Brand new xperia z1, bought 2 weeks ago in HK, used there for a 10 days with no problem.
Came to japan 2 days ago and now phone drops mobile network after 10-12 hours of stable connection. cannot reconnect, no restart helps. sim card works ok in other cellphone.
Upgraded firmware yesterday to newest one, but with same result - it worked for few hours, but by morning connection to network was lost and cannot connect back.
radio band choice in service menu shows only US band available and even then cannot select it (menu pops up back after selection).
anyone faced similar problem?

I have an ATT Tilt with the official 6.1 ROM specifically for the ATT Tilt. I downloaded it from HTC's website. Start screens shows;
R 1.65.21.18
G 25.88.40.05H
D 3.57.00.00
Phone was working great for months UNTIL yesterday. When I turn the phone radio on it takes several minutes to connect with ATT network. Then I get a message that says "there is a problem connecting to the GPRS network in your area". I can use the phone to make or receive a call, but then after approx 10 minutes with the phone radio on it loses the network connection.
I called ATT. They were less than helpful. They tell me to buy a new phone.
I searched this forum and also googled this problem with no good results.
I have hard reset the phone and still experience the same problem.
Any help would be greatly appreciated.

were is your area.
Central PA. Up until yesterday I had great coverage. Another co-worker with a Tilt can stand right beside me and get service. ATT said it could be the SIM card.
I put my coworkers SIM card in my phone and it took a good 3 minutes to connect with the network. I couldn't keep the card in my phone long (he had to go) but it stayed connected for 5 minutes.
When I turn my phone off and then back on, it will connect to the network after several minutes, but looses the connection shortly after.

If the ATT techs haven't told you to do so already, try System>Connections>Connection Setup
I have done everything included in their instructions at http://www.wireless.att.com/support...0&tutorialsCategory=Browser&tutorialId=614440
but still no luck.
I am having the same issue only recently lots of call drops phone just jumping from 3G to Edge and back again. I also keep getting the login message for MedaiNet.
I live in Tampa, Florida.
Again At&t Tech support was completely useless I am so frustrated that I was actually looking at getting a different phone but I wasn't sure if that would really solve my problems.
Any help/ideas would be greatly appreciated.
Good morning
I bought a new Lg Optimus 4X HD a couple of months ago. Phone non rooted running on latest available android OS. A couple of weeks ago, I started experiencing network loss, with resulting missing important phone calls. This is most annoying. I have tried turning the phone off and restarting, switching from WCDMA to 2G but still the same.
Any help please ??
Set it to auto mode. And set network to automaic.
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
Bought this device 3 week ago. Went for a train ride over a route that I used to use my Sony Xperia Z2. Using the same sim, I noticed the T815 LTE was constantly losing its signal both data (H+ etc) and GSM. I gave it a few week, just in case EE (TPO) was playing games with its signals and masts but no change was noticed. I had rooted the ROM but reverted back to stock, still with no change in the problem. I took it back to the Samsung shop where they replaced the tablet. The replacement is working correctly.
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
