I bought R SIM 11+ from this site,item is good as described on DHgate website, packing was good and delivery time is also short, I got this within 20 days of my order. I was worried that will it work with my softbank and AU phone because some reviews are not good, but when I tried to use with Iphone6 and iphone 6s, it worked like ***, phone is unlocked as factory unlocked.
It is very simple to use just plug and play.
I think this is the best solution to unlock all locked iphones of any country. It works with latest 4G usim perfectly, 4G network is stable and there is no signal drop.
Reason of review: Fair pricing.
I liked: Product variation.
I didn't like: Website is complicated.
