There is a plan from 1010. 559 per month. It provide 4 data/call sim. And 2 data only sim. Total 7G data.
It also provide 4200 rebate for you to buy phone.
This is quite a good deal.
This is the main question I asked in this post, to check whether it is better to join plan individually or separately. After the rebate, the monthly fee for this plan is 384 . Seems good to me.
