SIM Card Troubleshooting Guide

1. Unable to Access the Internet / Slow Data Speeds

Possible Causes & Solutions:

A. Weak or Unstable Network Signal

Explanation: Being in areas with poor coverage (e.g., basement, elevator, remote regions) may result in slow or no data connection.

Solution: Please check the signal strength on your phone. Try restarting your phone or resetting your network connection. Then move to an open area with better reception and observe if the data speed improves.

B. Data Allowance Exhausted

Explanation: If you have used up your data allowance, you will not be able to access the internet.

Solution: A system-generated SMS will be sent when data usage is nearing the limit or has been exhausted. Please check recent text messages for any usage alerts. It is also recommended to log in to the customer portal to check detailed data usage. If the data has run out, it may be necessary to wait for the next billing cycle or purchase additional data. For further assistance, please contact the support team.
