We're going to Colombia, Peru, Dominican republic, Thailand, Senegal, Italy and South Africa. Or can someone recommend a good international sim card with reasonable rates.

thanks for any advice

I would advise you to buy one sim card for all these countries. If they do not stay that much in these countries it is a good option.

You can consider buying paytoomobile sim card which appears to offer access to these countries that interest you.

You can check their rates and see if they suit you: PaytooMobile - Rates and coverage
