the phone being in the vicinity of multiple towers, but not all of them are within the band that the phone supports. So its like the phone doesnt even see those towers. On a side note, this issue caused alot of chaos for those who unlocked iphones about 3 years ago, they could use EDGE on tmobiles network but not 3G, so i assume this is a similar situation. So long story short, yeah you probably cant fix the problem, unless you get a quad band phone. I could be wrong, but it does sound like a logical reason for the issue you are having.
as elvisypi said above, Its the freq that T-mobile operates on in that area. If your getting T-mobile at all in the states then you have already flashed a radio. However flashing any other radio is not going to give you the freq that tmobile uses, Its not a software limitation its a physical hardware limitation.
Thanks for your reply, do you know any app out there that monitor and alarm you when the network or signal is lost ? That works with 4.3 ?That way at least you know the phone is offline ... some of the apps I tried is anything at all ...
Thanks
Have you tried an app like tasker? Its essentially an automation app. It isnt jist for your use. Its for many different functions. Jist look on the app store for tasker. That might help

Signal? You mean data (3G)?
Have you checked your APN settings under Mobile Netwrks? (I think there was a "More" option). These need to match your carrier's required settings.

Look up the defaults from your carrier and verify everything. I ran into an issue where my carrier changed things around; older SIM cards used different settings than newer cards. If you went online, only the newer settings were listed. I had to do some searching to verify the old SIM card settings.
What network?

i`m on orange (romania). i tried using a vodafone sim as well but it didn`t work.
Ok, the best / weirdest thing happened. I removed the back cover of the phone, now i have full signal. What can it be?! I`ve looked every square inch of the cover and nothing seems to be "wrong" ..

Dunno. If you put the cover back on and it works... Maybe a fluke.
If it doesn't work with the cover on, then it's either a weak antenna, or the cover is putting pressure on something, causing a short.
Just as the title says, the phone was working fine then suddenly it lost all signal and went into some kind of restricted mode, it's a friend's phone and he is almost 84 years old.
I have flashed the latest firmware and factory reset to no avail, also changed sim cards and here comes the weird behavior:
I don't have a standard-sized sim card so I had to take it from my USB LTE Modem, it's from another carrier and the phone detected the sim card, went with a full -77db HSDPA signal but data doesn't work at all, it seems to be disabled on status, even configuring the proper APNs it refuses to work. Can't test voice and all my other working sim cards are nano.
Inserting any other sim from another carrier results in no signal/restricted access but the phone still downloads the Internet/MMS configuration.
Have tried setting it manually to WCDMA and GSM, nothing seems to work, only my data sim worked so far *without the data*.
Maybe the IMEI is banned for some reason?
Never heard of this issue until now
Have you tried to flash a firmware that aren't from any carrier?

Yes I did, flashed the USA unbranded kitkat rom.
Just got the chance to test with two sim cards from different carriers:
Carrier #1: Registered on network, no data traffic, voice call drops just after trying to call, signal ok
Carrier #2: Registered on network, data traffic seems ok but can't navigate, shows H+ and proper APN and traffic arrows activity but when you try a call it says "Mobile Network Not Available"
Can't send SMS, they stick with a "Sending" status and wont get past it.
This phone was purchased unlocked without a contract, can't see how the IMEI could be banned, plus we do not have regularization for IMEI ban in my country, it's currently a mess.
On a side note it does not detect the sim's phone number which it does on any other phone.
Maybe it's some hardware related issue?

The sim number information depends on the sim itself, most carriers register this information within the simcard so when you go to status you may retrieve your own phone number but I have seen sim cards without this info. The sim cards I tested do have this information and were available on a Galaxy S5 and Xperia Z1 but this E1 fails to read this information which kinda indicates a problem. I don't remember the codes for debugging the sim and network info or I'd give that a shoot.
I will try a custom rom, maybe a different kernel and see if the behavior changes any bit.
I am bidding on a Z1 Compact for this friend, should be a proper replacement and a hell of an upgrade, just concerned about E1's loudness which is certainly superior.
Interesting, I also get this if I don't reboot my phone after like 5 days.
