I cant access wifi ,and a message appears and it says,could not activate cellar data network,you are not sbscribed to a cellular data service,can you tell me how to fix this

YOU HAVE TO CHECK YOUR NETWORK OPERATOR IN CASE OF YPOUR WIFI IF IT DOES NOT WORK THEN YOU HAVE TO TAKE IT TO THE SERVICING CENTER

unlocked means you can plug in any SIM card from a telephone service provider.
A SIM card, also known as a Subscriber Identity Module, is a smart card that stores data for GSM cellular telephone subscribers. Such data includes user identity, location and phone number, network authorization data, personal security keys, contact lists and stored text messages.
If you have a service provider and a SIM card, then you need access to a WIFI router that is not password protected and will connect to your service provider. Hope that helps.

Assuming you have your Cellular settings setup correctly (cellular data is on and enable LTE for voice and data), possibly need roaming for voice and data to be on, and everything else related to cellular activity like calls and data is fine, then try a "Reset Network" under General, at bottom are the reset options. You'll need your wifi passwords since it resets all networks.

Open your dial pad and dial ##847446# a menu will come up select edit and a box will open, enter 10 zeros in MDN and 10 zeros in MSID then select "ok" the phone will restart then try activating again.

Hi there,
It's important to understand how you can have data connection to your phone so as to access internet e.t.c.

Basics:
1. Access through the Network:
Mobile Providers (Vodafone, e.t.c.) provide data access to the users on request (or by default in some cases). This data access is through the NETWORK of the mobile operator and uses 2G, 3G, GPRS, EDGE protocols to access the network.
2. Access through WiFi or WAN:
A smartphone can access internet using the WiFi or WAN protocol (wireless lan). In order to connect to the WiFi network you need capability from your phone and also to find an Access Point of Wifi (AP) to connect to. WiFi networks are FREE or PAID. You can find free networks usually in central squares, caffee's e.t.c. Also, some providers (Vodafone, e.t.c.) provide WiFi APs and you can use prepaid cards or fixed contracts in order to access them.

Unfortunately your phone DOES NOT support the WiFi protocol, so you can only access internet through the 1st option.
In order to do that, we need that your operator allows the DATA traffic for you and we also need to setup your phone in order to accept/send DATA.

How to do it.
1. Mobile operator settings: Pls call your mobile operator and ask them if your number has DATA allowed (DATA plan, or DATA connectivity). If so, you are OK. If not, pls check the price rates (per MB or per usage time) and -if it's within your budget- ask them to activate DATA to your phone.
2. Phone settings: Your phone has the following symbols that indicate Data connection:
GPRS signal
EDGE signal
In order to setup the Data connection there are the following configuration options in your phone:
1. Menu -> Setup Wizard. Setup wizard can setup your phone for various tasks. Try it.
2. Menu -> Browser Settings. You can select the connection profile to be used for DATA.
take into account that in order to setup a DATA connection you need to setup the AP of the GPRS/EDGE as well (usually something like internet.vodafone.com)

...BUT the easiest solution your you is to call your provider, give your number and phone model/type and ask them to send you an automated message that has all the needed settings for your phone so as to have access to DATA.

You click on the message send and all needed settings are OK.
You can now access internet!







If above solution was helpful, pls rate it.
Thnx.

If your looking to use only wifi at times. You need to go into the setting and shut off the 3g data and have only the wifi option active.

Cellular data over rules wifi at all times. That's their little trick at getting you to use up all your data plan.

Here's the steps:

1. Go to Settings
2. Scroll to Network
3. Cellular Data - slid to OFF
4. Tap General on the top left
5. Tap Settings on the top left
6. Scroll up to Wifi and tap
7. Make sure Wifi is on and finding networks.
(Note: Only networks without the lock are public networks unless you know the pass code to log on)
8. Make sure Ask To Join Networks is to OFF
9. Click the arrow blue arrow on the network you connect too and make sure HTTP Proxy is set to OFF
10. You should Connect just fine

To reverse this and go back to Cellular data. Follow instructions 1 - 5 except you wanna turn Cellular Data back On.

Hi,
TO access your GPRS on china mobile, first go to Settings > General > Network > Cellular Data Network and then input this data:
APN: cmnet

Username: user

Password: cmnet

Don't need to worry about the rest. Make sure that on the Settings > General > Network screen you have "Cellular Data" set to "ON." You need to have already activated the cellular data service through China Mobile first for this to work.

Regards

I believe that you need to call your network provider, and ask them to send you the settings for net browsing. They should send it in a text message. If not, they should be able to help you activate it.
