Not worth it even if it’s free
To start my husband loaded the “free” plan and purchased a second one for a second phone but he could only get them to work on one phone. So we purchased plans from another company we knew was reliable. Then on the trip the Gigsky plan glitched continuously, he had to turn the phone on and off and reset with each country and was completely not worth the “free” since we had purchased a second Gigsky plan that was unable to be accessed nullifying the “free” offer.
