Hello guys,
I am using the C6903 variant of Xperia Z1 (purchased from Saudi Arabia) in India. However, the phone struggles to connect to the LTE network. The 4G network shows up in the list of networks, but on selecting it, it displays "Could not connect to the network now, try again later.".
So I dialed *#*#4636#*#* and selected LTE only. It did work once and the LTE signal indicator did appear, and internet was working for approx 5 seconds, but the signal was very weak and I lost it very soon. Will check if it is a range issue tomorrow.
Using a custom ROM(Stock based) [MX ROM] and a custom kernel (RockZ1L). Is it a baseband issue? Please help
Update: it seems that my providers representative was lying when he said that the area where I live has 4g signal. Went for a little trip and lte seems to be working fine now.

Hi All,
Got a new xperia Z1 c6906, setup all things, did input correct APN, chose LTE in the mobile setting. But it couldn't get LTE connection, it always go back down to H+ / 3G, always switch between H+ and 3G. just wondering if the baseband problem? or I have to call Fido and ask them to register my IMEI to their LTE network if the phone couldn't do it itself? thx so much anybody can help.
p.s. previously using Samsung SIII, using LTE sim card and sure in LTE area since I didn't move.
*#*#7378423#*#* to check what LTE bands you have.
BTW, you should post this on Z1 forum.

I remember recently after I crossed the border (from US back home to Canada), my phone was not reconnecting to my home carrier. I had gone into that same menu you are showing, and whenever I chose the Bell LTE one, it would never connect. So I stuck with just the 3G one. It connected fine and I automatically get LTE whenever I'm in an LTE zone. ( I wonder if yours will do the same? )
Could this also be a matter of dialling *#*#4636#*#* and going to Phone Info, then scrolling down and checking if LTE is preferred?
Or - going into Settings, More, Mobile Networks, Network Mode and choosing LTE preferred?
Hi
I am in Kolkata India and recently switched from a 2G to a 3G plan with Vodafone Kolkata. Ever since then, my problem is that I am unable to connect to 3G using WCDMA. Neither voice nor data works. If I revert to GSM only, then voice and 2G works fine. Wifi has been fine and my saviour at home.
Phone details: Sony Xperia SP C5302 running Android 4.3 build 12.1.A.1.205.
I have confirmed with network service that it is not a SIM card issue, by carrying out the foll. tests already
1- Signal strength in the area of use : At the time when I am unable to connect to 3G, my colleague sitting in the next desk and using a Motorola phone is consistently able to connect to the same 3G network from his phone. So the network strength must be fine.
2- SIM damaged or dirty - I have obtained a new SIM card as replacement, after this problem started, from my service provider yesterday. But the problem is not resolved.
3- Manual network search and connection - I have tried this many times, using WCDMA only or WCDMA(Preferred) options. In either case, only on rare occasions, the phone was able to connect to a network. However, 3G data connection (H+ icon) did not show and then the phone disconnects from network. On most occasions, when I manually attempt to connect to the 3G network, I get the message "Could not register to the selected network. Make sure SIM is inserted."
3- Trying different SIM/Handset - I have tried out both options of switching SIM and handset.
- My SIM on Motorola handset - connects to H+
- Another SIM on my Sony - momentarily connects, then disconnects and then does not connect to network.
Please let me know if anyone has faced similar issues and found any resolution. Thank you in advance.

I think that there's an option to use 2G instead of 3G in the settings menu, have you checked to see if that is enabled?

That is the WCDMA option I've mentioned about, there was no other setting for this.
Anyways, it turned out to be a hardware problem. Got the "mother-board" replaced for free as it was under warranty & now working fine!

Hello,
Can I use verison version of this phone in Europe (serbia, slovenia...) normally? Can I turn off 4g/LTE if I need and use only 3g/hspa connections? In my region 4g signal is pure and I have a problem with battery and signal. Does secret menu *#*#4636#*#* works of this version of phone? Thank you.
U can use this phone. Just replace with a local sim card. There is an "unrecognized sim" icon constantly in the notification bar, but other than that everything works the same.

I lived in Spain with the g925v and it does work, but only on 2g/3g, no 4g LTE signal. By that time I was running Android 5.0.2, I believe that with the updates the European LTE band is usable now but I can't assure that.
You can turn off the LTE antenna accessing the menu with this code *#27663368378#
