Within minutes of using, you quickly reach a cost / benefit impass. I've been a user for a few years, simply wanting this service to work. It has met expectations on a few occasions, and NOT met expectations of basic voice, sms, data service in over 90% of cases. The solution in all cases, after submitting trouble tickets and seeking help, was to switch to a "local' SIM for trouble free and solid service. The last straw was their new policy to zero your balance if the service is unused for

I could not get the serial number for the SIM sticker, neither method worked on either of two Andriod phones. Even with the help of Tech Support! We ended up swiching to the Knowroaming SIM, which in my case was free with the SIM sticker. SMS usage is difficult to see. Tech support is absolutely 5 🌟, but the app is very buggy, not tested properly. The SIM sticker makes your SIM slightly thicker. Just enough to damage the SIM socket in of my phones. Beware!

Voice and text very unreliable especially in Britain and Europe sometimes texts will continue to repeat send charging you over and over until you delete it. Data mostly works but requires much setup like Provider, KR codes and of course APN. Good features are 3 day gobal packages and unlimited data..... which has just been taken away.
