For BlackBerry service, customers can only read their emails on the designated BlackBerry device.

Please note that emails received/sent on the first BlackBerry device will not be replicated on the second device.

This is subjected to foreign network restriction. Hence, it is recommended to turn on ONLY 1 device while roaming.

You might not be able to use data on some of your Multi-SIM Cards. This is subjected to foreign network restriction. However you may use any of the devices to receive calls/SMS.
Note: Multi-SIM customers will incur data roaming charges on a per SIM card basis. For instance, a customer with data roaming turned on for 2 devices (and dataroam usage detected on both devices) will incur charges on both SIM cards. If you do not wish to incur data roaming charges, please access My DataRoam Settings by activating My SingTel app > usage to disable data roaming before travel.
I have to use 2 Multi-SIM Cards but only wish to use 1 card (assuming card A) to use data while roaming. How can I do so?

Note: For foreign operators which support 2 simultaneous data sessions, you can use all 2 Multi-SIM Cards for data.
When roaming, will all Multi-SIM Cards log on to the same network?
If the SIM Cards are set to “Auto Selection of Network”, it is possible that the different SIM Cards will log on to different operators/networks. To ensure that they log on to a single operator/network, set the Multi-SIM cards to “Manual Selection of Network” and select your desired operator/network.

Newer devices allow multiple data sessions. For example Blackberry can have 2 data sessions (1 for sending/receiving emails, while another for data/WAP surfing). This is subjected to foreign network restriction. Some of the networks allow only 2 data sessions simultaneously.
