Honest service and quick refund!
I requested an unlock for my iPhone SE from Cricket Wireless. Although the unlock couldn't be completed due to carrier restrictions, the doctorSIM team was very professional and honest about it. They informed me about the situation and processed my full refund immediately as promised. I highly recommend them for their transparency and excellent customer support!

Hello!
Thank you so much for sharing your experience with us.
While we would have loved to successfully unlock your iPhone SE, we believe that being upfront about carrier restrictions is the right way to do business. I'm really glad to hear you appreciated our transparency and the speed of your refund; building trust with our customers is what matters most to us.
We’re here for you whenever you need us in the future!
Best regards,

Hello Mary,
We are truly sorry for the frustration this has caused you. We want to clarify that when an IMEI is rejected, it is due to technical requirements of the carrier or the device's status, not a lack of effort on our part.
At doctorSIM, we have a clear and strict refund policy: if an unlocking service is rejected or cannot be performed, we always issue a full refund of your money. We are a professional team and your funds are guaranteed.
Since we cannot locate your order with your profile name, please contact us at info@doctorsim.com with your IMEI numbers or Order ID. We will personally ensure that your refund is processed immediately so you can have total peace of mind.
We are here to help you 💙
