What do I need to unlock my Vodafone?

You need two things to unlock your Vodafone:

  1. Your phone at hand and to be able to access the keypad and drop-down menus.
  2. The IMEI of the phone. The IMEI is a 15-digit number which you can obtain by dialing *#06# on your phone’s keypad.

Is the unlocking permanent?

Yes, once you have unlocked your phone with doctorSIM you will never have to repeat the process. Feel free to restore your Vodafone to factory setting and update the phone’s software as normal.

Can I use my Vodafone abroad?

Yes, once unlocked your cell phone will work on any compatible GSM network in the world. Extortionate roaming fees will be a thing of the past.

Can unlocking a Vodafone cell phone damage it?

No, doctorSIM unlocks phones via IMEI. This is the unlocking method recommended by the manufacturers themselves and does not damage the phone’s software or hardware.

Will unlocking my phone void the warranty?

No, your Vodafone’s warranty will remain intact.

Why unlock my Vodafone at and not at a local phone store?

Our IMEI-based unlocking services are legal, permanent, don’t void the phone’s warranty, and aren’t invalidated by future software updates.

Additionally, your phone is never out of your sight because you unlock the phone yourself by inserting an unlock code.

What happens if my Vodafone is under contract?

You can still unlock your phone even if you have signed a fixed-term contract with your network provider.

You will have to pay your monthly bills until the contract expires or pay an early cancellation fee, but at the same time, you’ll be able to use your phone with other network providers. If you stop paying your monthly bills, your phone will almost certainly be blacklisted by the carrier.
