Can I back-up a sim on an old unused one?

[tudor]

I have 5 sims and I would like to be able to back-up them. I've seen the gold and silver cards, but in Romania I haven't seen any for sale so i would do even with only one back-up card.

Is there a possibility to overwrite an already written sim-card?

Give it a try. It should work excepting some prepaid cards who after beeing rejected from the network wont work.

It's not about just giving it a try
I have to buy a sim card reader first(and for me the 10 dollars mean smth this month).

So did anybody try it? Come on, please tell me if you did!

[adrianpopa]

You dont have to buy a sim reader . Use a phone that can store numbers in own memory ( Nokia 6110 or other)

Could you be ONTOPIC?

I want to back-up the NUMBER not the phone numbers in the sim-card... do you get it?

SO, can anybody help me with this?

It's just like cloning 4 sim cards in one sim, but i can live with only one (other) number in a sim.

For example to save an orange number in a cosmorom sim-card, where orange and cosmorom are romanian providers.

Sory, i didnt understand your question. I cant help you with that.

No. You cannot. SIM cards are write protected...

cyclo thanx, even if it's not what i wanted to hear
