On your housekeeping question on why the G&A cost increased significantly. I think mostly, this is related to the, I think, first quarter seasonality in which we were conservative in recognizing the revenue, along with, I think, allocate the -- some, I think, allowance for the best step. But this is longer time, the growth of the -- I think, in terms of allowance for a bit, that's going to be like the growth of the revenue itself. This is -- it means the number of growth going to be moderating around the time.

They reduced the speed of broadband. We can basically entertain them as well on this one. This can also maintain the level of churn. As you can see, the -- although we acquired BC with, I think, the consolidation between this IndiHome with Telkomsel, we're still able to have subscriber growth around 140,000. With this, I think, combined fixed mobile convergence we do expect this number going to increase significantly over the next quarters. So that's I think...
