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?

I NEED A PUK CODE FOR MY BLACKBERRY 8700


Dear Carol, puk code can be found at your sim card package usually written on small paper in your sim card bundling when you bought that phone at first time. However if you can't find that you can call your provider and asking them about your puk code and it's free. That code can be used to unlock blackberry 8700 password and prevent your sim card blocked but you will lose all your previous data in after your blackberry unlocked.

Have just bought s/h Blackberry 8700G plus sim and have made phone calls. Have now downloaded Blackberry Desktop to allow e-mails. On connecting device it now has given me 6 chances to enter Password, but...


Keep continue with wrong password until six times, it will make your blackberry 8700G unlocked from old password. But you will lose all previous data on your phones after that blackberry unlocked and you can setup new password for your blackberry.

Reinstall your blackberry OS, some models need to reinstall their os after unlocked. If your unlocked blackberry 8820 still have same problem, bring that phone to nearest mobile repair shop and asking them to reflash your unlocked blackberry.
