I was skeptical at first since there are many sites promising that they are able to remove the sim lock of your phone but turns out to be a scam as you can check for tons of Reddit posts. Therefore I was surprised that they were able to unlock my T-Mobile US iPhone 13 with their Pro service tier. Other solutions like R- SIM don't allow to upgrade latest iOS / prevent eSIM / damage your SIM card slot. Even if you remain skeptical you have no risk offer a refund if unlock fails / accept PayPal.
Thank you very much for your feedback, Vincent! We are very happy to hear that everything worked out as expected and we hope you enjoy the carrier freedom with your unlocked iPhone 13!
