My motorola phone does not support vodafone sim card. As soon as i insert vodafone sim in my mobile it displays sim not registered..!! where as the same sim works in other phones. Plz help me out!!

If you have up your SIM in a Vodafone store, it'll already be activated for you. You can just insert it into the mobile phone and start using it.
If you ordered a free SIM online, you'll need to call 17298 free from your Vodafone mobile to activate it.
Note: Before activating (registering) a Vodafone SIM card, make sure that the mobile phone is locked to Vodafone network or free from network restriction. If it is locked to any other network, you need to unlock it in prior. You can unlock a mobile phone safer and easier using unlock code. If your mobile phone is a Blackberry model, You can visit UnBBLock.Com to get the unlock code. If your mobile phone is from any other model, visit Mobile-Unlocker.com to get the unlock code. Good luck.

How can I use vodafone with other chip apart from vodafone chip

you will need to register your sim card on line or in the phone shop that your sim card is from (if it is from vodafone then take it to a vodafone shop, ect) you will have to do this otherwise you will just keep wasting your money, keep all the credit slips that you have bought and take them with you and explain to them what you have paid for.

Try your sim card to another phone, or try another sim to that phone just to eliminte the problem. Sim card are easily ruin by static discharge

What you will need to do is take the phone to a mobile service center and have it diagnosed to determined the problem
