Terms & Conditions

SIM card lifecycle

For customers who have made at least one top up since the date of their SIM activation:

– If the validity of your last top up expires, your number will enter a 60-day inactive period during which outgoing calls, SMS and data will be blocked.

– Once the number has been recycled, you will no longer be the owner of the number or have grounds to make a legitimate complaint/take legal action.

For customers who have not topped up since the date of their SIM activation:

– If a single top up has not been made during the initial 8 days of SIM activation, a SIM will enter a 60-day inactive period during which outgoing calls, SMS and data will be blocked.

– If a top up has not been made during this 60-day period, your number will be recycled and sold to another customer.

To prevent the blocking or loss of your mobile number, please make sure to always top up before the validity of the top up expires. It’s easy to check your number’s status in the SmartNas app. Download SmartNas here for Android or iOS.
