Do Cubacel promotions offer the same lifespan extension for my prepaid SIM card as a standard top-up?

Yes. When you recharge your prepaid SIM card during Cubacel promotional periods, you're in for a double treat. Not only do you receive additional bonuses, but your SIM card's validity also gets extended. This ensures that you get more value from your recharge and can use your prepaid services for an extended period. So, in essence, Cubacel promotions indeed offer the same SIM card lifespan benefits as a regular top-up.
