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!

Good to see that you've sorted out the problem!
Hello!
I have been using this phone for a few weeks now on Metro PCS in the PA/NJ area, solid enough H and H+ data for my needs. But now all of a sudden I am stuck on 2g! (EDGE). I have tried all day with APN settings, and what not, but it cannot see the MetroPCS 3G network, only the 2G network. Under the "Mobile Network" setting, under SIM Card settings, I see the ATT 3G network, which is odd. Any advice? Should I try to buy a new SIM card from Metro? Switch to ATT??
I live in the Netherlands and often my signal goes from LTE to H+. Never happened with one plus 3t.
Let's hope they fix this in a updwte
Never mind, it was the area I was spending the weekend, must be having some trouble there because it's back on H+. Mods please close!

Please Help...
Pictures attached..
same problem here.. but little got a bit different
My XIAOMI REDMI 4X phone only can connect to 4G LTE and cannot find or receive 3G / 2G network signal.
Because of this problem i only can use one SIM at a time it coz when i use SIM1 for using mobile data, SIM2 will showing "No Network" this happen cause of SIM2 couldn't get 3G/2G network signal for its connection. Same issue if I switch SiM2 as my mobile data. SiM1 will be "No Network".
I really hope someone here could give me some solution to SOLVE this problem. also the SIM that i use to get mobile data it has problems that its cannot make out and receive any incoming call. Just regular Messaging are working.
another thing MMI short code also didn't work out it will pop-up with error msg like "cannot connect to server or no network connection" something like that.
This problem has haunted me more than a year and i still cannot get it fix. Need help because i am out of budget to buy new mobile phone .:crying::crying:
When 3g or lte is enabled, most of the time i can't make or receive calls. Sometimes calls are aborted. When only 2g enabled this problem is gone. Why?

May be issue with your local network towers, please call and confirm the proper network to be selected with your service provider, in india lots of telecom companies are merging their networks, happened to me too on vodafine, then they suggested me to select Airtel 3G as my network manually (yes vodafone center suggested me to select airtel) and it worked like amazing, no call drops from that day
