doctorSIM is a complete rip-off doctorSIM is a complete rip-off. They gave "excuses" as to possible reasons why they couldnt unlock my iPhone 8+ but none applied to my phone. 100% paid for and under no contract. Left my previous carrier after fulfilling my agreement. Paid they $50 for NOTHING!! DO NOT WASTE YOUR MONEY!!!!

Bad service First my iPhone 4 is a iOs 4.3.5 after paying i found out that there was not a working guidance for my ios. Asking about this i was asked to use an other internetprogram! and other answers similar to this. So i asked for my money back, which they declined. Then I was asked to downgrade my phone. So I asked again for my money back. now a month later nothing had happend

Scam service This is a fraudulent service, like others I was told ' I've just heard back from our unlock team and they just informed us that your unlock has been rejected by AT&T, the official reason for rejecting your unlock is always that there was 'account irregularities'. Whilst they won't specify exactly what irregularities they are, it's usually either that you haven't pay your bills on time in the past or you still owe them money and they're worried about not getting their money from you.' total nonsense as I have never missed a payment, its a scam as they ask you to pay another $99 to get a more advanced service

Scam Iunlock pro I had same experience with them I started past 3 month I wanted to unlock iPhone s5 and I Google and I find there web side and web side say $24.99 so I thought is not bad price so I paid $24.99 and also so they charge $13. 00 don't know for what, few month past I did not hear from them so I send a e-mail week after i got e-mail from them give me two choice 1 10 - 15 days unlock more $39.00 2 3 days unlock more $167.00 i was so into it so i select 10 - 15 days and paid more $39;00 after that 4 week past and did not heard any thing from them so i send e-mail to them, after few days gone i got other e-mail asking more money around $70.00, then i got to know it is SCAM and the money i paid i could get new iphone so be care full with IUnlock pro only big time SCAM

DO NOT USE Will not refund money if it doesn't work I also thought this was a great deal since it was GUARANTEED with a no questions asked refund. I even did a chat before buying spelling out my phone and ios information and asked if this was guaranteed. Of course they did and a "No problem refund". It didn't work of course and all they do now is keep offering me chip cards that I know won't work since I already tried that also. I'm disputing with my credit card company. THIS IS A SCAM!!!
