Please help! No 3G connection

I usually used wifi at home/ company, rarely use 3G, so I used to turn it off by using APNdroid.
Today I needed to search something online so I turned my 3G on by using APNdroid. The 3G icon didn't show up. It didn't work even I switched on the "data roaming" in setting, reboot, switch to airplane mode then switch back.....
Anybody can give me some advice?

I'll second this for the battery savings

With APNDroid in the "on" mode, check your APN settings in Wireless Settings > Moblie Networks > Access Point Names. If there is nothing there, try Menu > Restore Defaults.

G2x Wifi Only, Save precious battery

I bought an unlocked G2x yesterday. I'm not using any of the Cellular related features. How can i turn them off? (Not airplane mode, that also turns off WiFi)
I also put in a random prepaid phone sim to remove the "Insert SIM" notification
I want this phone to look normal. but use only wifi. Because theres wifi everywhere and I can get free wifi calling.

I don't think it will make any difference in battery life weather data is turned off or the SIM is just not present. I think there are ROMs for the G2x that allow data to be toggled but I'm not sure.
If you're talking about T-Mo's wifi calling then you need an active T-Mo SIM to make it work.

You can disable mobile data from
setting > wireless & network setting > mobile network setting > Data enable
As long as you are within wifi range and connected it should by default disable mobile data.

You can try going to dialer, dial *#*#INFO#*#*

(scroll down)
"turn off radio"
YMMV though

This.
This is the only way to achieve what you are asking, toggling mobile data still leaves the cell radio active. I do not know if wifi calling will work with the radio completely off though. Try it out and report back, I'm interested to know.

I just followed that, wifi is still connected.
But this is what i mean
see "Cell Standby" and a completely different section "WiFi"

Airplane mode does turn off your wifi but try turning wifi back on. Works on cm7 at least...

[Q] Network preferred type

Hello,
I have a Moto G with Android 4.3 and i want to change the network type preferred, but i didnt found this option, i always used the command *#*#4636#*#* and change to "WCDMA Only" in my old phone (Samsung galaxy y duos, Android 2.3.6).
My data acess always oscillates between 2g and 3g, there is other way to force connection only at 3g ?
Thank you guys

I also wanna know that

"WCDMA Only" should force it to be 3g only. That's on every phone I've had, and it works.

I tried. I downloaded but I don't know where to go in this app. I can't find the options or the menu to change to wcdma only. Can you please do a dummy tutorial for me?
Seriously I've stared this app for hours and still no clue
Sent from my Moto G using Tapatalk

Oh, when you open the app, it's supposed to take you to the menu that you were taking about.
Look and I'm the general or q&a thread, there is another topic about this. Some people are saying theirs are locked from this menu unless they do something else. If I find a link, I'll send it over

Seriously!?
Have you tried to see each option of the app?
I'm gonna try to help you: open the app, there's a menu. The first option should be "Phone Information", tap that.
So you have a lot of information about the radio, your chip, phone number, your provider, cellphone network and more...
Look for the option like "Set prefered network type" (or something like that. I'm trying to imagine how it's written in English, once here I use it in portuguese).
That option is a combobox with a lot of other options to choose. Always use:
"GSM only" (forces to use 2G, saves battery, you can also use that from Android Config Menu)
"WCDMA only" (forces to use 3G, speed up connection, but drains battery)
And "WCDMA prefered" (the phone always try to connect to 3G, but when it's not possible, it gets 2G).
The default option should be "GSM auto (PRL)". Similar to WCDMA prefered, but read this the see difference:
http://forum.xda-developers.com/showpost.php?p=6591742&postcount=2
Be very careful with the other options. CDMA is very different from WCDMA.
CDMA is a different 2G modulation and it's not compatible with GSM neither Moto G.
EvDO is used only in some countries and providers, google to learn about it.
And LTE is 4G connection. I don't know if Moto G radio support that.
Remember: try it in you own risk! I'm not responsable for any connection problems you get. And try not to change nor tap any other option in that menu.
I'm using this app here with any trouble.

Ok, I see this menu, I select my network preferred type but nothing happens...
Am I supposed to do something after select the network type I want?
I mean, the Phone is still changing to 2g...
I'm so frustrated with not being able to force wcdma =/

Problem solved.
Download and install Phone testing from play store.
Thank you guys =]

I am on the same boat. The change I made in (*#*#4636#*#*) - WCDMA prefered - won't save. After each reboot/restart it goes back to GSM PRL.
My G isn't rooted or modified in any way, out of box state with few 3rd party apps.
Maybe is related to APN?

Network mode
HI Friends,
I like to use network preferred mode AUTO (3g/2g),
but from mobile network -> network mode there are only
two option that we can select either "2G" or "3G".
Some days back at first time when I opend this menu
neither of "2G" or "3G" was selected so It was working fine
with by defualt in auto mode.
But once I have selected this option now It is not possible to unselect both
2G as well as 3G and put phone back to auto network select mode.
Can anybody has work around for this.
I tried "Network" app as suggested but not useful for me.

In Settings > Apps you can reset app preferences which deselects 2g and 3g, but not sure it makes any difference. You lose any preferences you set for apps...

Turn off Mobile network without turning airplane mode on!

Hi
Is it possible to Turn off Mobile network without turning airplane mode on?
Want to be able to use wifi to sent messages etc & not my mobile network

I have this setup currently. I use quickshortcut maker LINK from the play store. When you open the app, it default to incremental search. Type in data usage and several results pop up. In there is settings. Under settings, is the 2nd choice called data usage. Choose it, and the next screen lets you try the shortcut you're making. Click it and it should bring up your mobile data screen where you can toggle the data on/off with just one button! PRESTO!!
Enjoy.

Turning mobile data off is not the same as aeroplane mode - your cellular radio is still active and you can send and receive calls and SMS messages.
Assuming the OP really wants no cellular radio, what they need to do is switch on aeroplane mode, and then switch WiFi back on again.

As I said earlier, you need to switch on aeroplane mode, and then turn Wifi back on again.
You can switch on both Wifi and Bluetooth when aeroplane mode is on.

I do not know what you mean

Hello. More details please... Why do u want cell data off? If you set up wifi calling and use the preferred call method of wifi calling you don't need to do what your trying to do.
TRY THE FOLLOWING.....
Turn on Wi-Fi and connect to a Wi-Fi network.
From the Home screen, swipe up on an empty spot to open the Apps tray.
Tap Settings > Connections.
If necessary, slide the Wi-Fi switch right to the ON position.
Tap More connection settings.
Tap Wi-Fi Calling, now Select one of these options:
Wifi preferred
Cellular network preferred
Never use cellular network
Choose never use cellular network, and when u have a wifi connection your phone will use wifi calling not your carrier network.
This is how you do what your trying to accomplish I believe.
