Hello Sanju
I assume there might be MMS settings which you need to get from your service provider.
You can try these steps
Click on Settings ' Wireless and Network ' Mobile Networks - and ensure "Use packet data" is on.
Also.. in the same menu window - enter Access Point Names and ensure that you have your network provider's MMS APN configuration in there. Some network providers can send the configuration to you by their website or a phone code.
Some network providers might request you need to have at least a WAP or Internet APN (Access Point Name) configuration before MMS gets delivered to your mobile phone... if the above still doesn't help you download MMS, install a WAP or Internet APN configuration through your network provider - (by: Naith_KK)
Hope this should do the trick.

Seems like your phone is functioning correctly.

You have disabled wi-fi so it is asking whether you wish to use Phone Data Connection instead. (Standard Practice when trying to access data services)

What you need to do is un-tick the option in options Use only 2g networks. (3g is the mobile data service) That should then allow you to access Mobile Data. (3g)

Also enable data enabled

1. Go to Settings->Wireless & Networks->Mobile Networks->Access Point Names

2. Click Menu->New APN and follow the setting below (leave settings as is for those not mentioned)

• Name: Globe Internet
• APN: http.globe.com.ph
• APN type: default

3. After saving the settings above, select the newly created APN (green radio button appears).

Your phone is now configured to use the newly created APN.

Your Motorola CLIQ MB 200 has an Android OS. Here's how to configure the internet on your phone:
Go to 'Menu'. Choose 'Settings'. Choose Wireless & networks Select Mobile networks. Go to Access Point Names. Press the Menu button. Tap New APN.
Supply the following settings for Globe Telecom:
Name: GLOBE (or anything you want) APN: http.globe.com.ph LEAVE THE REST OF THE FIELDS AS-IS
I hope this would solve your internet connection problem.
