Expensive choice that works in East Africa but did not work well in the USA
This card may be useful if you travel a lot, but it is way cheaper to buy a local card. I got one to travel in Africa and to use in the USA. The coverage in East Africa was fine, but it was very expensive to run. The coverage in the USA was unreliable and cost was so high that I bought a local pre-pay card for much less. They give no refunds on extra credit if you top-up in case you need it. My purchase of this card ended up being an expensive experiment that was rarely worth it.
