Hello.
Having problems with my I8190N. About 2-3 days a go it suddenly lost ability to connect into internet. I can switch data connection on or off, it doesnt make any difference. I have tried to reflash various ROMs and it's all the same, no internet. I get the usual signal bars but no H/G/E marks.
It did not happen after flashing, had CM11 on it for days and I could connect Internet just fine. No carrier limitations either, I can make calls out and same SIM in my old phone can go to internet.
Should I flash the stock ROM/bootloader back and RMA it? Or is there something else I can do? (perhaps known issue and solvable on my own)
Phone is fairly new, bought it in August as brand new.
i suppose APN settings are correct?
you can try to flash another baseband to try with it, what is yours current baseband?
basebands you can find here for N version, XXAMJ ist newest and working for me...
I had the same problem a couple of days ago. It turns out that my problem was the simcard, have you tried to put another simcard in your phone and see if it works?
I have this problem, same with two phones and two SIM cards, both phones are ZTE, both problem SIM cards are on Vodafone, both phones have no problem connecting to data via t mobile sim? This leads me to believe that voda data does not work on zte phones, apn details are correct. Does anyone knowa fix?
finally sorted it........... f'd around with a few different apn's and even phoned up talktalk(same as vodafone network) who confirmed I had the right settings which I hadnt!
Found the correct settings on the geeksquad website. seems i didnt need to bother filling out some of the fields and then wham internet connection straight away!

Two days ago, out of a sudden my phone stopped connecting to the carrier (Rogers, Canada). I can't call, send text, or use data at all. When I go into Access Point Names, my Xperia Z shows the lterogers.apn installed. If I go into Service Providers I can see a list of Canadian networks, I've tried connecting to the LTE, 3G, and 2G networks of Rogers to no avail. Also, I tried my SIM in a Nexus 5 and it works, I also went to the company and there are no issues with my account at all. Any advice on how to solve this?
same problem

Hey guys
I'm having the exact same problem! Haver only had the phone a month - previous xperia z replaced due to sudden death - and then this morning I lost my mobile data connection, closely followed by my entire reception. I've repaired/reset the phone multiple times, all per Sony's instructions without any luck. Hoping someone around here has a fix for me!!! At the moment just bashing my head against the wall with this phone and its issues!

Have you solved the problem ? I have same issue , after many others...pls help
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.
Can anyone please HELP!... I been searching and looking for an answer for more than 2 weeks..but no resolve.....

How did you get the SIM unlocked in the first place?

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

Hi,
I have an HTC One M7 with it's original Vodaphone ROM (UK, vodap102)
Everything was ok but about 2 days ago suddenly it lost it's cellular network.
from time to time it connects but looses it again the moment i try to enable mobile data.
I have tried to reboot, factory reset, tried different SIM cards (from same company) but nothing.
when i go to network operators sometimes it can't find anything but sometimes it finds all the networks around. when i try to connect to my network it tells me it "Your SIM card does not allow a connection to this network"
I had a firmware update as well (sense 6) but after the update was no change.
Is there anything else i can do?
P.S.
The phone is with unlocked bootloader, S-on and is being used in a different country, not in UK. as i said, it worked perfect for about a year in the same cellular network
Please asist, Thanks.
A little update...
If i choose 2G only, it works fine. but only in this mode.
any suggestions what might it be and how to solve it?
Hello everyone,
I have just recently unlocked my phone because I'm currently away for business in China. However, when i got here and got a new simcard with the local mobile stores my phone cant connect to the networks at all. my phone is rooted and i am quiet a beginner regarding cellphones and what not. any help at all is greatly appreciated
Go to Settings / Mobile / Preferred Network Type.. choose different settings? Maybe you are trying to connect to a frequency that is not offered in China... or click "Choose Network Operator"
yep i did that, theres a choice of three networks, all three for China, two is GSM and one is UTMS, i tried connecting to any of the three and was not successful. automatic select network was also not successful. I bought my phone with Wind
Try inserting that sim card in another phone.Couple months ago i just lost signal with my phone was busting hed for 2 hours try to fix it and eventualy i realized my sim card was dead.
thanks for that, i have my old wind simcard and that works fine I dont think its the simcard's fault because i can still choose to select a network without the simcard in my phone, which still doesnt work.. pretty frustrating.
I was reading something about a HTC phone having the same problem and they solved it using something called a superCID or something like that. Does that ring a bell for anyone?

So you bought phone from Wind, wind simcard works. You put another simcard and it doesn't work?
Your phone is locked to wind. So it won't accept any other simcard aside from wind simcard.
Nexus 6 UK user on EE network. Started to have this problem about 2 mouths ago no signal emergency calls only, reboot the phone still no signal remove sim and put it back in works. This is happening about twice a day. Was running latest stock with root so changed to chroma custom rom thinking it could be radio problem but still happening. Got a replacment sim thinking it was damaged still happening. Phone is over a year old so starting to think hardware problem. Any help would be great.
Cheers
Have you checked your IMEI number?

Hi bushako the IMEI sames okay, I have flashed stock MMB29Q on today with no root to see if it makes any different.
sounds like neither a hardware nor software issue, but a carrier issue.

When you remove and replace the sim card, is the phone on or off? Reason I'm asking is because I'm thinking about a possible problem with the contact pins of the sim card *slot*.
Also wouldn't hurt to check on the sim status next time it stops working.
System settings --> about phone --> (check that baseband version is showing something reasonable, then Status --> SIM Status and check what is under signal strength, cellular network type, service state, cellular network state, and IMEI.
Another thing that you may want to look at, is at System Settings --> wireless&networks/more --> cellular networks --> Preferred network type, and also in Network operators, make sure that you hit the button "choose automatically".
Now, the reason I want you to set it to choose automatically, is because of a glitch I've seen a few times on my service provider here in Canada. If it is set hard to my service provider, occasionally, it will be unable to connect to the network. This is especially the case when I'm *entering* a service area from somewhere that has no service. Note that my service provider uses only ONE MCCMNC, so go figure. Just make sure that you select choose automatically.
You can also try resetting the radio by putting it into airplane mode, counting to 10, and then back to normal.
