Can I use the same wallet in other countries?

Yes, you can use your Wallet credit in other countries. But you have to know that the value of the credit you have in your wallet varies from country to country.

When you move from country to country you will find that the numbers vary but have the same purchasing value.

For example, since you have bought 100 credits in State A and want to use them in Country B, but the value of the credit in the first country is doubled compared to the second country, you will find that your credit in State B equals 200 credits in your wallet when you move To State A. Since you have used 20 of your credit in State B, your account credit in State B will be 180, but when you move to State A your account credit will be 90.
