With your new network provider and doctorSIM

If you are thinking of switching to another network, these network providers will help you unlock your phone with doctorSIM for free or with a significant discount. You will be given a coupon code by your new network to unlock your phone with doctorSIM for FREE when you start the porting process.


With your original network provider

If you are patient, know how to configure phones and meet all of the many requirements of your original provider, you can call them and request an unlock code.

Not all network providers issue codes for free, and in some cases you will have to pay for it, nor will they provide any type of support and they definitely won't help you set the phone up on the new network.


However, if none of these options apply to you, we recommend unlocking your phone with doctorSIM.

You won't regret it!
