tipWhen leaving Brazil, maintaining a Correios (Brazilian Post) phone number requires proactive management to avoid deactivation.
A common recommendation is to top up the account periodically (e.g., every 2-3 months) with a small amount (15-30 BRL) to keep the number active. If the balance remains zero for approximately 70 days, the number may be deactivated. Checking for specific commands to monitor balance and payment dates is also advised.
