Introduction: The Frustration of a Rejected Token
You bought the credit. You received the token. You typed in the 20-digit code—carefully, painstakingly—and pressed enter. The meter beeped. The lights stayed off. Or worse: it said “successful” but nothing happened.
Few things are more frustrating than a prepaid token that refuses to work. You’ve paid your money, but you’re still sitting in the dark. The good news is that most token failures are fixable. In many cases, the solution is simple and takes less than a minute.
This Accra Street Journal guide explains all the common reasons why ECG prepaid meters reject tokens—from the infamous NURI meter CRC error to CLOU meter upgrade requirements and system-wide technical faults—with step-by-step fixes for each issue.

Part 1: The Most Common Reason – STS Protocol Upgrades
What Is the STS Protocol Upgrade?
ECG has been upgrading prepayment meters across the country as part of Standard Transfer Specifications (STS) protocol compliance . This is a global security upgrade that affects all prepayment meters to ensure the integrity of the token vending system.
What this means for you: If your meter has not been upgraded, it may eventually stop accepting tokens. The upgrade is free of charge and is carried out by ECG officials visiting customers’ premises to electronically update the meters .
Affected Meter Types
| Meter Type | Upgrade Period | Status |
|---|---|---|
| NURI Meters | November 2024 | Emergency upgrade completed |
| CLOU Meters | October-November 2024 | Scheduled upgrade |
| Other prepaid meters | Ongoing | Contact ECG for information |
Part 2: NURI Meters – CRC Error and “Successful” but No Power
Error 1: “The token CRC value is not equal to the CRC calculated”
This is the most common error reported by NURI prepayment meter users .
What It Means: The CRC (Cyclic Redundancy Check) is a built-in verification system that ensures the token you entered is valid for your specific meter. When you see this error, the token is being rejected because your meter needs a system update .
What Causes This: An ongoing emergency upgrade of the NURI Prepayment Meter system, part of the Standard Transfer Specifications (STS) protocol compliance .
The Fix (Relay Reset Method):
| Step | Action |
|---|---|
| 1 | Locate the “Display” knob or button on your NURI meter |
| 2 | Press and hold the button continuously |
| 3 | Wait until the word “Relay” appears on the screen |
| 4 | Release the button |
| 5 | Re-enter your token |
This reset procedure can force the meter to accept the token and restore power .
Error 2: “Successful” but No Power
The meter says the token was accepted, but your lights remain off .
What It Means: The meter has accepted the token but failed to reset the internal relay that controls power flow .
What Causes This: This has been reported by numerous NURI meter customers, often during the STS upgrade period. The meter processes the token but does not apply the credit to restore power.
The Fix:
| Step | Action |
|---|---|
| 1 | Wait 30 seconds |
| 2 | Re-enter the same token |
| 3 | Check if power has been restored |
Some customers have reported success after entering the token a second time .
If Neither Fix Works
Your meter may need the STS upgrade. If you have not been visited by ECG officials, contact ECG customer service at 0302 611 611 to schedule an upgrade . The upgrade is free of charge and is crucial for maintaining the functionality of your metering system .
Part 3: CLOU Meters – The 40-Digit Upgrade Token
Error: Need to Enter 40-Digit Upgrade Token
If you have a CLOU prepayment meter, you may need to input a 40-digit token to reset and upgrade your meter .
What It Means: Your CLOU meter is being upgraded as part of ECG’s STS protocol compliance program.
What Causes This: ECG scheduled system upgrades for CLOU meters from October to November 2024.
Affected Areas Include:
-
Afienya, Nungua, Tema North, Tema South
-
Ablekuma, Bortianor, Korle-Bu, Nsawam
-
Ashiaman, Amasaman, Kaneshie, Dansoman
The Fix:
| Step | Action |
|---|---|
| 1 | Check if you have received the 40-digit upgrade token from ECG |
| 2 | If not, visit your nearest ECG prepayment vendor or district office |
| 3 | Call ECG’s contact centre at 0302-611611 for assistance |
Note: This upgrade is free of charge .
Part 4: System-Wide Technical Failures
Error: “Unable to establish a remote connection to your meter”
This error appears when trying to purchase credit through the ECG PowerApp .
What It Means: The ECG system cannot communicate with your meter remotely. Your meter may be offline, or there may be a system-wide technical fault.
What Causes This: This can be a local issue (your meter’s modem is faulty) or a system-wide issue (ECG’s servers are down). In December 2025, ECG experienced a system-wide technical challenge that affected MMS-compliant meters .
The Fix:
| Step | Action |
|---|---|
| 1 | Try using the USSD code *226# instead of the app |
| 2 | If USSD also fails, there may be a system-wide issue |
| 3 | Check ECG’s official social media (@ECGghOfficial) for updates |
| 4 | Wait and try again later |
Error: “Service is currently unavailable” (via USSD *226#)
When you dial *226#, the system responds that the “Service is currently unavailable” .
What It Means: ECG’s USSD payment gateway is temporarily offline.
What Causes This: This can be due to a system-wide technical fault, scheduled maintenance, or network issues between ECG and mobile money providers.
The Fix:
| Step | Action |
|---|---|
| 1 | Wait 15-30 minutes and try again |
| 2 | Try using the ECG PowerApp instead |
| 3 | Purchase from a physical ECG prepayment vendor |
| 4 | Check ECG’s social media for outage announcements |
If You Already Paid But Received No Token: Check your mobile money transaction history. If your account was debited, contact ECG customer service at 0302 611 611 to retrieve your token or request a refund .
Part 5: User Errors – The Most Common But Avoidable Causes
Cause 1: Wrong Meter Number
One of the most common reasons for token rejection is entering the wrong meter number when purchasing credit .
The Fix: Double-check that the meter number on your purchase receipt matches the number displayed on your meter.
Cause 2: Incorrect Token Entry
Tokens are long (usually 20 digits). It’s easy to mis-type one digit .
The Fix: Try entering the token again slowly, double-checking each digit against your receipt or SMS.
Cause 3: Token Purchased for Wrong Meter
If you entered the wrong meter number during purchase, the token cannot be transferred to a different meter .
The Fix: You must purchase new credit with the correct meter number. Contact ECG to request a refund for the erroneous purchase.
Cause 4: Expired Token
Prepaid tokens typically do not expire immediately, but if you waited an extended period (weeks or months) before using the token, it may no longer be valid .
The Fix: Contact ECG customer service to request a token refresh.
Part 6: App-Related Issues
Error: ECG PowerApp Not Working
The ECG Power App may display error messages or fail to process your token purchase .
What Causes This: ECG has warned that users may experience issues with the ECG Power App during system upgrade exercises .
The Fix:
| Step | Action |
|---|---|
| 1 | Try using the USSD code *226# as an alternative |
| 2 | Purchase from a physical ECG prepayment vendor |
| 3 | Wait a few hours and try again |
| 4 | Check if your app needs an update |
Part 7: Quick Reference Table – ECG Token Rejection Causes and Solutions
| Problem | Likely Cause | Quick Fix |
|---|---|---|
| CRC error | NURI meter needs STS upgrade | Press/hold “Display” until “Relay” appears, re-enter token |
| “Successful” but no power | NURI meter relay not resetting | Re-enter token; if fails, use Relay Reset method |
| 40-digit token required | CLOU meter upgrade in progress | Enter upgrade token or contact ECG |
| “Unable to establish remote connection” | System fault or meter offline | Use USSD *226# instead |
| “Service unavailable” (USSD) | ECG system down | Wait 15-30 minutes; try again |
| App not working | System upgrade in progress | Use USSD *226# or vendor |
| “Invalid Token” | Wrong meter number or typo | Double-check meter number; re-enter carefully |
| No token received after payment | SMS delay or network issue | Check SMS; use PowerApp history; call ECG |
| Payment deducted but no credit | System delay or technical fault | Wait 10-15 minutes; if persists, call ECG |

| Step | Action |
|---|---|
| 1 | Verify your meter number – Double-check against the physical meter |
| 2 | Check your token entry – Tokens are long. Re-enter slowly |

Conclusion: Know the Cause, Fix the Problem
ECG prepaid meter token rejection can be frustrating, but most issues have straightforward solutions .
The most common cause is the STS protocol upgrade affecting NURI meters (CRC error) and CLOU meters (40-digit token requirement). For NURI meters, the Relay Reset method (press and hold the “Display” button until “Relay” appears) often resolves the issue immediately. For CLOU meters, entering the 40-digit upgrade token is required .
System-wide technical failures, while less common, can also prevent token acceptance. In these cases, patience and using alternative purchase methods (USSD *226# instead of the app) are the best strategies .
