LTE network - Sony Xperia Z Ultra

Having a problem here. i don't know if its the phone or the network. Im using C6833. I just changed my sim card for a GLOBE LTE sim (Philippine) ., but upon switching on LTE/WCDMA/GSM it will scan network but after 5 mins it will lost its connection and will not scan any network again.. but in a settings of WCDMA/GSM my network run smoothly., can you figure out what is the problem? thanks for your help.,

Sorry for reviving ths post, but I have a problem close to what OP has...
When I click LTE/WCDMA/GSM. It cannot detect any 4G signal, goes to 3G. Then, the option reverts back to WCDMA/GSM.
I tried the SIM card on another phone, and it can detect 4G signal.
Would appreciate any help.

issues reconnecting to mobilicity network -canada, please help!

Hello there I currently have an unlocked vibrant currently on the mobilicity network in Toronto, Canada.
The phone works well, no issues except for establishing and securing a connection with the network provider. Every time I go to an area where it loses service, like parking garages or subways it loses the connection- obviously- but when you get back to an area where there should be service I only connect to the roaming service. This is leading to extra costs since my plan has charges for that.
What I do now is when i go somewhere with no service i switch to flight mode. When i get back where there is service i have to usually turn the phone off and restart it and search for a network manually.
Are there any apps, hacks, or fixes that can stop me from seeing or detecting roaming services, and force the phone to lock on to my network provider's service?
I want to use it only in the current home zones, and if out of one, i accept the fact that the phone does not work at all. I am always in the coverage zone and never want to use it while roaming.
can anyone help?
At the setting, there is an option there Data Roaming, you need to check or uncheck it. Select the option that will prevent you from doing data roaming and that should fix your problem.
On the otherhand, I have a question for you. I have the same phone and same provider, mobilicity. Our problem is the 3g connection. It is spotty sometimes the 3g icon appears and then disappears. Does this happen to you? I noticed the problem occurs when I go under like basement when there is no signal. After resurfacing, I gell signal reception sometimes full but the 3g or data connection won't work. To solve this, we would usually shut down the phone and restart it. Do you experience the same problem? If yes, what was your fix. Thanks.

Same problem here. Any guidance will be appreciated.
I've done the suggestions for Wind but to no avail.
same mobile , same provider , same issue
hai guys i have the same issue , but my thing is more worser than you.....when ever i go to an underground parking my 3g gets turned off and wen i come out from that place i cant able to make or receive any calls .....i need to restart the phone to turn on the signal again...its really weird any one have the solution ?????
Hey all, I have a Vibrant on Wind, this is what I do.
Go to settings.
Wireless and Network -> Mobile Network -> Network Mode ->WCDMA only
This enables that you stick to Mobilicity's 3G network and not roam on the Rogers 2G network.
If you lose signal, you will not roam, but simply not be connected until you move out and pick up Mobilicity's signal again.
Hope that helps.

I found this on Howard forumns:.... I know this post is old but the solution could help someone who recently bought a old for to get used to customization /flashing.>>> Hope its useful

It works!!! It totally works!!!! I love it! Thank you so much guys!!!! Now I don't have to restart my phone EVERY morning as soon as I pull out of the underground garage in my car!!!
Thank you, Thank you, THANK YOU!!!!!!
Dial: *#*#197328640#*#*
Click [1] debug screen
Click [8] phone control
Click [7] network control
Click [2] band selection
This is where you make a change, default setting is [1] automatic, which means it chooses automatically between gsm/cdma (Edge vs 3g). So we are going to change this and set it to wcdma band which is 3g.
Click [2] wcdma band
Click [1] wcdma all []
Now it should display “select wcdma all bands[*]"
Now on the bottom of your phone, click the menu key, it’s the one next to the home key, now click back, menu again one more time, back one more time, this is just to confirm it set to number 2 wcdma band.
Now click menu key one last time, click end.. and you are done. Now to double verify that the phone is locked into 3g, dial in: *#*#4636#*#*
Then click phone information Then scroll down to “set preferred network type” It should now have listed “wcdma only.” PS, if you tried to do a shortcut, and just set wcdma this way first without doing the lock above, it would just go back to gsm/cdma auto once you exit the screen.
Your phone should now be locked into 3g.

Again found on Howard forumns and copied and pasted to word doc. to keep for my mum as she gets the phone.... I got her the the 27.50 holiday plan so she can call anywhere to anyone in North america with unlimited data....coverage is good so far...
P.S. i dont allow roaming as to not incure more charges.
I know this is an oldish thread but.
Trying to fix connection issues and the Dial code does not work for me. It just does nothing when I enter that. The only code that works is *#*#4636#*#* and that does not help me.
Anyone else having this issue and know why it's not working. I have an Amaze 4G. Only posting here about this phone because this is the only thread I could find related to my issue.
Searched all over now. Those codes are to be the only solution and they don't do anything on my phone.
Anyone have answers?
I have a mytouch 4g (it's actually the htc panache) that just suddenly wouldn't connect to the network after I restarted it. When I try to add a network manually, the only option I have is to connect to Canadian roaming...

[Q] My Atrix 4G does't connect to mobile internet

Hello,
I have an unlocked AT&T motorola atrix 4g mobilephone in Spain. If I put inside it a Vodafone SIM card I can connect to the internet (3G) without any problem after setting the APNs, but when I try it with a Euskaltel SIM card (an Spanish virtual mobile network provider that uses the Vodafones network) I can't connect to the internet (3G) even if I set the correct APNs.
The problem is not the SIM card because it works in a Nexus S after setting the APNs, and as I have said, the Atrix also connects to the internet with a Vodafone SIM card. But Euskaltel+Atrix doesn't work.
The wierd thing is that after I set the APNs, or activate the internet roaming, sometimes appears the arrows that it is connected but just for a few seconds and then dissapear, but even with the arrows if I open quickly the web browser it claims that doesn't have internet connection.
I have tried with other ROMs and the same thing happens, and also with an AOSP ROM like CM7 beta, there is no way to make it work.
Does any one have any kind of clue to solve this?
Regards and thank you

Try creating a new apn & call the first field "euskaltel" & the second one "internet", leave the rest as they are, click save & activate it. That worked for me a couple of months ago with a yoigo card.
It doesn't work, but thank you anyway

Not Registered on Network

Woke up this morning with everything working. Got out of bed and place my phone on my desk and turned on my computer. I then looked back at my phone to see i had not service. Confused, i restarted my phone to see if that worked and it didnt. I tried another sim and it didnt work either. i then put both of the sims in a iphone and it worked there. I restored the phone to stock and 2 other roms and it still isnt working. The weird part is when on stock i get signal bars even when their is no sim. When i try to dial out i get "Not Registered on Network"
Any help is great help

Have you checked your Settings? Still got IMEI? ([Settings] [About Phone] [Status]) Phone connected to correct Network Operator? Access Point Names has correct data in it? [Settings] [More Settings] [Mobile Neworks]
Thanks for the responses. I had a rom running on it for a little bit over a week and didnt make any changes since. I also do have an Imei and an apn

It doesnt even show my network operator, thats the weird part it only shows rogers and when i put a sim in for fido (Rogers>Fido) i got service but no h+ even with the correct apn i only got edge
My Network operator doesn't show as a normal either - I do a Search and get (after a wait) Telstra, Optus and Voda - choose Telstra and it pops up a 'Registered on Network' msg.

yeah when i search i only get rogers???? This is the single most awkward thing ive ever seen
EDITTZ Found the problem. The phone switched itself to only look for one band not all. +_+ dont know how it got their and how it pertained through all the wipes but got it working DDDDDDDD
i had the same very exact problem..and yes when its in auto mode it only detects gsm signal so the data is slow signal is E.
i usually use the wcdma only option so that the phone on searches for 3g h and h+ but now when i select that option it only gives me
not registered on network..and no data signal at all.. and also the weird thing is that there is a signal bar on it plus when i scan for
network it searches the other two carrier brand on our country not the sims own carrier. help anyone

Hey xTristinx, glad you got your phone working.
I have the same problem on my Galaxy S, my SIM wouldn't register a network on it but it worked on a different phone. My Galaxy S still gets a signal but always says "out of service". I think this might be a problem because my friend used his SIM card in my phone and it f***** up the bands. Could you give me any suggestions on how you fixed your problem?
Thank you.
