United Mobile
 

Has anyone used their sim card. They advertise one card that can be used to call from several countries to the USA.

I have, its pricy. However if your going to be in several countries then I have used it because it saves going to get new sim card in each country. If on the other hand your only going to be say in France or Italy its a better deal to get a country sim card.
I have used United all over Eruope and parts of middle east. No problems, good customer service, short learning curve on call back set up, easy to recharge and check whats left on it.

It's many things but surely not "expensive" for the service offered. Been around for years in the Liechtenstein variety and not that long with an IOM Number (UM+).

I've got 4 of those UM+ and 2 Liechtenstein ones.
Etihad airways used to give them away for only a few FF miles!

Customer service sucks, but otherwise no problems lately.

Thanks for the info

I have it. It's one of the most reliable international sims out there. I like Logos, have had it since the +423 Liechenstein number. It has worked in just about every country I have been to from several in the Caribbean to the UK and and West Africa. Compared to most of the other international sims out there, I would take UM over any of them.
