Searching from the US, I can't find any official app or widget from Claro that can give you data or SMS usage. There are a number of data monitoring apps/widgets in Google Play, like
Onavo Count, but it won't necessarily know your data cycle automatically--you'd probably have to enter the start and end dates yourself. For more possibilities, search Google Play for "data usage."
SMS Counter is an app that will count how many SMS texts you've sent and received, but again, it'd be up to you to know when your billing cycle begins and ends. For more apps like this, search Google Play for "SMS count."
