because I rarely need mobile data, I am using celcom social back 150MB for 10RM no time limit, normally I consume it within 1.5 or 2 months.
the problem is the back don't accumulate if I have 40MB I'll loose them if subscribed again, to make things worse celcom don't warn me when it finished, if I forgot or used sudden data Celcom will charge me per usage 1RM for 1MB and drain my balance.
many time I found myself without balance or data and can't login to bank to recharge.
I don't need monthly data plan, but need data when I'm out or between home and office,
Is there better choice than Celcom social?
best pay per usage data backage, inquiery.
