I was all set to post a negative review but it turned out that the IMEI of the first request was incorrect. (The seller claimed the box as original to the handset which later proved to not be the case. It took finding a decommissioned AT&T nano SIM card to get the correct IMEI directly from the 6 Plus.) Unfortunately it meant paying another US$19.99 for another unlock order but this one was complete within 15 minutes of placing the order. Very reasonable price and unbeatable service. Definitely worth being required to open a PayPal account in order to use the service!
