Fix issue that the wifi calling text cannot be customized based on sim

Some carriers have requirements that the wifi calling text should be
customizable. However, the resources for the wifi calling text are
not obtained based on sim. So it cannot be customized per sim for multi
sim device. To solve this issue, obtain the resources with specified
sim.

Test: manual - Checked that the wifi calling text could be customized
based on sim.
