Is this CoreESIM plan for Kazakhstan also valid in other Central Asian countries like Uzbekistan or Kyrgyzstan?

This specific CoreESIM plan is strictly geo-restricted for use within Kazakhstan only. Travelers embarking on multi-country 'Silk Road' tours, often combining Kazakhstan with destinations such as Uzbekistan (e.g., Tashkent) or Kyrgyzstan (e.g., Bishkek), should be aware that their data connection will terminate upon crossing international borders. For seamless regional travel, CoreESIM advises purchasing a dedicated multi-country Central Asia eSIM or individual country-specific plans.
