Overseas data roaming charges can be a nightmare. Even if you are on any of the Singtel’s data roaming plans such as ReadyRoam or DataRoam Saver, you will need to always make sure that you are connected to Singtel’s preferred network operators. Follow the steps below when are traveling overseas, if you have subscribed to a data roaming plan:
Steps to lock in overseas telco network
Step 1: Enable Singtel network lock
How to enable network lock?
- Go to MySingtel App
- Click on “VIEW ROAMING”
- Click on “Manage” and then click on “Settings”
- Under “Data Roaming (Network)”, you will be able to turn on or turn off Network Lock.
What is network lock?
Network Lock protects users from unintended pay-per-use data roaming charges on non-preferred networks by restricting data roaming usage when users are on DataRoam Saver plans.
All ReadyRoam plans come with the ReadyRoam Network Lock by default.
Step 2: Always double-check the network
It is possible that you are connected to a non-preferred network operator even when you are on network lock. This usually happens when you are at a place where the non-preferred operator has a stronger network signal and data roaming usage is restricted by the network lock.
When this happens, you may manually connect to the network operators below.
