I have a Sim card But do not no the number how can I find the number by using my phone?

stick the chip in a phone and call another phone the no. will come up on the phone you call if caller id is switched on

This is how you can check if you have a Nokia >Menu>Contacts>My Number It should be along the same lines in other phones. What phone do you have?

You can call another phone and it should come up on caller ID. If that doesnt work go into settings and go to information or handset information.

call another cell phone with it... the number should come up on the other cell phone's caler id display.

Phone a friend's mobile phone and get them to tell you the number that came up on their side.

RING HOME, DO 1471

This is dependant on the network. 1. Checking through the Mobile's Menu's 2. Contacting the Network (check call rates) 3. It should usually say on the plastic holder I think it is Vodaphone that will provide the number, by checking through the Menu's. When calling the network, you will need to provide them with the serial number of the sim card, this will be printed on it. Gemini_DJ.

Call the SIM card provider and give them the serial number/digits they can tell you the number.
