Very easy to use app
Very easy to use app. Also can use website. Can put money on SIMs from numerous countries within seconds with ease. Pay several ways, I think, but I just use debit card (ATM card).
For the Mexican SIM, the amounts of load are strange, and it seems like there are plans it signs me up for, but I can't really predict what I'll get along with depositing money on my phone.
I took off a star because I think the fees are too high a percentage of the amount of load I put on the phones.
