Judging from all the prepaid and postpaid plans they have introduced over the last few months, i don't think they will.

Having been a DiGi user for 13 years now and a Maxis user on and off over the years, Maxis after all, do have a more stable service compared to DiGi. I do have some issues with DiGi 4G LTE service at major shopping centres such as Mid-Valley Megamall and KLCC where the DiGi 4G LTE signal is on but the internet is unusable. I frequently face such issue at Mid-Valley South Court area, inside AEON Supermarket on LG and near the toilet area near to CIMB Bank/Kim Gary Restaurant but never had any issue with Maxis. Whenever Maxis data becomes unusable it normally is because it fails to connect to Maxis 4G LTE.
1,000 minutes with 4GB data for RM38/month is probably the best deal you can get for a Prepaid plan now. Otherwise another alternative is the U Mobile P38 Postpaid plan but U Mobile internet is really slow most of the times. Unless you're a salesman who only cares about unlimited calls, one is better off staying with DiGi and pay RM38 to DiGi every month.

Still expensive though.

I am looking for a telco which offers unlimited call for Prepaid..

Xpax limits unlimited calls to 10 numbers only for rm7/week. So rm28 per month. Meanwhile P38 gives unlimited calls to ANY NUMBERS at rm38 per month + 4gb internet + unlimited fb, twitter and instagram.

Digi Prepaid

digi website stated rm38 is for 1,000 mins to all network with 4gb  while rm50 is 1,500mins to all network with 5gb internet.. :confused:
