Hey there, Betty.
Welcome to the Three Community.
You are able to make international calls on your account, however these are not included within your allowances. That means you will be charged to make the calls. Head over here where you can enter the destination you intend to call, and information relating to the charges will be shown.
For unlocking browsing restrictions on the the account, there's a few ways you can do that. Since you don't have the credit card option, you can have the team do an Experian check. You can pop through to the team here to get that done. Alternatively, you can pop in to a local store with photo ID and they can verify you from there.
Pete.
