I have a samsung tocco lite & carnt get on the internet anymore it keeps saying service unavailable but i still got unlimited internet creddit please help me

If your phone displays the 'sim unavailable' then your phone is currently locked to particular network. You need to unlock to use it with other network. There can be many ways to Unlock your phone. As far as i know unlocking by codes is the simple and safe way. I will suggest the website Unlock-zone.com which is doing good service and they were recommended highly in the cell phone forums. I used them to unlock my cell phone. contacted them and within 30 mins i had my unlock code and my phone was unlocked. Hope this helps.

you have to set your MMS messages service...you can set it manually or by your operator and this way is easier just call your customer service sentre of you operator.

You can get the security password from your service provider at free of cost. If your contract period is complete you can ask your cellular operator for the unlock code. But, they do make it very difficult for you to get the code.
You can also visit http://www.unlock-zone.com/ and can see different options there to get unlock code for a price. Choose any price appropriate for you.

You may not have saved the settings for accessing internet from your phone. You will have to contact your service provider, who on demand will send you the required settings. You will have to save each one of them (around 5 settings will be send to you). After saving it, you can access the internet from your phone easily.
Best Wishes. Thank You.

u must contact ur network provider so they can activate ur mms service.

You will need to get the internet connection settings from your service provider. Contact your mobile service provider and download the settings. Also some service providers require you to activate some kind of internet packs before browsing. Check if this is the case with your SP too.

This is a common problem when it comes to unlocked devices onto another carrier's towers. Call the carrier, and get the onfiguration code for WAP,internet access, and also picture messaging. A lot of times, you can fnd the steps and settings on their web site.
Keep those settings to the side, incase you do a hard reset on your phone. You will lose any new settings.
this will do the trick! Keep in mind, there's certain cost for online access and multi-media usage.

Each carrier is different.
