Question about RIM BlackBerry 7730

1 Answer

Blackberry 7730 Hi I bought an unlocked blackberry on ebay...I have put my Vodafone Sim into it and it asked for my sim password which I input, I got back code accepted, however I cannot make a call from it, cannot receive a call and none of my contacts (saved to sim) appear. Am I doing something wrong? It is not a pay as you go sim, it is a regular sim (business) that works in every other unlocked phone I have tried it in. Am not sure what the problem is, can you help please?

Maybe you can try to unlock your blackberry phone using blackberry bold 9700 unlock code for att network. It will make your blackberry unlocked and you can use any sim card on your phone so you can try to look at your data using another sim card.

I have bought a at&t blackberry torch which is locked.how do i open it??


Hello, if your blackberry locked by old password just type any password until you fail 10 times. It will make your blackberry torch 9800 unlocked and reset to default setting. But if you means locked by network, you need blackberry unlock code to unlock your blackberry phone.

There can be many ways to Unlock your phone.As far as i know unlocking by codes is the simple and safe way.You will need the unique MEP Code for your Blackberry 9700 and to get it you can use a website with service for Blackberry unlocking .so you can use a website to Unlock your Blackberry 9700 online instantly - OR local mobile shop .they are mostly using cables to unlock it and the price is higher then on unlocking websites but the result is the same: SIM free Blackberry.

I bought a bb storm 9550 off ebay which has vodafone on it i tried to get it unloked for t-mobile but it may be blocked - what can i do


Hello,

It looks like the telephone is SIM locked.

If you go to Options > Advanced Options > SIM Card and type MEPD.

This will bring up another screen. If the Network option shows "Disabled" then it is unlocked.

If its locked go back to the seller or buy an unlock code online.

Hope it helped.
