I’m giving this site a 5 star review for its convenience and 100% authenticity and validity.At first we were skeptical, as we don’t know the authenticity of the site, as we’ve had bad experience from a different site, which we were unfortunately scammed, but again, still we pursued on trying the process at expressunlocks as we needed the phone of my son to be unlocked from its carrier, which was ATT. We were instructed to follow the procedures and and payments. And reading based on other reviews, there are different waiting period or days, depending on the unit that needs to be unlocked. As for us, the waiting time took approximately about 2days to get the whole process done. But we just kept our fingers crossed – trusting the process as they say. 😁 And as soon as we saw flickering bars we see to determine a connection, – that was when my son added his preferred local sim card,- we honestly did some heavy sighs and “phew”! 😁And voila!!! There it was, it was successfully unlocked! All smiles and cheers for this company! Great job, and keep up the good works!👏
