Open the Helium Mobile Builder application and head to the “Settings” tab. Tap on the “Solana Address” to copy it.
You can purchase Solana (SOL) from any token exchange where SOL is supported and deposit it into your Helium or Helium Mobile wallet using the wallet address found in “Settings”.
Double check the recipient wallet address before you send tokens. It is your responsibility to ensure it is accurate. Once a transaction is completed, there is no way to revert it.
