Unstake MMS and receive SMS to your organisation’s internal balance.
Converts the specified MMS amount to SMS 1:1 and credits it to the internal balance. Fees, minimum amounts, and monthly limits may apply; consult the Fees/Limits documentation or fees endpoint. Unclaimed MMS rewards are preserved and remain claimable after unstaking.
