[Q] Unable to connect to Vodafone 3G (C5302) - Xperia SP Q&A, Help & Troubleshooting

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!

Cannot enable "Mobile network" after upgrade to latest FW

Hello,
i've just upgraded to the latest official OTA FW 3.08.405.3
Sense3.0 is great, but i cannot turn on mobile network anymore - i tried it both via Quick settings and Wireless settings menus - it cannot be enabled. And even worts is that it doesn't report any error msg and the 3G sign doesn't appear on status bar. There is noting in the log too...
Does anyone has the same problem?
I just wrote a mail to HTC support, but don't know if they track this as support channel...
This is terrible - i can't live without mobile network connection ...please help!

This might sound weird, but is there anything in APN setting?
Try to mess with the toggles. I have had similar problem. I constantly turned airplane mode on/off and switched from GSM to WCDMA. Finally it goes, if this isn't related to apn. Hope i helped.
10x a lot guys !
it didn't recover APN settings after upgrade
I previously checked them, and assumed that check-box is selected, but actually it was not. It should be colored in green, but actually it was in grey
Unable to re-enable Mobile Network for data-only SIM Japan -- possible bug?
Having a similar problem, some more details:
PHONE:
I am using an unlocked (but unrooted) Incredible S from Virgin Mobile Canada with a data-only BMobile SIM in Japan (runs on DoCoMo's network apparently). Android 2.3.3 (Virgin Canada circa August 2011).
PROBLEM:
Mobile Network intermittently gets disabled and cannot be re-enabled normally. APN is fine, SIM card (phone number) is still detected. Toggling Airplane Mode or Wireless Network does not work, Select Automatically returns "unable to connect, try again later", Search Networks and choosing DoCoMo returns "Your SIM card does not allow a connection to this network".
SOLUTION:
Only reproducible solution is to remove data-only SIM, insert voice&data SIM (from my SoftBank phone), now Mobile Network is available so re-enable it, power down and replace data-only SIM. Once restarted Mobile Network automatically enables. Obviously this is not a convenient fix.
Once was fixed by randomly hitting network settings in frustration, but I have not been able to reproduce this solution.
OBSERVATION:
When on wireless, Mobile Network is also greyed out. When Wireless Network is disabled, Mobile Network automatically enables properly (for the most part, at least once I suspect it did not).
Thus I feel like it's a bug, either in OS or DoCoMo's network, but BMobile and HTC both point the finger at each other and have no useful suggestions for me.
ASIDE:
I hear Android 2.3.5 is available for Incredible S, perhaps this fixes the problem. However, this update has not appeared in my updater -- is it possible that because I'm unlocked I've lost access to the update server?
Thanks in advance for any suggestions.
mobile network disconnected
Have also the same problem, tried all the above suggestions but none works. Phone only shows limited service but with x on the signal bar. BUt when i try to tap the sim tool kit, it displays "SIM toolkit not ready or unsupported".
Hope somebody here can help me. Thanks

[Q] glitchy One, wifi not connecting, can't make calls, data very slow

I'm not rooted, and have stock ROM. It's a SIM-Free HTC One. Connected to EE network in UK.
I've got a fairly new issue that I just noticed in the last week. My HTC One is my second phone so I don't use it as much, but I'm at a point where I want to get rid of it due to the following issues:
I can't make calls, it would sometimes connect but i can't hear anything. This doesn't seem to be a network issue as a user with an iPhone5 seems unaffected.
I can connect to my 5Ghz WiFi network, but not the 2.4Ghz one, it just saves the password but won't connect. I've also noticed if i disconnect from the 5Ghz network, restart phone, i can make calls and hear the other side.
Using Data network, it doesn't seem to want to load anything, it shows 5 bars HSDPA and either goes incredibly slowly or just doesn't load at all.
General performance issues, everything would become incredibly slow, stuttery and incredibly annoying to use. yesterday the device crashed and restarted.
Any ideas what I should do? Try a full reset (ugh...) or is the device faulty in some way and I should contact HTC Support?
go to the dialer and type
*#*#4636#*#*
choose phone info, scroll down to the only dropdown box and select the correct setting for your provider ( wcdma preferred if you don't have a 4G contract)
and then back button about 4 times and try it again
It seems to be the way it should be: GSM/WCDMA/LTE Auto. I was in France a week ago and it had serious issues roaming and data roaming, i had to change it to GSM/WCDMA auto or WCDMA only to make it work. and now back in UK, i set it to the same setting it used to be before I left.
On a side note, I have realised that EE is having data network issues in my area. I tried the SIM in another Galaxy S3 and it had difficulties loading websites, but, it COULD make calls without problems.
Also, no crashes as of today on the One, I still can't connect to my 2.4Ghz wifi router. Could the fact that I was using 5Ghz somehow messed something up inside the One?

[Q] Cannot connect to service provider (network unavailable)

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

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.

Only Connects on 2g (Edge) But Fails on WCDMA (H) and LTE.

Hi guys! I've been troubleshooting this issue for a week now. See, my 2-year-old xperia z1 C6903 suddenly lost it's signal doing nothing. And connects only if forced to use only 2g (GSM only) but won't connect when set to LTE/GSM auto (default setting). My sim (GLOBE LTE PHILPPINES) works fine on other smartphones. I tried different SIM cards, same problem. I tried different custom and stock ROMs but same problem, repaired via Sony PC companion, failed. Nothing seems to fix the problem and I'm thinking if its the signal chip inside the phone or if someone's messing up my IMEI. Any thoughts on this?
if you select prefered network type in setting to WCDMA network still in 2G?

yes. it doesn't connect on any other than 2g.
I have ever like that problem.
If a problem because of software I try reflash to version 108 using flashtool.
If because of hardware, maybe signal cable inside phone broken (blue and white cable). Or signal components (in motherboard).
