Dual 4G
If both of your SIM cards support 4G services, when one of
l
them is active on a 4G voice call, you will be prompted to
handle any new call to the other SIM card. Answering the
new call will automatically end the active call.
The default mobile data SIM card can still be used for
l
Internet surfing on a 4G network when the other card is on
a 4G voice call.
Some of the aforementioned features may be
l
unavailable in certain areas due to network
interference.
4G voice services require the support of your network
l
provider and the deployment of relevant services.
Contact your network provider to activate 4G services.
If this guide is inconsistent with the description on the
l
official website, the latter prevails.
