Frequently Asked Questions

General

With Maxis, you will primarily connect to our advanced 4G LTE and 5G networks. These are our high-speed networks, designed to give you the best experience for data-intensive activities like video streaming, online gaming, and fast downloads.

To enhance these modern networks, we have completed the nationwide retirement of the older 3G network.

We also maintain our 2G network which provides essential connectivity for voice calls and SMS, ensuring you can stay connected even in areas where 4G or 5G coverage may be limited.

In summary:

5G/4G LTE: For high-speed data, streaming, and all internet activities.

2G: For basic voice calls and SMS.

3G: Discontinued (retired in December 2023).

You just need to re-register your mobile number at your bank's ATM and other service providers and you should be able to receive TAC/ OTP codes as normal.

A. Check your spam or blocked messages

Look for the OTP/TAC in your spam messages folder

If you’re using Truecaller, check the app’s spam folder as well

Ensure the sender's OTP/TAC short code is not blocked on your phone:
For iPhone: Go to 'Settings' > 'Phone' > 'Blocked Contacts' > Unblock the sender if listed.
For Android: Go to 'Settings' > 'Messages' > 'Blocked Numbers' > Unblock the sender if listed.

B. Enable Premium SMS access

Some Android devices require Premium SMS to be enabled for OTPs to be received. Here’s how:

Step 1: Open 'Settings'
Step 2: Search for 'Special Access' or 'Premium SMS Access'
Step 3: Select 'Always Allow' for messaging services.

C. Send ‘UPDATE’ to the merchant short code.

Some banks and services may require update after switching to new Telco by sending a message to their short code. For example, to update network operator after port in, send ‘UPDATE’ to 66300.

D. Restart your device

Restart your device to refresh your network connection.If you’ve tried all the above steps and are still unable to receive OTP/ TAC code, please get in touch with us via 123.

An increasing number of countries have decommissioned 3G networks to prioritise newer technologies like 4G and 5G. This includes Australia, Singapore, the United States, Japan, South Korea, and others due to regulatory requirements.

Before travelling, we strongly advise checking your destination’s network status, as more regions are phasing out 3G services. In areas where 3G is discontinued, services like USSD (Menu Browsing) and SMS may be limited, as these often rely on legacy infrastructure.

For seamless connectivity, ensure your device supports 4G/LTE or 5G networks
