[Q] cannot connect to mobile network after lollipop - Xperia Z3 Q&A, Help & Troubleshooting

Received the notifcation for softawre update, so I installed latest androip update ver. lollipop 5.0.2 for my z3.
after rebooting I couldn't connect to Mobile network (vodafone Egypt) I tried resetting to factory settings and rebooting. But no use! It is really frustrating

My first idea is to look into your settings under network APN if there is the right APN for internet connection. If not, google the APN for your provider and add it manually.

Thank you for your help,
I Tried modifying the apn value, the problem remains yet, the problem is not just the internet connection. phone calls, messages are not working either.

i have the same problema.... lollipop kill my network signal.... re flash with kitkat and the problema still here...

[Q] Problem with 3G connection after roaming in 2.3.3

Hi there.
I've a problem with my O1.
I've updated it to Gingerbread V20C stock and have a problem with the mobile internet connection.
My mobile operator is H3G italy. When there is no signal under H3G network it swap to another operator for roaming and the 3G connection drop. No problem till there, 'cos i disabled data roaming.
But when the H3G connection come back, it does not connect to internet. I've checked several times for apn parameters and they are ok, and it isn't a network problem for sure.
Any hint?
Sorry for my poor english, i hope you can understand my question as well...
3G problem with GingerLOL 1.5 (Vietnam)
Hi all,
I'm come from Vietnam. I met problem with 3G connection after install GingerLOL 1.5 ROM (http://forum.xda-developers.com/showthread.php?t=1118685).
Everything seems Ok except 3G connection.
Is there any one met the same problem ? If you knew solution for it, pls share it with me.
Thank you very much,
Hi all,
I am sorry, I have just found out the solution.
We should change APN setting, it can't detect it automatic.
In Vietnam, pls refer : tinhte.vn/thay-doi-nang-cap-firmware-280/p500-huong-dan-flash-rom-2-3-3-official-cua-lg-romania-root-753413
Other countries should take Mobile provider factor of your countries.
Thank you,
It's not a apn settings problem. My apn settings are ok and 3g connection work till the telephone lost h3g network and switch to other operator. When it come back to h3g i have the voice services but no 3g connection at all.
1) If you are not in roaming then turn off roaming, if you are in roaming then turn in on see it is working or not.
2) Just select on 2G from setting and check EDGE is working for you or not. If both the the things have same problem then talk to your ISP and confirm another phone has the same problem or you are only one who is facing this problem.
3) Some times your carrier change their APN without any notice so check they have same APN or not.
I'm sure it's not a network problem because other phones or the same phone with Froyo works with no problem at all.
With 2.3 i have 3g connection until i'm in a point where the default operator (H3G italy) have no signal so the telephone switch to the roaming operator. There the internet connection drop (i've disabled data connection while in roaming), but it's ok.
If the telephone switch again to the default operator i have no problem at all with voice services, but the 3G network connection don't come back until i reboot my O1. Other people have the same problem with the same device and the same version of android (lg stock rom) and the same operator (the only one that use roaming in italy).
I've had problems with my 3G connection too. Didn't go out of the country or anything, just turned on and turned off the 3G connection (data). Had to reboot every time it happens.
This seems a known bug with Gingerbread on P500 and h3g italy... Hope they fix soon....
Hi, I have same problem with data connection lost after return from national roaming in Slovakia (oprator O2). I have LG Optimus One with official gingerbread upgrade. Do you have some news about this problem? Thanks

Help Needed: Data Roaming Won't Run, Since update, Stock ROM, confused

My father is using Tab2 (P3100). Running Stock OS, Unrooted. 3G Data Connection from Vodafone Delhi India.
since a month or so back he found a update notice and upgraded the Stock Firmware to Latest 4.1.2 using WIFI
Not sure but might be since then, Whenever he's On Roaming, Data Connection Won't work.
Currently He's in U.P. circle it won't connect, Voda has 3G Service here, And I use it everyday at home/city wide.
Tried following:-
1). Checked APN Settings, they are correct.
2). Checked Data Roaming in Mobile Networks.
3). Tried Switching to GSM Only, and WDMA Only, WCDMA/GSM Auto Option, All options same result.
4). Checked wifi is OFF, and Data Connection IS Enabled, using Widgets or APPS but it won't turn on
5). Took out the SIM from Tab2, and Inserted In my Android Phone and 3G/2G Connects Instantly.
6). Put A different SIM which is from my Region but as its not On Roaming, Data Works fine.
7). Checked with operator they have no clue whats wrong in the TAB.
8). Requested Fresh APN Settings from Operator and saved it, But Tab2 won't connect.
Can someone shed some light if this is a BUG in current latest firmware of Tab2 or I am getting and my brain fails to finds a solution.
Any help will be appreciated, don't let me down my fellow members pleaseeeeee

Verizon Galaxy S6 G920V lost LTE and ability to edit APN

Hello all and thank you for your time,
I recently updated my Verizon GS6 from Lollipop to Nougat using the Verizon Wireless Software Upgrade Assistant because the update wouldn't occur using the phone's update software feature. Since updating I've lost the ability to use the LTE network by any means at all. I have no data whatsoever, as the APN settings have been altered through this update. I am registered to Straight Talk Wireless and the phone is trying to connect to Verizon using a generic APN. I'd love to change the APN setting but the phone will not allow me to edit anything but the name of the APN. Adding or editing further is completely colored out.
So far I've tried:
1. Soft resets
2. Hard resets
3. Wiping the cache
4. Swapping SIMS of all 4 networks
5. Turning Wi-Fi on and off Turning Mobile data on and off
6. Searching all throughout the internet for answers
So if no one has the answer how to fix this situation is it possible to reverse my update and head back to Lollipop? Is it possible to root the phone to somehow access the APN settings by other means?
Any help would be greatly appreciated as I need to use data for my job.
Thanks!

Unable to automatically setup my o2 germany APN

Hello,
I'm unable to setup my xperia 5 ii (2 weeks old) internet data connection on my o2 prepaid network.
Has anyone faced similar situation? is the manual APN settings the only way to setup data? I think so from my experience after few tryouts.
Also on "Network and Internet", whenever i click the SIM1-O2, the settings app crashes. : Solution: i had to factory reset the network settings to get back this setting up.
Thanks,
Go settings mobile and network then it 2nd option also get in touch with network and ask them to manually send the settings over
