How to Unlock an E72?

Some networks around the world lock their phones so that users are unable to use a SIM card from a rival network. It is not illegal to unlock your phone, and depending on your network provider, it may involve a fee. For those using a Nokia E72 on Three or Vodafone, you can unlock your phone by calling up customer service. The best reason to give for unlocking when they ask is that  you are going overseas. They will then:

1. Ask for your IMEI number by asking you to type in *#06#2. They give you a code that looks something like #pw+23489729429834+1#3. The phone will say "sim card restriction off"

If you are not with one of these network providers, there are websites which allow you to unlock your phone for a small fee. With some plans that networks lock you into, the fee is usually worth it. Just make sure you do not try unlocking more than three times.
