A fantastic service from beginning to end. From once I inserted the sim into my phone upon arrival at the airport, I was able to make calls nationally and internationally, check emails, browse the web and use google maps. I would recommend SIMS 4 USA for your trip to the US.

Highly recommend, I paid twice by accident, they double checked with me by email, refunded me straight away and my sims were in Ireland in 2 days! There was a E6 customs charge but I was expecting some kind of charge with FedEx. Brilliant Service and looking out for their customers! Thank you 🇮🇪

Simple process, all we had to do was insert the new SIM cards. Worked flawlessly from the moment we landed. Would recommend to anyone visiting the US.

This is the first time I got a prepaid card to use while in the States and the experience has been great. Sid Dee was a great help in trying to contact me and activating the SIM card for me. Thank you Sid for your help!!
