My inital thoughts was that all of the phone unlock web sites are scams. My credit card company double checked with me as they had doubts about the site. Yous looked like the most reliable.
It took 5 days to get a update that the phone was unlocked. I tried a different SIM card and it worked. The phone is unlocked.
I will give you a great review on Trustpilot
Regards,
Mike

Fantastic service from UnlockBase, they even unlocked my iPhone in less than the advertised time of 3-5 days. I would highly recommend them and I will be using this service again in the future. I was sceptical as I had tried one other company who I paid and then looked for more money. UnlockBase five stars thanks again for easy and fluid transaction.
