Not Enough Bandwidth on TRON: What It Means and How to Fix It

Seeing “not enough bandwidth” on TRON? Where bandwidth comes from, the 600 free daily allowance, what a transfer uses and how to fix the error.

· 2 min read · TronOrb team

Every TRON transaction takes up space in a block, measured in bandwidth (bytes). If your account doesn't have enough bandwidth and not enough TRX to pay for it, the wallet refuses to send — usually with "not enough bandwidth" or "account resource insufficient". It's the cheapest resource on TRON and the easiest to fix.

Where bandwidth comes from

  • Free daily bandwidth. Every activated account gets a free daily allowance (currently 600 bandwidth). It refills gradually over 24 hours.
  • Staked bandwidth. Staking TRX for bandwidth (Stake 2.0) adds more every day.
  • Burned TRX. If you run out, the network burns TRX instead, at the current bandwidth price (live figure on USDT fee today).

How much a transaction uses

Transaction Bandwidth (approx.)
TRX transfer ~268
USDT (TRC-20) transfer ~345 (plus energy)

So the free allowance covers roughly two TRX transfers or one USDT transfer's bandwidth per day. A USDT transfer also needs energy — that's the expensive part; see OUT_OF_ENERGY.

Why you see the error

  1. You already used today's free bandwidth and the address has no TRX to burn.
  2. The address holds only USDT. No TRX means nothing to burn when free bandwidth runs out.
  3. The address isn't activated yet. Inactive accounts get no free bandwidth. See how to activate a TRON address.

How to fix it

  • Send a little TRX to the address. Bandwidth burn is cheap — well under 1 TRX per transfer.
  • Wait. Free bandwidth refills over 24 hours.
  • Stake TRX for bandwidth if you send many transactions a day. Our energy calculator shows how much bandwidth staked TRX gives right now.

Bandwidth vs energy

Bandwidth Energy
Used by every transaction smart-contract calls (USDT, dApps)
Free daily allowance yes (600) no
Typical cost when burned a fraction of a TRX several TRX per USDT transfer

If a USDT transfer fails, it's almost always energy, not bandwidth. If a plain TRX transfer fails, it's bandwidth.
