📋 What Is the Insufficient Bandwidth Error?
The Insufficient Bandwidth error occurs when you try to execute a transaction on the TRON network — such as a TRX transfer or any basic transaction — but your account does not have enough Bandwidth to cover the data size of the transaction.
When this happens, the network burns a small amount of TRX from your wallet to compensate for the missing Bandwidth. However, if your TRX balance is insufficient to cover the burn, the transaction will fail with an "Insufficient Bandwidth" or "Out of Bandwidth" error.
The Insufficient Bandwidth error is common for users who send many TRX transfers. It's usually easy to fix — wait 24 hours for recovery, or stake a small amount of TRX for Bandwidth.
🔍 Why Does the Error Happen?
The error occurs for several reasons:
Your account doesn't have enough Bandwidth. TRX transfers need ~350 bytes. You have 600 free Bandwidth per day.
Even if the network can burn TRX, your wallet may not have enough TRX to cover the burn (~0.1–0.3 TRX).
You used all your Bandwidth earlier and it hasn't recovered yet (24-hour cycle).
Transactions with memos or additional data consume more Bandwidth.
The most common scenario is: you've already used your 600 free Bandwidth for the day and don't have enough TRX to cover the burn.
🖥️ What the Error Looks Like
Different wallets and tools display the error in different ways:
| Wallet / Tool | Error Message |
|---|---|
| TronLink | "Insufficient Bandwidth" or "Out of Bandwidth" |
| Trust Wallet | "Transaction failed: Not enough bandwidth" |
| TronScan | "Bandwidth not enough" in the transaction log |
| API / SDK | Error code: "OUT_OF_BANDWIDTH" or "INSUFFICIENT_BANDWIDTH" |
Visit TronScan, enter your wallet address, and check the "Resources" tab to see your current Bandwidth balance.
✅ How to Fix the Insufficient Bandwidth Error
Here are the most effective solutions:
Bandwidth recovers 100% over 24 hours. The simplest solution — just wait.
Lock TRX in Stake 2.0 to receive Bandwidth. Best for users who send many TRX transfers.
Ensure you have ~0.3–1 TRX in your wallet to cover the Bandwidth burn.
Your 600 free Bandwidth resets daily. Plan your transfers accordingly.
For most users, waiting 24 hours is the simplest solution. For frequent transfers, staking a small amount of TRX for Bandwidth is the best long-term strategy.
🛡️ How to Prevent the Error
- Check your Bandwidth balance before each TRX transfer using TronScan.
- Track your daily usage — you get 600 free Bandwidth per day.
- Stake a small amount of TRX for Bandwidth if you transact frequently.
- Keep ~0.5–1 TRX in your wallet as a buffer for burn fees.
- Batch transfers to reduce per-transaction Bandwidth usage.
Most users never run out of Bandwidth because 600 free Bandwidth covers ~1–2 TRX transfers per day. If you need more, staking is the way to go.
⚖️ Bandwidth Error vs. Energy Error
| Feature | 📡 Bandwidth Error | ⚡ Energy Error |
|---|---|---|
| Affected Transactions | TRX transfers, account creation, voting | USDT TRC20, DeFi, smart contracts |
| Free Allowance | 600/day | None |
| Burn Cost | ~0.1–0.3 TRX | ~13–15 TRX |
| Fix | Wait 24h or stake TRX | Rent Energy or stake TRX |
| How Common | Less common (free allowance) | Very common (no free allowance) |
Bandwidth errors are rare for most users thanks to the 600 free daily allowance. Energy errors are much more common because there's no free Energy.
❓ Frequently Asked Questions
- Q: Can I send TRX with insufficient Bandwidth?
A: Yes — the network will burn a small amount of TRX (~0.1–0.3 TRX) to cover the cost. - Q: How much TRX do I need to cover the Bandwidth burn?
A: About 0.1–0.3 TRX for a standard TRX transfer. - Q: How long does Bandwidth recovery take?
A: 24 hours for a full recovery from 0 to 100%. - Q: Can I get more Bandwidth without staking?
A: The only way to get more without staking is to wait for the daily reset. - Q: Does a USDT transfer need Bandwidth?
A: Yes — ~350 bytes, but Energy is the primary cost.
The Insufficient Bandwidth error is easy to fix. Wait 24 hours, stake a small amount of TRX, or add a tiny amount of TRX for the burn.
