ifyou have bluetooth that always helps. =]
Put the SIM card from the new phone into the old one. Copy the contacts from the old phone's memory to the SIM card. Put the SIM car back in the new phone - then - either copy the contacts to the new phone's memory - or leave them on the SIM card. Either way - the new phone will find them.
When you get a sim card, it has it's own unique telephone number on it. When you insert the sim card you have that number. You can however get a code and keep your existing number and use it with a new sim card.
If the phone is from the same carrier then yes, it is very simple. If you were to try and put, for example, a T-Mobile SIM into a Cingular phone or vice versa, you will need to "Unlock the phone" first.
if you write your Sim card code or PUK code incorrectly many times your whole Sim card is blocked!! i suggest you should get new Sim card instead.
You do not unlock a Sim card; you unlock the phone To do this without modding the phone or getting an unlock code, you can go and purchase a Sim card add-on such as Turbosim or Hypersim.
coping numbers is easy you copy numbers to phone and send by bluetooth or with same carrier ( say both are AT&T or sprin) move sim card to new phone and copy the new phone from sim card use your user manualto do this because all cellphones are setup different.
