Hi,

I have the acer Z220.

I can choose to see contact from my sim card or from my telephone.

The problem is that some contact were stored several times on the sim card.

You can remove the doubles to see only each contact ones.

But if you check telephone > contacts > you can see all the doubles again.

 

Although in the contact view they only appear once, it shows them several times in phone.

it seems that contact remain stored on the sim card several times and they are not fully removed

 

How can i clear my sim card completely in depth? My contacts are now on the phone memory.

 

thx
